A: a flow chart would best describe the steps
The first one is 13 points and the 2nd one is 8. I'm pretty sure, hope this helps! :)
Answer:

If we solve for k we can do this:




So then we have at last 75% of the data withitn two deviations from the mean so the limits are:


Step-by-step explanation:
We don't know the distribution for the scores. But we know the following properties:

For this case we can use the Chebysev theorem who states that "At least
of the values lies between
and
"
And we need the boundaries on which we expect at least 75% of the scores. If we use the Chebysev rule we have this:

If we solve for k we can do this:




So then we have at last 75% of the data withitn two deviations from the mean so the limits are:


Answer:
g(x)=(x+7)^2-3
Step-by-step explanation:
Given:
f(x)= x^2
Now we have to translate f(x) 7 units to the left and 3 units down to form the function g(x).
As per the rules of translation
when any parent function, in given case f(x)=x^2, is translated to 'a' units to the left then 'a' is added to the value of x. thus making f(x+a)
Also when the parent function is translated any 'a' units down then 'a' is subtracted from the value of function. thus making f(x)-a
Translating f(x), 7 units to the left
f(x+7)= (x+7)^2
Translating f(x+7), 3 units down
f(x+7)-3 = (x+7)^2-3
Hence new function g(x)=(x+7)^2-3!
