A tire manufacturer believes that the life of its tires follow a normal distribution with a mean of 46,000 miles and a standard deviation of 4,000 miles. What mileage can he guarantee each tire to last so that 99% of the tires last longer than the guaranteed lifetime?
Answers
Answer:
Guarantee of Tyre = 36,680 miles
Step-by-step explanation:
Given:
Mean = 46,000 miles
Standard deviation = 4,000 miles
Computation:
Assume;
x = guaranteed lifetime
P(X > x) = 99%
So,
P(X > x) = 0.99
So,
P(Z > z) = 0.99
So,
1 - P(Z > z ) = P(Z < z)
P(Z < z) = 0.01
So, in z table value of z = -2.33
x = μ + [z x σ]
x = 46,000 + [-2.33 x 4000]
x = 36,680
Guarantee of Tyre = 36,680 miles

The solution to the system of equations shown is (2, 0).3x − 2y = 6x + 4y = 2When the first equation is multiplied by 2, the sum of the two equations is equivalent to 7x = 14.Which system of equations will also have a solution of (2, 0)?6x - 4y = 6x + 4y = 26x − 4y = 62x + 8y = 2x + 4y = 27x = 146x − 4y = 67x = 14

Tia dilated the rectangle below by a scale factor of 7/2. What is ther perimeter of the new rectangle?
A
64 inches
B
220 inches
C
2695 inches
D
224 inches
Answers
Answer:
Option D
Step-by-step explanation:
Formula to be used,
Scale factor = [tex]\frac{\text{Dimension of the image rectangle}}{\text{Dimension of the original}}[/tex]
By this formula,
[tex]\frac{7}{2}=\frac{\text{Length of the dilated rectangle}}{\text{Length of the original rectangle}}[/tex]
[tex]\frac{7}{2}=\frac{L}{22}[/tex]
L = [tex]\frac{7\times 22}{2}[/tex]
= 77 inches
Similarly, width of the the dilated rectangle = [tex]\frac{7}{2}\times 10[/tex]
= 35 inches
Perimeter of the new rectangle = 2(Length + width)
= 2(77 + 35)
= 224 inches
Option (D) will be the correct option.
