The minimum sample size that should be taken to be 90% confident that the sample mean is within 17 emails of the true population mean is 82.

To find the minimum sample size required to estimate a population mean with a given confidence level, we need to use the following formula:

n = (Z * σ / E)^2

where:
- n is the sample size
- Z is the Z-score corresponding to the desired confidence level (90% in this case)
- σ is the population standard deviation (94 emails)
- E is the margin of error (17 emails)

First, find the Z-score for a 90% confidence level. You can do this by checking a Z-table or using a calculator. For a 90% confidence level, the Z-score is approximately 1.645.

Now, plug the values into the formula:

n = (1.645 * 94 / 17)^2
n ≈ (153.63 / 17)^2
n ≈ 9.036^2
n ≈ 81.65

Since we cannot have a fraction of a person, round up to the nearest whole number. Therefore, the minimum sample size that should be taken to be 90% confident that the sample mean is within 17 emails of the true population mean is 82.

Answer: A. 10.2

Step-by-step explanation: For this problem we have to create a second right triangle to find the length. You can apply the pythagorean theorem which continues to 10^2+2^2=c^2 which would get us 104. Then find the root of 104 which is equal to 10.2

That kx^2 > 0 for x > 0, so we have 1+(k+1)x+kx^2 > 1+(k+1)x. Therefore, (1+x)^(k+1) > 1+(k+1)x, and the result follows by mathematical induction.

(a) To study the variations of f(x) = r - ln(1+x), we need to find the derivative of f(x) and analyze its sign.

The derivative is f'(x) = -1/(1+x), which is negative for all x > 0.

Therefore, f(x) is a decreasing function on (0, ∞).

Also, lim x→0 f(x) = r > -∞, and lim x→∞ f(x) = -∞.

Therefore, f(x) has a maximum at x = 0, which is r.

(b) To study the variations of g(x) = (1 + x) ln(1 + x) - 2, we need to find the derivative of g(x) and analyze its sign.

The derivative is g'(x) = ln(1 + x), which is positive for all x > -1.

Therefore, g(x) is an increasing function on (-1, ∞). Also, lim x→-1+ g(x) = -∞, and lim x→∞ g(x) = ∞.

Therefore, g(x) has a minimum at some point in (-1, ∞).

(c) To conclude that for all positive integer n, we have (1+x)^n > 1+nx, we can use mathematical induction.

For n = 1, we have (1+x)^1 = 1+x > 1+1x. Assume that (1+x)^k > 1+kx for some positive integer k. Then, for n = k+1, we have (1+x)^(k+1) = (1+x)^k * (1+x) > (1+kx) * (1+x) = 1+(k+1)x+kx^2.

Note that kx^2 > 0 for x > 0, so we have 1+(k+1)x+kx^2 > 1+(k+1)x. Therefore, (1+x)^(k+1) > 1+(k+1)x, and the result follows by mathematical induction.

The three complex cube roots of z^3 are:

z_1 = 2^(1/3) [cos(π/9) + i sin(π/9)]

z_2 = 2^(1/3) [cos(5π/9) + i sin(5π/9)]

z_3 = 2^(1/3) [cos(7π/9) + i sin(7π/9)]

First, we can find the modulus of the complex number as |z^3| = |√3+i√5| = √(3+5) = 2. We can also find the argument of the complex number as arg(z^3) = arctan(√5/√3) = π/3 - arctan(√3/√5).

Now, we can express the complex number in polar form as z^3 = 2(cosθ + i sinθ), where θ = π/3 - arctan(√3/√5).

Using De Moivre's theorem, we can find the cube roots of z as:

z_1 = 2^(1/3) [cos(θ/3) + i sin(θ/3)]

z_2 = 2^(1/3) [cos((θ+2π)/3) + i sin((θ+2π)/3)]

z_3 = 2^(1/3) [cos((θ+4π)/3) + i sin((θ+4π)/3)]

Simplifying further, we get:

z_1 = 2^(1/3) [cos(π/9) + i sin(π/9)]

z_2 = 2^(1/3) [cos(5π/9) + i sin(5π/9)]

z_3 = 2^(1/3) [cos(7π/9) + i sin(7π/9)]

The gardener used 61.5 gallons of gasoline in his lawn mowers in the one month.

Let's call the amount of gasoline used in the lawn mowers "x".

We know that the total amount of gasoline used is 61.5 gallons, so:

x + (the amount used for other things) = 61.5

We don't know how much was used for other things, but we do know that "of the total amount of gasoline" used, a certain percentage was used in the lawn mowers. Let's call that percentage "p".

"Of" means "times", so we can write:

p * 61.5 = x

Now we have two equations:

x + (the amount used for other things) = 61.5

p * 61.5 = x

We want to solve for x, so let's isolate it in the second equation:

p * 61.5 = x

x = p * 61.5

Now we can substitute that into the first equation:

p * 61.5 + (the amount used for other things) = 61.5

Simplifying:

p * 61.5 = 61.5 - (the amount used for other things)

p = (61.5 - the amount used for other things) / 61.5

We don't know the exact amount used for other things, but we do know that it's less than or equal to 61.5, so:

p = (61.5 - something) / 61.5

p = (61.5 - 0) / 61.5

p = 1

So all of the gasoline was used in the lawn mowers, and:

x = 1 * 61.5

The probability that the airline will lose at least 10 suitcases in a week is 0.1723 or about 17.23%.

Given information:

µ = 6.7 (mean)

σ = 3.5 (standard deviation)

We need to find the probability of losing at least 10 suitcases in a week. We can use the normal distribution formula to solve this problem:

P(X ≥ 10) = 1 - P(X < 10)

To use this formula, we need to standardize the variable X to the standard normal distribution with mean 0 and standard deviation 1. We can do this using the following formula:

Z = (X - µ) / σ

Substituting the given values, we get:

Z = (10 - 6.7) / 3.5

Z = 0.943

Now, we can use a standard normal distribution table or calculator to find the probability of Z being greater than or equal to 0.943. The table or calculator will give us the probability of Z being less than 0.943, which we can then subtract from 1 to get the desired probability.

Using a standard normal distribution table, we find that P(Z < 0.943) = 0.8277.

Therefore, P(X ≥ 10) = 1 - P(X < 10) = 1 - P(Z < 0.943) = 1 - 0.8277 = 0.1723.

So, the probability that the airline will lose at least 10 suitcases in a week is 0.1723 or about 17.23%.

To find the parametric equations for the line of intersection of the given planes, we first need to solve the system of equations:

1. x + 2y + z = 1
2. 2x + 5y + 32 = 4

Step 1: Solve for x from equation 1:
x = 1 - 2y - z

Step 2: Substitute x in equation 2 with the expression found in step 1:
2(1 - 2y - z) + 5y + 32 = 4

Now we can use elimination to solve for one variable. Let's eliminate y by multiplying the first equation by 5 and subtracting it from the second equation:

Step 3: Simplify and solve for y:
2 - 4y - 2z + 5y + 32 = 4
y - 2z = -30

Step 4: Designate z as the parameter t:
z = t

Step 5: Substitute z with t in the expression for y:
y = 2t - 30

Step 6: Substitute z with t in the expression for x:
x = 1 - 2(2t - 30) - t
x = 1 - 4t + 60 - t
x = 61 - 5t

Answer:

Sure, let's break down each part step by step.

Part A:

To calculate how much fabric is needed to make 3 aprons, we need to multiply the amount of fabric needed for one apron by 3.1 apron requires

1 1/2 yards of fabric for the front and 1/8 yards of fabric for the tie.1 1/2 yards + 1/8 yards = 15/8 yards (Adding fractions with a common denominator)

Now we can multiply the total fabric needed for one apron by 3 to get the fabric needed for 3 aprons:

3 * 15/8 yards = 45/8 yards (Multiplying by a whole number)

So, the total fabric needed to make 3 aprons is 45/8 yards.

