ANSWER:
850customers were served in the third week.
Explanation:
First week = 730 customers
Second week = 696 customers
Difference between the first and second week = 730 - 696
= 34
4/100 x (customers served in the third week) = 34
4 x customers served in the third week = 34 x 100
4 x customers served in the third week = 3400
customers served in the third week = 3400/4
customers served in the third week = 850

Explanation:
This data set shows the ages of the last 12 winners of a
prestigious film award for Actress in a Leading Role.
61, 32, 33, 45, 29, 62, 22, 44, 54, 26, 28, 60
Calculate the statistics of mean and standard deviation
of the data set. Round to the nearest hundredth, if
necessary.
O mean 38.50 and standard deviation - 14.89
O mean 38.50 and standard deviation = 40
O mean = 41.33 and standard deviation = 40
mean 41.33 and standard deviation - 14.89
Answer:
D. mean is 41.33, and standard deviation is 14.89
Explanation:
Given the data set: 61, 32, 33, 45, 29, 62, 22, 44, 54, 26, 28, 60 of 12 winners.
i. The mean of the data set = [tex]\frac{sum of data set}{number of data set}[/tex]
= [tex]\frac{61 + 32 + 33 + 45 + 29 + 62 + 22 + 44 + 54 + 26 + 28 + 60}{12}[/tex]
= [tex]\frac{496}{12}[/tex]
= 41.3333
The mean of the data set = 41.33
ii. Standard deviation = [tex]\sqrt{\frac{Sum(x_{i} - U) ^{2} }{N} }[/tex]
Where: [tex]x_{i}[/tex] is the value of each data set given, U is the mean, N is the number of data set.
Sum ([tex]x_{i}[/tex] - U) = [tex](61 - 41.33)^{2}[/tex] + [tex](32 - 41.33)^{2}[/tex] + [tex](33 - 41.33)^{2}[/tex] + [tex](45 - 41.33)^{2}[/tex] + [tex](29 - 41.33)^{2}[/tex] + [tex](62 - 41.33)^{2}[/tex] + [tex](22 - 41.33)^{2}[/tex] + [tex](44 - 41.33)^{2}[/tex] + [tex](54 - 41.33)^{2}[/tex] + [tex](26 - 41.33)^{2}[/tex] + [tex](28 -41.33)^{2}[/tex] + [tex](60 - 41.33)^{2}[/tex]
= 386.91 + 87.05 + 69.39 + 13.47 + 152.03 + 427.25 + 373.65 + 7.13 + 160.53 + 235.01 + 177.69 + 348.57
= 2438.68
Standard deviation = [tex]\sqrt{\frac{2438.68}{12} }[/tex]
= 14.26
Therefore, the statistics mean is 41.33 and standard deviation is 14.89

A population of values has a normal distribution with μ = 21.9 μ = 21.9 and σ = 47.4 σ = 47.4 . You intend to draw a random sample of size n = 96 n = 96 . Find the probability that a single randomly selected value is between 12.7 and 20.4. P(12.7 < X < 20.4) = Find the probability that a sample of size n = 96 n = 96 is randomly selected with a mean between 12.7 and 20.4. P(12.7 < M < 20.4) = Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

In which type of US election is it possible for the winning candidate to get fewer popular votes than the opposing candidate
A. most state government elections
B. House elections
C. Senate elections
D. most local government elections
E. presidential elections
Answer:
The correct answer is E)Presidential elections.
The presidential election is not determined by popular vote. Rather, it is determined by a system known as the electoral college. The electoral college system involves each state having a certain number of electoral votes roughly based on their population size. In this system, states with larger populations have more electoral votes.
In the electoral college, a candidate must receive 270 electoral votes in order to become president. If a candidate reaches this threshold they win, regardless of the popular vote results.
All of the other elections mentioned in the answer choices are determined by popular vote.
Explanation:
Answer: Presidential Elections
Explanation:
Heather had a pot filled with salt water. She could not see the salt inside the water, but she could taste that the water was salty. Heather heated the pot using a stovetop until all of the water evaporated. The bottom of the pot was covered with white salt crystals, but the water had all turned into water vapor that Heather could not see. Which of these is true about the salt left in the pot after the water evaporated? A. The salt is made of the same particles as it was before the water evaporated. B. The salt is not made of particles because it was invisible when it was dissolved in water. C. The salt particles absorbed the water particles as the water changed into a gas. D. The salt is now made of particles, but it was not made of particles when it was dissolved.
Answer:
A the salt is made of the same particles
Determine the area under the standard normal curve that lies to the left (a) Z= 1.34, (b) The area to the left of 2 = – 0.25 is (Round to four decimal places as needed.) (c) The area to the left of Z = 1.66 is 0.949 (Round to four decimal places as needed.)
The areas under the standard normal curve is determined as follows:
(a) Using a standard normal distribution table, the area to the left of Z = 1.34 is 0.9099. (to four decimal places)
(b) Using a standard normal distribution table, the area to the left of Z = -0.25 is 0.4013 (to four decimal places)
(c) Using a standard normal distribution table, the area to the left of Z = 1.66 is 0.9515 (to four decimal places).
What does Area under the Standard Normal Curve mean and why is it important?The area under the standard normal curve represents the probability of a standard normal variable taking a value within a certain range.
It is important because it allows us to calculate probabilities and make statistical inferences using the standard normal distribution, which is a fundamental concept in statistical analysis. It is also used in many fields such as finance, engineering, and social sciences to model and analyze data.
One real-life application of the standard normal curve is in finance, where it is used to model stock prices and calculate the probabilities of different investment outcomes.
