Answer: See explanation
Step-by-step explanation:
The null hypothesis H0: The null hypothesis states that there is no relationship between the two things that are being considered.
The alternative hypothesis is contradictory to H0 and it explains that there is a relationship between the two selected variables.
Based on the question, the null hypothesis H0 is that the rating of car is equal to 46.7 miles per gallon. μ = 46.7 MPG
The alternative hypothesis Ha is that the rating of the car is not equal to 46.7 Miles per gallon. μ ≠ 46.7 MPG
Answer: d
(-5,3)(5,7)
Slope = change in y /change in x
M= 7-3/5-(-5)
M= 4/ 10
M=4÷2/5÷2
M=2/5
Your slope is 2/5 in fraction form or 0.4 in decimal form
(3x4)-1+2 3x4=12 and 1+2=3 so 3-12=9 hope I helped
