F(x) = -5x + 1
f(-2) = -5(-2) + 1
f(-2) = 10 + 1
f(-2) = 11

Answer:
A. The CV is a relative measure of risk/return.
Step-by-step explanation:
The coefficient of variation of any investment, is used to measure and calculate the total risk of that investment with respect to its per unit expected return rate.
We can also define the coefficient of variation as a ratio of standard deviation to the expected value of an investment.
The answer is - A. The CV is a relative measure of risk/return.
"Variability (also called spread or dispersion) refers to how spread out a set of data is. Variability gives you a way to describe how much data sets vary and allows you to use statistics to compare your data to other sets of data. The four main ways to describe variability in a data set are:
<span>Range Interquartile range Variance Standard deviation.
it is hard to explain but i hope this helped:/:)</span>
Answer:
All the coordinates are changed to
(x, y) ⇒ (2x, 2y)
Step-by-step explanation:
Given - A triangle is to be dilated with the origin as the center of dilation and with a scale factor of 2.
To find - Which answer choice correctly maps this dilation algebraically?
Proof -
Let ABC is a triangle where A, B, C are the vertices of the triangle respectively.
Now,
Let the coordinates be (x, y)
If a triangle is to be dilated with the origin as the center of dilation and with a scale factor of a , then the coordinated be changes as
(x, y) ⇒ (ax, ay)
Here given , a = 2
So, all the coordinates are changed to
(x, y) ⇒ (2x, 2y)
