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
Answer:
Step-by-step explanation:
Given point doesn't satisfy the inequality
Step-by-step explanation:
In order to check, if an inequality is satisfied by the point or not the point is put in the inequality
Given inequality is:
Putting the point (-2,-1) in the inequality
As -6 cannot be greater than zero,
So,
Given point doesn't satisfy the inequality

Answer:
The constant of proportionality is 12.
Step-by-step explanation:
Let's take a look at the formula give to us:
48=4k
First, we have to isolate the variable, K, by dividing 4 on both sides.
48/4=4/4 k
48/4=12
12=k
We can check the answer by plugging it back into the equation:
12*4=48
48=48
Hence, the variable k equals 12.
