Evil Kanevil is getting ready to perform a death defying stunt for a large crowd of people. He plans to jump over a row of cars from a ramp that from base to base is 8 feet long and is tilted at a 40 degree angle. Evil needs to be at least 7 feet in the air to clear the cars, otherwise he'll crash and his stunt career will be over. Find out if the technicians built the ramp high enough for Evil.​

x = 3 ± √(5+y)

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

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.

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
