Step-by-step explanation:
Given:
Bryce pays $240,000 for a property, then sells it for 15% less of what he bought is for.
To find:
15% of $240,000 to find the total loss.
__
<h3>steps</h3>
Step 1: Our output value is 240000.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,
Step 4: Similarly,
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives
Therefore,
So if he lost 15% of $240,000, he lost $36,000.
So now we subtract.
240,000 - 36,000
= $204,000
Hence, the total loss of the property was $36,000

Answer:
d. It would become narrower
Step-by-step explanation:
The width of a normal confidence interval is given by:
In which z is the critical value according to the confidence level, is the standard deviation of the population and n is the size of the sample.
W and n are inverse proportional, that is, as n(the sample size) increases, W(the width of the interval) decreases, that is, the interval becomes narrower..
So the correct answer is:
d. It would become narrower
