A contractor has submitted bids on three state jobs: an office building, a theater, and a parking garage. State rules do not allow a contractor to be offered more than one of these jobs. If this contractor is awarded any of these jobs, the profits earned from these contracts are: 13 million from the office building, 9 million from the theater, and 4 million from the parking garage. His profit is zero if he gets no contract. The contractor estimates that the probabilities of getting the office building contract, the theater contract, the parking garage contract, or nothing are .17, .27, .45, and .11, respectively. Let x be the random variable that represents the contractor's profits in millions of dollars. Write the probability distribution of x. Find the mean and standard deviation of x.

Answers

Answer 1

Answer:

Probability distribution:

x (million) P(x)

13 0.17

9 0.27

4 0.45

0 0.11

Mean: 6.44

Standard deviation: 4.04

Explanation:

The probability distribution is a table that shows the profits earned and its respective probabilities, so:

x (million) P(x)

13 0.17

9 0.27

4 0.45

0 0.11

Then, the mean can be calculated as the sum of each profit multiplied by its respective probability. Therefore, the mean E(x) is equal to:

E(x) = 13(0.17) + 9(0.27) + 4(0.45) + 0(0.11)

E(x) = 2.21 + 2.43 + 1.8 + 0

E(x) = 6.44

Finally, to calculate the standard deviation, we first need to find the differences between each value and the mean, and then find the square of these values, so:

x x - E(x) (x - E(x))²

13 13 - 6.44 = 6.56 (6.56)² = 43.03

9 9 - 6.44 = 2.56 (2.56)² = 6.55

4 4 - 6.44 = -2.44 (-2.44)² = 5.95

0 0 - 6.44 = -6.44 (-6.44)² = 41.47

Then, the standard deviation will be the square root of the sum of the values in the last column multiply by each probability:

[tex]\begin{gathered} s=\sqrt[]{43.03(0.17)+6.55(0.27)+5.95(0.45)+41.47(0.11)} \\ s=\sqrt[]{16.3264} \\ s=4.04 \end{gathered}[/tex]

Therefore, the answers are:

Probability distribution:

x (million) P(x)

13 0.17

9 0.27

4 0.45

0 0.11

Mean: 6.44

Standard deviation: 4.04

I need help with homework . BC=5, angle A=25 degree.

Answers

AC = 2.332

AB = 5.517

Explanation:

Given:

BC = 5.

Angle B = 25 degree.

Angle C = 90 degree.

The objective is to find AC and AB.

By the trigonometric functions, Consider AB as hypotenuse, AC as opposite and BC as adjacent.

Then, the relationship between opposite (AC) and adjacent (BC) cnbe calculated by trigonometric ratio of tan theta.

[tex]\begin{gathered} \tan \theta=\frac{opposite}{adjacent} \\ \tan 25^0=\frac{AC}{5} \\ AC=\tan 25^0\cdot5 \\ AC=2.332 \end{gathered}[/tex]

Now, the length AB can be calculated by Pythagorean theorem,

[tex]\begin{gathered} AB^2=AC^2+BC^2 \\ AB^2=2.332^2+5^2 \\ AB^2=5.436+25 \\ AB^2=30.436 \\ AB=\sqrt[]{30.436} \\ AB=5.517 \end{gathered}[/tex]

Let's check the value using trigonometric ratios.

For the relationship of opposite and hypotenuse use sin theta.

[tex]\begin{gathered} \sin \theta=\frac{opposite}{hypotenuse} \\ \sin 25^0=\frac{2.332}{y} \\ y=\frac{2.332}{\sin 25^0} \\ y=5.517 \end{gathered}[/tex]

Thus both the answers are matched.

Hence, the length of the side AC = 2.332 and the length of the side AB = 5.517.

? Question
Rachel and Jeffery are both opening savings accounts. Rachel deposits $1,500 in a savings account that earns 1.5% interest,
compounded annually. Jeffery deposits $1,200 in a savings account that earns 1% interest per year, compounded
continuously.
If y represents the account balance after t years, which two equations form the system that best models this situation?

