X - Z =
value - mean
Z =
standard deviation
1. The prices of the printers in a store have a mean of $240 and a standard
deviation of $50. The printer that you eventually choose costs $340. Round to
the nearest tenth.
a) What is the z-score for the price of your printer?
b) What does this value mean?

18

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
