Find the standard deviation, s, of sample data summarized in the frequency distribution table below by using the formula below, where X represents the class midpoints, F represent the class frequency, and N represents the total number of sample values. Also, compare the computed standard deviation to the standard deviation obtained from the original list of data values, 11.1. interval/ 20-29/30-39/40-49/50-59/60-69/70-79 /80-89/
frequency/ 2/1/2/1/15/38/34/

standard deviation=___

20+ ! come and answer quick! triangle mno is reflected over the x-axis and then translated up 4 and right 3. how can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? a translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis. b translate the pre-image up 3 and right 4 and then reflect the figure over the x-axis. c translate the pre-image up 4 and left 3 and then reflect the figure over the y-axis. d translate the pre-image down 3 and right 4 and then reflect the figure over the x-axis.

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2

Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x
