Step-by-step explanation:
The formula for percent change is
change/original.
So let's subtract 17 from 55 to find the change. 55-17=38
This is the change. Now we divide it by the original, 17.
38/17=2.235294
We're not done yet! We have to move the decimal point over to the right 2 spaces to make it a percentage. So, the percentage increase is
about 223.53 percent
Reference to a standard normal distribution table shows that for a cumulative probability of 0.6064 the z-score is 0.27.
It would be: 5.5 * 10⁵ * 23000
= 5.5 * 10⁵ * 2.3 * 10⁴
= 12.65 * 10⁹
= 1.265 * 10¹⁰
In short, Your Answer would be Option B
Hope this helps!
