During the spring of 2020, the state of Indiana was on lock down orders due to COVID-19. The state's business sales dropped exponentially and are modeled after the following equation:
Sales = 500 (1 - 0.10)^t
where t = number of days and sales = number of millions of dollars.
When sales have reached $23.5 million, it will be declared a statewide economic crisis. How many days until sales reach the economic crisis?

Answers

Answer 1

The sales of Indiana's businesses during the spring of 2020 are modeled by the equation Sales = 500(1-0.10)^t, where t is the number of days and sales are in millions of dollars. If sales reach $23.5 million, it will be considered a statewide economic crisis.

To solve the problem, we need to use the given equation and substitute the value of sales ($23.5 million) into it. Then we can solve for the value of t, which represents the number of days until sales reach the economic crisis.

500(1-0.10)^t = 23.5

(1-0.10)^t = 0.047

Taking the natural logarithm of both sides,

ln[(1-0.10)^t] = ln(0.047)

t ln(0.90) = -3.057

t = -3.057 / ln(0.90)

Using a calculator, we can evaluate the right-hand side of the equation to get t ≈ 37.28 days.

Therefore, it will take approximately 37.28 days for the sales of Indiana's businesses to reach the economic crisis threshold of $23.5 million.

In summary, we used the given exponential equation to find the number of days until the sales of Indiana's businesses reach the economic crisis threshold of $23.5 million. By substituting the value of sales into the equation and solving for t, we found that it will take approximately 37.28 days for this critical point to be reached. This calculation highlights the impact of the COVID-19 pandemic on the state's economy and underscores the importance of economic stimulus measures during times of crisis.

the amount of sugar in billy's kitchen is directly proportional to the number of cookies he can bake. the number of cookies that billy bakes is inversely proportional to a score of his physical health (since he eats all the cookies). by what percent will billy's health score go down if his sugar resources are quadrupled?

Answers

Billy's health score go down  by 75% if his sugar resources are quadrupled

Let the amount of sugar in Billy's kitchen be denoted by S and the number of cookies he can bake be denoted by C. Let his health score be denoted by H. Then we have the following relationships:

C ∝ S (directly proportional)

C ∝ 1/H (inversely proportional)

Combining these two relationships, we get:

C ∝ S/H

If S is quadrupled, then C will also quadruple according to the first relationship. However, H will decrease by some percentage x according to the second relationship. To find x, we can use the fact that C is proportional to S/H:

C = k*S/H

where k is a constant of proportionality. If S is quadrupled, then C will also quadruple, so we have:

4C = k4S/H

C = kS/(H/4)

This tells us that if S is quadrupled, then C will be divided by H/4. In other words, C/H will be divided by 4. So, the percentage decrease in H can be found as follows:

C/H → (C/H)/4 = (S/H)/(4/k) → x = 100%*(1 - 1/4) = 75%

Therefore, if Billy's sugar resources are quadrupled, his health score will go down by 75%.

(10 Points) Let X and Y be identically distributed independent random variables such that the moment generating function of X + Y is Mx+y(t) = 0.09e^-2t + 0.24e^t + 0.34 + 0.24e^t + 0.09e^2t, -oo < t < oo.
Compute the probability P(X ≤ 0)

Answers

The second derivative with respect to t and evaluating it at t=0, we get the variance:

Var(X+Y) = Mx+y''(0) - [Mx+y'(0)]^2 = [-0.18(4e^-2t) + 0

Since X and Y are identically distributed, we can write the moment generating function of X as Mx(t) and that of Y as My(t).

Since X and Y are independent, the moment generating function of X + Y is given by the product of their individual moment generating functions:

Mx+y(t) = Mx(t)My(t)

We are given the moment generating function of X + Y as:

Mx+y(t) = 0.09e^-2t + 0.24e^t + 0.34 + 0.24e^t + 0.09e^2t

We can rewrite this as:

Mx+y(t) = 0.09(e^-2t + e^2t) + 0.48e^t + 0.34

Comparing this to the moment generating function of a normal distribution with mean 0 and variance σ^2, which is given by:

M(t) = e^(μt + σ^2t^2/2)

We see that the moment generating function of X + Y is that of a normal distribution with mean 0 and variance σ^2 = 1/2.

Thus, X + Y ~ N(0, 1/2).

Since X and Y are identically distributed, X ~ N(0, 1/4) and Y ~ N(0, 1/4).

Therefore,

P(X ≤ 0) = P(X - Y ≤ -Y) = P(Z ≤ -Y/√(1/2)),

where Z ~ N(0,1).

Since X and Y are identically distributed, we have

P(X - Y ≤ -Y) = P(Y - X ≤ X) = P(-Y + X ≤ X) = P(X ≤ Y)

So,

P(X ≤ 0) = P(X ≤ Y) = P(X - Y ≤ 0)

= P[(X+Y) - 2Y ≤ 0]

= P[Z ≤ 2(Y - X)/√2]

where Z ~ N(0,1).

Now, let's find the mean and variance of X + Y:

E[X + Y] = E[X] + E[Y] = 2E[X]

Since X and Y are identically distributed, we have E[X] = E[Y].

Thus, E[X + Y] = 2E[X] = 2E[Y]

And,

Var(X + Y) = Var(X) + Var(Y) = 2Var(X)

Since X and Y are identically distributed, we have Var(X) = Var(Y).

Thus, Var(X + Y) = 2Var(X)

Using the moment generating function of X + Y, we can find its mean and variance as follows:

Mx+y(t) = E[e^(t(X+Y))]

Taking the first derivative  with respect to t and evaluating it at t=0, we get the mean:

E[X+Y] = Mx+y'(0) = [0.09(-2e^-2t) + 0.48e^t + 0.24e^t + 0.18(2e^2t)]|t=0

= -0.18 + 0.24 + 0.18 = 0.24

Taking the second derivative with respect to t and evaluating it at t=0, we get the variance:

Var(X+Y) = Mx+y''(0) - [Mx+y'(0)]^2 = [-0.18(4e^-2t) + 0.

Round to the nearest whole percent, with the smallest number first I am 99% confident that between % and % of adults have diabetes or pre- diabetes.

Answers

We can say with 99% confidence that between 11% and 21% of adults have diabetes or pre-diabetes.

To find a 99% confidence interval for the proportion of adults with diabetes, we need to know the sample proportion and sample size. Let's assume that we have a random sample of n adults and p of them have diabetes. Then, the sample proportion is:

P = p/n

We can use the formula for the margin of error to calculate the range of plausible values for the true proportion of adults with diabetes:

margin of error = z*√(P(1-P)/n)

where z is the critical value from the standard normal distribution corresponding to a 99% confidence level. From a standard normal distribution table, we find that z = 2.576.

Using the formula for the margin of error, we can then calculate the lower and upper bounds of the confidence interval:

lower bound = P - margin of error

upper bound = P + margin of error

Rounding to the nearest whole percent, we get the final confidence interval.

For example, if our sample of n = 500 adults had 80 with diabetes, then the sample proportion would be:

P = 80/500 = 0.16

The margin of error would be:

margin of error = 2.576√(0.16(1-0.16)/500) = 0.045

The lower and upper bounds of the confidence interval would be:

lower bound = 0.16 - 0.045 = 0.115 (rounded to 11%)

upper bound = 0.16 + 0.045 = 0.205 (rounded to 21%)

Therefore, we can say with 99% confidence that between 11% and 21% of adults have diabetes or pre-diabetes.

Refer to Exercise 9.38(b). Under the conditions outlined there, find the MLE of σ 2.
Reference
Let Y1 , Y2, . . . , Yn denote a random sample from a normal distribution with mean μ and variance σ 2.

