we know that
total cards=10
even numbers=2,4,6,8,10 -----> 5 cards
the probability that getting an even number is
P=5/10
The probability that getting an odd number
n 1 -----> P=1/10
n3 ----> P=1/10
n5 ---> P=1/10
n7 ----> p=1/10
n 9 ---> P=1/10
The expected value is equal to
EV=(1)(1/10)+(3)(1/10)+(5)(1/10)+(7)(1/10)+(9)(1/10)-(4.20)(5/10)
EV=(25/10)-(21/10)
EV=4/10
EV=$0.40
<h2>The expected value is $0.40</h2>
Part B
Jane can expect to win money after playing the game many times
the answer is
<h2>Jane can expect to gain money</h2><h2>She can expect to win $0.40 per draw</h2>
Answer:
She will get back 44 dollars in change
Step-by-step explanation:
Lets calculate how much she spent
2 tshirts = 2 *28 = 56
1 jean = = 120
4 pairs socks = 80
-------------------------------
total 256
She gives the clerk 300 dollars
300-256 =44
She will get back 44 dollars in change
Answer:
Step-by-step explanation:
A. The regular cost is 55 per person. Using the given variable definitions, that cost can be expressed as ...
y = 55x
__
B. The party special cost is 46 per person, with an added fee of 45. That cost can be expressed as ...
y = 46x +45
_____
As you know, the cost of a purchase is the product of the cost of an item and the number of items. Here, the cost of entry is the cost of the item of interest, and the number of persons needing entry is the number of items. The party special has the addition item of a private room, so its cost is added to the total for the party special.
Answer:
Step-by-step explanation:
<u>The vertices are:</u>
- K(-12,2), L(-7,12), J(3,-10)
<u>Find the sides using distance formula:</u>
- KL =
≈ 11.18 - LJ =
≈ 24.17 - KJ =
≈ 19.21
<u>Find perimeter:</u>
- P = KL + LJ + KJ
- P = 11.18 + 24.17 + 19.21 = 54.56 units
