For the given data value, find the standard score and the percentile. A data value 0.6 standard deviations above the mean.

The z-score is

The percentile is  

Step-by-step explanation:

From the question we are told that

   The  data value is  0.6 standard deviations above the mean i.e  

Where   is the population mean and is the standard deviation

Generally the z-score is mathematically represented as

=>    

=>    

The percentile is obtained from the z-table and the value is

=>  

55/i dont know i do it for the points

step-by-step explanation:

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
