Which expression simplifies to 41? Choose all that apply! Question options:

A. 10 + 2³ ∙ 4 - 1

B. 10 + 2³ ∙ (4 - 1)

C. (10 + 2³) ∙ 4 - 1

D. 10 + (2³ ∙ 4) - 1

The first one is v^10+ 31

The second one is v^10 + 24

3rd is 72v- 1

last one is v^10 + 31

Which on adds up to 41

Step-by-step explanation:

A,  D

Step-by-step explanation:

The answer is A because 10+2^3*4-1=41 and D because 10+(2^3*4)-1=41 as well

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
