Answer:
Step-by-step explanation:
It is possible to obtain a ""quick-and-dirty"" estimate of the mean of a normal distribution from the 50th percentile value on a normal probability plot, because normal distribution curve is symmetrical about its mean with 50% on either side of the mean. Also it is unimodal, with mean = median = mode. Because of symmetrical shape, and other special properties we can obtain estimate of mean as the 50th percentile of any normal distribution.
Also in normal distribution 34% lie between mean and 1 std deviation on right side/left side
This gives 84th percentile is got by taking the z value on right side of mean.
When we subtract 84th percentile value from the 50th percentile value we really get -1 times std deviation. Hence to get std deviation actual value, without negative sign, we subtract (50-34) = 16th percentile from mean.

Step-by-step explanation:
Answer:
Part a) The linear model that shows the salesperson’s total income is equal to
Part b) The total income is 
Step-by-step explanation:
Part a)
Let
k-------> the total sales for the year
y-----> the total income for the year
we know that
The linear equation that represent the situation is
Part b) we have
substitute the value of k in the linear model to find the total income
122.1 or 122
becuase the original answer is 122.13 and the 3 gets out becuase it rounds down and so does the 1
I’m pretty sure you can first do 10% at a time which you can round to 13 which is 3 so 3 plus 3 then add tax
