b. A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected
from its automatic filling process, the amount of cheese inserted into the ravioli is normally distributed. To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli and measure the weight of cheese filling. They find the 99% confidence interval of 14.16 to 15.84 grams. Which of the following is the correct interpretation?
I. We are 99% confident that the mean weight of cheese filling in all ravioli made by this process is between 14.16 and 15.84 grams.
II. 99% of all ravioli made by this process will have cheese filling weights between 14.16 and 15.84 grams.
III.We are 99% confident that the interval (14.16, 15.84) contains the mean weight of cheese filling in all ravioli made by this process.
IV. The weight of cheese filling in the ravioli is between 14.16 and 15.84 grams 99% of the time.
A) I only
B) III only
C)I and III.
D) II and III
E) I and IV
Answers
Answer: a. B) 1.432
b. E) I and IV
Step-by-step explanation:
a. Margin of error to construct a 99% confidence interval is calculated as
\(ME=t.\frac{s}{\sqrt{n}}\)
where
t is the critical value expressed as t-score, which comes from t-distribution;
s is sample standard deviation
n is sample size
In this case, a t-score is used because the population standard deviation is unknown and the sample size is small, n < 30.
The way to find t-score is:
1) Define the degree of freedom, which is sample size minus 1: df = n - 1;
2) Compute alpha: \(\alpha=1-\frac{confidence}{100}\);
3) Find the critical probability: \(p=1-\frac{\alpha}{2}\)
With the df and critical probability, consulte the t-distribution table and find the score.
For the cheese filling:
df = 24
p = 0.995
t-score = 2.797
Calculating margin of error:
\(ME=2.797.\frac{2.56}{\sqrt{5}}\)
ME = 1.432
The margin of error to construct a 99% confidence interval for the true mean amount of cheese filling is 1.432.
b. Confidence interval is an interval in which we have a percentage of certainty that the true population mean is. For example, with a 99% confidence interval of 14.16 to 15.84 grams, we are 99% confident that the true mean weight of cheese filling is between those numbers or that the weight of cheese filling is between 14.16 and 15.84 grams 99% of the time.
The water usage at a car wash is modeled by the equation W(x) = 5x3 + 9x2 − 14x + 9, where W is the amount of water in cubic feet and x is the number of hours the car wash is open. The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The amount of decrease in water used is modeled by D(x) = x3 + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours. Write a function, C(x), to model the water used by the car wash on a shorter day. C(x) = 5x3 + 7x2 − 14x − 6 C(x) = 4x3 + 7x2 − 14x + 6 C(x) = 4x3 + 7x2 − 14x − 6 C(x) = 5x3 + 7x2 − 14x + 6
Answers
W(x) - C(x) = 2(W(x) - C(x))
Solving this equation for C(x), we get:
C(x) = (W(x) - 2W(x))
= W(x)(1 - 2)
= (5x3 + 9x2 - 14x + 9)(1 - 2)
= (5x3 + 7x2 - 14x + 6)
Therefore, the function C(x) to model the water used by the car wash on a shorter day is:
C(x) = (5x3 + 7x2 - 14x + 6)

For this case we can do the following:
\(\frac{1}{\cos\theta}\cdot\frac{\sin\theta}{\cos\theta}-\cos \theta\cdot\frac{\cos\theta}{\sin\theta}=\sin \theta\)\(\frac{\sin\theta}{cos^2\theta}-\frac{\cos^2\theta}{\sin\theta}=\sin \theta\)\(\frac{\sin^2\theta-\cos^2\theta\cos^2\theta}{\sin\theta\cos^2\theta}=\sin \theta\)then we can croos multiply:
\(\sin ^2\theta-\cos ^2\theta\cos ^2\theta=\sin ^2\theta\cos ^2\theta\)then we can redistribute the terms and we got:
\(\sin ^2\theta=\cos ^2\theta\cos ^2\theta+\sin ^2\theta\cos ^2\theta\)taking common factor cos^2 we got:
\(\sin ^2\theta=\cos ^2\theta(\cos ^2\theta+\sin ^2\theta)\)Since:
\(\sin ^2\theta+\cos ^2\theta=1\)We have:
\(\sin ^2\theta=\cos ^2\theta\)And thae answer for this case is:

