Its A. 10,000 divided by 250 is 40. Then multiply 40 by 2 and you get 80
10,000 / 250 = 40
40 * 2 = 80
80= A.
Answer:
78.57
Step-by-step explanation:
Radius is 5 feet
Area of circle is pi*r Squared
22/7*5*5
78.57 square feet
<span>The urn contains 2 purple balls and 4 white balls. The player pay $4 for start the game and get $1.5 for every ball drawn until one purple ball is drawn. The maximal revenue would be $7.5 when 4 white balls and 1 purple balls are drawn.
If the purple ball is p and white ball is w, t</span>he possible sample space of drawings are {p, wp, wwp, wwwp, wwwwp}
<span>1. Write down the probability distribution for the player earning
The player earning </span>for each event depends on the number of balls drawn subtracted the ticket price.<span>
p= 2/6
The player earnings would be: 1*$1.5 -$4= - $2.5
wp= (4*2)/(6*5) = 4/15
</span>The player earnings would be: 2*1.5- $4= - $1
wwp= (4*3*2)/(6*5*4)= 1/5
The player earnings would be: 3*$1.5 -$4= $0.5
wwwp= (4*3*2*2)/(6*5*4*3*2)= 2/15
The player earnings would be: 4*$1.5 -$4= $2
wwwwp= (4*3*2*2*1)/(6*5*4*3*2*1) = 1/15
The player earnings would be: 5*$1.5 -$4= $3.5
2. Find its expected value
The expected value would be:
chance of event * earning
You need to combine the 5 possible outcomes from the number 1 to get the total expected value.
Total expected value= (1/3 * - 2.5)+ (4/15*-1) + (1/5*0.5) + (2/15 *2) + ( 1/15 *3.5)=
(-12.5 -4 + 1.5 + 4 + 3.5) /15= -$7.5
This game basically a rip off.
The additive inverse of 7/2 would be -7/2 (option B) Since its. opposite !
A)is the additive inverse of C) ; C) is the additive inverse of A) (not your answer)
B. is the additive inverse for this problem (7/2) so thats how we found that this is your answer (answer)
D is the same thing for the problem (7/2) (not your answer)
7/2 isnt the additive inverse for 7/2 because they are the SAME not the opposite.
+ = - (Positive = negative)
- = + (negative = positive)
