Answer:
The probability is 1/18.
Step-by-step explanation:
There are 10 balls in total. Let's start with the probability of just the green. There is 1 green ball.out of 10 balls total, so the probability of pickin just the green one would be 1/10. Since we aren't replacing the balls after we choose them, the total number of balls is now 9. now the probability of picking one yellow ball out of the nine balls left is 5/9 because there are 5 yellow balls. To get the probability of the green and yellow balls picked, we multiply the individual probabilities to get the actual probability of choosinf one green and one yellow ball without replacement. So multiply 1/10×5/9= 5/90, simplified to 1/18.
The answer i came up with is : (4b-7x) (a+2)
Assuming Lindsey takes 5 hours to mow a lawn, she earns from twelve lawns
12*70=$840.
If the above assumption is not correct, @funnyork2005 needs to clarify the question.
Answer:
Step-by-step explanation:
55 is the one time fee so that's your y intercept
0.40 is your slope
so y = mx + b
y = 0.40m + 55
this should be correct, unless you're doing something else.
15 + 17r - 4r - 9 = 9
6 + 13r = 9
13r = -3
r = -3/13
