Subtract 90 from both sides
3x = 144 - 90

Find the probability that first marble picked is green and second marble picked is red.
Write your result as a percentage.
Answers
P(A) = 3/6
(Because the first marble as already been picked there’s 5 marbles left) so:
P(B) = 2/5
Now we have to find the probability of A and B
P(A and B) = 3/6 • 2/5 = 1/5 = 20%
Answer:
20%
Step-by-step explanation:
3 green, 1 brown, 2 red
3 + 1 + 2 = 6
Total: 6
The probability of picking a green one is 3/6 or 1/2.
———————————————————————
2 green, 1 brown, 2 red
2 + 1 + 2 = 5
New total: 5
The probability of picking a red one is now 2/5.
———————————————————————
First, we multiply them by each other.
2/5 x 1/2 = 1/5
Next, we convert 1/5 to a percentage to get our final answer.
1/5 x 20 = 20/100, which is 20%.
So our final answer is 20%.

y = 7/5x - 21/5
Step-by-step explanation:
points to use to find slope: (3,0) and (8,7)
slope = 7-0 / 8-3
slope = 7/5
find y-intercept (or 'b')
0 = 3(7/5) + b

Answer:
x = y = 10
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{10\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
x × [tex]\sqrt{2}[/tex] = 10[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
x = 10
Since the base angles are 45° then the triangle is isosceles and the 2 legs are congruent, then
x = y = 10
The world famous gambler from Philadelphia, Senor Rick, proposes the following game of chance. You roll a fair die. If you roll a 1, then Senor Rick pays you $25. If you roll a 2, Senor Rick pays you $5. If you roll a 3, you win nothing. If you roll a 4 or 5, you must pay Senor Rick $10, and if you roll a 6, you must pay Senor Rick $15. Is Senor Rick loco for proposing such a game? Explain.
Answers
Answer:
You lose $0.833 while Rick gains $0.833, and so Rick is not Loco
Step-by-step explanation:
There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6
Probability of rolling two is 2/6.
Rolling a 1 pays $25, and probability = 1/6
Rolling a 2 pays $5,and probability = 1/6
Rolling a 3 pays $0, and probability = 1/6
Rolling a 4 or 5 pays -$10, and probability = 2/6
Rolling a 6 pays -$15, and probability = 1/6
Thus,lets calculate the expected value;
EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)
EV = - $0.833
This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.

How many turning points are in the graph of the polynomial function?
a.) 4 turning points
b.) 5 turning points
c.) 6 turning points
d.) 7 turning points
Answers
5 turning points are in the graph of the polynomial function.
What are Turning point in graph?Turning points occur when a graph shifts from rising to dropping (rising to falling) or from decreasing to increasing (falling to rising). A polynomial of degree n can turn at most once, or n1.
The point on a parabola where the graph shifts from increasing to decreasing, or from decreasing to increasing, is known as the turning point of a parabola and is also known as the vertex. We refer to a graph as growing when it is rising from left to right.
Turning points are places on a graph where the direction of the line switches from upward to downward.
And from below to above.
We can see that graph is changing its direction at 5 different points and the points are
(-5,6) ,(-3,-3) ,(0.5,0.5) ,(3,2.5) ,(5,5)
Thus, there are 5 turning points.

(x+2)·2x + (x-1)^2= 2 ?
Answers
Answer:
x = 1/3, x = -1.
Step-by-step explanation:
2x(x + 2) + (x - 1)² = 2
Distribute the 2x into x + 2.
2x² + 4x + (x - 1)² = 2
Square (x - 1).
2x² + 4x + x² - x - x + 1 = 2
Combine terms.
2x² + x² + 4x - 2x + 1 = 2
Combine terms again.
3x² + 2x + 1 = 2
Subtract 2 from both sides.
3x² + 2x - 1 = 0
Factor.
(3x - 1)(x + 1) = 0.
Finding the x-values here is the same thing as finding the 0s, so set both of the expressions to 0.
3x - 1 = 0
Add 1 to both sides.
3x = 1
Divide by 3.
x = 1/3.
x + 1 = 0
Subtract 1 from both sides.
x = -1.
