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 %.

Find the midpoint of a line segment with given endpoints (4,-5) and (-6,3)

Mashcka [7]

The equation for the midpoint of a line segment is $( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$ . Thus, the midpoint of this segment is $(\frac{4 + (-6)}{2}, \frac{-5 + 3}{2}) = \boxed{(-1, -1)}$ .

Find the x and y intercepts.

Roman55 [17]

-3/4x + 5/6 y = 15

Multiply through by 6

-9/2x + 5y = 90

Add 9/2x to both sides

5y = 90 + 9/2x

Divide both sides by 5

y = 18 + 9/10x

y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c

Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