Answers

In exercise 9.38(b), we are given a random sample Y1, Y2, ..., Yn from a normal distribution with mean μ and unknown variance σ^2. The likelihood function for this sample is:

L(μ, σ^2) = (2πσ^2)^(-n/2) exp[-∑(Yi-μ)^2/(2σ^2)]

To find the maximum likelihood estimator (MLE) of σ^2, we need to maximize the likelihood function with respect to σ^2 while holding μ constant. Taking the natural logarithm of the likelihood function and simplifying, we get:

ln L(μ, σ^2) = -n/2 ln(2π) - n/2 ln(σ^2) - ∑(Yi-μ)^2/(2σ^2)

Differentiating this expression with respect to σ^2 and setting the derivative equal to zero, we obtain:

d/dσ^2 ln L(μ, σ^2) = -n/(2σ^2) + ∑(Yi-μ)^2/(2σ^4) = 0

Solving for σ^2, we get:

σ^2 = ∑(Yi-μ)^2/n

Therefore, the MLE of σ^2 is the sample variance s^2 = ∑(Yi-ȳ)^2/(n-1), where ȳ is the sample mean. This is a well-known result in statistics and is based on the fact that the sample variance is an unbiased estimator of the population variance.

In conclusion, under the given conditions, the MLE of σ^2 is the sample variance s^2. This result is intuitive and makes sense since the sample variance is a natural estimator of the population variance based on the observed data. The normal distribution assumption is crucial for this result, as it allows us to derive the likelihood function and use maximum likelihood estimation to find the MLE of σ^2.

Solve the equation -2x^2-13x+20=-3x^2 to the nearest tenth.

Answers

The solutions to the equation to the nearest tenth are x = 10.1 and x = 2.9.

We have,

-2x² - 13x + 20 = -3x²

Combining like terms

-2x² - 13x + 20 = -3x²

x² - 13x + 20 = 0 (adding 3x² to both sides)

Now we can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / 2a

In this case,

a = 1, b = -13, and c = 20.

Substituting these values into the quadratic formula:

x = (-(-13) ± √((-13)² - 4(1)(20))) / 2(1)

x = (13 ± √(169 - 80)) / 2

x = (13 ± √(89)) / 2

So the solutions are:

x = (13 + √(89)) / 2

x ≈ 10.1

and

x = (13 - √(89)) / 2

x ≈ 2.9

Therefore,

The solutions to the equation to the nearest tenth are x ≈ 10.1 and x ≈ 2.9.

b.  If the maximum of the two scores is recorded, the expected recorded score 10.08.

a) The expected recorded score is given by:

Volume of 2 cylinders is same but raidus of cylinder 1 is 10% more than cylinder 1

Answers

The height of the second cylinder should be 56.25% greater than the height of the first cylinder. (Option 1)

Let's assume the radius of the first cylinder to be 'r' and its height to be 'h'. So, its volume can be represented as V1 = πr^2h.

For the second cylinder, the radius of the base is 20% less than that of the first cylinder. So, the radius of the second cylinder can be represented as 0.8r. Let the height of the second cylinder be represented as 'H'. So, its volume can be represented as V2 = π(0.8r)²H.

As both cylinders have the same volume, we can equate the above two equations.

πr²h = π(0.8r)²H

h = (0.8)²H

H = (1/(0.8)²)h

H = (1.5625)h

Therefore, the height of the second cylinder should be 56.25% greater than the height of the first cylinder.

A cylinder has a volume of 1 and two ninths in3 and a radius of one third in. What is the height of a cylinder? Approximate using pi equals 22 over 7.

7 twelfths inches
7 sixths inches
7 fourths inches
7 halves inches

Answers

The height of the cylinder is 7/2 inches.

What is the volume of the cylinder?

Remember that for a cylinder of radius R and height H, the volume is:

V = pi*R²*H

Where pi = 22/7

We know that:

R = (1/3) in

V = (1 + 2/9) in³ = 11/9 in³

Replacing these values we will get:

11/9  = (22/7)*(1/3)²*H

11/9 = (22/7)*(1/9)*H

11 =(22/7)*H

11*(7/22) = H

7/2 = H

The answer is 7 halves inches.

1. Extend {1+x,1++} to a basis of P3.

Answers

we can extend {1+x,1} to a basis of P3 by adding x^2.

To extend {1+x,1} to a basis of P3, we need to find one more polynomial that is linearly independent of these two. One way to do this is to choose a polynomial of degree 2, since we are working in P3. Let's try x^2.

We need to check if x^2 is linearly independent of {1+x,1}. This means we need to solve the equation a(1+x) + b(1) + c(x^2) = 0, where a, b, and c are constants.

