It is number 1 and number 2 because the equation is 242× 62 and Number 1 and 2 are just breaking it down
The cost of old computer is $ 357
<em><u>Solution:</u></em>
Let "x" be the cost of old computer
From given,
Cost of new computer = $ 709
Blairs new computer cost 5$ less than twice the cost of her old computer
Therefore,
Cost of new computer = twice the cost of old computer - 5
Cost of new computer = 2x - 5
709 = 2x - 5
2x = 709 + 5
2x = 714
Divide both sides by 2
x = 357
Thus the cost of old computer is $ 357
Answer:
x < - 3
Step-by-step explanation:
Given
x + 5 < 2 ( subtract 5 from both sides )
x < - 3
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.
Answer:
The answer is 0.000.000.01
