Answer:
A and C is true statements
Median of 10, 55, 34, 21
First we arrange number in ascending or descending
10, 21, 34, 55 in ascending.
Median is the middle number and this is between 21 and 34.
We find the average:
(21 + 34) /2 = 55/2 = 27.5
Median is 27.5.
Answer:
Option D is correct.
x y
0 5
1 10
2 20
Step-by-step explanation:
Given the equation:
.....[1]
Here, x is the input variable and y is the output variable.
For x =0
Substitute in equation [1]; we have;
For x = 1
Substitute in equation [1]; we have;
For x =2
Substitute in equation [1]; we have;
Therefore, the table values which is correct for the equation
is;
x y
0 5
1 10
2 20
Answer:
x=12
Step-by-step explanation:
Midpoint B of segment AC creates both equal segments AB and BC. The midpoint halves out AC therefore AB=BC
The equation would look like 2x-5=x+7 where you want to isolate x fully. First you want to add 5 on both sides of the equation so that you get 2x=x+12. Next subtract x from both sides of the equation to then get x=12.
