Answer:

Step-by-step explanation:
The parent function is

First it is asked to reflect over the y axis so using the rule

Our function looks like

Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule

When subtracting a 7 it looks like now
where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule

where a is the vertical stretch. So now it would look like

The answer would be 1.40. The 3 significant figure are 1.39 and it wants us to round so we look at the 8 in 1.3981 and since 8 > 5 we know to round up.
The easy way is just to divide by 3
15% /3 = 5%
Since you have divided the % by 3 you can divide the 375 by 3
375 / 3 = 125
Answer 125
A <em>parameter </em>is a number describing a whole population (e.g., population mean), while a <em>statistic </em>is a number describing a sample (e.g., the sample mean).
