It is in its simplest form
Plot the given point B(3,5) and a vertical line through it:
Next draw several possibilities for A(x,3), for instance
A(-4,3), A(-1,3), A(1,3), and A(5,3
Draw a line through them:
Now you can see that the only value of x is the value where the
blue line crosses the green vertical line, which is at A(3,3)
could you mark Brainy PLS
You are right, it is $75.
If you draw a line through the points, you can see that the line is linear, meaning that the line has the same slope. The slope of the line is 3/2 or 1.5, because from each point, you are going up 1.5 units, and to the right 1 unit. From the 4th week, if you go up 1.5 units and to the right 1 unit, at the 5th week your y value will be 75.

First is the exact form
Answer:
The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.
Step-by-step explanation:
Each confidence interval has two bounds, the lower bound and the upper bound. The points estimate used to estimate the mean is the halfway point between those two bounds, that is, the sum of those two bounds divided by two.
In this problem, we have that:
Lower bound: 62.532
Upper bound: 76.478
Point estimate: (62.532 + 76.478)/2 = 69.505
The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.
