You have 342 days left of school.
365 - 23 = 342
<span>y-intercept when x = 0
</span>so
y = -7x + 1
y = -7(0) +1
y = 1
<span>B.4/7
You can check by taking 21 * 4/7 = 12 which is figure 2

Answer:
(p green) 1/3
(p red) = 1/2
Step-by-step explanation:
Add the number of balls together to get the total.
3 + 7 + 5 = 15
Find the probability of choosing green.
(p green) = 5/15
reduce by 5
(p green) 1/3
Since you kept the green ball, there are now a total of 14 balls.
Find the probability of choosing red.
(p red) = 7/14
reduce by 7
(p red) = 1/2
