In 2018 the scores of students on the May SAT had a normal distribution with mean u = 1450 and a standard deviation of o = 120. a. What is the probability that
a single student randomly chosen from all those taking the test scores 1500 or higher?

b. If a sample of 50 students is taken from the population, what is the probability that the sample mean score of these students is 1470 or higher?

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
