Answer:
P(X=0) = 0.25
P(X=1) = 0.50
P(X=2) = 0.25
Step-by-step explanation:
The possible outcomes of this event are: BB, BG, GB and GG.
There is one out of four events (GG) in which there are two girls (X=2).
There is one out of four events (BB) in which there are no girls(X=0).
There are two out of four events (GB and BG)) in which there is one girl (X=1).
Therefore, the probability distribution of X is:
P(X=0) = 1/4 = 0.25
P(X=1) = 2/4 = 0.50
P(X=2) = 1/4 = 0.25
Step-by-step explanation:
what huh?????? i dont understand
Let's begin by listing out the information given to us:
Principal (p) = $20,000
Interest rate (r) = 5.2% = 0.052
Number of compounding (n) = 2 (semi annually)
Time (t) = 3 years
The total return is calculated as shown below:
A = p(1 + r/n)^nt
A = 20000(1 + 0.052/2)^2*3 = 20000(1 + 0.026)^6
A = 20000(1.1665) = 23,330
A = $23,330
Answer:
340 people would renew their membership if the gym had 400 members
The gym's claim is not accurate, because the prediction should be 340 people instead of 330
Step-by-step explanation:
With 400 members, we can predict how many will renew their membership by multiplying 400 by 0.85:
400(0.85)
= 340
So, this would predict that 340 people would renew their membership.
The gym's claim that 330 members would renew their memberships is not accurate, because the correct prediction should be 340 people.
