two thousand ticketa are sold at a raffle for a chance to win a gaming computer system worth $1800. the tickets are sold for $2 each. if a person buys only one ticket what is the expected value for that ticket?round to the nearest cent if necessary
Answer:
The expected value of the ticket is -$1.10
Step-by-step explanation:
Here, we want to find the expected value of the ticket sales
We start by calculating the probabilities
The probability that someone wins the system is 1/2000
The probability that a person loses the system is 1999/2000
So the expected value will be;
(1/2000 * 1,800) - (1999/2000 * 2)
= 0.9-1.999 = -1.099
To the nearest cent, this is -1.10
April invests $30,000, part at 6.5% annual interest and the balance at 4.2% annual interest. How much is invested at each rate if April receives a 1-year interest payment of $1662.50?
Answer:
$17500 at 6.5% and $12500 at 4.2%Step-by-step explanation:
Given
Let x be the amount invested at 6.5%Then (30000 - x) is invested at 4.2%The equation for the interest:
x*6.5/100 + (30000 - x)*4.2/100 = 1662.500.065x + 1260 - 0.042x = 1662.500.023x = 1662.50 - 12600.023x = 402.5x = 402.5/0.023x = 17500So $17500 invested at 6.5% and $12500 at 4.2%

Chance wants to wish his cousin a happy birthday at 9:00am CST. Chance lives in Texas and his cousin lives in Ohio. What time will it be at his cousins's house when Chance calls to say happy birthday?
Answer:
10:00 am EST in Ohio
Step-by-step explanation:
Using the 50 States Time zones attached in the image below.
Chance who lives in Texas has a Time zone of CST (central standard time), while his cousin who lives in Ohio has a Time zone of EST(eastern standard time).
So if it is 5 pm in CST, it will be 6 pm in EST.
Given that;
Chance wants to wish his cousin in Ohio at 9:00 am CST, then the time it will be at his cousin's house when Chance calls to say happy birthday will be:
9:00 am + 1 = 10 :00 am EST in Ohio

If fighting is sure to result in victory, then you must fight!
Sun Tzu said that, and I'd say he knows a little more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor.
Then, he used his fight money to buy two of every animal on earth, and then he herded them onto a boat and then he beat the cra p out of every single one.
And from that day forward any time a bunch of animals are together in one place it's called a 'zoo'!

solve for x 7x-3=5x+5=
Answer:
x=4
Step-by-step explanation:
7x-3=5x+5
2x-3=5
2x=8
x=4
The value of x in the expression 7x-3=5x+5 is 4
Given
7x-3=5x+5
Here,
The equation is linear in variable x .
7x-3=5x+5
7x - 5x - 3 = 5
2x-3=5
2x = 5 + 3
2x=8
x = 8/2
x=4
Thus the value of x is 4 .

Solve for v.
12/5 = 6v
solve step by step and have a well explanation.
if you get this correct and solve this question step by step with a good explanation then i will mark you brainliest!
Answer:
v = 2/5 Or v = 0.4
Step-by-step explanation:
12/5 = 6v
to isolate V divide both sides by 6
(12/5) : (6)= 6v : (6)
For the left side because there is a fraction when you devide you change it into multiplication, flipping the addent and quotient so you’ll have
12/5 * 1/6 (you semplify the cross numbers) you’ll have 2/5
on the right side the 6 cancel each other. Because 6/6 = 1. so you will have 1v which is v.
2/5 = v
or decimal form
0.4 = V

Answer: 17
Step-by-step explanation:
Each side has one line on it indicating each side is equal therefore 5y-3= 4y+1. Once you put them equal to each other you solve for y. You start by isolating the variable by inverse operations so you add 3 to both sides which leaves 5y=4y+4 and then you subtract 4y from both sides leaving y=4. Now that you found the value of y you input that value into one of the expression for one of the sides and solve. 5(4)-3= 17

The dew point in degrees Fahrenheit can be calculated with the formula DP = T (100 - RH), where DP is
the dew point, T is the dry-bulb temperature, and RH is the relative humidity. Which of these is the equation
solved for RH?
RH = 100 -
(T-DP)
RH = 100 – 2 (DP-1)
RH = 100 – (DP-1)
RH = 100 – 25 (T-DP)
Answer:
B
Step-by-step explanation:
I took that same test and i didthe practice test. Believe me.
The equation that can be used to solve for RH is 25/9(DP-T) - 100
Given the formula for the dew point in degrees, Fahrenheit expressed as
DP = T - 9/25(100 - RH)To solve for the value of RH, we will make RH the subject of the formula;
DP = T - 9/25(100 - RH)Subtract T from both sides:
DP - T = 9/25(100 - RH)Multiply both sides by 25
25(DP - T) = 9(100 - RH)
25(DP - T) = 900 - 9RH
25(DP - T) - 900 = 9RH
RH = 25/9(DP-T) - 100
Hence the equation that can be used to solve for RH is 25/9(DP-T) - 100

Solve the problem below by finding a common denominator.
5/6-2/5
Answer:
I know how to this in one of two ways and I'm not sure if they're correct but anything to help.
5/6-2/5 would get you 1/3 because if you cross multiply and cross out factors that can go into each you cant pretty much get that answer. ( i think)
or
the common denominator would be 30 multiply 5 by 5 and 2 by 6. 25-12 is 13. How I was taught was find a number that both denominators can go into then multiply by that number. So 6*5= 30 so you would multiply 5 by 5 to get 25.
Hope I explained this well, I don't really think so.
