The owner of a video game store creates the expression −2x^2 + 24x + 174 to represent the store's weekly profit in dollars, where x represents the price of a new video game. Choose the equivalent expression that reveals the video game price that produces the highest weekly profit, and use it to determine the price.−2(x^2 − 12x) + 174; x = $12−2(x^2 − 12x − 87); x = $87−2(x − 6)2 + 246; x = $246−2(x − 6)2 + 246; x = $6

If there are 16 ounces in a pound how manyh are in 24 ounces

Answers

16 ounces = 1 pound
1 ounce = 1/16 pound
24 ounces = 1/6 x 24 = 4 pounds

Answer: 4 pounds

Final answer:

24 ounces equals 1.5 pounds, based on the conversion factor of 1 pound equals 16 ounces.

Explanation:

Your question is related to unit conversion. If we know that one pound equals 16 ounces, then to convert 24 ounces to pounds, we must divide 24 ounces by the number of ounces in a pound. Here's how we can do it:

Set up the conversion: 24 oz / 16 oz/lb.
Dividing these amounts gives the result: 24 / 16 = 1.5 lbs.

S, this means that 24 ounces is equal to 1.5 pounds.

Researchers wanted to determine if having a refrigerator in the bedroom is associated with obesity. The researchers administered a questionnaire to 353 twelve-year-old adolescents. After analyzing the results, the researchers determined that the body mass index of the adolescents who had a refrigerator in their bedroom was significantly higher than that of the adolescents who did not have a refrigerator in their bedroom. Complete parts (a) through (e) below. Why is this an observational study?

(A) This is an observational study because the researchers observe the behavior of the individuals in the study without trying to influence an explanatory variable of the study.
(B) This is an observational study because the researchers try to influence the outcome of the study.
(C) It is not an observational study

Answers

Answer:

Step-by-step explanation:

Final answer:

The question's study is an observational study because researchers observed the behavior of individuals without influencing any aspect of the study, such as the presence of a refrigerator or the adolescent's BMI.

Explanation:

This study is indeed considered an observational study. The answer is (A) This is an observational study because the researchers observe the behavior of the individuals in the study without trying to influence an explanatory variable of the study. In the study described, researchers merely observed and recorded the behavior (having a refrigerator in the bedroom) and the outcome (body mass index or BMI). There was no attempt by the researchers to manipulate or control either the presence of the refrigerator or the adolescent's BMI, which is characteristic of an observational study.

Which of the following values cannot be probabilities? 0.04, 5 divided by 3, 1, 0, 3 divided by 5, StartRoot 2 EndRoot, negative 0.59, 1.49 Select all the values that cannot be probabilities. A. 1.49 B. 1 C. three fifths D. StartRoot 2 EndRoot E. five thirds F. 0 G. negative 0.59 H. 0.04

Answers

Answer:

A. 1.49

D. √2

E. five thirds

G. - 0.59

Step-by-step explanation:

In order to be a probability, a value must be at least zero, or at most 1:

$0 \leq P\leq 1$

Evaluating each of the given values:

A. 1.49

1.49 is at least zero but it is greater than one, therefore 1.49 cannot be a probability.

B. 1

1 represents a probability of 100%, therefore this value can be a probability

C. three fifths

$0\leq (3)/(5) \leq 1$

Can be a probability

D. √2

$\sqrt 2 =1.41 > 1$

Cannot be a probability

E. five thirds

$(5)/(3)=1.67>1$

Cannot be a probability

F. 0

0 represents a probability of 0%, therefore this value can be a probability

G. - 0.59

Negative values cannot be probabilities.

H. 0.04

$0\leq 0.04 \leq 1$

Can be a probability

Final answer:

Probabilities are values ranging from 0 to 1, inclusive. With this in mind, values 5/3, √2, -0.59, and 1.49 cannot be probabilities as they're either below 0 or above 1.

Explanation:

In the field of mathematics, specifically in statistics, a probability represents the likelihood of an event occurring and is always a value between 0 and 1, inclusively. The value 0 means that an event will not happen, whilst 1 means the event is certain to happen. Therefore, any value less than 0 or greater than 1 cannot be a probability.

Given the values: 0.04, 5 divided by 3, 1, 0, 3 divided by 5, √2, negative 0.59, and 1.49, the values that cannot be probabilities are:
