Option C: is the function that represent exponential decay.
Explanation:
The exponential decay can be represented by
where
and
Option A:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option A is not the correct answer.
Option B:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option B is not the correct answer.
Option C:
From the function, we can see that and
Thus, and
Thus, the function represent exponential decay.
Hence, Option C is the correct answer.
Option D:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option D is not the correct answer.
Answer:
Z = -1.65
Step-by-step explanation:
The main objective is to compute the data for the Z value and determine the of the sample distribution
Given that;
the tires' thickness is normally distributed with a mean μ = 0.45 in
standard deviation σ = 0.05 in
sample size = 65 tires
Also; we are being told that the thickness separates the lowest 5% of the means from the highest 95%
∴
P(Z < Z) =0.05
From the Z- table
P(Z < -1.645) = 0.05
Z = -1.65
Similarly;
Let consider to be the sample mean;
Then:
mean
standard deviation
= 0.00620174
By applying the Z-score formula:
x = μ + ( Z × σ )