Answers

For the conditions stated, y=1500+2250t and y=1200+1200t, respectively, will be necessary equations because both Rachel and Jeffery are opening savings accounts. Rachel places $1,500 in a savings account that accrues annual compound interest of 1.5%. Jeffery places $1,200 in a savings account that accrues continuously compounded interest of 1% per year.

What is equation?

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Here,

according to given condition,

y=1500+1500*1.5t

y=1500+2250t

y=1200+1200*1t

y=1200+1200t

So the required equation will be y=1500+2250t and y=1200+1200t for the conditions given as Rachel and Jeffery are both opening savings accounts. Rachel deposits $1,500 in a savings account that earns 1.5% interest, compounded annually. Jeffery deposits $1,200 in a savings account that earns 1% interest per year, compounded continuously.

Find the probability that a randomly selected person with a kidney stone will take longer than 17 days to pass it. 0.2Incorrectc. Find the minimum number for the upper quarter of the time to pass a kidney stone. 0.8Incorrect days.

Answers

Answer:

• (a)X ~ N(16, 5)

,

• (b)0.4207

,

• (c)19.37 days

Explanation:

(a)

• The mean amount of time = 16 days

,

• The standard deviation = 5 days.

Therefore, the distribution of X is:

[tex]X\sim N(16,5)[/tex]

(b)P(X>17)

To find the required probabability, recall the z-score formula:

[tex]z=\frac{X-\mu}{\sigma}[/tex]

When X=17

[tex]z=\frac{17-16}{5}=\frac{1}{5}=0.2[/tex]

Next, find the probability, P(x>0.2) from the z-score table:

[tex]P(x>0.2)=0.4207[/tex]

The probability that a randomly selected person with a kidney stone will take longer than 17 days to pass it is 0.4207.

(c)The upper quarter is the value under which 75% of data points are found.

The z-score associated with the 75th percentile = 0.674.

We want to find the value of X when z=0.674.

[tex]\begin{gathered} z=\frac{X-\mu}{\sigma} \\ 0.674=\frac{X-16}{5} \\ \text{ Cross multiply} \\ X-16=5\times0.674 \\ X=16+(5\times0.674) \\ X=19.37 \end{gathered}[/tex]

The minimum number for the upper quarter of the time to pass a kidney stone is 19.37 days.

The probability of getting exactly 1 blue marble from a bag which is  filled with 5 blue and 4 red marbles is 40/81.

What is probability?

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

A bag is filled with 5 blue and 4 red marbles.

The total number of marble in the bag are,

5+4=9

One marble is taken at random from the bag, the color is noted and then it is replaced. The probability of getting blue marble is,

P(B)=5/9

probability of getting red marble is,

P(R)=4/9

The Probability of getting red marble in first pick and  probability of getting blue marble in second pick

P1=5/9×4/9=20/81

The Probability of getting blue marble in first pick and probability of getting red marble in second pick is,

p2=4/9×5/9=20/81

The exactly 1 blue is taken out, when first marble is red and second is blue or the first one is blue and second one is red. Thus, the probability of getting exactly 1 blue is,

P=p1+p2

=20/81+20/81

Answers

Answer:

  we can use two ways to write 180° along with the inscribed angle theorem to obtain the desired relation

Step-by-step explanation:

Given ∆ABC inscribed in a circle O where E is the midpoint of arc BC and ED is a diameter, you want to prove ∠DEA = 1/2(∠B -∠C).

Setup

We can add add arcs to make 180° in two different ways, then equate the sums.

  arc EB +arc BA +arc AD = 180°

  arc EC +arc CA -arc AD = 180°

Equating these expressions for 180°, we have ...

  arc EB +arc BA +arc AD = arc EC +arc CA -arc AD

Solution

Recognizing that arc EB = arc EC, we can subtract (arc EB +arc BA -arc AD) from both sides to get ...

  2·arc AD = arc CA -arc BA

The inscribed angle theorem tells us ...

arc AD = 2∠DEAarc CA = 2∠Barc BA = 2∠C

Making these substitutions into the above equation, we have ...

  4∠DEA = 2∠B -2∠C

Dividing by 4 gives the relation we're trying to prove:

  ∠DEA = 1/2(∠B -∠C)

Answers

To find the solution we need to graph both lines on the plane. To do this we need to find two points for each line.

