Answer:
None of them are correct because the circumference formula is 2pir
Answer:
You use PEMDAS.
Step-by-step explanation:
If you dont know what that is, its the process used for long multistep equations like that : Parenthesis, Exponents, Multiplication, Division, Addition, then Subtraction. You solve all of those in order (if they are included in the problem). So for this you would solve one side of the inequality sign first using this order, then the other side and BAM! you've solved this problem.
Answer: Choice C) Star shaped symbol
We can rotate the star symbol 90 degrees to have it line up with its original image. The before and after images would be identical after doing such a rotation. So this figure has rotational symmetry.
The other figures would change if we rotated them some angle x such that
, so they do not have rotational symmetry.
Answer:
slope intercept form

Answer: 0.0668073
Step-by-step explanation:
Given : The number of miles each tire lasts before it completely wares out follows a normal distribution with mean μ = 50,000 miles and standard deviation σ = 8,000 miles.
Let x be the random variable that represents the number of miles each tire lasts.
z-score : 
For x= 62,000

By using the standard z-value table , the probability for a randomly selected tire to last for at least 62,000 miles will be :_

Hence, the probability for a randomly selected tire to last for at least 62,000 miles = 0.0668073
