Although controversial and the subject of some recent law suits, some human resource departments administer standard iq tests to all employees. one iq test's scores are well modeled by a normal model with mean 100 and standard deviation 10. if the applicant pool is well modeled by this distribution, a randomly selected applicant would have what probability of scoring in the following regions?

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.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
