What is the median of 12,8,5,6,1,10,13,11

neonofarm [45]

The median is the middle value, so put them all in numerical order, (1,2,4,6,7, ect.), and find the middle. If there is two numbers in the middle find the number exactly between them.
Hope this helps!

Answer:

Option B: 3x + 3y - 3

Step-by-step explanation:

In an isosceles triangle, the two congruent sides are equal.

We are told the base is; x - y - 2 units

Now let each of the congruent sides be represented as A.

Thus the perimeter equation will be;

P = 2A + x - y - 2

Now, we are told that the perimeter is; 7x + 5y - 8 units

Thus;

7x + 5y - 8 = 2A + x - y - 2

Rearranging gives;

7x - x + 5y + y - 8 + 2 = 2A

2A = 6x + 6y - 6

Divide through by 2 to give;

A = 3x + 3y - 3 units

4. (10 points) From the given triangle:

katrin2010 [14]

Answer:

sinθ = y/r sinθ = $\frac{-6}{10} = \frac{-3}{5}$

cosθ = x/r cosθ = $\frac{8}{10} = \frac{4}{5}$

tanθ = y/x tanθ = $\frac{-6}{8} =\frac{-3}{4}$

cscθ = r/y cscθ = $\frac{-5}{3}$

secθ = r/x secθ = $\frac{5}{4}$

cotθ = x/y cotθ = $\frac{4}{3}$

explanation:

r = $\sqrt{(8)^{2}+(-6)^{2} }$

r = 10

x = 8

y = -6

r = $\sqrt{(4)^{2}+(3)^{2} }$

r = 5

x = 4

y = 3
