Answer:
x = 9.7
Step-by-step explanation:
tan θ = opposite side / adjacent side
tan 37° = x / 13
multiply 13 on each side
13 × tan 37° = 13 × x /13
13 × tan 37° = x
Rewrite
x = 13 × tan 37°
multiply, we get
x = 13 × 0.75355..
x = 9.79620265
Round nearest tenth = 9.7

Which expression should you simplify to find the 90% confidence interval, given a sample of 90 people with a sample proportion of 0.25? O A. 0.25 +90 0.25(1-0.25) 1.645 OB. 0.25 + 1.645-0.25 90 O C. 0.25 +1.645 0.25(1-0.25) 90 O D. 0.25 +1.645. V0.25(1–0.25) 90 SUBMIT
Answer:
Option c:
[tex]0.25 \pm 1.645\sqrt{\frac{0.25*(1-0.25)}{90}}[/tex]
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
For this problem, we have that:
You have access to first year enrolment records and you decide to randomly sample 119 of those records. You find that 89 of those sampled went on to complete their degree. This means that [tex]n = 119, \pi = \frac{89}{119} = 0.7478[/tex].
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
Sample of 90 people with a sample proportion of 0.25
This means that [tex]n = 90, p = 0.25[/tex].
Confidence interval:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.25 \pm 1.645\sqrt{\frac{0.25*(1-0.25)}{90}}[/tex]
Which is option c.

Suppose that the speeds of cars travelling on California freeways are normally distributed with a mean of miles/hour. The highway patrol's policy is to issue tickets for cars with speeds exceeding miles/hour. The records show that exactly of the speeds exceed this limit. Find the standard deviation of the speeds of cars travelling on California freeways. Carry your intermediate computations to at least four decimal places. Round your answer to at least one decimal place.
Answer:
the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour
Step-by-step explanation:
The computation of the standard deviation of the speeds of cars is shown below;
The z score for the top 1% is 2.326
So,
= (75 - 61) ÷ standard deviation = 2.326
Standard deviation is
= 14 ÷ 2.326
= 6.0 miles per hour
Hence, the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour

Terrance rolled a bowling ball 5 feet and 2
inches before it hit a bowling pin. If 1 inch is
equal to 2.54 centimeters, how many centimeters
did the bowling ball roll before hitting the pin?
Answer:
157.48cm
Step-by-step explanation:
5feet 2inches
=(5×12) +2in.
=62in. [ 1ft = 12in.]
= 12in. = 2.54cm
=62in. = (2.54 × 62)
=157.48cm
An object is released from rest at a height of 100 meters above the ground. Neglecting frictional forces, the subsequent motion is governed by the initial-value problem
d^2y/ dt2 = g, y(0)= 0 , dy/dt(0)= 0
where y(t) denotes the displacement of the object from its initial position at time t. Solve this initial-value problem and use your solution to determine the time when the object hits the ground.

Given the equation 5 + x - 12 = x- 7.
Part A. Solve the equation 5 + x - 12 = x - 7. In your final answer, be sure to state the solution and include all of your work.
Part B. Use the values x -4, 0, 5 to prove your solution to the equation 5 + x - 12 F x - 7. In your final answer, include all
of your calculations.
Answer:
Step-by-step explanation:
5 + x - 12 = x- 7 (Add the 5 and -12 to simplify)
x - 7 = x - 7 (notice its the same on both sides of equal sign. Add 7 to both sides)
x = x
solution is all real numbers
Part B
5 - 4 - 12 = -4 - 7
-11 = -11
5 + 0 - 12 = 0 - 7
-7 = -7
5 + 5 - 12 = 5 - 7

