3) 5 centimeters
Step-by-step explanation:
Plug 3 and 4 into the formula for the Pythagorean Theorem. You get 5.
There would be 138 students in 6 classes because first you'd divide 207 from 9 and get 23 then you'd multiply 23 to 6 and get 138.
They hiked 2.02 kilometers in all because 1.08 + 0.94 = 2.02
We use the formula 
where d is distance, s is speed and t is time.
Therefore, a car would tracel 480 km.
Answer:
0.1349
Step-by-step explanation:
Given that:
Sample size, n = 500
20% of 500 ; 0.2 * 500 = 100
p = 0.18 ; n = 500 ; 1 - p = 0.82
P(x ≥ 100) ;
Using the binomial probability relation :
P(x =x) = nCx * p(x)^x * (1 - p)^(n - x
P(x ≥ 100) = 500C100 * 0.18^100 * 0.82^400
P(x ≥ 100) = 0.1349
