A set of final examination grades in an introductory statistics course is normally distributed, with a mean of 77 and a standar

Shalnov [3]

Answer:

0.9007 is the probability that a student scored below 86 on this exam.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 77

Standard Deviation, σ = 7

We are given that the distribution of examination grades is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(student scored below 86)

P(x < 86)

$P( x < 86) = P( z < \displaystyle\frac{86 - 77}{7}) = P(z < 1.2857)$

Calculation the value from standard normal z table, we have,

$P(x < 1.2857) = 0.9007 = 90.07\%$

0.9007 is the probability that a student scored below 86 on this exam.

The perimeter of a school gym is 522 feet. The gym measures 80 feet wide. Determine the length of the school. PLEASE EXPLAIN THE

lidiya [134]

Total perimeter is 522 ft. I will guess the gym is a big rectangle.

Therefore, Perimeter of a rectangle = 2L + 2W
P= 2L+ 2W

We know 80 ft wide. so now we plug and chug the equation we came up with

P=522 ft
P=2L+ 2(80)

522=2L+ 160

L= 181

hope that helps
