Answer:

B is correct.

Step-by-step explanation:

I eliminate A and B since it translates the pentagon left or right. D dilates, but does not make it bigger since the value is a fraction less than 1. 9/4 is correct because the value of that is greater than 1 and therefore makes the pentagon bigger.

Answer:

24 Cats.

Step-by-step explanation:

You can set up an inequality of 21/18 and 28/x.

Multiply 18 and 28, you get 504. Divide 504 by 21 and you get your answer of 24.

25 cats because if you see the difference between cats and dogs it is 3 keeping the same ratio would mean subtract 3 from 28 therefore the answer is 25

Step-by-step explanation:

A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 15% discount on your purchase that day. If the card is an odd number greater than 6, you get a 40% discount. Otherwise, you get a 25% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? Use pencil and paper. If the manager of the store wants approximately half of the customers to receive the 25% discount, does this seem like an appropriate method?

Answers

Answer:

The answer would be A. 1 1/5

48/40 = 1 8/40

1 8/40 Simplify to 1 1/5

Step-by-step explanation:

If the store wants to give approximately half of the customers a 25% discount. They may need to adjust the discount criteria or randomly assign cards to customers to achieve the desired frequency.

What is the relative frequency?

The ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space, but in an actual experiment, is the relative frequency or experimental probability of an event.

To determine the relative frequency for each discount, we need to count the number of customers who received each type of discount and divide by the total number of customers.

Let's create a table to organize the data:

Discount Card Label Number of Customers

15% Even 120

40% Odd > 6 30

25% Other 250

Total 400

The relative frequency for each discount is given by:

Relative frequency of 15% discount: 120/400 = 0.3 or 30%

Relative frequency of 40% discount: 30/400 = 0.075 or 7.5%

Relative frequency of 25% discount: 250/400 = 0.625 or 62.5%

To determine whether this discount method is appropriate to give approximately half of the customers a 25% discount, we need to compare the observed frequency of the 25% discount with the desired frequency.

Half of the 400 customers is 200. If we want approximately half of the customers to receive the 25% discount, then the observed frequency of the 25% discount should be close to 200.

However, we see that the observed frequency of the 25% discount is 250, which is higher than the desired frequency.

Estimate the sum: 1 3/7 + 3 5/9 + 1/2. Show your work.

Answers

Answer:

The correct answer is 5 61/126!

Step-by-step explanation:

Leave a fraction alone

1 3/7

Find the Addend

9x3=27+5=32 = 32/9

Find the sum and simplify

1 3/7 + 32/9 = 691/126 = 5 61/126

To estimate the sum of the given terms: 13/7, 35/9, and 1/2, we can convert each term to a decimal number and then add them together. First, let's convert 13/7 to a decimal.

To do this, we divide [tex]13 by 7: 13 ÷ 7 = 1.857[/tex] Next, let's convert 35/9 to a decimal. Dividing 35 by 9 gives us: [tex]35 ÷ 9 = 3.889[/tex] Finally, we convert 1/2 to a decimal by dividing 1 by 2:[tex]1 ÷ 2 = 0.5[/tex] Now that we have converted all the terms to decimals, we can add them together: [tex]1.857 + 3.889 + 0.5 = 6.246[/tex]

Therefore, the estimate of the sum of the given terms is 6.246. It's important to note that this is an estimate because we rounded the decimal values. If you need a more precise answer, you can use a calculator or longer division to get more decimal places. However, for most practical purposes, this estimate should suffice.
