The first thing you should do is add up the first numbers -
* 20 + 15 + 16 = 51 :)
* 16 + 19 + 17 = 52
Now divide each of the scores by the amount of numbers there is -
* 20 (1) 15 (2) 16 (3)
* 16 (1) 19 (2) 17 (3)
51 ÷ 3 = 17 (Rolanda's Average Score)
- Which # is bigger?
52 ÷ 3 = 17.3 (Jetta's Average Score)
Mean: The mean is the average of the numbers; a calculated (central) value of a set of numbers.
How to find it? We add all of the scores together and then divide them by the number of scores.
They gave us the numbers 20, 15, and 16
1st. Lets add
20 + 15 + 16 = 51
2nd. Divide by 3 since their are 3 test scores
51 ÷ 3 = 17
So rolanda's mean is 17!

So jetta's mean is 17.333333333333333
Now lets compare:)
Rolanda's mean = 17
Jetta's mean = 17.33333333333333333
Obviously, whos is bigger?

Answer:
The better buy is The denim shoppe!
Step-by-step explanation:
the denim shoppe price for 3 jeans is $56 and Jeans jam price of 3 jeans is $56.25! $56 < $56.25.
If Ava buys three pairs of jeans from Jeans Jam, it would cost her a total of $56.23. If Ava buys three pairs of jeans from The Denim Shoppe, it would cost her exactly $56. This means that The Denim Shoppe is a better buy...by 23 cents.

The ratio of 34% is 17:50.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
34%
This can be written as,
34/100
= 17/50
This can be written as a ratio,
= 17:50
Thus,
The ratio is 17:50.

Third: 20x = 3 * 100
Fourth/Final: x = 3*100/ 20 = 15

x = 300/20
x = 30/2
x = 15