The Pitts Barbecue Company makes three kinds of barbecue sauce: Extra Hot, Hot, and Mild. Pitts’ vice president of marketing estimates that the company can sell 8,000 cases of its Extra Hot sauce plus 10 extra cases for every dollar it spends promoting this sauce; 10,000 cases of Hot sauce plus 8 extra cases for every dollar spent promoting this sauce; and 12,000 cases of its Mild sauce plus 5 extra cases for every dollar spent promoting this sauce. Although each barbecue sauce sells for $10 per case, the cost of producing the different types of sauce varies. It costs the company $6 to produce a case of Extra Hot sauce, $5.50 to produce a case of Hot sauce, and $5.25 to produce a case of Mild sauce. The president of the company wants to make sure the company manufactures at least the minimum amounts of each sauce that the marketing vice president thinks the company can sell. A budget of $25,000 total has been approved for promoting these items of which at least $5,000 must be spent advertising each item. How many cases of each type of sauce should be made, and how do you suggest that the company allocate the promotional budget to maximize profits?
a. Formulate an LP model for this problem.
b. Create a spreadsheet model for this problem, and solve it using Solver.
c. What is the optimal solution?
Answer:
Case of Extra hot sauce 8000 cases
Case of Hot Sauce 10000 cases
Case of Mild Sauce 12000 + 2000 = 14000
z´(max) = 143500 $
Step-by-step explanation:
Profit of each product:
sale price $ cost $ Profit $
Case of Extra hot sauce 10 6 4
Case of Hot Sauce 10 5.5 4.5
Case of Mild Sauce 10 5.25 4.75
The President of the company already orders the minimum of each case of sauce as follows:
Case of Extra hot sauce 8000
Case of Hot Sauce 10000
Case of Mild Sauce 12000
Let´s call
x₁ quantity of cases of Case of Extra hot sauce over 8000 cases
x₂ quantity of cases of Case of hot sauce over 10000 cases
x₃ quantity of cases of Case of mild sauce over 12000 cases
Then Objective function will be:
z = 4*x₁ + 4.5*x₂ + 4.75*x₃ to maximize
Promoting budget constraint:
each dollar investing in promoting x₁ will become 10*x₁ ( cases)
each dollar investing in promoting x₂ will become 8*x₂(cases )
each dollar investing in promoting x₃ will become 5*x₃ ( cases)
Total investment in promotion is 10000 $ again here we need by sure to invest 5000 $ in promotion for each type of sauce, leaving only extra 10000 $, then:
Constraint due to promotional budge:
10*x₁ + 8*x₂ + 5*x₃ ≤ 10000
General constraints:
x₁ ≥ 0 x₂ ≥0 x₃ ≥ 0 all integers
Then the model is:
z = 4*x₁ + 4.5*x₂ + 4.75*x₃ to maximize
Subject to:
10*x₁ + 8*x₂ + 5*x₃ ≤ 10000
x₁ ≥ 0 x₂ ≥0 x₃ ≥ 0 all integers
After 6 iterations using an on-line solver we got optimal solution:
x₁ = x₂ = 0 x₃ = 2000
z(max) = 9500 $
Then as previous comments, the production will be:
Case of Extra hot sauce 8000 + 0 = 8000
Case of Hot Sauce 10000 + 0 = 10000
Case of Mild Sauce 12000 + 2000 = 14000
The whole profits :
z´ = 4*8000 + 4.5*10000 + 4.75 ( 12000 + 2000)
z´(max) = 32000 + 45000 + 66500
z´(max) = 143500 $
Aditional comments:
If we have n products at the same price it looks obvious that we manufacture the one wich the lowest cost. In this problem, the sales price is the same for the three sauces, and the production cost is the lowest for the Mild sauce, therefore as a consequence, it will be more profitable to manufacture Mild sauce.

f(x) = [x] - 4
f(-3.2) will be ;
Here, we put - 3.2 in place of x as the question is interpreted as the value of f(x) when x = - 3.2
Therefore, we have ;
f(-3.2) = - 3.2 - 4
f(-3.2) = - 7.2
At an effective annual interest rate i, i > 0, each of the following two sets of payments has present value K:
a. A payment of 121 immediately and another payment of 121 at the end of one year
b. A payment of 144 at the end of two years and another payment of 144 at the end of three vears.
Calculate i.
Answer:
Hence the calculated
Step-by-step explanation:
Now,
[tex]121+121v=144v^{2} + 144 v^{3} =K\\121(1+v)=144v^{2} (1+v)\\v^{2} =\frac{121}{144} \\\\v=\frac{11}{12}[/tex]
Then K is calculated as,
[tex]K=121(1+v)\\K=121(1+\frac{11}{12} )\\K=\frac{121(23)}{12} \\\\K= 231.916[/tex]
Here we get,
[tex]i=\left | \left ( \frac{v-1}{v} \right ) \right |\\i=\left | \frac{\frac{11}{12}-1}{\frac{11}{12}} \right |\\i=\frac{1}{11}[/tex]

The elective courses for next year are gym, shop, art, consumer science, criminal justice, and computer science. Amber needs to choose 3 electives. How many ways can she choose her electives
Answer:
She can choose her electives in 20 ways.
Step-by-step explanation:
The order in which she chooses the courses is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
How many ways can she choose her electives?
3 electives from a set of 6. So
[tex]C_{6,3} = \frac{6!}{3!(6-3)!} = 20[/tex]
She can choose her electives in 20 ways.
