1.The fit line equation for the scatterplot is y=-2.61x+152.51, where x is Variable 1 and y is Variable 2. According to the equation, what is the expected value of y when the x-value is 45? 2.If the required value of y is -108.5, use the fit line equation y=-2.61x +152.51 to determine the needed x-value. Round to the nearest whole number.

the answer is 4.8 units on e2020.

okay wait before i answer, is this for your points on a graph?

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
