For quite some time now, calculators have had statistical functions built in. Here we need to use the stat. function normalcdf, which has only two inputs when we're working with z scores instead of raw scores.
Here,
normalcdf(-100,1.25) = 0.894
This same result could be obtained using a table of z-scores.
Answer:
from those are similar, the ratio of side will be 40/24=x/20 so x=33.3333 is equal 33 and one-third.
Y = x - 1
y = -5 - 1
y = -6
(x, y) = (-5, -6)
y = x - 1
y = -3 - 1
y = -4
(x, y) = (-3, -4)
y = x - 1
y = 0 - 1
y = -1
(x, y) = (0, -1)
y = x - 1
y = 1 - 1
y = 0
(x, y) = (1, 0)
y = x - 1
y = 2 - 1
y = 1
(x, y) = (2, 1)
Answer:
you're correct on the first one, and the second one is 8.
