he events are not independent

<h3>How to determine if they are mutually exclusive?</h3>

The given parameters are:

P(A) = 0.2

P(B) = 0.2

The events are mutually exclusive.

So, as have

P(A or B) = P(A) + P(B)

If the events are independent, then

P(A and B) = P(A) + P(B) - P(A or B)

P(A and B) = P(A) * P(B)

So, we have

P(A and B) = 0.2 + 0.2 - 0.2 - 0.2 = 0

P(A and B) = 0.2 * 0.2 = 0.04

The above equations are not equal

Hence, the events are not independent

What’s the slope of x+2y=-8?
mash [69]

Answer:

- 1/2

Step-by-step explanation:

We use the slope-intercept form to figure out our slope.

y = mx + b

Get y alone:

x + 2y = -8

2y = -x - 8

y = -x/2 - 4

Since m is the slope in y = mx + b, we can see that -1/2 is in the place of m, therefore our slope is -1/2
