A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 500 feet. Determine the​ flag's length and width if the length is 130 feet greater than the width. Use pencil and paper. Write three situations to which you could apply the resulting system of equations. What is the​ flag's width?

could you reply to this with the question so i can ?

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

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.
