The best answer to this statistic question would be 15.7% or, if rounded off, 16%. This is because those students who have GPAs are approximately at least 1 standard deviation away from the mean and more - which means that 84% of the GPAs are less then 3 pounds. I subtracted 84 from 99.7 (which is the whole distribution's percentage) and came up with 15.7.

Molodets [167]
To find the exterior angle measure we would use the following formula: 
\frac{360~degrees }{number ~of ~sides}
A regular hexagon has 6 sides so we divide: 
360/6 which equals 60 
So our final answer would be A. 60

2. In a school of 320 students, 85 students are in the band, 200 students are on sports teams, and 60 students
Alja [10]

Answer:

<u>60</u> students are involved in either band or sports.

<u>95</u> students  are not involved in either sports or band.

Step-by-step explanation:

Given:

In a school of 320 students, 85 students are in the band, 200 students are on sports teams, and 60 students  participate in both activities.

Now, to find the students  are involved in either sports or band. And students who are not involved in either sports or band.

<em>Total number of students</em> = 320.

Number of students in the band = 85.

Number of students in the sports team = 200.

Number of students participate in both activities = 60.

Thus, 60 students are involved in either band or sports.

So, the number of students in the band adding number of students in the sports team we get:

200 + 85 = 285.

Then, to subtract the number of students participate in both activities we get:

285 - 60 = 225.

<em>Thus, the remaining students are </em>= 225.

Now, to get the students  who are not involved in either sports or band we subtract the total number of students from the remaining students:

320-225

=95.

Therefore, 60 students are not involved in either band or sports. 95 students  are not involved in either sports or band.
