If X is a random variable representing the number of children that end up having light-colored eyes, then X follows a binomial distribution with success probability p = 0.25 and number of trials n = 5.
The variance of a binomial distribution with these parameters is n p (1 - p), so the variance in this case would be
5 • 0.25 • (1 - 0.25) = 0.9375 ≈ 0.9
 
        
             
        
        
        
Answer:
d
Step-by-step explanation:
if x has to be greater than -15 and -20 = x than its not true because -20 isn't greater than -15

Amount =$48003.20
Step-by-step explanation:
Here apply the compound interest formula;

where;
P=Principal amount invested = $37500
r=rate of interest as a decimal, 2.5% =0.025
n=number of compounding per year=1
t=time period the amount in invested=10
In our case, the amount after investing will be;

Interest earned after the period= $48003.20-$37500 =$10503.20

Answer:
5/24 or 20.8%
Step-by-step explanation:
  
Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2
  
Probability that the 8th grader is a boy = 5/(5+7) = 5/12
  
Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%
