Suppose S and T are mutually exclusive events. Find P(S or T). P(S) = 20%, P(T) = 22%
Svetradugi [14.3K]
S and P are mutually exclusive events.
P ( S ) = 20% = 0.20
P ( T ) = 22 % = 0.22
The probability of mutually exclusive events:
P ( S or T ) = P ( S ) + P ( T )
P ( S or T ) = 0.20 +0.22 = 0.42
Answer: The probability of ( S or T ) is 0.42 or 42 %.

Write an  equation of the line that passes through please (2, -2) and is parallel to line y=3x+9
gayaneshka [121]

Answer: y=3x-8

Step-by-step explanation:

To find the parallel line, you know that the slope must stay the same. If the slope is different, the graphs will touch at one point. This goes against parallel lines as they NEVER touch or cross.

y=3x+b

We can use the given point to find the y-intercept.

-2=3(2)+b             [multiply]

-2=6+b                  [subtract both sides by 6]

b=-8

Now that we have found the y-intercept, we can finish our equation.

y=3x-8

The +7 is the y-intercept

It is where the line starts in your example and is 7 units away from 0

Since the line is decreasing the 3 is negative
