Answer:
add up the numbers and divide by the counting of the numbers. so the answer will be 56/7 equal to 8
Answer: the fox runs faster
Rabbit 35/h
Fox 21/1/2
so if we just add 21 again we’ll get 42/h
In Binomial distribution, the expected value or mean is given by,
E(X) = np
where, p = probability of success and n=number of sample size.
E(X) = 100×0.4 = 40
If BD = 12x + 36
And BD = BC +CD = 3 + 1 = 4
BC = (12x + 36)/4 x 3
= 12(x+ 3) /4 x3
= 3(x+3) x 3
= 9x + 27
Likewise,
FE = 12(x + 3) /3 x 1
= 4x + 12
Area = 1/2 x (BC + FE) x DE
= 1/2 x (9x + 27 + 4x + 12)x (x+1)
= 1/2 x (13x + 39) x (x +1)
= 1/2 x 13x2 + 52x + 39
Hope this helps,
