The value of x is: 75°
360° - 128° - 85° - 72° = 75°
Answer: 2.28%
Step-by-step explanation:
μ = 71.8
σ = 3.4
X < 65
P(X < 65) = P (Z < 65 - 71.8/3.4) = P (Z < -2)
According to the table for the normal distribution attached, it will give us
P (z < Z < 0), this way, to find the P(Z < z), we need to do 0.5 - P:
0.5 - P(-2 < Z < 0) = 0.5 - 0.4772 = 0.0228
In percentage: 0.0228*100 = 2.28%
Answer: least : -1/4 middle: -0.15 greatest: -0.6
if it’s incorrect change places with the 1/4 or 0.15
Answer:
F=$3810
Step-by-step explanation:
F= future value
P= present value
i = interest
n= number of times money compounded
P=$3000 i=6% n = 2 X 4= 8
As this is semiannual so 6%/2=3%
