Answer:
Step-by-step explanation:
P = 3,000
r = 5% = 0.05
t = 9 years
Amount after 9 years is
A = P (1+ r)^t
A = 3,000(1+ 0.05)^9 = 3,000 * 1.05^9 = 4653.984648 ≈ $4,653.98
The balance after 9 years, rounded to the nearest cent is
$4,653 and 98 cents
Answer:
a) How many African-Americans would you expect to get promotions?
Since we have been asked to follow the binomial distribution, (B (40,0.2)
To calculate the mean of the BPD = n*p
where n is the number of promotions and p = probability
= 40 x 0.2 = 8
You expect 8 promotions.
b)
The probability that 5 African-Americans = P (X = 5)
P( X = 5 ) = 40 sqr root ( 5 * 0.2^5 * 0.8^35 ) = 0.0854
c) What is the probability that five or fewer African-Americans receive promotions?
P( X <= 5) = P(X=5) + P(X=4) + ... + P(X=1) + P(X=0)
faster way is calculator
binomcdf(40, .2, 5) = 0.1613
