The test statistic used to test the overall significance of a multiple regression model, the null hypothesis that each one the -coefficients of the x-variables in the model is equal to zero, is tested against the alternative hypothesis that at least one the -coefficients of the x-variables in the model is ≠ zero, is the A) χ2 statistic
B) t statistic
C) F value from the F-distribution tables
D) F value calculated as mean square regression divided by mean square error

step-by-step explanation:

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is

happy to

pls mark as brainliest.

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74

how many friends does he have? i think some of the information got cut off in the problem.
