In a class, one third of the students like badminton, three-fourth of the students like football, 5 out of 6 of
the students like volleyball, 60 like football and volleyball, 65 like volleyball and badminton,
17 like badminton and football, 20% of the students like all three games and 8 students don't like any
game. Draw a Venn-diagram and find the total number of students in the class.
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

Suppose the height of a ball in feet is given by the quadratic equation below, where T is in seconds. What expression will give the time when the ball reaches its maximum height? h=-16t^2+50t+8. Please look at the image for the available answers. Thank you.
Answer:
t = -50/(2 * (-16))
Step-by-step explanation:
For quadratics of the form
y = ax^2 + bx + c
the x coordinate of the vertex is
x = -b / 2a
----------------------
h = -16t^2 +50t + 8
a = -16
b = 50
t at Vertex
t = -50/(2 * (-16))

Find an ordered pair that represents the vector from (-3.7,2) to (-4, -5).
a.
(-7.7,-3)
c.
(1.3,7)
b.
(-0.3,-7)

(7.7,3)
Please select the best answer from the choices provided
A
B
C
D
Given:
A vector from (-3.7,2) to (-4, -5).
To find:
An ordered pair that represents the vector
Solution:
If [tex](x_1,y_1)[/tex] is the initial point and [tex](x_2,y_2)[/tex] is the terminal point of a vector, then ordered pair that represents the vector is:
[tex](x_2-x_1,y_2-y_1)[/tex]
A vector from (-3.7,2) to (-4, -5). So, the ordered pair that represents the vector is:
[tex](x_2-x_1,y_2-y_1)=(-4-(-3.7),-5-2)[/tex]
[tex](x_2-x_1,y_2-y_1)=(-4+3.7,-7)[/tex]
[tex](x_2-x_1,y_2-y_1)=(-0.3,-7)[/tex]
Therefore, the correct option is b, i.e., (-0.3,-7).
Sophie caught twice as many fish as her
dad. If her dad caught Ffish, how many
fish did Sophie catch?
A. F + 2
B. F-2
C. Fx 2
D. F/2
Answer:
C. F × 2
Step-by-step explanation:
Twice as many infers multiplication. Since Sophie caught twice as many as her dad, then we would multiply the number of her dad's caught fish by 2. The question states her dad's caught fish is represented by variable F so it would be:
F × 2

Answer:
x = 12
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of its opposite interior angles in a triangle
∠CBV is an exterior angle and ∠BCD and ∠CDB are ∠CBV's opposite interior angles
This means that ∠BCD + ∠CDB = ∠CBV
If we are given that ∠CBV = 9x - 3, ∠BCD = 5x + 15 and ∠CDB = 30
Then 9x - 3 = 5x + 15 + 30
^ (Note that we just created an equation we can use to solve
for x )
We then use the equation we created to solve for x
9x - 3 = 5x + 15 + 30
step 1 combine like terms
30 + 15 = 45
we now have 9x - 3 = 5x + 45
step 2 add 3 to each side
-3 + 3 cancels out
45 + 3 = 48
we now have 9x = 5x + 48
step 3 subtract 5x from each side
9x - 5x = 4x
5x - 5x cancels out
we now have 4x = 48
step 4 divide each side by 4
48 / 4 = 12
4x / 4 = x
we're left with x = 12
Answer:
30+5x+15=9x-3
9x-5x =45+3
4x=48
x =12

George has to pay $30 in taxes for every $100 that he earns. Last summer, he earned $3680. How much did he pay in taxes?(must use direct proportion) pleaseee help
Answer:
$1,140
Step-by-step explanation:
Step 1: Set up a fraction and solve (We are doing this to make it simpler to solve. So let us use "x" to represent how much he paid in taxes. )
[tex]\frac{30}{100}=\frac{x}{3680}[/tex]
Step 2: Solve; Divide the given values (The given values are 100 over 30. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.3 once divided)
[tex]\frac{30}{100}[/tex]
Cancel both zeros
[tex]\frac{30}{100}\\\\= \frac{3}{10}[/tex]
Divide
[tex]\frac{3}{10}\\\\= 3 \div 10\\\\= 0.3[/tex]
Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)
[tex]0.3\\\\0.3 \times 3680\\\\=1140[/tex]
Therefore, George paid 1140 dollars in taxes last summer.

Determine the probability of three sunny days in a row when the probability of rain on each day is 20%
A) 80 %
B) 0.8%
C) 51.2%
D) 60 %
The probability of 3 sunny days in a row is P = 0.512, so the correct option is C.
How to find the probability?We know that the probability of rain each day is 20%. Then the probability of a sunny day is 100% - 20% = 80%.
Writing this probability in the decimal form we get 0.8.
Now, to get 3 sunny days in a row, we need to have the probability 0.8 3 times (and remember that the probabilities multiply between them) so the joint probability is:
[tex]P = (0.8)^3 = 0.512[/tex]
To get it in percentage form, we multiply it by 100%.
P = 0.512*100% = 51.2%
So the correct option is C.

Step-by-step explanation:
Complement means that the 2 angles add up to 90 so:
x + 52 = 90
x = 90 - 52
x = 38
please show your work
Answer:
52
Step-by-step explanation:
If JK bisects the angle, the two angles are equal
6x+2 = 8x-6
Subtract 6x from each side
6x-6x+2 = 8x-6x-6
2 = 2x-6
Add 6 to each side
2+6 =2x-6+6
8 =2x
Divide by 2
8/2 =2x/2
4 =x
Now find angle LJM, which is the sum of the two angles
6x+2 + 8x-6
14x -4
14*4-4

Answer:
D) 52
Step-by-step explanation:
since htere is an angle bisector that means that (6x+2) and (8x-6) are equal to each other
so

(2+x)5=11
Answer:
x = 0.2
Step-by-step explanation:
Distribute the 5 to (2 + x) to make it 10 + 5x = 11. You can rewrite it to make it 5x + 10 = 11 to make it easier if you want but you dont have to. Subtract the ten from both sides to make it 5x = 1. Divide both sides by 5 to get 0.2. If you want to double check your answer you can substitute 0.2 in for x in (2 + x)5 = 11 or in 5x + 10 = 11. It doesn't matter which.
