Answer 1
Answer:

Answer:

N=21

Step-by-step explanation:

20-3+12/6x2=N

20-3+2x2=N

20-3+4=N

21=N

Answer 2
Answer: 20 - 3 + 12/6 x 2 = N
20 - 3 + 2 x 2 = N

Sonia uses a gift card to purchase a $5.87 gourmet coffee each week. Find the total change in the gift card balance after 3 weeks.

Answers

Based on the available information, and options in the question, the total change in the gift card balance after 3 weeks is option A. -$17.61

What is Evaluation in Mathematics?

Evaluation in Mathematics is a method that is used to find the value of the expression when the variable is replaced by a given number.

In this case, to find the total change in the gift card balance after 3 weeks, calculate the total amount spent on gourmet coffee during this period.

Given that Sonia purchases a $5.87 gourmet coffee each week the total amount spent on coffee after 3 weeks can be calculated as follows:

Total amount spent = cost per coffee * number of weeks

= $5.87 * 3

= $17.61

Therefore, Sonia will have spent a total of $17.61 on gourmet coffee after 3 weeks, which will be $-17.61 of the top change in the gift card.

Hence, in this case, it is concluded that the correct answer is option A. -$17.61

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.

Answers

Answer:

Correct option: "No, a probability of about 0.20 would be assigned using the relative frequency method if selection is equally likely."

Step-by-step explanation:

The assumption made is that all the 5 different packages are equally likely, i.e. the probability of selecting a package is (1)/(5)=0.20.

The probability distribution is shown below.

According to the probability distribution:

  • The probability of a person preferring design 1 is,

        P(X=1)=0.10

  • The probability of a person preferring design 2 is,

        P(X=2)=0.05

  • The probability of a person preferring design 3 is,

        P(X=3)=0.30

  • The probability of a person preferring design 4 is,

        P(X=4)=0.40

  • The probability of a person preferring design 1 is,

        P(X=5)=0.15

So it can be seen that the probability of preferring any of the 5 designs are not same.

Thus, the designs are not equally likely.

The correct option is "No, a probability of about 0.20 would be assigned using the relative frequency method if selection is equally likely."

The selection Probability determined using the relative frequency method do not match the assigned probabilities, suggesting that the data do not confirm the belief that one design is as likely to be selected as another.

The given data can be used to calculate the relative frequencies of each package design selected by the consumers.

To determine the selection probabilities using the relative frequency method, divide the number of times a design was preferred by the total number of consumers.

For example, for design 1, the selection probability would be 10/100 = 0.1.

Similarly, for design 2, the selection probability would be 5/100 = 0.05.

The selection probabilities for designs 3, 4, and 5 would be 0.3, 0.4, and 0.15 respectively.

Comparing these probabilities to the assigned probabilities, it can be observed that the assigned probabilities do not match the observed relative frequencies, indicating that the data do not confirm the belief that one design is just as likely to be selected as another.

Beverly has a backyard that is square. One of the sides is 10 feet long. What is the area of her back yard?

Answers

Answer:

100 ft sq.

Step-by-step explanation:

A square means all sides are equal.

Area = bxh

10 ft x 10 ft = 100 ft sq.

Answer:

The area is 100 ft^2

Step-by-step explanation:

A square has 4 equal sides so if one side is ten then all of the sides are 10

Suppose you're given the formula q = 2o + 6p. If you know that p = o – 7, how could you rewrite the formula?

Answers

Answer:

q = 8o - 42

Step-by-step explanation:

Given:  The given formula is q = 2o + 6p.

p = o – 7

Now we have to plug in p = o - 7 in the given formula, we get

q = 2o + 6(o - 7)

Now we use the distributive property a(b-c) =ab - ac and expand.

q = 2o + 6o -6(7)

q = 2o +6o - 42

Here 2o and 6o are the like terms, we can add them

q = 8o - 42

q = 2o + 6p

p = o – 7

⇒ q = 2o + 6(o - 7) = 2o + 6o - 6 × 7 = 8o - 42

⇒ q = 8o - 42
