Answer:
1.4
Step-by-step explanation:
Probability of selecting a red counter :
Number of red counter / total number of counters
5 / (5 + 3) = 5 /8 = 0.625
Probability of selecting a blue counter = 0.375
Let number of red counters :
0, 1 or 2
0 red counters :
Expected value = x * p(x)
0 + (0.625*1) + (0.390625 * 2)
0 + 0.625 + 0.78125 = 1.40625
Expected number of red counters = 1.4
2 cases x 12 cans = 24 cans
24 cans x 54 oz per can = 1296 oz
1296 oz / 6 oz per serving = 216 guests served
Answer:
$711.23
Step-by-step explanation:
We assume the entire closing cost went to reducing the principal of the loan. Then the amount borrowed was $147,192.
<h3>Monthly payment</h3>
The amortization formula tells you the monthly payment.
A = P(r/12)/(1 -(1 +r/12)^(-12t))
P is the principal, r is the annual rate, and t is the number of years.
The monthly payment is ...
A = $147,192(0.041/12)/(1 -(1 +0.041/12)^-360) ≈ $711.23
Jeff's monthly payment is $711.23.
Formula: V = PI x r^2 x H
Volume = 3.14 x 4^2 x 10
Volume = 3.14 x 16 x 10
Volume = 3.14 x 160
Volume = 160π or 502.4 units^3
The answer to the question is D
