Find the measure of each angle in the triangle.

Answer:
Each angle measures 25, 70 and 85
Step-by-step explanation:
The sum of measures of the interior angles in a triangle is 180 degree
So to find out the value of x we add all the interior angles and set it equal to 180 degree
combine like terms
Subtract 30 from both sides
Divide both sides by 6
x= 25
Now we plug the value of x and measure each angle

Answer:
0.674
Step-by-step explanation:
If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is
and its cumulative distribution function (CDF) is
So, <em>the probability that X is less than 28 minutes is </em>
Answer:
Option C. The open and closed circles are reversed and the graph shifts up.
Step-by-step explanation:
From the graph of the functions (Attached below) you can check that for the interval 0 ≤x<1 the floor function takes the value 0 everywhere, also it has closed brackets at 0 and open brackets at 1.
On the other hand for the interval 0<x≤1 the ceiling function takes the value 1, also it has open brackets at 0 and closed brackets at 1.
For that reason we conclude that the open and closed circles are reversed and the graph shifts up.
