Answer:

The answer is C

Step-by-step explanation:

First you look to the X axis and then the Y, so you found the -3 at the X axis and you look to the Y axis. Then you try and find the 4, so the answer is C. Remember to always look at the X axis first.

A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then
Masja [62]
A.
\frac{7purple}{9total} *  \frac{2white}{8total}  \\  \frac{14}{72}  \\ =0.194
The denominator of the second number goes down one because you aren't replacing the initial marble pulled, making the amount of marbles in the bag go down, but not affecting the white count because you pulled a purple marble.
b.
\frac{2white}{9total} *  \frac{1white}{8total}  \\  \frac{2}{72}  \\ =0.278
The same can be said about the denominator for this problem, but not the numerator. The numerator must go down one number as well, because you already chose one white marble, taking one of the white marbles out of the bag, leaving you with one solitary, white marble.
c.
Chance of selecting two purple marbles:
<u />\frac{7purple}{9total} *  \frac{6purple}{8total}  \\  \frac{42}{72}  \\ =0.583
Chance of selecting two white marbles:
\frac{2white}{9total} * \frac{1white}{8total} \\ \frac{2}{72} \\ =0.278
<u>Chance of selecting two purple</u> vs. <em>Chance of Selecting 2 white:</em>
<u>0.583</u>><em>0.278</em>.
It is more likely to select 2 purple marbles.

Hope this helps!

AHHHHHHHHHH I DON'T LIKE MATH!!!!!!!!!!!!!!!!
REY [17]

Answer:

The answer is 5 1/16

Step-by-step explanation:

3/2 x 3/2 x 3/2 x 3/2

3/2 x 3/2 = 9/4

9/4 x 3/2 = 27/8

27/6 x 3/2 =81/16

Turn 81/16 into a mixed fraction and it’s 5 1/16

Therefore, the answer is 5 1/16

plug in (3,2) to see if it's a solution:

A) does -3(3) + 2 equal -7?    yes

B) since 'A' is a solution then 'B' cannot be the answer

C) since (3,2) is a solution then 'C' cannot be the answer

plug in (2,-1) to see if it's a solution:

plug in (2,-1) to see if it's a solution:

-3(2) - (-1) equal -7?   no, it equals -5

only (3,2) is a solution so the answer is D
