45/15=3, so every 3 students must clean 1 mile. 1/3=0.333 forever. Hope this helps!!!
Answer:
the answer would be 4/4 or 1
Step-by-step explanation:
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.
Answer:
A
Step-by-step explanation:
-(x) so -(12)=-12
(-12,-19)
To find the slope use Y2-Y1/X2-X1.
3-(-5)/1-(-3)
=8/4
=2
the slope of the line is 2.
m=2 plug into y=mx+b
use any set of coordinate points. ill use (1,3)
3=2(1)+b
b=1
SO YES YOU DID IT CORRECTLY!
