Answer:
Step-by-step explanation:
According to the given question, a tire company has developed a new type of steel-belted radial tire. Extensive testing indicates the population of mileages obtained by all tires of this new type is normally distributed with a mean of 37,000 miles and a standard deviation of 3,887 miles.
Let us define X be the random variable shows that the mileages tires normally distributed with
mean
μ = 37000
standard deviation
σ
=3, 887
Therefore
X ~ (μ = 37000, σ =3,887)
The company wishes to offer a guarantee providing a discount on a new set of tires if the original tires purchased do not exceed the mileage stated in the guarantee. Therefore the guaranteed mileage be if the tire company desires that no more than 2 percent of the tires will fail to meet the guaranteed mileage is determined as:
P(X < k) = 0.02

From the standard normal curve 2% area is determined as -2.0537 and hence
If we consider z value at two decimal places then

Therefore the guaranteed 29032 mileage be if the tire company desires that no more than 2 percent of the tires will fail to meet the guaranteed mileage.
The area under the standard normal curve is determined as:
To classify the angle of a triangle (acute, obtuse, or right), you can use slope formula to see if the slopes are perpendicular. If so, it is a right triangle. The distance formula can be applied to figure out whether the triangle is isosceles, equilateral, or scalene. if the triangle is isosceles, then two of the sides will be the same length and one side will be of a different length. If the triangle is equilateral, then all sides will be of the same length. If the triangle is scalene, then all side will be of different lengths.
Your equation should be:
4 + 6x = 22
This is so because he only bought one movie, but he bought "some" video games. The variable x represents some in the problem.
Solve the equation.
4 + 6x = 22
Subtract 4 from both sides of the equation.
6x = 18
Divide both sides by 6.
x = 3
Marcus rented 3 video games.
Solution :
D. 4 + 6x = 22
B. 3 video games
Answer:
6.4
Step-by-step explanation:
Find measurement of leg using pythagorean theorem
b^2 = c^2- a^2
b^2= 13^2 - 4^2
b^2= 169-16
b^2= 153
b= 12.4
t+6= 12.4
subtract 6 from both sides
t= 6.4
