A bag of marbles contains 6 blue marbles and 1 green marble. Mary and Frank will draw a blue marble followed by a green marble, without replacing the first marble. Mary says the probability will be 6/49, and Frank says that the probability will be 1/7. Who is correct? Explain and justify your answer by showing work.
---------------Is correct because___
Answer:
Frank is correct
Step-by-step explanation:
Because if the denominator was 49 then the numerator would be 7
1/7=1/7
1/7=7/49
7*7=49
7*1=7
7/49=1/7

Answer:
[tex](0,-3)[/tex]
[tex](5,0)[/tex]
[tex](10,3)[/tex]
[tex](20,9)[/tex]
Step-by-step explanation:
Given
[tex]3x - 5y = 15[/tex]
Required
Form 4 pairs of (x,y) values
This question will be answered based on assumptions of x and y values;
Haven said that:
For point 1
Take x = 0
Substitute 0 for x in [tex]3x - 5y = 15[/tex]
[tex]3(0) -5y = 15[/tex]
[tex]-5y = 15[/tex]
Solve for y
[tex]y = 15/-5[/tex]
[tex]y = -3[/tex]
So; the first pair is:
[tex](0,-3)[/tex]
For point 2:
Take y = 0
Substitute 0 for y in [tex]3x - 5y = 15[/tex]
[tex]3x - 5(0) = 15[/tex]
[tex]3x = 15[/tex]
Solve for x
[tex]x = 15/3[/tex]
[tex]x = 5[/tex]
So, the pair is
[tex](5,0)[/tex]
For point 3:
Take x = 10
Substitute 10 for x in [tex]3x - 5y = 15[/tex]
[tex]3(10) - 5y = 15[/tex]
[tex]30 - 5y = 15[/tex]
Collect Like Terms
[tex]-5y = 15 - 30[/tex]
[tex]-5y = -15[/tex]
Solve for y
[tex]y = -15/-5[/tex]
[tex]y = 3[/tex]
So, the pair is:
[tex](10,3)[/tex]
For point 4:
Take y = 9
Substitute 9 for y in [tex]3x - 5y = 15[/tex]
[tex]3x - 5(9) = 15[/tex]
[tex]3x - 45 = 15[/tex]
Collect Like Terms
[tex]3x = 45 + 15[/tex]
[tex]3x = 60[/tex]
Solve for x
[tex]x = 60/3[/tex]
[tex]x = 20[/tex]
So, the pair is:
[tex](20,9)[/tex]

800x40 explanation pls
Answer:
800x40=32000
Step-by-step explanation:
Basically its 800 40 times.
Answer:
32,000
Step-by-step explanation:
First put 800 over 40
Second, multiply the 3rd zero by the first zero of 40
Multiply the 2nd zero by the same zero of 40
Multiply 8 by 4 and the result should be 800
Then you multiply 800 by 4.
0 x 4 is 0
0 x 4 is 0
8 x 4 is 32
(Make sure you add the zero from 40)
Put it together and you get 32,000
Jillian was asked to translate the expression 9 n into words. She wrote "a number increased by nine. " Which best describes the accuracy of Jillian’s answer? It is incorrect. The variable would come first in the expression "a number" (n) "increased by" ( ) "nine" (9). It is incorrect. The phrase "increased by" refers to the inequality symbol "greater than" (>), not addition. It is correct. A number increased by nine (n 9) is the same as nine increased by a number (9 n). It is incorrect. A number increased by nine refers to a multiplication expression (n times 9).
A number increased by nine (n + 9) is the same as nine increased by a number (9 + n), the correct option is C.
What is the pharse in mathematics?
A mathematical phrase is a set of words or a combination of words and numbers that can be written as a mathematical expression.

Please help me solve this I need some help
Answer:
f = 8
Step-by-step explanation:
Apply the distributed property, so it now looks like this: 2f - 10 = 6Add 10 to each side, so it now looks like this: 2f = 16Divide each side by 2 to cancel out the 2 next to f. It should now look like this: f = 8I hope this helps!
Answer:
f=8
Step-by-step explanation:
Step 1: Distribute
2(f) + 2(-5) = 6
2f - 10 = 6
Step 2: Add 10 to both sides to get 2f alone
2f = 16
Step 3: Divide both sides by 2 to get f alone
f = 8
What is the approximate value of q in the equation below? q log subscript 2 baseline 6 = 2 q 2 –1.613 –1.522 0.585 3.079
The approximate value of q in the logarithmic equation is 0.585.
The given logarithmic equation is [tex]\rm q+log_2(6)=2q+2[/tex]
It is required to find the value of 'q'.
What is Logarithm?
It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b=c\\\rm log_ac=b[/tex]
We have a logarithmic equation:
[tex]\rm q+log_2(6)=2q+2[/tex]
After simplification the above equation we get;
[tex]\rm q+log_2(6)=2q+2\\\rm q-2q=-log_2(6)+2\\\rm -q=-log_2(6)+2\\[/tex].....(1)
From the logarithmic table, we get the value of [tex]\rm log_2(6)[/tex]
[tex]\rm log_2(6)=2.5849[/tex]
Putting this value in equation (1), we get:
[tex]\rm -q=-log_2(6)+2\\\rm -q=-2.5849+2\\\rm -q=-0.5849\\\rm q=0.5849 \approx 0.585\\[/tex]
Thus, the approximate value of q in the logarithmic equation is 0.585.

Answer:
[tex]\mathsf{y=-\dfrac13x+5}[/tex]
Step-by-step explanation:
Slope-intercept form of a linear equation: [tex]\mathsf{y=mx+b}[/tex]
(where m is the slope and b is the y-intercept)
From inspection of the graph, the y-intercept is at (0, 5)
Therefore, b = 5
Choose another point on the line, e.g. (3, 4)
Now use the slope formula to find the slope:
[tex]\mathsf{slope=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
where:
[tex]\mathsf{(x_1,y_1)=(0,5)}[/tex][tex]\mathsf{(x_2,y_2)=(3,4)}[/tex][tex]\implies \mathsf{slope=\dfrac{5-4}{0-3}=-\dfrac13}[/tex]
Therefore, the equation of the line is:

16. Given that I lm, find the value of 'X'.
4x + 10
m
8x – 25
Answer:
x = 8.75
Step-by-step explanation:
The given angles are corresponding and congruent, thus
8x - 25 = 4x + 10 ( subtract 4x from both sides )
4x - 25 = 10 ( add 25 to both sides )
4x = 35 ( divide both sides by 4 )
x = 8.75

if a meter has 100 centimeters what is the ratio of 15 cm to 2 m
?
the answer is 15cm (pls mark brainlest)
Answer:
3:40
Step-by-step explanation:
We need both measurements in the same units.
1 m = 100 cm
2 m = 2 × 1 m = 2 × 100 cm = 200 cm
15 cm to 2 m = 15 cm to 200 m
Divide both numbers in the ratio by 5 cm.
15 cm to 200 cm = 3:40

Please help,I'm confused as to how to find the area with the shapes connected,thankyou.
Answer: 104 ft²
Step-by-step explanation:
To find the area of the figure, we can find the area of the rectangle and the triangle. After that, we add the two areas together.
Rectangle
A=bh
A=10×8 [multiply]
A=80
----------------------------------------------------------------------------------------------------------------
Triangle
A=bh/2
A=6×8/2 [multiply]
A=48/2 [divide]
A=24
Now that we have the areas, we can add them together.
A=80+24 [add]
A=104 ft²
Now, we know that the area is 104 ft².
