Answer:
C. 4.3
Step-by-step explanation:
Given that
n = 17
P = 1/4
Using binomial
Mean = np
Mean = 17 × (1/4)
= 17 × .25
= 4.25
Approximately = 4.3
Answer:
(16,63,65)
Step-by-step explanation:
Well, by trial and error, it turns out that 16²+63² = 65²
So the pythagorean triplet is (16,63,65)
Answer:
0.75
Step-by-step explanation:
Answer:
N = 18
Step-by-step explanation:
The triangles are similar, thus the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
5N = 90 ( divide both sides by 5 )
N = 18
To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³
