Step-by-step explanation:
Here is the answer to this question,
His hypothesis would be:
Null hypothesis:
H0: μ(new) - μ(regular) = 0
Alternate hypothesis:
H1: μ(new) - μ(regular) > 0
The consumer is testing to know if his new detergent is better off in cleaning than the regular. The question says that higher scores after cleaning is used to signify which is better based on sufficiently clean garment. Since he is interested in knowing the mean scores of the differences, he should use the hypothesis I stated above.

Solve.

The slope is 0 and undefined, which is our answer.
Answer:
SA = 202
Step-by-step explanation:
Surface area = Sum of all 6 areas of each side of the cuboid
SA = 2 (4·5 + 5·9 +9·4), because there are 2 of each kind of sides
SA = 2 (20+ 45 + 36)
SA = 2·101
SA = 202
Al you have to do is add 4 to the equation
This gives you g(x)=4x^2+9 which is your answer
