Answer:
$160
Step-by-step explanation:
28 bags cost $140
4 bags will serve 5 guests
Number of bags that will serve 40 guests:
(40 /5) * 4bags
8 * 4 bags = 32 bags of candy
A bag of candy will cost :
$140 / 28 = $5
Cost of 32 bags :
Cost per bag * 32
$5 * 32 = $160
The lottery's anticipated worth is $80.
Given that,
The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.
A) EV=125*.2+100*.3+50*.5=$80
The lottery's anticipated worth is $80.
The expected value is obtained by multiplying each result by its likelihood.
The expected value of the lottery is then calculated by adding up all of these.
This is what we have: ;;
125(0.2) + 100(0.3) + 50(0.5) (0.5)
= 25 + 30 + 25 = $80
B) This is the formula for variance is shown in figure :
So, we can calculate the variance as follows:
.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975
C) A risk-neutral person would pay $80 or less to play the lottery.

0.58
Step-by-step explanation:
because they are the Decimals
Answer:
So scientific notation would be 5 x 10 ^7, and standard would be 50,000,000
Step-by-step explanation:
The 7 means you move the decimal to the right 7 times, meaning you add 7 zeros.
