Best ResponseYou've already chosen the best response.3Can you find area of semicircle?

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3Semicircle is just half the circle. So it's like finding area of circle, but THEN you divide it by 2.

Best ResponseYou've already chosen the best response.0was that right @geerky42 ?

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3Area of circle is \(A = \pi r^2\) So to find area of semicircle, you just use this formula then divide by 2.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0but you said semi circle so wouldn't it be A=1/2pi r

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3My point is, to find semicircle, you just find area of circle, then divide by 2. Get it? Also it's \(\pi r^2\), not just \(\pi r\).

geerky42

Best ResponseYou've already chosen the best response.3So area of semicircle is \(\dfrac{\pi r^2}{2}\)

Best ResponseYou've already chosen the best response.0@geerky42 so 9.42cm2/2=4.71cm2

geerky42

Best ResponseYou've already chosen the best response.3Radius is 3, so you have \(\dfrac{\pi(3)^2}{2} = \dfrac{9\pi}{2}\approx 14.137\)

geerky42

Best ResponseYou've already chosen the best response.3Just remember that \(\pi\approx3.14\)

anonymous

Best ResponseYou've already chosen the best response.0yes you told me that, thats how remember what pi is but how did you get the 9pi over 2

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3you divide 2 because semicircle

Best ResponseYou've already chosen the best response.0thank you though @geerky42

Best ResponseYou've already chosen the best response.3Well, we are not done

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3we got area of semicircle. Now we need to subtract that by area of triangle

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3(Area of semicircle)  (Area of triangle) Right?

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3Ok. Area of triangle is \(\dfrac{1}{2}bh\) Do you know base and height here?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0but we don't have the area of the triangle so we need to solve for the triangle

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so 3 would be our height

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so how would you find the base given only the height

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3We don't really have to use height to find base. Triangle and semicircle share same base, right?

Best ResponseYou've already chosen the best response.0do the MAGIC! drawing thing geerky

geerky42

Best ResponseYou've already chosen the best response.3We know that radius of semicircle is 3, so what is diameter?

anonymous

Best ResponseYou've already chosen the best response.0hahaaaa @camacho01erick that was the best response

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3lol. though I don't see the need to drawing something here lol.

geerky42

Best ResponseYou've already chosen the best response.3maybe I will do magic thing once asker solve something like gif of victory lol.

Best ResponseYou've already chosen the best response.3@Mromanos96 No \(d = 2r\), right?

Best ResponseYou've already chosen the best response.3dw:1433962650107:dw

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3Yeah so diameter is 6. Therefore base of triangle is 6. MAke sense so far?

anonymous

Best ResponseYou've already chosen the best response.0yes so next we have 1/2 6*3

geerky42

Best ResponseYou've already chosen the best response.3\(\dfrac{1}{2}*3*6 = 3*3 = 9\)

Best ResponseYou've already chosen the best response.0how didi you do the gif @geerky42

anonymous

Best ResponseYou've already chosen the best response.0ah how did you get that the only other one i got is a decimal

geerky42

Best ResponseYou've already chosen the best response.3I guess I need to make tutorial @camacho01erick in LaTeX section. I will tag you someday, I promise.

anonymous

Best ResponseYou've already chosen the best response.0good thing i fanned you @geerky42

geerky42

Best ResponseYou've already chosen the best response.3Well, put that in calculator 1/2 * 3 * 6

geerky42

Best ResponseYou've already chosen the best response.3You should get 9, right?

Best ResponseYou've already chosen the best response.3OK. Now do final thing; (Area of semicircle)  (Area of triangle)

geerky42

Best ResponseYou've already chosen the best response.3We have \(14.137  9\)

anonymous

Best ResponseYou've already chosen the best response.0we are /\tlas we will follow and we will not forget and will not forgive

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3Yep. Sorry first area should be \(14.13\) since we have to use \(3.14\) for pi. But anyways your final answer is \(\boxed{5.13~\text{cm}^2}\)

geerky42

Best ResponseYou've already chosen the best response.3Is that clear so far?

Best ResponseYou've already chosen the best response.3So we just need to find how many adult prefer newspapers Then divide it by 252 (total)

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3OK. how nay adults prefer newspaper?

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3Correct. So relative frequency is \(\dfrac{70}{252}=?\)

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3yeah but close. question said at least two decimal places.

geerky42
 one year ago
Best ResponseYou've already chosen the best response.3So we have 70/252 = 2.777777777... So round that to .28

geerky42

Best ResponseYou've already chosen the best response.3Well it is closer to .28 than .27

geerky42
 one year ago
Best ResponseYou've already chosen the best response.30.28 and .28 are same

anonymous

Best ResponseYou've already chosen the best response.0so really .28 or 0.28 because ales is very specific on it

Best ResponseYou've already chosen the best response.3But here, "input" is time spending in texting. Here, you have x = 4 So plug that into best fit line \(y = 0.73x+8.53\)

geerky42

Best ResponseYou've already chosen the best response.3\[y = 0.73(\bf\color{blue}4)+8.53\]
