i believe the answer is 9
Step-by-step explanation:
If the area of the sector of the circle is 104/9 square inches. Then the radius of the sector of the circle is 4.51 inches.
<h3>What is a circle?</h3>
It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
The sector of a circle has an area of 104 over 9 square inches and a central angle of 65 degrees.
Then the radius of the sector of the circle will be
Area = (x/360) πr²
Then we have
104/9 = (65/360) πr²
r² = 20.37
r = 4.51 inches
If the area of the sector of the circle is 104/9 square inches. Then the radius of the sector of the circle is 4.51 inches.

Answer:
Mean absolute deviation = 1.6.
Step-by-step explanation:
The mean = (4+4+ 6+ 6+ 7+ 8+ 8 + 8 +9+ 10) / 10
= 7.
List the differences from the mean:
4 - 7 = -3
-3
-1
-1
0
1
1
1
2
3
Sum of the absolute value of the difference
= 3 + 3 + 1 + 1 + 0 + 1 + 1 + 1 + 2 + 3
= 16.
So the Mean Absolute deviation = 16 / 10 = 1.6.
