There are a total of 5+8+2=15 marbles. There's a 5/15 chance of drawing a red marble in the first trial. Then, there are 4 red marbles and 14 total marbles left, so afterwards, there's a probability of 4/14 that the second marble is red. The probability overall is found by multiplying these together, so the first answer is the best.
There are 2+6+7=15 cakes. There's a 6/15 chance that the first cake selected will be a pineapple cake, and then a 2/14 chance that the second cake selected will be a strawberry cake, by the same logic as above. This is equal to 12/210. The first answer is the best option.
The answer is false. They are the same
Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
First, find slope using the given coordinates. Formula for slope: y₁ - y₂ / x₁ - x₂.
Our coordinates are (-2, 5) and (2, -7). Plug them in and simplify.
5 - (-7) / -2 - 2
5 + 7 / -4
12/-4
-3
The slope is -3. The equation becomes y = -3x + b.
To find b, plug an (x, y) coordinate on the line in for x and y in the equation and solve. I'll use (-2, 5)
y = -3x + b
5 = -3(-2) + b
5 = 6 + b
-1 = b
The y-intercept is (0, -1). The equation can now be completed!

Answer:</h3>
y = -3x - 1
Answer: <em>C</em>
Step-by-step explanation:
<em>In 2 games the team had </em><em><u>zero</u></em><em> runs</em>
<em>In 1 game the team had </em><u><em>one</em></u><em> run</em>
<em>In 1 game the team had </em><em><u>two</u></em><em> runs</em>
<em>In 3 games the team had </em><em><u>three</u></em><em> runs</em>
<em>In 2 games the team had </em><em><u>four</u></em><em> runs</em>
<em>In 1 game the team had </em><em><u>five</u></em><em> runs</em>
Y=1
Explanation:
You have to plug 2+x into the y of the first equation. After you solve that you should get-1 as the answer for x so you plug -1 into the x of the second equation and the value of y would be 1.
