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

The  standard score  

The  the percentile  

Step-by-step explanation:

From the question we are told that

   A data value is  0.6 standard deviations above the mean.

The above statement can be mathematically represented as

Where is the standard deviation and   is the mean

   Generally the standard score is mathematically represented as

   =>      

   =>    

Now the percentile is obtained from the z-table , the value is  

=>    

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
