A jar contains 5 pink and 8 navy marbles. A marble is drawn at random. What is the theoretical probability of NOT drawing pink?

1 answer:

3 0

8/13 =0.53 (likely)

8 (navy marbles) over the total amount of marbles = 0.53
0=impossible
between 0 and 0.25 =likely impossible
between 0.25 and 0.50 = less likely
0.50 = equal , even, or same
between 0.50 ans 0.75 = likely
between 0.75 and 1 = most likely
1 = certain

Answer:mkay, also yes he did

Step-by-step explanation:

1.Remove the parentheses

2.put -5z and 4z together which makes -9z(negative plus positive equals negative)

3.-9z+ -6z=-3z and 7+8=15

4.15 decided by -3=5

so yes, z=-5

Slope is defined simply as delta y over delta x or the change in y over the change of x. We need to decided what points is going to be the start or the end. Typically, the point farther to the right of the graph is considered the end point.

Start: (1, 7)

End: (10, 1)

$m = \frac{1 - 7}{10 - 1} \\\\\\m = \frac{-6}{9} \\\\\\m = \frac{-2}{3}$
