The time it takes an untrained rat to run a particular maze has a Normal distribution with mean 62 seconds and standard deviation 17 seconds. Researchers want to conduct a significance test to determine whether a particular training program significantly improves the completion time for the rats. State appropriate Null and alternative hypotheses. Be sure to define the variable of interest.

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