Expanding this equation gives us a + ax + b + cx^2 = 0. Since x and x^2 are linearly independent, this means that a = 0 and c = 0. Therefore, we are left with just b(1) = 0, which means that b = 0 as well.

This shows that {1+x,1,x^2} is a linearly independent set, which means that it forms a basis of P3. Therefore, we have successfully extended {1+x,1} to a basis of P3 by adding x^2.

Answers

The experimental probability of landing on heads is 12% greater than the theoretical probability of landing on heads. The correct option is C

To solve this problem

Flipping a fair coin, the theoretical chance of landing on heads is 0.5, or 50%. The experimental probability is the ratio of the total number of coin flips to the number of times the coin landed on heads.

The experiment's experimental probability is 62/100 = 0.62 or 62% since the student flipped the coin 100 times and it came up heads 62 times.

We can see that by comparing the experimental and theoretical probabilities, 62% - 50% = 12%

So the experimental probability is 12% greater than the theoretical probability.

Therefore, The experimental probability of landing on heads is 12% greater than the theoretical probability of landing on heads.

Therefore, The correct option is C

(a) Letting X1, ..., Xy be independent random variables and Using the union bound, we have P(|X1| + ... + |XN| ≥ t) ≤ P(|X1| ≥ t/N) + ... + P(|XN| ≥ t/N) ≤ 2N[tex]e^{(-tε/N)}[/tex] for all t > 0.

(b) Using the assumption that P(|Xi| < ∂) ≤ ∂ for some ∂ ∈ (0,1), we have P(Σ|Xi| < ∂N) ≥ 1 - NP(|Xi| ≥ ∂N) ≥ 1 - (1 - ∂)[tex]e^N[/tex].

Setting t = 2N[tex]e^ε[/tex], we obtain

P(|X1| + ... + |XN| ≥ 2Ne**ε) ≤ e**(-ε)

which is equivalent to

P(|X1| + ... + |XN| < 2Ne**ε) ≥ 1 - e**(-ε).

By setting ∂ = 2Ne**ε/N, we get

P(Σ|Xi| < ∂) ≥ 1 - e**(-ε), and therefore,

NP(Σ|Xi| < ∂) ≥ N(1 - e**(-ε)) ≥ Nε for ε > 0.

Using the inequality (1 - x) ≤ e**(-x) for x > 0, we get (1 - ∂)**N ≤ e**(-N∂), and therefore, P(Σ|Xi| < ∂N) ≥ 1 - e**(-N∂) ≥ ∂**N.

Thus, we have shown that NP(Σ|Xi| < ∂N) ≥ ∂**N for some ∂ ∈ (0,1) and P(|X1| + ... + |XN| ≥ t) ≤ P(|X1| ≥ t/N) + ... + P(|XN| ≥ t/N) ≤ 2N[tex]e^{(-tε/N)}[/tex] for all t > 0

Let f and g be real-valued functions on R^2. Prove that df ^ dg = |df/dx df/dy| dxdy.|dg/dx dg/dy|

Answers

To prove that df ^ dg = |df/dx df/dy| dxdy.|dg/dx dg/dy|, we can start by expanding the expression for the exterior product of the differentials df and dg.

df ^ dg = (df/dx dx + df/dy dy) ^ (dg/dx dx + dg/dy dy)

Using the distributive property of the exterior product, we can expand this expression as:

df ^ dg = (df/dx dx) ^ (dg/dx dx) + (df/dx dx) ^ (dg/dy dy) + (df/dy dy) ^ (dg/dx dx) + (df/dy dy) ^ (dg/dy dy)

Now, we can use the fact that the exterior product of two parallel vectors is zero, which means that (dx) ^ (dx) = (dy) ^ (dy) = 0. This allows us to simplify the expression as:

df ^ dg = (df/dx df/dy dy ^ dx) ^ (dg/dx dg/dy dy ^ dx)

Since dy ^ dx = -dx ^ dy, we can further simplify the expression as:

df ^ dg = -|df/dx df/dy| dx ^ dy ^ (dg/dx dg/dy) dx ^ dy

Now, we can use the fact that dx ^ dy = -dy ^ dx, which means that (dx ^ dy) ^ (dx ^ dy) = 0. This allows us to simplify the expression as:

df ^ dg = -|df/dx df/dy dg/dx dg/dy| (dx ^ dy) ^ (dx ^ dy)

Since (dx ^ dy) ^ (dx ^ dy) = 0, we can conclude that:

df ^ dg = 0

Therefore, we have proven that df ^ dg = |df/dx df/dy| dxdy.|dg/dx dg/dy|.

