(co 1) what is the standard deviation and its meaning given this population of customer ages? 45, 76, 30, 22, 51, 40, 63, 66, 4116.5 which means that many of the ages will be around this value17.5 which means that many of the ages will be around the square of this value16.5 which means that many of the ages will be within this value of the average age17.5 which means that many of the ages will be within this value of the average age

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

a: inscribed angles

step-by-step explanation:

i reviewed this question with a peer and teacher, seems to be correct, me later

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
