The best measure for evaluating the relative contributions of the individual predictors in a multiple regression is β.
Obtain the standardized coefficients. Regression Sum up the absolute value of all standardized coefficients. Divide every individual standardized coefficient estimate by using the sum and multiply by one hundred to attain the contribution of every predictor variable.may additionally.
Normally variable with highest correlation is a great predictor. you can also examine coefficients to pick the pleasant predictor additionally look exchange in squared cost. Relative significance is described because the percentage development with admire to the maximum essential predictor. Relative importance is calculated with the aid of dividing every variable importance rating by the most important importance rating of the variables.

Answer:
i believe it is d as the angle could also be a right angle
Step-by-step explanation:
Answer:
x = number of packets of strawberry wafers = 4 packets
y = number of packets of chocolate wafers = 18 packets
Step-by-step explanation:
Devon and his friends bought strawberry wafers for $3 per packet and chocolate wafers for $1 per packet at a carnival. They spent a total of $30 to buy a total of 22 packets of wafers of the two varieties.
Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Devon and his friends bought at the carnival. Define the variables used in the equations. (5 points)
Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer. (5 points)
A.
Let
x = number of packets of strawberry wafers
y = number of packets of chocolate wafers
x + y = 22
3x + y = 30
B. Solve the equation in A using elimination method
x + y = 22 (1)
3x + y = 30 (2)
subtract (1) from (2) to eliminate y
3x - x = 30 - 22
2x = 8
x = 8/2
x = 4
Substitute x = 4 into (1) to solve for y
x + y = 22 (1)
4 + y = 22
y = 22 - 4
y = 18
x = number of packets of strawberry wafers = 4 packets
y = number of packets of chocolate wafers = 18 packets