First we graph the line y=x+2. To find a point we give x a value, whichever value we like, and then find y.

Let x=0, then:

[tex]\begin{gathered} y=0+2 \\ y=2 \end{gathered}[/tex]

Then we have the point (0,2).

Let x=1, then:

[tex]\begin{gathered} y=1+2 \\ y=3 \end{gathered}[/tex]

Then we have the point (1,3).

Then we plot this points in the plane and join them with a line:

Now let's plot eh second line, y=3x-4.

Let x=0, then:

[tex]\begin{gathered} y=3(0)-4 \\ y=-4 \end{gathered}[/tex]

So we have the points (0,-4).

Let x=1, then:

[tex]\begin{gathered} y=3(1)-4 \\ y=3-4 \\ y=-1 \end{gathered}[/tex]

so we have the point (1,-1).

Now we plot this points and join them with a line:

Once we have both lines graph in the plane the solution is the intersection of the lines. Looking at the graph we conclude that the solution of the system is x=3 and y=5.

Company B charges $30.50 and 9¢ per mile, then for x miles, Company B charges 30.5 + 0.09x dollars

Subtracting the second equation to the first one,

75.5 + 0.14x

-

30.5 + 0.09x

----------------------

45 + 0.05x

For x miles, Company A charges 45 + 0.05x dollars more than Company B.

The graph of f (in blue) is translated a whole number of units horizontally and vertically to obtain the graph of k (in red).The function fis defined by f(x) = fx/.Write down the expression for k(x).

Answers

Solution

We have the original function defined as:

[tex]f(x)=-\sqrt[]{x}[/tex]

And we want to obtain the new red line so then we need to check how many units down and right the function moves:

And we have 3 units to the right and 2 units down then the answer is:

[tex]h(x)=-\sqrt[]{x-3}-2[/tex]

Then the final answer is:

h(x) = -sqrt(x-3) -2

Graph the functions on the same coordinate plane.f(x) = −5g(x) = x^2 + 2x − 8What are the solutions to the equation f(x) = g(x)? Select each correct answer.−5−3−113

ANSWER

[tex]\begin{equation*} -3,1 \end{equation*}[/tex]

EXPLANATION

The graphical solution to the given equation is obtained at the points where the two graphs of the two functions intersect each other on the coordinate plane.

To graph f(x), we simply draw a straight horizontal line at the point y = -5.

To graph g(x), we have to find coordinate points by substituting values of x into the function and obtaining values for g(x).

Let us find the value of g(x) when x = -3, -1, 1:

[tex]\begin{gathered} x=-3: \\ g(-3)=(-3)^2+2(-3)-8=9-6-8 \\ g(-3)=-5 \\ x=-1: \\ g(-1)=(-1)^2+2(-1)-8=1-2-8 \\ g(-1)=-9 \\ x=1: \\ g(1)=(1)^2+2(1)-8=1+2-8 \\ g(1)=-5 \end{gathered}[/tex]

Now, we have three points to plot the graph with: (-3, -5), (-1, -9), (1, -5)

Let us now plot the graphs of the functions:

Therefore, the solutions to the equation f(x) = g(x) are:

[tex]\begin{gathered} x=-3,x=1 \\ \Rightarrow-3,1 \end{gathered}[/tex]

Need help ASAP Which graph shows the asymptotes of the function f(x)= 4x-8 _____ 2x+3

Answers

First we will calculate the vertical asymptote, is when the denominator of the function given is equal to zero

[tex]\begin{gathered} 2x+3=0 \\ x=-\frac{3}{2} \end{gathered}[/tex]

then we will calculate the horizontal asymptote because the degree of the numerator and the denominator is equal we can calculate the horizontal asymptote with the next operation

[tex]y=\frac{a}{b}[/tex]

a= the coefficient of the leading term of the numerator

b=the coefficient of the leading term of the denomintor

in our case

a=4

b=2

[tex]y=\frac{4}{2}=2[/tex][tex]y=2[/tex]

As we can see the graph that shown the asymptotes of the function is the graph in the option C.
