From National Testing data we find that College math class testing times are Normally distributed with μ = 46 minutes and σ = 3 minutes. Using the 68-95-99.7 rule, give the testing times for A = B = C = D = E = F = G = One person is randomly selected from this population. Using the 68-95-99.7 rule, find the probability that their test time is BETWEEN 40 and 52 minutes.

i dont know sorry

step-by-step explanation:

step-by-step explanation:

i think the correct option is the second option.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
