It would be 12 because if there are 3 slices divided into 4 it would be 12 small slices
Answer:
11.2467
Step-by-step explanation:
First we need to find the mean
Add up all the data and divide by number of points)
(6+7+8+10+12+13+14+17+17+17+18+19+21+23+24+24+25+27+31+31+32+36+36+39+41+45+45+46+49+50)/30
261/10
26.1
Then to find the mean absolute deviation take each value and find the absolute value from the mean and sum it and then divide by the number of points
((26.1 -6)+(26.1-7)+(26.1-8)+(26.1-10)+(26.1-12)+(26.1-13)+(26.1-14)+(26.1-17)+(26.1-17)+(26.1-17)+(26.1-18)+(26.1-19)+(26.1-21)+(26.1-23)+(26.1-24)+(26.1-24)+(26.1-25)+(27-26.1)+(31-26.1)+(31-26.1)+(32-26.1)+(36-26.1)+(36-26.1)+(39-26.1)+(41-26.1)+(45-26.1)+(45-26.1)+(46-26.1)+(49-26.1)+(50-26.1))/30

Answer:
Area of sector = 21.75 units.
Step-by-step explanation:
Given, BAC is a sector of radius 8.
⇒ AB = 8; AC = 8.
Now, let a line from A passing through O meets the curve BC at P.
⇒AP = 8. (radius of sector).
Given, radius of inscribed circle is 2.
⇒AO = AP- OP = 8-2 = 6.
let the inscribed circle meets AB at Q. so, triangle AQO forms right angle triangle(since, AB is a tangent).
⇒ cos(∠AOQ) = 2/6 (adjacent / hypotenuse)
⇒ ∠AOQ = 70.53° ⇒ ∠OAQ = 180 - 90- 70.53 = 19.47°
⇒ total ∠A = 2× 19.47° = 38.94°.
⇒ area of sector = π×r²×
, where r = 8
⇒ area of sector = 21.75 units.
Answer:A function is a special type of relation where every input has a unique output. Definition: A function is a correspondence between two sets (called the domain and the range) such that to each element of the domain, there is assigned exactly one element of the range.
