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.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
