<h3>Answer: Second graph</h3>

Why? Because we draw a dashed line through x = -1/2 = -0.5 on the horizontal number line (aka x axis). Then we shade to the right of this dashed line. The shaded region represents all points that make the inequality true. For example, the point (0,0) is in the shaded region. It has an x coordinate of x = 0 which is larger than -1/2

Side note: the dashed line says "points on this boundary do not count as solutions". So any point with an x coordinate of -1/2 does not count.

Fazio chooses a jersey at random and then replaces it. He then selects a second jersey at random. What is the probability that f

Natalka [10]

Answer:

4% probability that fazio selects a striped jersey both times.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem:

For each jersey, there are 2+5+3 = 10 possible options, two of which are striped.

So twice 2/10

$p = (\frac{2}{10})^{2} = \frac{4}{100}$

4% probability that fazio selects a striped jersey both times.

Add 5/9 + 7/12 .Enter your answer below as a fraction in lowest terms, using the

Alexxx [7]

Answer:

1 5/36

Step-by-step explanation:

need a common denominator which would be 36

to get from 9 to 36 you multiply by 4 so 5 would be multiplied by 4 to get the fraction 20/36

do the same with 7/12 12x3 is 36 and 7x3 is 21 so 21/36

then add 20+21=41

put over 36 41/36

Find if you can lower it which you can:

41 is bigger than 36 by 5 so your ending fraction would be 1 and 5/36 because 5 and 36 don't have a common factor.
