Answer:
C. Commutative property of addition
Answer:
0.018 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 60,000 miles
Standard Deviation, σ = 1500 miles
We are given that the distribution of tread life is a bell shaped distribution that is a normal distribution.
Formula:
P(brand will last between 56,850 miles and 57,300 miles)
0.018 is the probability a certain tire of this brand will last between 56,850 miles and 57,300 miles.
Multiples of four:
4, 8, 12, 16, 24, 28, 32, 36
Is 4 a factor of 48?
48/4=12
Yes, so that means 4 is not the answer.
Is 8 a factor of 48?
48/8=6
Yes, so that means 8 is not the answer.
Is 12 a factor of 48?
48/12=4
Yes, so that means 12 is not the answer.
Is 16 a factor of 48?
48/16=3
Yes, so that means 16 is not the answer.
Is 24 a factor of 48?
48/24=12
Yes, so that means 24 is not the answer.
Is 28 a factor of 48?
48/28= irrational number
No, so that means 28 is the answer.
Is 32 a factor of 48?
48/32= irrational number
No, so that means 32 is the answer.
Is 36 a factor of 48?
48/36= irrational number
No, so that means 36 is the answer.
Answer: 28, 32, 36
combine the like terms so 2/3x +1/2x
