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.
Area = (side length)^2
Here,
64n^36 = s^2. Take the sqrt of both sides, obtaining 8n^18 = s. This is the principal square root. We use this positive quantity because the measure of side length must be positive.

Answer:
y = x
Step-by-step explanation:
The equation for slope is y = mx +b. If you look at the line you see that it passes through the origin, this is your y-intercept, 0. If you look at two points at the line and use the rise over run method, you get the slope to be 1. If you substituent these values into the equation you get, y = x.
Hope this helps!

Answer:
1260 degrees
Step-by-step explanation:
the degree of one interior angle is 108 degrees, therefore the exterior angle is 252 degrees. there are 5 interior angles, so there are 5 exterior angles. 252*5=1260 degrees
