Answer 10

Still the strangest problem I've ever seen

Answer 11

lets see what ash has to say

Answer 12

From the frequency table
for free family meal= there were 450 tickets
Now
if we have a ticket, then probability of it getting us a family meal is
\[\frac{450}{1500}\]
Mike collected 250 so
he can expect
\[250 \times \frac{450}{1500}= 75\ family\ meals\]

Answer 13

ha! just before u posted tht my dd said the same thing!

Answer 14

wow:)

Answer 15

Well, I must have posted the answer before your dad said anything

Answer 16

I solved it by setting up a proportion:


\[\frac{450}{1500} = \frac{x}{250}\]

x = no of expected free meals

Answer 17

lol u posted it after...can u help me on a easier question? itsdifferent than this

Answer 18

type in page 38/59 and look at question 3

Answer 19

Alvin is hitting on the board every time. He can hit any part of the board. All the case have equal probability
so
We need to find the probability of hitting outside the circle.
Let's first find the area of that portion
Area of square
Side of square= \(2 \times 12\)=24 inches
So Area= 576 inches^2
Area of circle= \(\pi \times r^2\)
r= 12 inches
so
Area of circle=\( 3.14 \times 12^2\)=452.16 inches ^2
Area outside of the circle= 576-452.16=123.84 inches^2
Probability of hitting this area
\[\frac{123.84}{576}= 0.215\]
so it's 0.22

Answer 20

Other than your dad @KC, I was the first to post the answer to the first question.

Answer 21

What the....

there's an @KC ?

Answer 22

i didnt want the answer hero, i wanted how to solve it...to me ash was the first other than my dad:P i never ask for answers

Answer 23

everyone knows tht from my lectured to peepl

Answer 24

Whatever. I posted the answer, then I showed you how I got it. Either way, I posted an answer first. Your dad isn't on Open Study and there's a chance that ash my have deducted from the answer that I posted what the steps were so I win :P

Answer 25

On top of that, I posted an approach to the answer, which I believe is much simpler than ash's or your dad's steps. You should be more appreciative.

Answer 26

it doesnt matter im glad peepl help me..no winning or loosing:/
