Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
Given that,
We have to find are we extrapolating or interpolating when we use a least-squares line to forecast y values for x values outside the range of x values seen in the data.
Option A) We are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
<h3>What is extrapolation?</h3>
Extrapolation is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable.
Therefore, Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.

Answer:
After 200 students, it would better to hire Band A
Step-by-step explanation:
350+ 1.25x = 600
1.25x = 250
x = 200
at 200 students the cost is the same for Band A and Band B
at 201 students Band A will be cheaper then Band B
Answer: A he was determined and hard working
Step-by-step explanation:
"ug" stands for microgram. You can convert microgram into grams by multiplying a certain factor. For this case, 1 microgram is known to be 1x10^-6 g. This is the conversion factor that will be multiplied to 3.54.
3.54 ug ( 1x10^-6 g / 1 ug ) = 3.54 <span>x10^-6 g</span>
