Answer:
One tailed
To conclude if there is an increase in the mean gas mileage due to new type of tire.
Step-by-step explanation:
We are given the following in the question:
The manufacture wants to compare increase in the mean gas mileage.
Population mean = 32 miles per gallon
Thus, the manufacture could carry a hypothesis test to compare mean.
A one tailed test (z-test or t-test) based on the information can be used to compare the increase in mean.
Thus,
The automotive manufacturer should perform a one tailed hypothesis test to conclude if there is an increase in the mean gas mileage due to new type of tire.
A. Garcia mixed four cups of yellow paint with one cup of red paint. So, each red paint would be four yellow paints.
B. Garcia should put four cups of red paint for each red paint. I say this because if the ratio is 4:1 that means its four yellow paints to one red paint.
C. The unit price would be $7, because if you divide 42 by 6, it's 7.
Hope this is right :)
Answer:
1
Step-by-step explanation:
f(x)=x^3+2x^2-x-1
f(1)=1^3+2(1)^2-1-1
f(1)=1+2*1-1-1
f(1)=1+2-1-1=3-1-1=2-1=1
