In the u. s, the iq test has a normal distribution with a mean of 100 and a standard deviation of 15. what percent of the population has an iq more than 133?

1.32%

Step-by-step explanation:

First, find the z-score:

z = (x − μ) / σ

z = (133 − 100) / 15

z = 2.2

Use a calculator or z-score table to find the probability.

P(x > 2.2) = 1 − 0.9868

P(x > 2.2) = 0.0132

1.32% of the population has an IQ more than 133.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