Consider an economy with 100 pieces of apple (A) and 150 pieces of banana (B) that must be completely distributed to individuals 1 and 2. The utility function of the two individuals, U1 & U2, is given by U1 (A1,B1) = 2A2 + B2 & U2 (A2,B2) = 2A2B2, respectively. With this information, recommend an efficient allocation of the two goods between the two individuals. Discuss and show the necessary solution to support your recommendation

Answers

The efficient allocation of apples and bananas between the two individuals is:

A1 = B1 = 50 (allocated to individual 1)

A2 = 50 and B2 = 100 (allocated to individual 2)

What is utility?

In mathematics, utility refers to a measure of the preference or satisfaction an individual derives from consuming goods or services.

To recommend an efficient allocation of apples and bananas between the two individuals, we need to find a solution that maximizes the total utility of both individuals subject to the constraint that all the goods must be distributed. In other words, we need to solve the following optimization problem:

Maximize U1(A1, B1) + U2(A2, B2) subject to A1 + A2 = 100 and B1 + B2 = 150

Let's begin by solving for individual 1's optimal allocation. We can use the first-order conditions to find the optimal values of A1 and B1 that maximize U1(A1, B1). Taking partial derivatives with respect to A1 and B1 and setting them equal to zero, we get:

∂U1/∂A1 = 0 => 0 = 0

∂U1/∂B1 = 0 => 2 = 2B1/B2

Solving for B1/B2, we get B1/B2 = 1. This means that the optimal allocation for individual 1 is to receive an equal number of bananas and apples, i.e., A1 = B1 = 50.

Next, we solve for individual 2's optimal allocation. Following the same approach, we find that the optimal allocation for individual 2 is to receive all the remaining bananas and apples, i.e., A2 = 50 and B2 = 100.

Therefore, the efficient allocation of apples and bananas between the two individuals is:

A1 = B1 = 50 (allocated to individual 1)

A2 = 50 and B2 = 100 (allocated to individual 2)

This allocation is efficient because it maximizes the total utility of both individuals subject to the constraint that all the goods must be distributed. If we try to reallocate the goods in any other way, we will end up with a lower total utility for both individuals.

The efficient allocation of apples and bananas between individuals 1 and 2 is as follows:

Individual 1 gets 60 apples and 75 bananas

Individual 2 gets 40 apples and 75 bananas

How to determine the efficient allocation

To determine the most efficient allocation of apples and bananas between individuals 1 and 2, we must maximize the total utility of both individuals while keeping in mind that all of the apples and bananas must be distributed.

From the constraint equation:

A1 + A2 = 100

B1 + B2 = 150

Now, let's write out the total utility function:

U = U1 + U2

U = 2A1 + B1 + 2A2 + B2 + 2A2B2

Using the Lagrangian method:

L = 2A1 + B1 + 2A2 + B2 + 2A2B2 - λ1(A1 + A2 - 100) - λ2(B1 + B2 - 150)

Taking the partial derivative of L with respect to each variable and equating them to zero, we get:

∂L/∂A1 = 2 - λ1 = 0

∂L/∂A2 = 2 + 4B2 - λ1 = 0

∂L/∂B1 = 1 - λ2 = 0

∂L/∂B2 = 1 + 2A2 - λ2 + 4A2B2 = 0

∂L/∂λ1 = A1 + A2 - 100 = 0

∂L/∂λ2 = B1 + B2 - 150 = 0

Solving these equations, we get:

λ1 = 2, λ2 = 1, A1 = 60, A2 = 40, B1 = 75, B2 = 75

Therefore, the efficient allocation of apples and bananas between individuals 1 and 2 is as follows:

Individual 1 gets 60 apples and 75 bananas

Individual 2 gets 40 apples and 75 bananas

This allocation maximizes the total utility of both individuals subject to the constraint that all the apples and bananas are distributed.
