Please help!! The picture has the question.

8, the absolute value of -5 is 5 and 3 is 3. 5+3=8, 8 is your answer

The answer is 8

Step-by-step explanation:

The "l l" signs mean "absolute value" which means the distance the number is from zero on a number line. This means that the absolute value of a number will always be a positive number.

l-5l + l3l = 5 + 3

5 + 3 = 8

Hope this was helpful, have a great rest of your day! :)

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.
