Answer:
it's Reflected then translated
Step-by-step explanation:
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.
Answer:
14 mm
Step-by-step explanation:
perimeter of a square is a + b
and all sides are equal to each other since its a square
therefore it is 14 mm each
Answer:
Its C because if she found the y value she needs to find the x and she plugged in the y value for x.
