Find the range and standard deviation of the set of data.
46, 44, 49, 39, 48, 40, 42

Step-by-step explanation:

The range of a data set is the difference between the least number and highest number in the data set.

The least number in the data set is .

The highest number in the data set is .

So,range is

Standard deviation measures how spread out the values in a data set are around the mean.

Let be the mean of the set.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
