Answer:
y=41
Step-by-step explanation:
47-6=41
47-41=6
41=y
A^2 + b^2 = c^2
40^2 + x^2 = 48^2
1,600 + x^2 = 2,304
-1,600 -1,600
x^2 = 704
(square both)
x = 26.53....
So the mattress is about 26.5 inches off the ground.

Answer:
B(0.7, 100)
Step-by-step explanation:
Probability of contracting a certain disease = 0.70
No of individual randomly selected = 100
Contracting the disease is a positive/success in this case, hence
p = 0.7 and since there are 100 selection, the binomial distribution B(0.7, 100)
Hence, the The random variable describing the number of individuals who will contract the disease is B(0.7, 100) distribution.
And Mean = 0.7 x 100 = 70
