Estimate the slope of the tangent line to each curve at the point (x, y).

I know the answers, I just don't know how to get to the answers

5. 2

7. 1/4

9. 0

7. On the x axis, from -2 to 2 is 4 units

On the y axis at -2 the tangent is at y 2, at x = 2 the line is at about y=3

The slope would be (3-2) / (2 - -2)

Slope = 1/4

9. The line is a straight line so there is no slope. Slope = 0

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
