Find the mean. There will be 6 numbers, so divide by 6

14 = (9 + 12 + 17 + 15 + 13 + x)/6

Simplify

14 = (x + 66)/6

Multiply 6 to both sides

14(6) = (x + 66)/6(6)

84 = x + 66

Subtract 66 from both sides

84 (-66) = x + 66 (-66)

x = 84 - 66

x = 18

18 is your answer for x

hope this helps

The answer to your question would be 15

You find out what the median is (13) and then you look for the bigger number than what your looking for (15)  add it to the list then find the median with the set of numbers and 15 then you got your answer

Fid the value of the expression
Paha777 [63]

Answer:

2

Step-by-step explanation:

The question askes what is k divided by m (k/m) when k is equal to 8 and m is equal to 4. So, plug the values into the original questions 8÷4.  This means that the number 8 is being split into 4 groups. When 8 is divided into 4 groups each group is left with 2. Therefore, the answer is 2.

Another way to solve this is to make a fraction. 8÷4 is the same as 8/4. If you simplify that fraction you also get 2.

If angle YWZ = 17, what is angle WXY?
marusya05 [52]
We know that

step 1
if ∡YWZ=17°
then
∡XWZ=17°*2-----> 34°----> because triangle XWY and triangle YWZ are congruents

step 2
∡WXY=∡WZY-------> because triangle XWY and triangle YWZ are congruents
we know that 
<span>the sum of the internal angles of a triangle is 180 degrees
</span>so
180°=∡XWZ+2*∡WXY---------> ∡WXY=[180-∡XWZ]/2
∡WXY=[180-34°]/2-------> ∡WXY=73°

the answer is
∡WXY=73°
