I still cant see it sorry cant help without seeing it can you spell the question?
Answer:
5 days
Step-by-step explanation:
The question above is modeled by the equation :
150 − 8x = 170 − 12x.
After how many days will both have ye same amount :
Number of days = x
Collect like terms
-8x + 12x = 170 - 150
4x = 20
x = 20/4
x = 5 days
The boys will have the same amount in their account after 5 days.
This question is asking only for the slope of the regression equation. This slope can be easily calculated using the following rule:
slope = SP / SSx
Examining the givens, we will find that both parameters are given where:
SP = 30 and SSx = 10
Substituting with the givens in the above mentioned equations, we can calculate the slope as follows:
slope = 30 / 10 = 3
