Employees in the marketing department of a large regional restaurant chain are researching the amount of money that households in the region spend in restaurants annually. The employees are looking at how the amount spent annually in restaurants by households led by people ages 25 to 34 compares to households led by people ages 45 to 54. To conduct the research, the employees randomly select 12 households in the region led by people ages 25 to 34 and 12 households in the region led by people ages 45 to 54. Each household is asked how much was spent in restaurants during the previous 12 months. The amounts spent for each household, in dollars, are provided in the samples below. One household in each group spent $1,851 in restaurants during the previous 12 months. Calculate the z-score for the household that spent $1,851 for each group. Use a TI-83, TI-83 plus, and TI-84 calculator.

Answer:
The z-score for the group "25 to 34" is 0.37 and the z-score for the group "45 to 54" is 0.25.
Step-by-step explanation:
The data provided is as follows:
25 to 34 45 to 54
1329 2268
1906 1965
2426 1149

Compute the mean and standard deviation for the group "25 to 34" as follows:
[tex]\bar x=\frac{1}{n}\sum x=\frac{1}{8}\times [1329+1906+...+1454]=\frac{13631}{8}=1703.875\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{8-1}\times 1086710.875}=394.01[/tex]
Compute the z-score for the group "25 to 34" as follows:
[tex]z=\frac{x-\bar x}{s}=\frac{1851-1703.875}{394.01}=0.3734\approx 0.37[/tex]
Compute the mean and standard deviation for the group "45 to 54" as follows:
[tex]\bar x=\frac{1}{n}\sum x=\frac{1}{8}\times [2268+1965+...+2158]=\frac{14031}{8}=1753.875\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{8-1}\times 1028888.875}=383.39[/tex]
Compute the z-score for the group "45 to 54" as follows:
[tex]z=\frac{x-\bar x}{s}=\frac{1851-1753.875}{383.39}=0.25333\approx 0.25[/tex]
Thus, the z-score for the group "25 to 34" is 0.37 and the z-score for the group "45 to 54" is 0.25.
The most a baker can spend on strawberries is $95.00. Strawberries cost $3.99 per pound, and the produce supplier charges a $15.20 delivery fee. The following inequality, where s stands for the number of pounds of strawberries, represents this situation:
Answer:
3.99s + 15.20 = 95.00
Step-by-step explanation:
you would put 's' next to the 3.99 because that's what your multiplying or having more than 1 of, then you would add the 15.20 because it's just a one time delivery fee.
Answer:
The answer is 20
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.

The Graduate Management Admission Test (GMAT) is taken by individuals interested in pursuing graduate management education. GMAT scores are used as part of the admissions process for more than 6100 graduate management programs worldwide. The mean sore for all test‑takers is 550 with a standard deviation of 120. A researcher in the Philippines is concerned about the performance of undergraduates in the Philippines on the GMAT. She believes that the mean scores for this year's college seniors in the Philippines who are interested in pursuing graduate management education will be less than 550. She has a random sample of 250 college seniors in the Philippines interested in pursuing graduate management education who plan to take the GMAT. Suppose we know that GMAT scores are Normally distributed with standard deviation σ=120. The null and alternative hypotheses are H0:µ=550 versus Ha:µ<550.
Required:
State the null and alternative hypotheses for the study of the performance on the GMAT of college seniors in the Philippines.
Answer:
H₀: μ = 550 vs. Hₐ: μ < 550.
Step-by-step explanation:
A researcher believes that the mean scores for this year's college seniors in the Philippines who are interested in pursuing graduate management education will be less than 550.
The mean sore for all test‑takers is μ = 550 with a standard deviation of σ = 120.
A random sample of n = 250 college seniors in the Philippines interested in pursuing graduate management education who plan to take the GMAT were selected.
The null and alternative hypotheses for the study of the performance on the GMAT of college seniors in the Philippines is as follows:
H₀: The mean scores for this year's college seniors in the Philippines who are interested in pursuing graduate management education will not be less than 550, i.e. μ = 550.
Hₐ: The mean scores for this year's college seniors in the Philippines who are interested in pursuing graduate management education will be less than 550, i.e. μ < 550.

1. If a 10% increase in price leads to a 40% decrease in quantity demanded, what is the value of price
elasticity of demand? show your work
Answer:
-30
Step-by-step explanation:
10 - 30 is not possible they owe
The value of price elasticity of demand is -4.
The price elasticity of demand refers to how a particular good responds as a result of a change in the price. In this case, the price elasticity of demand is calculated as:
= Percentage change in quantity/ Percentage change in price.
Since a 10% increase in price leads to a 40% decrease in quantity demanded, the price elasticity will be:
= - 40% / 10%
= -4.

Step-by-step explanation:
A study reported that about half of young adults continue to text and drive, despite the dangers. To find out if this
applies to teens, you asked an SRS of 30 classmates if they texted while driving, and 13 responded "Yes."
To see if this result is surprising, you need to conduct a simulation to estimate the probability of obtaining a sample
result as low as yours.
Using the following line of random numbers, where even = Yes and odd = No, how many "Yes" responses are there if
this is the first trial of your simulation? Note: O is considered an even number.

Please help as soon as possible
Answer:
a. When you have two parallel lines cut by a transversal, angles 4 and 6 become same side interior angles, meaning they add to 180 degrees. Alex's mistake is that he thought angles 4 and 6 were corresponding angles, which are equal to each other (corresponding angles would be like angles 2 and 6. they are in the same place in relation to the transversal and the parallel lines. if you moved line l down, angle 2 would be on the same spot as angle 6, so they are corresponding angles).
b. angles 4 = 140 degrees
Step-by-step explanation:
a. Alex thought that angles 6 and 4 were corresponding angles, however, they are same side interior angles. Because two parallel lines are cut by a transversal, we can conclude that angles 4 and 6 are same side interior angles.
Same side interior angles are angles that add to 180, so you would do 180-40 to get angle 4. the measure of angle 4 would be 140 degrees (the answer to b).
describe the translation from the red figure to the blue figure
Answer:
Step-by-step explanation:
From the figure attached,
Coordinates of point A → (2, 3)
Coordinates of point A' → (-3, 1)
Figure shows the translation of point A to point A'.
Relation → A(2, 3) → A'(-3, 1)
→ A'[(2 - 5), (3 - 2)]
Therefore, rule followed for the translation was,
(x, y) → [(x- 5), (y - 2)]

If an individual is selected at random, what is the probability that he or she has a birthday in July? Ignore leap years.
The probability is [tex]\frac{31}{365}[/tex] , If an individual is selected at random have birthday in July .
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]
According to the question
Total number of days in year = 365
Total number of days in a leap year = 366
As, given Ignore leap years
So, we will take days of years as 365 .
Now,
he or she has a birthday in July
i.e ,
It can be be happen any day of July
Total days in July = 31
Now,
Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]
substituting the value
Probability(Event) = [tex]\frac{Total\\\ day\\\ in\\\ July }{Total\\\ days\\\ in\\\ year}[/tex]
Probability(Event) = [tex]\frac{31}{365}[/tex]
Hence, If an individual is selected at random the probability have birthday in July is [tex]\frac{31}{365}[/tex] .

Step 2: x = 36 + 12
Step 3: x = 24
Which statement best explains why Step 2 is incorrect in Skyler's solution?
Answer:
Step 2 is incorrect.
Step-by-step explanation:
It's incorrect because I'm pretty you need to do inverse operation. To get 24 you must subtract, not add.
