Answer:
<h2>
12</h2>
Solution,
Summation FX= 5+10+6+12+X
=33+x
N(total no.of items)=5
Now,
Mean= summation FX/N
or 9=33+X/5
or 9*5=33+X ( cross multiplication)
or 45=33+X
or -x=33-45
or -x=-12
X=12
Hope this helps...
Good luck on your assignment..

- First subtract 116-72
-then divide that answer by nine
-round
Answer:
The first thing you need to do is, have a square whose area is 11² = 121 square inches. Then we are going to multiply the radius by π which is 3.14 the area of the circle with the radius 4 is equal to 3.14 × 4² = 3.14 × 16 = 50.24, you need to divide the calculated radius times π (3.14) you can get the answer and you need to round your answer to the nearest hundredth probability that the dart will hit within the circle is equal to 50.24 ÷ 121 = 0.4152066116 which is rounded to 0.04152 or 41.52% this assumes the dart will always hit the square at least.
Answer:
x = 34
Step-by-step explanation:
x/3 - 7/3 = 9
Combine like terms
(x-7)/3 = 9
Multiply each side by 3
(x-7)/3 * 3 = 9*3
x-7 = 27
Add 7 to each side
x-7+7 = 27+7
x = 34
