The goal for the size of the Santa on a Christmas Santa cup is 3.5 cm (T) with an acceptable tolerance of ± 0.9 cm. The grand mean of the size of the Santa from the samples that were taken is 3.4 cm (m) and the standard deviation is 0.28 cm. What is CPk? (rounded to three decimals

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
