Answer: c. 91
Step-by-step explanation:
Given : A linear regression equation was computed to predict the final exam score from score on the midterm exam.
The equation of the least squares regression line was
, where y= the final exam score
x= the midterm exam score.
if Joe score a 90 on the midterm exam, the put x= 90 in the above eqaution , we get
Hence, the predicted value of his score on the final exam would be 91.
Therefore , the correct answer is c. 91 .
Answer:
The sum is .
Step-by-step explanation:
Consider the provided information.
The given expression are - 10t and t - 10t
We need to find the sum of the opposite of -10 t and t - 10t.
The opposite of -10 t is 10 t.
Remove the parenthesis.
Simplify the number
Use Additive inverse.
Hence, the sum is .
Answer:
Step-by-step explanation:
Given a circle centred at the point P(-4,-6) and passing through the point
R(2,2).
To find its equation, we follow these steps.
Step 1: Determine its radius, r using the distance formula
For point P(-4,-6) and R(2,2)
Step 2: Determine the equation
The general form of the equation of a circle passing through point (h,k) with a radius of r is given as:
Centre,(h,k)=P(-4,-6)
r=10
Therefore, the equation of the circle is:
