Whats wrong with my answers?

$y=0.5x-2\implies y=\cfrac{x}{2}-2\implies \stackrel{x-intercept}{0=\cfrac{x}{2}-2} \\\\\\ 2=\cfrac{x}{2}\implies 4=x\qquad \qquad \boxed{(4~~,~~0)} \\\\\\ \stackrel{y-intercept}{y=0.5(0)-2}\implies y=-2\qquad \qquad \boxed{(0~~,~~-2)}$

77b)

$y=-0.4x+2\implies y=-\cfrac{4x}{10}+2\implies y=\cfrac{2x}{5}+2 \implies \stackrel{x-intercept}{0=\cfrac{2x}{5}+2} \\\\\\ -2=\cfrac{2x}{5}\implies -10=2x\implies \cfrac{-10}{2}=x\implies -5=x~\hfill \boxed{(-5~~,~~0)} \\\\\\ \stackrel{y-intercept}{y=-0.4(0)+2}\implies y=2\qquad \qquad \boxed{(0~~,~~2)}$

Apples are in 1/4 of all the lunch bags that are distributed at a school picnic, and bananas are in 1/3 of the bags. What is the

horsena [70]

Answer:

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana

Step-by-step explanation:

We have these following probabilities:

1/4 probability that a lunch bag contains an apple.

1/3 probability that a lunch bag contains a banana.

What is the probability of randomly choosing a lunch bag that contains either an apple or banana?

$P = \frac{1}{4} + \frac{1}{3} = \frac{3 + 4}{12} = \frac{7}{12}$

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana
