A bowl contains 10 blue and 7 red marbles. Four (4) marbles are drawn at random from the
bowl. Calculate the probability of two blue marbles drawn when sampling is done with replacement
Step-by-step explanation:
Answer. The probability of picking a blue marble from the blue urn is 2/6=1/3. The probability of picking a blue marble from the black urn is 11/15. The two events are independent so the probability of a blue marble from each urn is the product of the two separate probabilities=1/3×11/15=11/45.

Answer:
x = 2
Explanation:
[tex]\frac{3x-1}{5} =\frac{x+1}{3}[/tex]
First, make sure they both have common denominators ( 15 )
5 × 3 = 15 and 3 × 5 = 15
Whatever you do to the denominator you have to apply to the numerator. So, multiply the numerator and denominator of the first fraction by 3.
[tex]\frac{3*(3x-1)}{3*5}[/tex] = [tex]\frac{3(3x-1)}{15}[/tex]
Next, multiply the numerator and denominator of the second fraction by 5.
[tex]\frac{5*(x+1)}{5*3}[/tex] = [tex]\frac{5(x+1)}{15}[/tex]
Now we have: [tex]\frac{3(3x-1)}{15} =\frac{5(x+1)}{15}[/tex]
Use distributive property on the numerators of both fractions.
[tex]\frac{9x-3}{15} =\frac{5x+5}{15}[/tex]
Since the denominators are equal we can ignore them for now and find x.
9x - 3 = 5x + 5
We need to move like terms to different sides to isolate x. First, we can subtract 5x from both sides.
9x - 5x - 3 = 5x - 5x +5
4x - 3 = 5
Then, we can add 3 to both sides to cancel out the -3.
4x - 3 + 3 = 5 + 3
4x = 8
Finally, to find x we divide both sides by 4.
4x ÷ 4 = 8 ÷ 4
x = 2

What is the value of x in the solution to this system of equations?
4x+7y=85
x=2y−5
A. x = -9
B. x = 9
C. x = 8
D. x = 3
Answer:
B
Step-by-step explanation:
I used substitution to solve this system. I'll run through all of my steps below:
[tex]4x+7y=85\\x=2y-5[/tex]
I'm going to replace the 'x' values in the first equation with the entire second equation.
[tex]4(2y-5)+7y=85[/tex]
[tex]8y-20+7y=85\\15y-20=85\\15y=105\\y=7[/tex]
Now that we know what y equals, we can go back and solve for x.
[tex]x=2(7)-5\\x=14-5\\x=9[/tex]

can you feel in the blanks
Answer:
First blank would be 25, Second blank would be 75.
Step-by-step explanation:
In order to figure out the blanks, we must figure out the original function first.
How do we do that?
-> we put in the points that we already have- in to equation:
y = ax + b
If we put the 6, 10 in to x, y , we would get :
10 = 6a + b
If we put the 12, 20 in to x, y , we would get :
20 = 12a + b
because these share the "+b" they can be subtracted.
10 = 6a + b
- 20 = 12a + b
--------------------------------------
and this would be :
-10 = -6a, a = 5/3.
we can partly complete the equation.
y = 5/3x + b, and by putting in the numbers, we can figure out that b=0.
The full equation have : y = 5/3x
now, put 15 and 45 in to the x and see what you get!
y=25, 75

PLEASE NEED HELP ASAP IM GIVING ALL MY POINTS THIS SHOULD BE A EASY QUESTION.
Answer:
Function 1 is not a function.The domain and range of the first function respectively are [tex]\text{ \{-3, 0, 1, 5\}}[/tex] and [tex]\text{ \{-4, -2, -1, 1, 3\}}[/tex].Function 2 is a function.The domain and range of the second function respectively are [tex]\text{ \{-2, -1, 0, 1, 2\}}[/tex] and [tex]\text{ \{-7, -2, 1\}}[/tex].Step-by-step explanation:
In math, every function has a domain and a range.
The domain of the function is all of the x-values for which the function is true. These can be found on the x-axis for every position at which the function exists or crosses the x-axis.The range of the function is all of the y-values for which the function is defined. The range can be found in the same manner as the domain - for every y-value at which the function exists, it is apart of the range.Therefore, with this information given to us, we need to also know about coordinate pairs. Coordinate pairs are written in (x, y) form.
Functions are classified in four ways:
One-to-one functions: Functions are considered to be one-to-one functions if there are unique y-values (no y-values are repeated) and there is one x-value for every one y-value.Onto functions: Functions are considered to be onto functions if there are unique x-values. These x-values cannot repeat, but different x-values can be connected to the same y-values.Both one-to-one & onto: Functions are considered both one-to-one and onto when there is exactly one x-value for every one y-value.Neither one-to-one or onto: Functions are considered to be neither an one-to-one function or an onto function when they have two or more of the same y-values assigned to the same x-values. A function cannot exist if y-values are duplicated on a x-value.Finally, the domain and range should be written in ascending order. Therefore, the lowest number should be written first in the domain and the highest number should be written last.
Function 1
We are given the function: [tex]\text{ \{(-3, 3)}, (1, 1), (0, -2), (1, -4), (5, -1) \} }[/tex].
Using the information above, we can pick out our x and y-values from the function.
Values of Domain: -3, 1, 0, 1, 5
Values of Range: 3, 1, -2, -4, -1
Now, we need to arrange these in ascending order.
Domain Rearranged: -3, 0, 1, 1, 5
Range Rearranged: -4, -2, -1, 1, 3
Using these values, we can see what values we have.
For x-values:
x = -3: 1 value
x = 0: 1 value
x = 1: 2 values
x = 5: 1 value
For y-values:
y = -4: 1 value
y = -2: 1 value
y = -1: 1 value
y = 1: 1 value
y = 3: 1 value
Therefore, we can begin classifying this function. Because we have all separate y-values, we have a function. However, we have two of the same x-value, so we have an onto function.
Now, we can create our domain and range in the set. We use the same formatting given for the first function. We list the values in ascending order and list them in brackets to show that they are apart of a set.
The domain values are the x-values, so they are [tex]\text{ \{-3, 0, 1, 5\}}[/tex].
The range values are the y-values, so they are [tex]\text{ \{-4, -2, -1, 1, 3\}}[/tex].
Therefore, the domain and range for function one are defined, but this is not a function. Because the x-values repeat, it cannot be a function.
Function 2
We are given a table of values that needs to be translated into the set notation. This makes it easier to identify the values. We are given x-coordinates in the top row and y-coordinates in the bottom row. And, the table is set up to where the x-value directly above the y-value makes a coordinate pair. Using this, we can create the set function.
The set function is [tex]\text{ \{(-2, -7), (-1, -2), (0, 1), (1, -2), (2, -7)\}}[/tex].
Now, we can use the same method as above to pick out the x and y-values and reorder them to be from least to greatest.
Values of Domain: -2, -1, 0, 1, 2
Values of Range: -7, -2, 1, -2, -7
Now, we rearrange these.
Domain Rearranged: -2, -1, 0, 1, 2
Range Rearranged: -7, -7, -2, -2, 1
Now, we can check how many times the function presents each coordinate.
For x-values:
x = -2: 1 value
x = -1: 1 value
x = 0: 1 value
x = 1: 1 value
x = 2: 1 value
For y-values:
y = -7: 2 values
y = -2: 2 values
y = 1: 1 value
Now, we can classify the function. The x-values are unique, but the y-values are repeated. Therefore, because the x-values are assigned to one y-coordinate and they are unique, this is not an one-to-one function. Additionally, it cannot be an onto function because the y-values are not unique - they are repeated. Therefore, it is neither an one-to-one function or an onto function. If this function were graphed, it would actually reveal a parabola. However, it is still a function.
The domain values are the x-values, so they are [tex]\text{ \{-2, -1, 0, 1, 2\}}[/tex].
The range values are the x-values, so they are [tex]\text{ \{-7, -2, 1\}}[/tex].

Salvatore purchased several magazines for $2 each and books for $3 each. If he spent $160 on a total of 60 books and magazines altogether, what would be the number magazines that Salvatore purchased?
Answer:
the number of magazines purchased is 20
Step-by-step explanation:
As it is mentioned in the question that there is a total of 60 books + magazine altogether
Here we used the following equations
Let us assume the number of magazines be x
ANd, the number of books be y
x + y = 60 .............(1)
2x+ 3y = $160 ..........(2)
Now multiply with 2 in the equation 2
Then it comes
2x + 2y = 120
2x + 3y = 160
Solve these equations
y = 40
Now the x value is
x + 40 = 60
x = 20
Hence, the number of magazines purchased is 20
If 1,200 cm2 of material is available to make a box with a square base and an open top, find the maximum volume of the box in cubic cm. For example, if the answer is 2,000 cm3 write 2000.
Answer:
4000cm³Step-by-step explanation:
Volume of the rectangular box = x²h
Surface area S = x²+4xh
x is the side length of the square base
h is the height
Given
Surface area = 1200cm²
Substitute into the formula S = x²+4xh
1200 = x²+4xh
From V = x²h
h= V/x²
1200 = x² + 4x (V/x² )
1200 = x² + 4V/x
1200x = x³ + 4V
1200x - x³ = 4V
V = 1200x/4- x³/4
V = 300x - x³/4
To maximize the volume, dV/dx = 0
dV/dx = 300 -3x²/4
0 = 300 -3x²/4
0 = 1200 - 3x²
3x² = 1200
x² = 400
x = 20cm
Since 1200 = x²+4xh
1200 = 400+80h
80h = 1200-400
80h = 800
h = 10cm
Find the volume;
Volume = 400 * 10 Volume -= 4000
Hence the maximum volume of the box in cubic cm is 4000 cm³
