Suppose that the sitting​ back-to-knee length for a group of adults has a normal distribution with a mean of μ=22.5 in. and a standard deviation of σ=1.1 in. These data are often used in the design of different​ seats, including aircraft​ seats, train​ seats, theater​ seats, and classroom seats. Instead of using 0.05 for identifying significant​ values, use the criteria that a value x is significantly high if​ P(x or ​greater) ≤0.01 and a value is significantly low if​ P(x or ​less) ≤0.01.Find the​ back-to-knee lengths separating significant values from those that are not significant.
A company that manufactures toothpaste is studying five different package designs. Assuming that one design is just as likely to be selected by a consumer as any other design, what selection probability would you assign to each of the package designs? We would assign a probability of to the design 1 outcome, to design 2, to design 3, to design 4, and to design 5. In an actual experiment, 100 consumers were asked to pick the design they preferred. The following data were obtained. Design Number of Times Preferred 1 10 2 5 3 30 4 40 5 15 Do the data confirm the belief that one design is just as likely to be selected as another? Explain. Yes, the sum of the assigned probabilities is 1. No, a probability of about 0.20 would be assigned using the relative frequency method if selection is equally likely. Yes, the average of the assigned probabilities is 0.20. No, a probability of about 0.50 would be assigned using the relative frequency method if selection is equally likely.

The cube of a number is less than five times the square of the number. For what set of numbers is this true?(–ꝏ, 5)
(5, ꝏ)
(–ꝏ, 0) U (0, 5)
(–ꝏ, 5) U (5, ꝏ)

Answers

Answer:

  (–ꝏ, 0) U (0, 5)

Step-by-step explanation:

The relation can be written as ...

  x³ < 5x²

  x³ -5x² < 0

  x²(x -5) < 0

This is not true for x = 0. It is true for x < 5, otherwise. Then the solution set is ...

  x ∈ {(–ꝏ, 0) U (0, 5)}

The cube of any number from the set (-∞, 0) ∪ (0, 5) is less than five times the square of the number. So, the third option is correct.

Mathematically, a set is a collection of distinct, well-defined objects forming a group.

Let the number be x.

Then, according to the question:

x³ > 5x²

x³ - 5x² > 0

x²(x - 5) > 0

x² > 0 or x - 5 > 0

x > 0 or x > 5

This implies that

x ∈ (-∞, 0) ∪ (0, 5)

Hence, the correct answer is the third option, (-∞, 0) ∪ (0, 5).

A manufacturer has a monthly fixed cost of $750 and a production cost of $15 for each item x that is produced. The product sells for $37 per item.Write the equation of the total cost function, C(x), in terms of x.
Write the equation of the total revenue function, R(x), in terms of x.
Write the equation of the profit function, P(x), in terms of x. Simplify P(x) completely.

Answers

Answer:

The cost function is C(x) = 14x + 100000,

the revenue function is R(x) = 20x,

the profit function is P(x) = R(x) − C(x) = 20x − 14x − 100000 = 6x − 100000.

Is it unusual to get 5 when a pair of dice is rolled?

Answers

It is not unusual to get 5 when a pair of dice is rolled.

What is probability?

Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes. Probability is a measure of how likely an event is going to happen.

Given is that you get 5 when pair of dice is rolled.

Number of outcomes for sum of 5 = 4

The sample space for the outcomes for sum of 5 is {(1, 4), (2, 3), (3, 2), (4, 1)}.

So, we can write the probability of getting 5 as -

P(getting 5) = 4/36

P(getting 5) = 1/9

Although the probability of getting a 5 is low, but is not completely zero. So, it is not unusual to get 5.

Therefore, it is not unusual to get 5 when a pair of dice is rolled.

Not at all. In fact, there are 4 ways to roll it:

A 1 and a 4 or a 4 and a 1

A 2 and a 3 or a 3 and a 2

There are 36 possible ways you can roll 2 dice, so those 4 possibilities represent a 4/36 = 1/9 chance of rolling a total of 5 between two dice.

3. Dan's credit card was lost on a vacation. He immediately reported it missing. The person who found it days later used it, and charged $x worth of merchandise on the card, where x > $200. How much of the $x is Dan responsible for paying?​

Answers

The question is an illustration of the Truth in Lending Act, and Dan is responsible for paying $0

Truth in Lending Act

The Truth in Lending Act is simply an act that protects people from unfair charges on their credit cards, especially in case of theft and card misplacement.

The scenarios

From the question, we have the following scenarios

  • His card got lost
  • He reported
  • Someone else saw the card and purchased goods worth over $200

Because Dan reported when his card got lost, he is protected by the Truth in Lending Act (TILA).

Hence, Dan is responsible for paying $0

Final answer:

Dan is not responsible for any of the unauthorized charges made on his lost credit card, as he reported it as lost immediately. The maximum amount he could legally be held liable for, per the Fair Credit Billing Act, is $50.

Explanation:

In a scenario where Dan's credit card is lost and reported missing, the responsibility for charged dollars rests on the card issuer, not on Dan. According to the Fair Credit Billing Act (FCBA), the legal limit he's responsible for is $50. However, given that Dan reported the card as lost immediately, he should not be held responsible for any unauthorized charges made.
