Answer:
fail to reject the null hypothesis
Step-by-step explanation:
Based on the information provided I would fail to reject the null hypothesis. This is because the Miles per gallon that the independent testing firm has concluded for the car nearly matches the car's MPG claim. The difference being 0.1 . Since the standard deviation is 1.1 for this test, this means that the average falls perfectly within this range and makes the data very compelling. Combine this with a very low level of significance, I would say that the claim is backed by the data.
Answer:
x + 4y = 51
x = -4y + 51
Substitution
-3(-4y + 51) + 5y = 85
Distribution
12y - 153 + 5y = 85
Combine like terms
17y = 238
y = 14
x = -4(14) + 51
x = -7
