Answer:
75 is 75% of 100
Step-by-step explanation:
Using a calculator, inserting the values of x and y, the correlation coefficient for the given data-set is of -0.9422.
<h3>How to find the correlation coefficient of a data-set?</h3>
Using a calculator, the correlation coefficient is found inserting the ordered pairs (x,y) in the calculator.
In this problem, we have that:
- The values of x are: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5.
- The values of y are: 112.5, 110.875, 106.8, 100.275, 91.3, 79.875, 70.083, 59.83, 30.65, 0.
Hence, using a calculator, the correlation coefficient is of -0.9422.

Lol, I am learning about this too!! The trick is to add 60 and 25. Meaning your answer is B. (85)
(3 x 2.5) x 2 would be your answer
Answer:
You can only buy 29 pencils with $2.95
Each pencil costs $0.10. You'd be able to buy 29 pencils and keep $0.05
You can't buy an extra pencil with $0.05. You need $0.10 to buy a pencil.
Step-by-step explanation:
P=Pencils(s)
n=Number of pencils that can be bought for $2.95
-------------------
nP=$2.95
----------------
But 6P=$0.59
So P=($0.59)/6
------------------
Therefore:
n($0.59/6)=$2.95
n=($2.95)/($0.59/6)
n=30
(Hope this helps can I pls have brainlist (crown) ☺️)
