In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95
blagie [28]

Answer: 0.0228

Step-by-step explanation:

Given : In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95 with a standard deviation of 10.

i.e. \mu=95\ \ \&\ \sigma=10

Let x denotes the scores.

We assume that the scores are normally distributed.

Then, the proportion of individuals in this population have a score greater than 115 will be :-

P(x>115)=1-P(x\leq115)\\\\=1-P(\dfrac{x-\mu}{\sigma}

Hence , the proportion of individuals in this population have a score greater than 115 = 0.0228

Give two coterminal angles (one positive and one negative) and the reference angle -4 pi/5
kherson [118]

The coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.

<h3>What is coterminal angles?</h3>

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle:

-4π/5

To find the coterminal angle, add and subtract by 2π in the angle -4π/5

Coterminal angle:

= -4π/5 - 2π

= -14π/5

= -4π/5 + 2π

= 6π/5

Reference angle:

= π - 4π/5  (as the angle lies in the second quadrant)

= π/5

Thus, the coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.
