Tickets for a raffle costs
9. There were 709 tickets sold. One ticket will be randomly selected as the winner, and that person wins
1300. For someone who buys a ticket, what is the Expected Value (the mean of the distribution)?
If the Expected Value is negative, be sure to include the "-" sign with the answer. Express the answer rounded to two decimal places.
Expected Value = $
Answers
For a ticket buyer who pays $9 per ticket, the expected value of the raffle is $-7.17.
What is the expected value?The expected value is the product of the probability of an event occurring and the value of the observed occurrence.
As a probability-weighted value, the expected value is computed by multiplying the sum of the values by the probability of winning.
It is the mean of a random variable.
The cost per raffle ticket = $9
The number of tickets sold = 709
The winning value = $1,300
The probability of winning the raffle by one ticket = 1/709
Therefore, the expected value is $-7.17 [($1,300 x 1/709) - $9], that.

There are six pizzas there are 36 players on the team. If each member has one slice and each pizza has eight slices how much pizza in fraction form will be left over.
Answers
There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.
To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.
Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.
Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.
To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.
Therefore, there will be 12 slices of pizza left over.
To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.
If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

An ant colony is built by 200 ants. The number of ants triples each week. How many ants will be in the colony at the end of the eighth week?
Answers
N = N0 * 3^t
where N is the final number of ants, N0 is the initial number of ants, 3 is the rate of growth (since the number of ants triples each week), and t is the number of weeks.
We are given that there are initially 200 ants, so N0 = 200. We want to find N at the end of 8 weeks, so t = 8. Substituting these values into the formula, we get:
N = 200 * 3^8
N = 200 * 6561
N = 1,312,200
Therefore, at the end of the eighth week, there will be 1,312,200 ants in the colony.

A company makes about 2.5 × 1 0 7 2.5×10 7 tablets in a year. The company spends about $20 to make each tablet. About how much money, in dollars, does the company spend making tablets each year?
Answers
The company spends making tablets each year, you can multiply the number of tablets by the cost per tablet so the company spends about $500 million making tablets each year.
Why is it referred to as money?Its origins lie in the Latin word moneta, which was given to the Roman goddess Juno, at whose temple or close by, or both, the Romans first started minting coins approximately 300 BCE.
We may multiply the quantity of tablets produced by the cost of producing each tablet to see how much money the company spends annually making tablets:
Total cost = Production of tablets x Price per tablet
Number of tablets produced =\(2.5 × 10^7\)
Cost per tablet = $20
Therefore, the total cost = \(2.5 × 10^7 × $20 = $5 × 10^8\)
As a result, the corporation spends over $500 million annually producing tablets.

Budgeted sales for the period were 50,000 units of Product Blaster. A recession last year meant
that the market for the product declined by 5%.
Required:
(a) Calculate the following variances.
(i) Sales volume variance.
Answers
The Sales Volume Variance of the car manufacturer for the twelve-month period is $96,000.
What is the sales volume variance?The sales volume variance measures the financial impact of not meeting or exceeding the budgeted sales for a period.
It can be computed by finding the difference between actual and budgeted sales quantities and then multiplied by the unit selling price.
Data and Calculations:Budgeted sales units = 50,000
Actual sales units = 48,000
Sales price per unit = $60
Actual sales revenue = $2,904,000
Budgeted sales revenue = $3,000,000 ($60 x 50,000)
Sales volume variance = $96,000 ($3,000,000 - $2,904,000)
Thus, the Sales Volume Variance is $96,000.

The length of the side GF is equal to 0.96 according to Pythagoras's Theorem.
Given angle ∠E = 16°
Length of side GE = 3.5
Also the given angle is right angled triangle. So ∠F = 90°.
Now we need to find the length of side GF.
Use Pythagoras's theorem to find the length GF.
Formula: \(C^{2} =A^{2} +B^{2}\)
i.e., \(GE^2=GF^2+EF^2\)
Now, according to trigonometric rules, sinФ= opposite /hypotenuse
cosФ = adjacent / hypotenuse
tanФ = opposite / adjacent
Now, sum of all angles = 180°
So ∠G = 180°-90°-16° = 74°
∠G = 74°
Now, sin 16° = x/3.5 = opposite / hypotenuse
x = 0.275 x 3.5
x= 0.96
Therefore, the length of the side GF (x) is equal to 0.96.