joan’s finishing time for the bolder boulder 10k race was 1.81 standard deviations faster than the women’s average for her age group. there were 410 women who ran in her age group. assuming a normal distribution, how many women ran faster than joan? (round down your answer to the nearest whole number.)
Answers
Given that Joan's finishing time was 1.81 standard deviations faster than the women's average for her age group, we can use the properties of a normal distribution to find the corresponding percentage.
Since Joan is faster than the average, her finishing time would fall in the top portion of the distribution. Using a standard normal distribution table or a calculator, we can find the percentage of data below her finishing time. The Z-score associated with 1.81 standard deviations is approximately 0.9641, which corresponds to a percentage of 96.41%.
This means that approximately 96.41% of the women in her age group ran slower than Joan. To find the number of women who ran faster, we subtract this percentage from 100%: 100% - 96.41% = 3.59%.
To determine the number of women, we multiply the percentage by the total number of women in her age group: 3.59% * 410 = 14.709.
Rounding down to the nearest whole number, we can conclude that approximately 14 women ran faster than Joan.

The linear model would be a reasonable way to predict the temperature as temperature determines the number of ice cream that would be sold.
What is temperature?Temperature is a unit of hotness and coldness that can be described in terms of any number of arbitrary scales. It also represents the direction wherein heat energy will naturally flow, from either a hotter (i.e., higher temperature) body to a colder body.
Temperature is not the same as the energy of such a thermodynamic system; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a significantly higher temperature. The linear model would be a reasonable way to predict the temperature as temperature determines the number of ice cream that would be sold.

The number of cannonballs in illustration is 506.
What is illustration?Math Illustrations enables you to produce more useful geometry figures for your students in less time by fusing the constraint-based design of Geometry Expressions with simple-to-use sketching and graphing features.
The number of cannonballs in the first layer = 1² = 1
Number of cannonballs in the second layer = 2² = 4
Number of cannonballs in the third layer = 3² = 9
So, the generalized formula to count the balls is given as
= n(n + 1) (2n + 1)/ 6
Here, n= the total number of layers
Put n =11
11(11 + 1)(2(11) + 1) / 6
= 11(12)(23)/6

A website wants to detect if a visitor is a robot or a human. They give the visitor seven CAPTCHA tests that are hard for robots but easy for humans. If the visitor fails any of the tests, they are flagged as a robot. The probability that a human succeeds at a single test is 0.95, while a robot only succeeds with probability 0.3. Assume all tests are independent. The percentage of visitors on this website that are robots is 10%; all other visitors are human. (a) If a visitor is actually a robot, what is the probability they get flagged (the probability they fail at least one test)? -4- (b) If a visitor is actually a human, what is the probability they get flagged (the probability they fail at least one test)? (c) Suppose a visitor gets flagged. What is the probability that the visitor is a robot?
Answers
(a) The probability that a visitor will be flagged (i.e., fail at least one test) is 0.957 if they are genuinely a robot.
(b) If a visitor is genuinely a human, there is a 0.0068 probability that they will be marked (fail at least one test).
(c) Consider a visitor who is detected in (c). There is a 0.9 percent probability that the visitor is a robot.
This is due to the difference between the likelihood of a robot being flagged (0.957) and the likelihood of a human being flagged (0.0068). Therefore, the likelihood that a visitor who has been marked is a robot is 0.957 / (0.957 + 0.0068) = 0.9.
Probability is a measure of the possibility of an event occurring in probability theory. A number between 0 and 1, where 0 denotes impossibility and 1 denotes certainty, is used to express it. An occurrence is more likely to occur the higher its probability. When there is uncertainty about the result of random phenomena like coin tosses or dice rolls, probability is utilized to characterize those events. It is also used to describe more foreseeably occurring occurrences like the occurrence of an earthquake or the adoption of a particular law.

The measure of the angle m∠RQS subtended by the arc RS at the circumference is equal to 70°
What is angle subtended by an arcThe angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.
arc RS = 2(m∠RQS)
Also arc AD = 140°
2(m∠RQS) = 140°
m∠RQS = 140°/2 {divide through by 2}
