Answer:

see explanation

Step-by-step explanation:

To begin with find g(f(x)) by substituting x = f(x) into g(x)

g(2x + 5) = (2x + 5)² = 4x² + 20x + 25

Now substitute x = g(f(x)) into h(x)

h(4x² + 20x + 25) = - 2(4x² + 20x + 25) = - 8x² - 40x - 50, hence

h(g(f(x))) = - 8x² - 40x - 50

The following table shows the number of hours some students in two neighborhoods spend walking to school each week:

AlexFokin [52]

Neighborhood A :
first, put the numbers in order...
2,[2,2],4,(4),5,[5,5],5

5 number summary :
minimum = 2
Q1 = 2
Q2 (median) = 4
Q3 = 5
maximum = 5
IQR = Q3 - Q1......5 - 2 = 3...so the IQR = 3

Neighborhood B :
1,[1,2],2,(3),4,[5,5],12

5 number summary :
minimum = 1
Q1 = (1 + 2) / 2 = 3/2 or 1.5
Q2 (median) = 3
Q3 = 5
maximum = 12
IQR = Q3 - Q1....5 - 1.5 = 3.5

are the box plots symmetrical ?

Neighborhood A : the median is 4.....the minimum is 2....so thats 2 spaces from the median...the maximum is 5....so thats 1 space from the median...and being that they are not the same distance from the median, ur box plot is skewed to the left...so this is not symmetrical

Neighborhood B : the median is 3....the minimum is 1....so thats 2 spaces from the median...the maximum is 12....so thats 10 spaces from the median....these are not symmetrical especially since u have an outlier of 12....this is skewed to the right
