Answer:

y-4=-2(x-2) and y=-2x+8

y-4=-2(x-2) is correct because it uses a point given in the correct way and the slope is also correct

2x+y=8 is also correct because it can be converted to slope intercept form as y=-2x+8

First step: Fred has probability of 0,5 when chossing jar 1 or jar 2

Second step : The probability of chossing one chocolate chp cookie in jar 1 is 3/5 and from the jar 2 is 1/2

Then the probability of Fred to get a chocolate chip cookie is

P ( get a chocolate chip cookie ) =( 0.5 * 3/5) +( 0.5* 1/2)

P = 0.3 + 0.25

P = 0.55 or 55 %
