The weekly mean income of a group of executives is $1,000 and the standard deviation of this group is $100. the distribution is normal. what percent of the executives have an income of $925 or less? group of answer choices

Approximately 23 percent of the executives have an income of $925 or less

Step-by-step explanation:

Given -

Mean income  =  $1,000

Standard deviation = $100

Let X be the income of group of executives

what percent of the executives have an income of $925 or less =

= )

                   =        Put [   ]

                     =     Using Z table      

                    =  .2266

                     =

                     =   (Approximately)

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

7,24
