Heres the answer to number 1 but I can't figure out the rest: A = P(1 + i)^n
A = 2400 , P = 1750 , i = 2.3% , n = ?
2400 = 1750(1 + 2.3)^n
2400 = 1750(3.3^n)
1750(3.3^n) = 2400
1750(3.3^n) / 1750 = 2400 / 1750
3.3^n = 48/35
log(3.3^n) = log(48/35)
n(log(3.3)) = log(48/35)
n = log(48/35) / log(3.3)
<span>n = 0.3</span>

5 Girls + 3 Boys =8 (sample size)
Probability of choosing 1 boy P(1 B) = 3/8
Probability of NOT CHOOSING ANY BOY = 1-3/8 =5/8
Now apply the binomial probability to choose 3 Boys:
8C3(3/8)³(5/8)⁵ ==>P(All boys) = 0.28
If the exponent is positive then you move the decimal to the right to make the number bigger. If the exponent is negative then you move the decimal to the left to make the number smaller.
What are these questions they seem really hard but how do you get ppl to see ur questions nobody helps me