Part B:

If Susan originally has 7 yards of fabric and she uses 45/8 yards to make 3 aprons, we can subtract the amount used from the original amount to find out how much fabric is left over.

7 yards - 45/8 yards = 56/8 yards - 45/8 yards (Subtracting fractions with a common denominator)

= 11/8 yards (Subtracting fractions)

So, after making the aprons, Susan will have 11/8 yards of fabric left over.

Part C:

To determine if Susan has enough fabric left to make another apron, we need to compare the amount of fabric left (11/8 yards) with the amount of fabric needed for one apron (1 1/2 yards + 1/8 yards = 15/8 yards).

Since 15/8 yards is greater than 11/8 yards, Susan does not have enough fabric left to make another apron. She is short by 4/8 yards (or 1/2 yard) of fabric.

1. Let Z be a standard, normally distributed random variable.
a. P(Z ≤ 2.32)
To find this probability, you need to use the standard normal distribution table (also known as the Z-table) to look up the value corresponding to Z = 2.32. The value you find in the table is the probability P(Z ≤ 2.32).
b. P(Z ≥ -1.56)
To find this probability, first look up the value corresponding to Z = -1.56 in the standard normal distribution table. This value represents P(Z ≤ -1.56). Since we want P(Z ≥ -1.56), we need to find the complement, which is 1 - P(Z ≤ -1.56).
c. P(-1.43 ≤ Z ≤ 2.47)
To find this probability, look up the values corresponding to Z = -1.43 and Z = 2.47 in the standard normal distribution table. The difference between these two values will give you the probability P(-1.43 ≤ Z ≤ 2.47).
d. Find z* so that P(-z* ≤ Z ≤ z*) = 0.99
To find the z* value, you need to look up the value in the standard normal distribution table that corresponds to the area of 0.995 (since 0.99 is the area between -z* and z*, and each tail contains 0.005). Once you find the value in the table, look at the corresponding Z value. This value will be your z*.

The probability that a wedding costs less than $20,000 is approximately 0.3745.

The probability that a wedding costs between $20,000 and $31,000 is approximately 0.6188.

The minimum cost for a wedding to be included among the most expensive 5% of weddings is approximately $31,229.

(a) To find the probability that a wedding costs less than $20,000, we need to standardize the value of $20,000 by subtracting the mean and dividing by the standard deviation:

z = (20000 - 21858) / 5800 = -0.32

We can then use a standard normal distribution table or technology to find the corresponding probability:

P(z < -0.32) ≈ 0.3745

Therefore, the probability that a wedding costs less than $20,000 is approximately 0.3745.

(b) To find the probability that a wedding costs between $20,000 and $31,000, we need to standardize both values and find the area between the corresponding z-scores:

z1 = (20000 - 21858) / 5800 = -0.32

z2 = (31000 - 21858) / 5800 = 1.58

Using a standard normal distribution table or technology, we can find the probabilities:

P(-0.32 < z < 1.58) ≈ 0.6188

Therefore, the probability that a wedding costs between $20,000 and $31,000 is approximately 0.6188.

(c) To find the minimum cost for a wedding to be included among the most expensive 5% of weddings, we need to find the z-score that corresponds to the 95th percentile of the standard normal distribution. We can use a standard normal distribution table or technology to find this value:

z = invNorm(0.95) ≈ 1.645

We can then use the formula for standardizing a value to find the minimum cost:

z = (x - 21858) / 5800

Solving for x, we get:

x = z(5800) + 21858

x = 1.645(5800) + 21858

x ≈ 31229

Therefore, the minimum cost for a wedding to be included among the most expensive 5% of weddings is approximately $31,229.
