2x = 7 + 3
2x = 10
x = 10/2
x = 5
S: {5}
15/hr
15x5 = 75 dollars. you can build the ratio table using the rate of change.
So first we start with division:
$750 divided by 2 equals $375.
Since one employee gets more than the other, we need to add more onto his/her salary.
So, next is addition.
$375 plus $200 equals $575.
So, one employee makes $375 while the other has an increase in his salary, so they get paid $575.
Hope I helped you!
Part A
Correlation coefficient: -.99
This tells us that as time goes on (value of x increases) the area of the puddle goes down (value of y decreases)
Part B
y₂ - y₁
------- = slope
x₂ - x₁
9 - 15
--------
5 - 8
-6/-3 = 2
So the slope equals -2, regardless of the fact that we got 2 as an answer there, we know that it is a negative slope
Part C
The data represents causation because an increase in the value of x results in a decrease in the value of y, this shows an example of direct causation between x and y.
It would be in a radius between 6*200 and 8*200
