Answer:
4.5 cm
Step-by-step explanation:
Circunference = 2π*radius = 2*3.14*radius = 6.28*radius = 28.26
so radius = 28.26/6.28 = 4.5 cm
Answer:
x = 
or 
Step-by-step explanation:
Answer:
10^-5 or 1/100,000
Step-by-step explanation:
That probability of 5 events in a row is the 5th power of the probability of one of them, assuming they are independent.
0.1^5 = (10^-1)^5 = 10^-5
Let, the number of weeks = x
It would be: 17 + 11x ≥ 72
Subtract 17 from both sides,
11x ≥ 55
Divide by 11,
x ≥ 5
So, at-least he needs 5 weeks for that
