Answer:
A) 3.5
B) 1.6202
Step-by-step explanation:
In binomial distribution,
E(X) = np and Var(X) = npq while
SD (X) = √(npq)
Where n is number of cards drawn
p is probability of getting one particular shape
q = 1-p
So from the question, n = 14
p = 13/52 = 1/4
q = 1-(1/4) = 3/4
So;
A) E(x) = np = 14 x 1/4 = 3.5
B) SD (X) = √(npq) = √(14 x 1/4 x 3/4) = √(42/16) = √2.625 = 1.6202
The area of the trapezoid would be 5/8 ft squared.
Answer:
Step-by-step explanation:
Let one no. =x
Therefore,other no. =x-7
According to question,
x+x-7= -23
2x=-23+7
x=-16/2
x=-8
Answer:
5.818 %
