Answer:

Total 22 students do not enjoy hip hop or pop.

Step-by-step explanation:

It is given that total number of students is 125.

A : Total number of students, who enjoy hip hop

B : Total number of students, who enjoy pop

A∩B : Total number of students, who enjoy both hip hop and pop music.

From the given information it is clear that

$A=90$

$A\cap B=63$

$A'\cap B=13$

$A'\cap=B-A\cap B$

$13=B-63$

$B=76$

Total number of students, who enjoy at least one of the music.

$A\cupB=A+B-A\cap B$

$A\cupB=90+76-63$

$A\cupB=103$

Total number of students, who do not enjoy any music.

$125-A\cupB=125-103=22$

Therefore total 22 students do not enjoy hip hop or pop.

Match the parabolas represented by the equations with their foci. Tiles y = -x2 + 4x + 8 y = 2x2 + 16x + 18 y = -2x2 + 5x + 14 y

alexdok [17]

Given:
<span>y = -x2 + 4x + 8
y = 2x2 + 16x + 18
y = -2x2 + 5x + 14
y = -x2 + 17x + 7
y = 2x2 + 11x + 5
y = -2x2 + 6x + 5

Standard formula : y = ax</span>² + bx + c ; -(b/2a) is the x-coordinate of the vertex. Substitute the value of x to find the value of y.
