Answer:

54

Step-by-step explanation:

Estimate=Population size × Sample proportion

population size =  120

sample proportion = (9)/(9+6+5) = 9/20 (check on Cymath as a resource)

estimate = 120 x 9/20 = 54

There are 28.35 grams in an ounce and 2.21 pounds in a kilogram. Miriam converted 7 kilograms to ounces, but her answer is not c
sergejj [24]

Answer: OPTION C.

Step-by-step explanation:

For this exercise it is important to remember the following:

1\ kilogram=1,000\ grams

Knowing this and based on the information provided in the exercise, you can make the conversion from kilograms to ounces. This is:

(7\ Kg)(\frac{1,000\ gr}{1\ Kg})(\frac{1\ oz}{28.35\ gr})=246.913\ oz

According to the exercise, Miriam's procedure was:

 (7\ Kg)(\frac{1,000\ gr}{1\ Kg})(\frac{28.35\ gr}{1\ oz})= 198,450\ oz

So you can identify that she made a mistake.

Notice that:

1. Miriaim multiplied correctly.

2. Butt the third fraction should be \frac{1\ oz}{28.35\ gr} and not \frac{28.35\ gr}{1\ oz}.

The amount of water that the girls on the basketball and soccer teams drink during one practice session is recorded in the dot p
Radda [10]

Answer:

<h2>B. 30 oz less than.</h2>

Step-by-step explanation:

We have two dot plots, one for the Basketball Team and one for the Soccer Team.

Notice that there are 16 girls in the Basketball Team and 16 girls in the Soccer Team.

Basically, the median is between the 8th and 9th term in each data set. Specifically, is the mean between them.

<h3>For Basketball Team</h3>

m_{basketball} =\frac{32+32}{2}=32

Because the 8th and 9th term are both equal to 32.

<h3>For Soccer Team</h3>

m_{soccer}=\frac{64+64}{2}=64

Because the 8th and 9th term are both equal to 64.

If we subtract them to find the difference, it would be

\Delta m=64-32=32

Basically, the Soccer Team drank 32 more ounces of water than the Basketball Team.

Therefore, the right answer is B, that's the closest one.

1) If B is between A and C, AB=10 and AC=28, what is the value of BC?
Shalnov [3]

One

AB + BC = 28

AB = 10

10 + BC = 28

BC = 28 - 10

BC = 18

Two

AB + BC = AC

AB = 6x

BC = 8x

6x + 8x = 42

14x = 42

x = 42/14 = 3

Three

AB = 2x - 1

BC = 3x + 5

AB + BC = 24

2x - 1 + 3x + 5 = 24

5x + 4 = 24

5x = 24 - 4

5x = 20

x = 20/5

x = 4

AB = 2x - 1

AB = 2*4 - 1

AB = 7
