The point p(x, y) lies on the terminal side of an angle θ = -60° in standard posistion. what are the signs of the values of x and y?

x positive, y negative

Step-by-step explanation:

-60 is the 4th quadrant of the unit circle ( negative angles go clockwise from 0), so  the x value is positive and the y value is negative.

nswer: a   y-axis

step-by-step explanation:

85.560%

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
