Find the measurement of HI
Murljashka [212]
Answer: 15

Explanation: the triangle to the right is a dial action of the smaller triangle, therefore the triangles are similar. Since the sides of both triangles are corresponding if the corresponding side to JI is 5, and JI is 25 then it is a dialation by a multiple of 5. So since the corresponding side to HI is 3, HI is 15

REY [17]

Answer:

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
