Nati randomly selected 10 girls and 10 boys from her 7th grade class and recorded their heights in inches. the results are shown. girls: 61, 58, 63, 57, 58, 59, 62, 60, 64, 56 boys: 58, 55, 63, 60, 58, 65, 60, 57, 63, 62 a. find the mean and median of the girls’ heights. show your work.

Mean= 59.8 and median = 59.5

Step-by-step explanation:

Mean  = Summation of values/ No. of Values

Mean of Girls' height= 61+58+63+57+58+59+62+64+60+56/10

Mean=  598/10= 59.8

Arranged Data = { 56, 57,58,58,59, 60, 61,62,63,64}

As the number of observations is even so the 5th and 6th value will be added and divided by 2

59+60/2= 59.5

Median = 59.5

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
