Answer:
The given system of equations has infinitely many solutions.
Step-by-step explanation:
Given equations are:
4x-2y = 28
2x-y = 14
From equation 2:
[tex]2x-14 = y[/tex]
Putting in equation 1:
[tex]4x-2(2x-14) = 28\\4x-4x+28 = 28\\28 = 28[/tex]
When this happens in the solution of a system i.e. same constant on both sides of equation, the system of equations has infinitely many solutions.
Hence,
The given system of equations has infinitely many solutions.

5. Leyla will roll a number cube 1-4 and flip a coin. The coin can land on heads or tails. If Leyla rolls the number cube once and flips the coin once, which list contains only the outcomes in which the number cube land on a number greater than 3?
Answers
Answer:
{4H, 4T}
Step-by-step explanation:
The list that contains only the outcomes where the number cube is more than 3 is given below:
Sample space is
= {1,2,3,4}
The results more than 3 is
S = {3}
After this, the sample space i.e. C when the coin is fippled is
C = {H, T}
Here H denotes the Head
T denotes Tail
So, the outcomes would be
= {4} + {H,T}
= {4H, 4T}
How many tiles each 30cm by 30cm will be needed for floor
Answers
not possible .. what are the dimensions
Answer:
Yes not possible but with dimensions
Hers an example
Step-by-step explanation:
Since the tiles are in cm
2
, we have to convert the dimensions of the hall to cm first. It will be 1500 cm by 1200 cm. Hence the area of the floor is
1500×1200=1800000cm
2
.
Area of each tile is 30×20=600cm
2
. Hence the number of tiles required to cover the floor is:
600
1800000
=3000.

find the slope of the line through each pair of points (12, -18) & (-15, -18)
Answers
Answer:
0
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-18 + 18) / (-15 - 12)
0 / -27
= 0
So, the slope is 0.

Round your answer to the nearest whole number.
Answers
distance formula:
d = √[( x₂ - x₁ )² + ( y₂ - y₁ )²]
Given:
x₂ = 12
x₁ = 5
y₂ = 3
y₁ = 7
Solve:
d = √[( 12 - 5 )² + ( 3 - 7 )²]
d = √[( 7 )² + ( -4 )²]
d = √[ 49 + 16 ]
d = √[ 65 ]

Equation #1: 3x + 11 = 11
Equation #2: 3(x - 3) = 45
Answers
Step-by-step explanation:
Given that,
Two equations,
3x + 11 = 11 .....(1)
And
3(x - 3) = 45
or
3x-9=45 ....(2)
Subtract 11 on both sides of equation (1).
3x + 11-11 = 11-11
3x=0
x = 0
Add 9 to both sides of equation (2)
3x-9+9=45+9
3x = 54
x = 18
Hence, the solution of equation (1) is x=0 and form equation (2) x = 18.

Answers
Answer:
The data is skewed left with an outlier.
Explanation:
Skewness occurs when the entries of the data set are either distributed more to the left or more to the right on the number line. In this case, most of the entries lie to the right, so the data set is skewed left.
