I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)
First I did what’s inside the parentheses, (6x2) and got 12.
Then I divided 16 by 22 and received 0.72.
I added 0.72 with 12 and the result was 12.72.
Last step was to subtract 12.72 - 8 and that equals 4.72
Answer:
Expectation number of books a customer will purchase = 1.3
Step-by-step explanation:
x : 0 1 2
p(x) :0.2, 0.3, and 0.5
Expectation
E(X) = ∑x P(x)
= 0 X 0.2 +1 X 0.3+ 2 X 0.5
= 1.3
Expectation E(X) = 1.3
Expectation number of books a customer will purchase = 1.3
Answer:
174cm^2
Step-by-step explanation:
Given data
L=9m
W=5m
H=3m
The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2
