The constant is a number by itself.....no variables
so the constant in y = 4x - 110 is : -110
5 + (8*y) = h
This was the best I could think of, please let me know if I'm wrong.
You have to solve for F so you need to get it by itself which means it would look like:
9/5C+32=F
Then you plug in 33 for C and solve. When you round to the nearest whole number, you get D. 91
Part a: For variable X using z score you have (x-30)/10, replace X for this expression in (a), i mean Z=2+10((x-30)/10) = 2+x-30= put this in the way of z score = (x-18)/1, so the mean is 18 and standard deviation is 1.
Part b: Z=X+Y= (x-30)/10 + (x-20)/8 = solve adding fractions = (18x-440)/80 now divide all the numbers between 18 (because you need to show as z score way) = (x-24.4)/4.4, so the mean is 24.4 and standard deviation is 4.4.
For part c,do the same.
