Answer:
The answer is below
Step-by-step explanation:
Let B represent those that like badminton, F represent those that like football and V represent those that like volleyball. Let x represent the total number of people.
n(B) = (1/3)x, n(F) = (3/4)x, n(V) = (5/6)x
n(B∩F∩V) = 20% of x = 0.2x
n(B∩F) = 17, hence n(B∩F∩V') = 17 - 0.2x
n(V∩F) = 60, hence n(B'∩F∩V) = 60 - 0.2x
n(B∩V) = 65, hence n(B∩F'∩V) = 65 - 0.2x
n(B∪F∪V)' = 8
n(B∩F'∩V') = (1/3)x - 0.2x - (17 - 0.2x) - (65 - 0.2x) = 0.533x - 82
n(B'∩F∩V') = (3/4)x - 0.2x - (17 - 0.2x) - (60 - 0.2x) = 0.95x - 77
n(B'∩F'∩V) = (5/6)x - 0.2x - (60 - 0.2x) - (65 - 0.2x) = 1.033x - 125
Therefore:
x = n(B∩F'∩V') + n(B'∩F∩V') + n(B'∩F'∩V) + n(B∩F∩V) + n(B∩F∩V') + n(B'∩F∩V) + n(B∩F'∩V) + n(B∪F∪V)'
x = (0.533x - 82) + (0.95x - 77) + (1.033x - 125) + (0.2x) + (17 - 0.2x) + (60 - 0.2x) + (65 - 0.2x) + 8
x = 2.1166x - 134
1.1166x = 134
x = 120
Therefore there was 120 students
<u>Explanation:</u>
The sign of the product of any odd number of negative integers is positive because when two minuses are multiplied with each other, it will result in a positive number.
<u>For example:</u>
- -3 x -5
- => -1 x -1 x (3 x 5)
- => 1 x (3 x 5)
- => 15 (Which is positive)

Answer:
17$
Step-by-step explanation:
Round $17.46 to the Nearest Dollar
This is how to round 17.46 dollars to the nearest dollar.
First, note that $17.46 is the same as 17 dollars and 46 cents.
To round $17.46 to the nearest dollar, means to round $17.46 to a full dollar amount with no cents.
The rounding rule for dollars is as follows: If it is 50 or more cents, you add to the dollar amount. Otherwise, you simply delete the cents.
In $17.46, 46 cents is less than 50, so you simply delete the cents.
$17.46 rounded to the nearest dollar is therefore:
$17
