Answer:
c. the sample portion is unbaised
Step-by-step explanation:
plato
I would subtract the 2nd from the first one
so -4x - -2x = -2x
4y - 4y = 0
-20 - -2 = -18
-2x = -18
now I would divide that by -2 to get the value for x
so no we have x = 9
now you just have to substitute that into one of the equations and simplify to get y
-2 X 9 + 4y = -2
-18 + 4y = -2
4y =16
y = 4
Answer:

Step-by-step explanation:
Notice that we can get from the x-coordinate of A, 1, to the x-coordinte of A', -2, by subtracting 3 from the x-coordinate of A. More formaly:



Similarly, we can get from the y-coordinate of A, 5, to the y-coordinate of A', 3, by subtracting 2 from the y-coordinte of A. More formaly:



Now we now that to get to A' from A, we need to subtract 3 to the x-coordinate of A and subtract 2 to the y-coordinate. Knowing this, we can create the expression to translate any point of the polygon ABCD to create the polygon A'B'C'D':

Answer:
<u>585/4</u> or <u>146.25</u>
Step-by-step explanation:
10 x 6 1/2 x 2 1/4
10 x 13/2 x 9/4
5 x 13 x 9/4
65 x 9/4
<u>585/4 = 146.25</u>
Value of x is 2.
Step-by-step explanation:
- Step 1: Given that x+1/3 = x/2
Cross-multiply to find the value of x.
⇒ 2(x + 1) = 3x
⇒ 2x + 2 = 3x
⇒ x = 2
