Answer:
Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 27,000 miles
Standard Deviation, σ = 2100 miles
We are given that the distribution of life expectancy is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.10
Calculation the value from standard normal z table, we have,
Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
How many 5-digit numbers can be formed using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, if repetitions of digits are allowed?

50 different 5-digit numbers because it would be 5x10 which equals 50.
The answer to this problem situation would be D.
To solve this problem you would simply divide 1 by 6 (the line between the 1 and 6 in the fraction is a division sign with the denominator always out and the numerator in)
1) 1÷6= 0.1666666666667
Now you traditionally and usually would round up but if the direction says otherwise then round down.
2) 0.17
And 0.17 would be your final answer!
The steps to draw all the three angles have been explained.
<h3>What is an Angle ?</h3>
An angle is made by two rays that have one common end point known as vertex.
To make an angle congruent to the one given , the angle has to be copied
For making both ∠XYZ and∠ UVW , following steps will be followed.
- Draw two rays separately and name it YZ and VW .
- Take a compass and draw a free hand arc from the point B and E and with the same measure draw a free hand arc from the point Y and V respectively.
- Take the compass to the angle ABC and DEF again , from the point where the arc intersects BC and EF , cut an arc on the ray AB and DE .
- With the same measure , keep the compass on the point the free hand arc intersected on the ray YZ and VW , cut the arc by the new arc .
- The point where both the arc intersects will be joined form the end points , Y and V , to form an angle.
- The angle formed will be copy of ∠ABC and∠ DEF
Now to draw RST = ABC + DEF
- Draw the angle ABC and repeat the steps to draw DEF taking , AB ray as the base of the angle.
The angle obtained will be RST.
