Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 =
(140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
Answer:
We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)" or the standard normal table
We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)" or the standard normal table.
We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)" or the standard normal table
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
