The owner of a pizza restaurant in France knows that the time customers spend in the restaurant on Saturday evening has mean 90 minutes and standard deviation 15 minutes. He has read that pleasant odors can influence customers, so he spreads a lavender odor throughout the restaurant. Presented are the times, in minutes, for customers on the next Saturday evening.

Answers

Answer 1

Answer:

hello your question is incomplete attached below is the missing part

Question : What is the value of the test statistic

answer : = 5.73

Step-by-step explanation:

Mean value = 90 minutes

std = 15 minutes

Calculate the test statistic

mean value  of given data = ∑ x / n = 105.7

since the value of standard deviation is given we will assume a normal distribution

Hence we will apply  z test statistics

z = mean value of given data - Mean value / 15 √30

   = ( 105.7 - 90 )  / 15 √30

  = 5.73

Answers

ST is a Straight line, x=108 degrees.

Step-by-step explanation:

Since ST is a straight line, it measures 180 degrees.

This means that:

x+(2/3)x=180

The simplified version is 5x/3=180.

Now, we multiply both sides by 3.

The equation becomes 5x=540;

which is ultimately x=108.

Therefore, ST is a straight line , x=108.

Maximizing yield. Hood Apple Farm harvests an average of 30 bushels of apples per tree when 20 trees are planted on an acre of ground. If 1 more tree is planted per acre, the yield decreases by 1 bushel (bu) per tree as a result of crowding. How many trees should be planted on an acre in order to get the highest yield

Answers

Answer:

In order to get the highest yield, 25 tress should be planted

Step-by-step explanation:

Given the data in the question;

Let n be number bushel, b is bushels per tree, t is number of trees

from the question, if t = 20, b = 30

and if t = 21 then b = 29

so t + b is constant

t + b = 50 ----- let this be equation

now, n = t × b

so b = n / t

hence from equation, we input b = n/t

t + n/t = 50

n/t = 50 - t

n = t(50 - t)

n = 50t - t²

now we get the derivatives

Note, The maximum amount of trees is simply where the derivative is equal zero, so;

0 = 50 - 2t

2t = 50

t = 50/2

t = 25

Therefore, In order to get the highest yield, 25 tress should be planted

A car company is testing how well its cars handle skidding to a complete stop after hitting the brakes while going at different speeds on an asphalt road. The equation represents the car’s speed, in miles/hour, when the brakes are applied as a function of the distance, in feet, the car skids. The table of values represents the function S(D). Use the table of values to calculate the average rate of change between the given intervals. Then interpret what the average rate of change means in this context.

Answer:

D          SD= sqrt(22.5D)   Average Rate of Change

In the context of this problem, the average rate of change is the rate at which the car decelerates as it skids. As the distance that the car skids increases, the rate at which the car decelerates decreases at a gradual rate.
