Answer:
use symbolab
Step-by-step explanation:
S= 25
To find the rest you just do 180-25
Percentage of students with GPA between 1.5 and 3.5 is 75% and Percentage of students that don't belong to freshmen is 73.9%.
<h3>How to Calculate the Percentage?</h3>
1) Total number of households with computer = 111,804
Percentage of Cincinnati households with computer = 82.1%
Thus;
Number of Cincinnati households with computer = 82.1% * 111804 ≈ 91791
2) Total number of students = 854
Percentage of students with GPA between 1.5 and 3.5 = 100 - (11 + 14) = 75%
3) Total number of students = 854
Number of freshmen = 223
Thus;
Percentage of students that don't belong to freshmen = 1 - (223/854) = 1 - 0.2611 = 0.7389 ≈ 73.9%
4) We are given;
17% of the 198 seniors are on Academic Watch
10% of 223 freshmen are on Academic watch
Thus;
a) seniors on academic watch = 17% * 198 ≈ 34
b) freshmen on academic watch = 10% * 223 ≈ 22
c) Number of more seniors that freshmen on academic watch = 34 - 22 = 12

The product of the vectors v and w is gotten as; v ⋅ w = 22
<h3>What is the product of the vectors?</h3>
We are given the vectors;
r = <8, 8, -6>
v = <3, -8, -3>
w = <-4, -2, -6>
We want to evaluate v.w which is a product of both vectors.
The formula will be;
v.w = (v_x * w_x) + (v_y * w_y) + (v_z * w_z)
Plugging in the values and solving gives;
v.w = (3 * -4) + (-8 * -2) + (-3 * -6)
v.w = -12 + 16 + 18
v.w = 22
We can conclude that the vector expressions has a product of 22

Answer:
22
Step-by-step explanation:
mean is calculated as
mean = 
Given the mean of 12 numbers is 20 , then
= 20 ( multiply both sides by 12 )
sum = 240
Given the mean of 8 numbers is 25 , then
= 25 ( multiply both sides by 8 )
sum = 200
Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is
mean = 
= 22
