Help me pls i really need some help :)

I'm not sure but from my thinking I think it is 40%

Step-by-step explanation:

I think like this ⬇️

.

100% × [ Number of people for each hair color /25(all people) ]

.

brown hair = 100% × (10/25) = 40%

.

Do the same for the other three hair colors.

.

black = 32%

blonde = 20%

red = 8%

Hope it helps you.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
