Answer:
1/5
Step-by-step explanation:
To find this you would need to multiply the probability of pulling a white marble to the probability of pulling out a green marble.
1)First you would need the probability of pulling out a white marble. There are 10 marbles in total and out of those 2 are white. So the probability of pulling out a white marble would be 2/10. If you simplify that you would get 1/5 for the probability of pulling out a white marble.
2)Next, you would find the probability of pulling out a green marble. Using the same process that we used to find the probability of pulling out a white marble, we would find the answer to be 3/10. All that we did here was green marbles/total marbles. By filling that in we got 3/10 for the probability of pulling out a green marble.
3)Now all that is left is doing probability of pulling a white marble × probability of pulling out a green marble. This would be 1/5 × 3/10. After solving the answer would be 3/15 which we would simplify down to 1/5 as our final answer.

Step-by-step explanation:
Evaluate p/n if n = 2 and p = -8
Answer:
-4
Step-by-step explanation:
-8/2= -4
Answer:
-1/4 or -0.25
Step-by-step explanation:
n=2 and p=-8
substitute p as the numerator and n as the denominator in the fraction
2/-8 simplifies to 1/-4, the sign moves to the front of the fraction because any positive number divided by a negative number will be negative and it is common practice, so the answer is -1/4.
-1/4 is equal to -0.25 in decimal. -0.25 is 1/4 of -1.

64.8=6(m+2.9)
what is m
please help me and explain how did you get your answer
Answer:
= −11.2
Step-by-step explanation:
64.8=6(m+22)
We move all terms to the left:
64.8-(6(m+22))=0
We calculate terms in parentheses: -(6(m+22)), so:
6(m+22)
We multiply parentheses
6m+132
Back to the equation:
-(6m+132)
We get rid of parentheses
-6m-132+64.8=0
We add all the numbers together, and all the variables
-6m-67.2=0
We move all terms containing m to the left, all other terms to the right
-6m=67.2

What is (f+g)(x)?
f(x)=
- 2x2–9x
g(x)=5x
Write your answer as a polynomial or a rational function in simplest form.
Answer:
-2x²-4x or -2x(x+2)
Step-by-step explanation:
(f+g)(x) means we are adding the values of f(x) and g(x):
f(x) = -2x²-9x
g(x) = 5x
(f+g)(x) = -2x²-9x+5x = -2x²-4x = -2x(x+2)

1/9 of the shirts sold at Peter’s shop are striped. 5/8 of the remainder are printed. The rest of the shirt are plain colored shirts. If Peter’s shop has 81 plain colored shirts, how many more printed shirts than plain colored shirts does the shop have?\
Thanks
Spectrier
Answer:
54 more printed than plain shirts.
Step-by-step explanation:
Alright, so... if 1/9 of the shirts are striped and 5/8 of the remaining shirts are printed then 3/8 of the remaining shirts are plain. if 81=3/8 of the remaining shirts then 1/8 of the remaining shirts is 27 shirts. 27x5=135 meaning 135 of the remaning shirts are printed. If 1/8 of the remaining shirts is 27, there are 216 total remaining shirts. This also means that 216 is 8/9 of all of the shirts. Since 27 is 1/8 of the remaining shirts, 216+27=the total amount of shirts. 216+27=243. 243/9=27 meaning that 1/9 of the shirts is 27 (which also means I did that math for no reason, it's 2:00 am, my brain can't funtion rn XD). 135 printed shirts-81 plain shirts=54. There are 54 more printed shirts than plain shirts. Sorry if I am wrong, hope it helps. Have a wonderful day!

Answer:
1: 7.5 2: 25 3: 14.2
Step-by-step explanation:
For all of these, you want to use the Pythagorean Theorem, which is a^2+b^2=c^2
1. you would have to plug in 13 for b, and 15 for c, because 15 is the hypotenuse
a^2+13^2=15^2
now, solve for a
a^2+169=225
225-169=56
a^2=56
to undo a squared, you have to take the square root of both sides
sqrt(56) is about 7.5
to check, you would have to plug in 7.5 for a
2. you would start off the same way, but this time we are solving for c
15^2+20^2=c^2
225+400=c^2
625=c^2
take the square root of 625
25 is your answer
if you want to check, plug in 25 for c
3. we are trying to find the hypotenuse again, so we are solving for c
5.1^2+13.2^2=c^2
26.01+174.24=200.25
200.25=c^2
take the square root once again
it is approximately 14.2
if you want to check, plug in 14.2 for c

Out of 20 cookies, 3/4 are chocolate chip. How many cookies are chocolate chip?
Please I need help! ASAP!
Answer:
15 cookies are chocolate
Step-by-step explanation:
Well it's actually quite easy, just think about it this way. 20/4=5 since there's a 4 as the denominator in the fraction. Or there's many other ways to find the answer. At the end of the day, you'll get the same answer just some ways are harder especially compared to the one I did.
Since we divided 4 into 20, we know the answer to that is 5.
3/4=15 if you think about it in a certain way.
Therefore the answer is 15 since 3x5= 3/4 and both of those equal 15
Hope this helps
Answer: 15
Step-by-step explanation:
So 4/4 = 20 cookies so then 3/4 is 15 cookies. All your doing is counting by 5’s.
For example, 5, 10, 15, 20
1/4 2/4 3/4 4/4
So your looking for 3/4 which is 15
Answer: 15 chocolate chip cookies

Suppose that there are 20 numbers in a data set and that they are all different. How many of the values in this data set are between the first quartile and the median?
Answer:
4
Step-by-step explanation:
Since the first quartile is at 25%, 25% of 20 is 5. The median is the 50% mark of the set, and 50% of 20 is 10. So, there are 4 numbers between the 5th data point and the 10th, which are the 6th,7th,8th, and 9th data points.
