Triangles ALWAYS measure 180 degrees.
78 + 23 = 101
180 - 101 = 79
The measure of the other angle is 79 degrees.
Hope this helped
The slope intercept form is y=mx+b
in this case y=-x
y=(-1)x + 0
so the slope m=-1 and y-intercept which is b is 0
Answer:
And we can find this probability with the complement rule:
And we can use excel or the normal standard table and we got:
So then we expect about 81.8% of students that will be promoted
Step-by-step explanation:
Let X the random variable that represent the scores of promotion of a population, and for this case we know the distribution for X is given by:
Where and
We want to find the following probability:
And we can use the z score formula given by:
Using the z score formula we got:
And we can find this probability with the complement rule:
And we can use excel or the normal standard table and we got:
So then we expect about 81.8% of students that will be promoted
We would cassify -9 as a negative number, whole number, and an integer.
A negative number is a number with a "-" before it.
An integer is a whole number.
Best of Luck!
The equation of the line passing through the points and is
Then
1) the equation of line A is
2) the equation of line B is
Since then lines are not perpendicular.
Since then lines are not parallel.
Answer: neither parallel, nor perpendicular
