Answer:
Step-by-step explanation:
a) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.8 and P(A)=0.2
Hence A and B are not independent.
b) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.6 and P(A)=0.3
Hence A and B are not independent.
c) If events A and B are independent we have
P(A/B) =P(A)
Jere P(A/B) = 0.5 and P(A)=0.5
Hence A and B are independent.
First you need to find the slope of the line containing those 2 points using the slope formula. Filling in with our info we have

. So the slope is -1.5. Now we need to find out the rest of the info, mainly the y-intercept. The line appears to go through the y axis at (0, 0), but let's make sure. We will use the slope we just found and one of our points to solve for the y-intercept. I picked point (4, -6). Filling in to solve for b we get -6 = (-1.5)(4) + b. Doing the multiplication on the right gives us -6=-6 + b. Add 6 to both sides to get that b = 0. Now let's use that and the slope we found to rewrite the equation in slope-intercept form. y = -1.5x + 0 or y = -1.5x and there you go!
Step-by-step explanation:
2a = 10 because a = 5 and 2a means 2 × a which is the same as 2 × 5 and this equals 10.
