Answer:
The probability that all will last at least 30,000 miles is 0.3164.
Step-by-step explanation:
Consider the provided information.
For a particular tire brand, the probability of wearing out before 30,000 miles is 0.25. Someone who buys a set of four of these tires,
That means the probability of not wearing out is 1-0.25 = 0.75
Now use the binomial distribution formula.
Substitute p = 0.25, q=0.75, r=4 and n=4
The probability that all will last at least 30,000 miles is 0.3164.
The quotient will be less that 34 because 78 divided by 34 is 2
Answer:
hey
Step-by-step explanation:
hope you having a great day
So a mile has 5280 feet.
21,129/5280= 4 mph
multiply
4 x 2 = 8 miles in 2 hours
Answer:
No, not correct
Step-by-step explanation:
Square pyramid volume: (1/3) (base area)(height). In this case,
V = (1/3)*(12 in)^2*(10 in) = 480 in^3 = 480 in^3
Cylinder volume: (base area)*(height). In this case,
V = (3.14)*(6.77 in)^2*(10 in) = 452.12 in^3.
No, Jude is not correct; the 480 in^3 volume of the square pyramid is not the same as the 452.12 in^3 volume of the cylinder.
