A bag contains nine yellow marbles and nine red marbles. You randomly select two marbles from the bag. What is the probability that both marbles are yellow when you do not replace each marble before selecting the next marble? Write your answer as a decimal rounded to the nearest thousandth.
The probability that both marbles are yellow is about
======================================================
Explanation:
9 yellow
9 red
9+9 = 18 total
If you select a marble at random, the chances of it being yellow are 9/18.
If you selected another marble at random, without replacing the first marble, then 8/17 is the probability of getting another yellow marble. I subtracted 1 from the numerator and denominator of 9/18 to go to 8/17.
We multiply the two results
(9/18)*(8/17) = 0.235 approximately
There's roughly a 23.5% chance of getting two yellow in a row, where we don't replace the first marble selected.
) Three sides of a quadrilateral are the same length, q. The length of the fourth side is 7 inches.
The perimeter of the quadrilateral is 40 inches.
.) Write an equation that represents
the situation.
Write an equation that represents the situation
Answer:
q=(40-7)/3 or simplified q=11
Step-by-step explanation:
So we know that the perimeter is 40 inches and one of the sides is 7 so logically we do 40-7 to get the length of the three remaining sides combined. Then to find the length q, we have to divide that answer by 3 because the three sides have the same length or (40-7)/3, which simplified is 11, so the length of the side is 11 inches and the expression is q=(40-7)/3.

2sin(theta) + 1/sin(theta) - 1
= 0 for 0 <_ x < 2x
Answer:
2 - 2 cos²x = sin x
2 = sin x + 2 cos² x
0 = -2 + sin x + 2(1 - sin² x)
0 = -2 sin² x + sin x + 2 - 2
0 = 2 sin² x - sin x 0 = sin x (2 sin x - 1)
sin x = 0 v sin x = 0.5

How long does it take to pay off the higher-interest card?
What is the amount of the last payment on the higher-interest card? Why?
At the end of the month that you pay off the higher-interest card, after you have started to pay down your debt on the lower-interest card, what is the balance of the lower-interest card? Why?
Complete the following two tables to help you answer questions 4–5.
Rework the problem so that you pay off the lower-interest card first.
How much money do you save by paying off the higher-interest card first?
1. It takes 5 months to pay off the higher-interest card first.
2. The amount of the last payment on the higher-interest card is $232.89. It is the balance plus interest in the fifth month.
3. After paying down the debt on the lower-interest card in the 5th month, the balance of the lower-interest card is $338.77.
The principal has been reduced. The interest is worked on the reduced principal.
4. If the lower-interest card is paid off first, while the interest on the higher-interest card is paid, the tables would look like the following:
Higher-Interest Card:Month 1 2 3 4 5 6 7
Principal 1,311.48 1,311.48 1,297.73 1,028.80 732.71 406.71 47.79
Interest accrued 132.46 132.46 131.07 103.91 74.00 41.08 4.83
Payment 132.46 146.21 400.00 400.00 400.00 400.00 52.62
Ending balance 1,311.48 1,297.73 1,028.80 732.71 406.71 47.79 0
Lower-Interest Card:Month 1 2 3 4 5 6
Principal 475.00 238.34 0 0 0 0
Interest accrued 30.88 15.49 0
Payment 267.54 253.79 0
Ending balance 238.34 0 0 0
5. The savings by paying off the higher-interest card first is $91.86. This is the difference in interest by choosing to pay off the higher-interest card first before the lower-interest card.

What is the equation of this line in slope-intercept form?
A) y=-1/4x-2
B) y=1/4x-2
C) y = 4x-2
D) don't know
Answer:
y = -1/4x - 2
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
To solve for b, use x = 0:
y = m(0) + b
y = b
y = -2, so b = -2
To solve for m, remember that slope is Δy/Δx.
m = Δy/Δx
Given the two points, (0, -2) and (4, -3), we input them to find the slope:
m = [-3 - (-2)]/(4 - 0)
m = -1/4
Therefore, y = -1/4x - 2.

Find the probabilities of getting
O Threes
1 Three
2 Threes
3 Threes
4 Threes
Answer:
If all you care about is whether you roll 2 or not, you get a Binomial distribution with an individual success probability 1/6. The probability of rolling 2 at least two times, is the same as the probability of not rolling 2 at zero or one time.
the answer is, 1 - bin(k=0, n=4, r=1/6) - bin(k=1, n=4, r=1/6). This evaluates to about 13%, just like your result (you just computed all three outcomes satisfying the proposition rather than the two that didn’t).
Step-by-step explanation:
The probabilities of getting :
O Threes is 0.48
1 Three is 0.095
2 Threes is 0.019
3 Threes is 5/1296
4 Threes is 1/1296
What is a binomial distribution ?When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution.The likelihood of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.A popular probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters.It totals the number of trials when each trial has an equal chance of producing a particular result.the total out come = 6* 6* 6* 6 =1296
Find the probabilities of getting
O Threes =(5/6)^4 = 0.48
1 Three = 1/6*(5/6)^3 = 0.095
2 Threes = 1/6* 1/6* 5/6 *5/6 =0.019
3 Threes = 1/6* 1/6* 1/6 *5/6 = 5/1296
4 Threes =(1/6 )^4 =1/1296

is 2.4, 4.5 and 5.2 a right triangle?
Answer:
No
Step-by-step explanation:
Use the pythagorian theorm to find whether it's a right triangle or not.
So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared
5.2 squared= 2.4 squared+ 4m5 squared
27.04= 26.01
It's not equal so the triangle isn't a right triangle.
