Answer:

Step-by-step explanation:

The ratio everything is 1:2. DE joins two midpoints. There are many properties involved in saying that. The most important for this question is that DE = 1/2 BC

That means that the sides in the small upper triangle (ADE) are 1/2 the size of the sides in the larger triangle.

So if DE = 8 then BC must be twice as big or BC = 16

The median and mean<br> PLZ HELP

joja [24]

Step-by-step explanation:

Data Set A: 14, 21, 24, 28, 28, 35

Data Set B: 18, 19, 21, 25, 29,32

Median:

Data Set A = 26

24 + 28 = 52

52/2 = 26

Data Set B = 23

21 + 25 = 46

46/2 = 23

Mean:

Data Set A = 25

14 + 21 + 24 + 28 + 28 + 35 = 150

150/6 = 25

Data Set B = 24

18 + 19 + 21 + 25 + 29 + 32 = 144

144/6 = 24

Using the quadratic formula to solve 11x^2-4x=1, what are the values of X?

Rashid [163]

The correct answers for x would be $\frac{2 +/- \sqrt{15} }{11}$ .

In order to find this, we must first get the equation to equal 0. In order to do that, subtract 1 from each side to get the following.

11 $x^{2}$ - 4x - 1 = 0

Knowing this we can now use the quadratic equation using a = 11, b = -4 and c = -1. The quadratic equation is below.

$\frac{-b +/- \sqrt{ b^{2} - 4ac} }{2a}$

Now we can plug the values into the equation to solve.

$\frac{4 +/- \sqrt{ -4^{2} - 4(11)(-1)} }{2(11)}$

Then simplify using the order of operations.

$\frac{2 +/- \sqrt{15} }{11}$ .
