Answer:
The chance of picking a yellow marble twice in a row without replacement is 0.22
Step-by-step explanation:
The given number of marbles in the bag = 25 marbles
The number of red marbles in the bag = 5 red marbles
The number of blue marbles in the bag = 8 blue marbles
The number of yellow marbles in the bag = 12 yellow marbles
The chance of picking a yellow marble = 12/25
The chance of picking another yellow when the first one is not replaced = 11/24
Therefore, the chance of picking a yellow marble twice in a row = 12/25 × 11/24 = 1/25 × 11/2 = 11/50
Therefore;
The chance of picking a yellow marble twice in a row without replacement = 11/50 = 0.22

Grade 10 math help please. Please show work
Answer:
43.94?
Step-by-step explanation:
I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.
cos(∅) = [tex]\frac{18}{25}[/tex]
cos(∅) = 0.72
cos⁻¹(0.72) = 43.94

Can you solve this quadratic by taking the square root?: x^2-6x=-8
Answer:
Step-by-step explanation:
To solve this you could complete the square, use the quadratic formula, or factor it. This equation is easily factorable.
x^2-6x+8=0
(x-2)(x-4)=0
So x=(2,4)

simplify as far as possible:3x+4y+7y
Answer:
3x+4y+7y = 3x + 11 y
Step-by-step explanation:
We need to simplify the given expression i.e.
3x+4y+7y
We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y
So,
3x+4y+7y = 3x + 11 y
Hence, the final simplification should be 3x + 11 y.
Solve the system:
x+4y=1
3x+5y=10

P < 4.75 represents the prices p in dollars that Paige is willing to pay for popcorn. The inequality p < 8.00 represents the prices p in dollars that Paige is willing to pay for a movie ticket. At how many theaters would Paige be willing to buy a ticket and popcorn?
Answer:
1 theater
Step-by-step explanation:
Given
[tex]P<4.75[/tex] --- Popcorn
[tex]P < 8.00[/tex] --- Movie
See attachment for the table that shows ticket and popcorn prices at five movie theater chains
Required
The number of theaters that supports the given inequality
The given inequality can be combined to give:
[tex]P < 4.75\ and\ P<8.00[/tex]
From the table entries, only one theater supports this inequality.
Where
[tex]P = 4.25[/tex] --- Movie
[tex]P = 7.25[/tex] --- Popcorn
Which gives:

What is the resulting equation when the expression for y in the second equation is substituted into the first equation-3x+2y=-3
Y=4x+1
Answer:
x=-5/11, y=-9/11. (-5/11, -9/11).
Step-by-step explanation:
3x+2y=-3
y=4x+1
---------------
3x+2(4x+1)=-3
3x+8x+2=-3
11x=-3-2
11x=-5
x=-5/11
y=4(-5/11)+1
y=-20/11+11/11
y=-9/11
4. Which expression is equivalent to - (6x + 9) - (x - 2)?
A. 5x - 3
B. - 2x + 7.5

What is the nth term rule of the linear sequence below?
5,8,11,14,17
(btw it says the nth term not the 9th.)
9514 1404 393
Answer:
an = 5 +3(n -1)
Step-by-step explanation:
The n-th term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, you have first term a1=5 and common difference d=8-5=3, so the n-th term is ...
an = 5 +3(n -1)
_____
If you like, you can simplify this to ...
an = 5 +3n -3
an = 3n +2
Answer:
it's 3n-3

Jim ate 50 cookies yesterday. He ate 3 boxes of cookies and 8 cookies. How many cookies were in each box?
Answer:
Step-by-step explanation:
3b+8c=50c
3b=50c-8c
3b=42c
b=14c
So there are 14 cookies in each box.
Answer:
14
Step-by-step explanation:
First, take away the 8 cookies that were not part of the 3 boxes.
(50 - 8 = 42)
Now we know that 3 boxes of cookies can hold 42 total cookies. However, we need to know how much cookies 1 box can hold. If the 42 cookies are divided evenly between the 3 boxes, our equation would look like this:
42/3 = 14
Therefore, the answer is 14 cookies in each box.

Given that R=7x+5Y find Y when X=9 and R=35 give your answer as an improper fraction in its simplest form
Please help
Answer:
y = -28/5
Step-by-step explanation:
R = 7x +5y
35 = 7(9) + 5y
35 = 63 +5y
-5y= 63- 35
-5y/-5 = 28/-5
Y = -28/5
Answer:
Y = - [tex]\frac{28}{5}[/tex]
Step-by-step explanation:
Given
R = 7X + 5Y ← substitute X = 9, R = 35
35 = 7(9) + 5Y
35 = 63 + 5Y ( subtract 63 from both sides )
- 28 = 5Y ( divide both sides by 5 )
- [tex]\frac{28}{5}[/tex] = Y
