Amelia surveyed 80 students at her school about their favorite subjec. Of those surveyed, 5 chose math as their favorite subject. If there are 750 students in the whole school, around how many like math?

46.875, or around 47.

Step-by-step explanation:

first, we find the percentage of the 5 from the 80.

we simply divide 5/80, which equals 0.0625, or 6.25%.

Alright, so now we know that 6.25% of 80 is 5.

lets find 6.25% of 750.

to get that we just multiply 750 by 0.0625, which gives us 46.875.

Hope this helps

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
