<h3>Answer: 83.85%</h3>
This value is approximate.
==========================================================
Explanation:
Let's compute the z score for x = 40
z = (x-mu)/sigma
z = (40-47)/7
z = -1
We're exactly one standard deviation below the mean.
Repeat these steps for x = 68
z = (x-mu)/sigma
z = (68-47)/7
z = 3
This score is exactly three standard deviations above the mean.
Now refer to the Empirical Rule chart below. We'll add up the percentages that are between z = -1 and z = 3. This consists of the two pink regions (each 34%), the right blue region (13.5%) and the right green region (2.35%). These percentages are approximate.
34+34+13.5+2.35 = 83.85
<u>Roughly 83.85%</u> of the one-mile roadways have between 40 and 68 potholes.
Answer: Option 'B' is correct.
Our net price will be $3357.21.
Explanation:
Since we have given that
The list price of set of saws = $3800
There are 3 successive discounts :
8%,3%,1%
So, if we apply first for 8% discount our new price becomes,
Now, if we apply 3% on our deducted price , our new price becomes ,
Now, we'll apply for 1% on our new deducted price , our net price becomes,
Hence, our net price will be $3357.21.
Therefore, Option 'B' is correct.
The correct option will be : 14 years
