1 answer:
Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls
= 14

Answer:
f(x)=5x^3-2x^2-90x-36=0
=x^2(5x-2)-18(5x-2)=(x^2-18)(5x-2)=0
x^2-18=0/5x-2=0
x^2=18=x=9√2
5x-2=0
x=2/5
zeros are 9√2,2/5
