Isaac records the following temperatures (in degrees Fahrenheit) at noon during one week: 87, 88, 84, 86, 88, 85, 83

These temperatures do not contain an extreme value.

Which measure of center should Isaac use to describe the temperatures?

A.
Interquartile range

B.
Mean absolute deviation (MAD)

C.
Either the mean or the median. The values are about the same.

D.
Range

please help. im new to , but i will upvote you

first, we put them in order

78,[80],83,(85),86,[87],90

Q1 = 80

Q2 (median) = 85

Q3 = 87

Interquartile range (IQR) = Q3 - Q1 = 87 - 80 = 7 <==

Hope this helps!

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
