Okay so you have to set it up as 3.1 over 1.35 and 37.75 over x then you solve for that by doing 37.75 times 1.35 which is 50.9625 and then divide by 3.1 and you get 16.4
Answer:
Part A: Two pieces of information that are provided by the graph is the median which is 55 and the range which is 20-95. Two piece of information that is not provided by the graph is the mean and mode.

I am not sure if this is all correct, but i tired. I hope this helps :)
Answer:
2x + 5y +15
Step-by-step explanation:
x + x + y + y + 3y + 15
2x + 2y +3y +15
2x +5y + 15
We know that you have 9 quarters
We also know that you have 21 pennies
Probability is represented as "determined factor" / total
First, we need to find the total amount of possibilities. This means that you have to add 21 and 9
21 + 9 = 30
We want to know the probability of picking a penny out of the hat, so you would represent this as:
21/30
To turn it into a percent, divide 21 by 30.
21 ÷ 30 = 0.7
0.7 is equivalent to 70% as a percent
This means that you will have a 70% chance of picking a penny out
Answer: 70%
76 I'm pretty sure cuz it's across
