Answer:
16c^2+56c+49
Step-by-step explanation:
(4c+7)^2 means (4c+7)(4c+7)
Use foil to multiply: 4c(4c)+4c(7)+7(4c)+7(7)
Simplifying : 16c^2+28c+28c+49
16c^2+56c+49
Answer:
The percentage of samples of 4 fish will have sample means between 3.0 and 4.0 pounds is 66.87%
Step-by-step explanation:
For a normal random variable with mean Mu = 3.2 and standard deviation sd = 0.8 there is a distribution of the sample mean (MX) for samples of size 4, given by:
Z = (MX - Mu) / sqrt (sd ^ 2 / n) = (MX - 3.2) / sqrt (0.64 / 4) = (MX - 3.2) / 0.4
For a sample mean of 3.0, Z = (3 - 3.2) / 0.4 = -0.5
For a sample mean of 3.0, Z = (4 - 3.2) / 0.4 = 2.0
P (3.2 <MX <4) = P (-0.5 < Z <2.0) = 0.6687.
The percentage of samples of 4 fish will have sample means between 3.0 and 4.0 pounds is 66.87%
Answer:
$5,788.13
Step-by-step explanation:
For any amount p , if rate of interest is r% yearly
its value after time t years is given by
value after t years = p(1 + r/100)^t
__________________________________
given
p = $5000
r = 5%
t = 3 year
balance after t years = 5000( 1 + 5/100)^3 = 5000(21/20)3
balance after t years = $5,788.13 (answer)
