Answer:
-0.48
Step-by-step explanation:
Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y =
or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=
≈ 22.4
Lee's shoe size would be a 9
9 6 6
Range = biggest value - smallest value
9-6 = 3
A) 0.2076
B) 0.6786
C) 0.3214
Explanation:A)

B) We find the probability that X=6, 7, or 8:

C) P(X≤5) = 1-P(X>5) = 1-0.6786 = 0.3214
(x+20)-(x+1)=18
x+20-x-1=18
19=18
It has no solution
