Answer:
Step-by-step explanation:
For this case we have a linear model given by:
Where X= represent the height.
Y= represent the beats per minute
And the slope is given by and the intercept
We have the mean for x and y given also
And in order to find the best predicted value we just need to replace the value of X= 65, and we got this:
If we want a confidence interval for the response variable when the predictor variable is x, is given by this formula:
And if we replace we got this:
But for this case since we don't have the deviation we can just express it like this.

Step-by-step explanation:
Answer:
x = 2 and x = 10
Step-by-step explanation:
(x+3)^2 = (x - 5)^2 + (x + 2)^2
x^2 + 6x + 9 = x^2 - 10x + 25 + x^2 + 4x + 4
x^2 + 6x + 9 =2x^2 - 6x + 29
x^2 - 12x + 20 = 0
(x - 10)(x - 2) = 0
x - 10 = 0; x = 10
x - 2 = 0; x = 2
