Answer: To find the mean of a data set, add all the numbers together, then divide the answer by how many numbers there were
Step-by-step explanation:
Example: 1,5,2,6,9,4
First add them all so 1 + 5 + 2 + 6 + 9 + 4 = 27
Then divide by how many numbers there were so 27/6=4.5
4.5 is the mean of the data set

Solve the system of linear equations below. 2x + 3y = 2 x + 6y = 4 A. x = 0, y = B. x = 2, y = - C. x = , y = D. x = 4, y = -2
Answers
Step-by-step explanation:
2x + 3y = 2
x + 6y = 4
2(4-6y) + 3y = 2
x= 4- 6y
8-12y + 3y = 2
x= 4- 6y
-9y =-6 =) y = 2/3
x= 4- 6*2/3 = 0
A. x = 0, y = 2/3

A bag has 8 red marbles, 4 green marbles, and 2 yellow marbles. Bill draws a red marble from the bag and does not replace it. What is the probability of Bill drawing a yellow marble next? A. 1/7 B. 1/13 C. 2/13 D. 1/14
Answers
Answer:
c. 2/13
Step-by-step explanation:
The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.
So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.
7+4+2 = 13
2/13
So the probability of Bill drawing a yellow marble would be 2/13.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
Each week, Robbie earns $x mowing lawns and receives $15 as his allowance.

What are some other ways Robbie can write the above expression? Check all that apply.
A. 3x + 45
B. x + 15
C. 3x + 15
D. 3(x + 15)
Answers
Answer:
A. 3x + 45
D. 3(x + 15)
Step-by-step explanation:
x + 15 + x + 15 + x + 15 = (x + 15) + (x + 15) + x + 15) = 3(x + 15) = 3x + 45
Answer:
A. 3x + 45
D. 3(x + 15)
A works because he gets payed “x” 3 times, making 3x. He gets payed $15 3 times so that makes $45.
D works because when you use the distributive property to solve you get 3x+45

9m - 8
Step-by-step explanation:
We know that,
( - ) × ( - ) = ( + )
( + ) × ( + ) = ( + )
( - ) × ( + ) = ( - )
Accordingly, let us solve it now.
10m + ( – 8 ) + 9m + ( – 10m )
Solve the brackets.
10m - 8 + 9m - 10m
Combine like terms.

Answer:
The answer to your question is:
No solutions: 7−5+3x−1= 3x + 7
One solution: 7−5+3x−1= 2x + 4
Infinitely Many Solutions 7−5+3x−1= 3x + 1
Step-by-step explanation:
No solutions means it results in no x AND a false statement like 3 = 0.
One solution means it results in x = a number.
Infinite solutions means its results in no x and in a true statement like 3=3.
So to get no solutions: 7−5+3x−1= 3x + 7
This will eliminate the x and result in 1 = 7 which is false.
One solution: 7−5+3x−1= 2x + 4
Which will result in x= 3
Infinitely Many Solutions 7−5+3x−1= 3x + 1
This will eliminate the x and result in 1 = 1 which is true.
Thus the answer to your problem is:
No solutions: 7−5+3x−1= 3x + 7
One solution: 7−5+3x−1= 2x + 4
Infinitely Many Solutions 7−5+3x−1= 3x + 1
