Aset of data is normally distributed with a mean of 52 and a standard deviation of 5. what percentage of the data is in the interval 47-57?

if you mean

then it's c. 8, -7/3

but if you mean

then it is

(- 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 )
