A lottery has a very large number of tickets, one in every 500 of which entitles the purchaser to prize. Find the minimum number of tickets the agent must sell to have 95% chance of selling at least one prize winning ticket. ​

Part A:  At her current rate, the distance Amy can ride her bike within 12 minutes is A. 1.6 miles.

Part B: Sebastian can ride his bike for  C: 7.5 miles in 1 hour.

Part C: The time it will take for one to wait is B: Amy will have to wait 1.5 minutes for Sebastian.

Part A:

To find the distance Amy can ride her bike in 12 minutes, we set up a proportion based on her current rate.

Amy's rate: 4 miles / 30 minutes = x miles / 12 minutes

Cross-multiplying:

30x = 4 * 12

30x = 48

Dividing both sides by 30:

x = 48 / 30

x ≈ 1.6

So, Amy can ride her bike at 1.6 miles in 12 minutes.

Part B:

To find the distance Sebastian can ride his bike in 1 hour, convert the time to minutes first.

1 hour = 60 minutes

Sebastian's rate: 3 miles / 24 minutes = x miles / 60 minutes

Cross-multiplying:

24x = 3 * 60

24x = 180

Dividing both sides by 24:

x = 180 / 24

x ≈ 7.5

Therefore, Sebastian can ride his bike at 7.5 miles in 1 hour.

Part C:

Amy's home to  Park = 3 miles,

Park to Sebastian's home = 3 miles.

Amy's rate = 4 miles in 30 minutes, equivalent to 1 mile in 7.5 minutes.

Sebastian's rate = 3 miles in 24 minutes, equivalent to 1 mile in 8 minutes.

Then, we estimate the time it takes for each to cover a distance of 3 miles.

Amy:

Time = Distance / Rate = 3 miles / (2/15 miles/minute)

= 3 * (15/2) minutes

= 22.5 minutes

Sebastian:

Time = Distance / Rate = 3 miles / (1/8 miles/minute)

= 3 * 8 minutes

= 24 minutes

Since Amy= 22.5 mins and Sebastian takes 24 mins,

24 - 22.5 = 1.5

Hence, Amy will have to wait 1.5 minutes for Sebastian.

The measures of the marked angles in the figure are:

x = 0.8°

6x + 8° = 12.8°

x + 12° = 12.8°

We have that:

x + 12° and 6x + 8°.

We equate the expression: 6x + 8° = x + 12°

We then  solve for x:

6x - x = 12° - 8°

5x = 4°

We then divide  both sides by 5:

x = 4° / 5

x = 0.8°

We get the  measure of the marked angle for

Answer: Thats a Trapezoid

Step-by-step explanation:

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.

From the first equation, we can rearrange to get x = 12 + y.

Substituting that into the second equation, we get y^2 = 5(12 + y - 2) = 50 + 5y.

This simplifies to y^2 - 5y - 50 = 0.

Using the quadratic formula, we can solve for y to get y = 10 or y = -5.

Therefore, two possible values of y are 10 and -5.

The three trigonometric ratios are the sine, the cosine and the tangent, and they are defined as follows:

The sum of the internal angle measures of a triangle is of 180º, hence the measure of angle H is given as follows:

m < H + 25 + 90 = 180

m < H = 65º.

Regarding the angle of 25º, we have that 15 is the opposite side, while y is the adjacent side, hence the measure of y is given as follows:

tan(25º) = 15/y

y = 15/tangent of 25 degrees

y = 32.2.

Applying the Pythagorean Theorem, the value of c is obtained as follows:

The expected value of the investment is $600,000.

The expected value of the investment is calculated by multiplying the possible outcomes by their respective probabilities and summing them up. In this case, the possible outcomes are a success or a failure, with probabilities of 0.3 and 0.7 respectively.

If the company succeeds, the investment will be worth $2,000,000. If it fails, the investment will be worth $0. Therefore, the expected value is:

(0.3 x $2,000,000) + (0.7 x $0) = $600,000

This means that the expected value of the investment is $600,000.

Since the expected value of the investment is positive, Mr. Sharp should invest the $100,000.

The given table represents a linear function with a constant rate of change of 2. Option D is the right answer.

To determine if the table represents a linear function and calculate the rate of change, let's examine the given values:

x   | y

-----------

1   | 3

2   | 5

3   | 7

4   | 9

By looking at the y-values, we can observe that for every increase of 1 in x, the corresponding y-value increases by 2. This indicates a constant rate of change, suggesting that the table represents a linear function.

To calculate the rate of change, we can use the formula:

[tex]\[\text{{Rate of Change}} = \frac{{\text{{Change in y}}}}{{\text{{Change in x}}}}\][/tex]

Taking any two points from the table, let's choose (1, 3) and (2, 5):

[tex]\[\text{{Rate of Change}} = \frac{{5 - 3}}{{2 - 1}} = \frac{2}{1} = 2\][/tex]

The table provided exhibits a linear function with a constant rate of change. As the x-values increase by 1 from [tex]1[/tex] to [tex]4[/tex], the corresponding y-values increase by [tex]2[/tex] from [tex]3[/tex] to [tex]9[/tex]. This consistent change in y for each unit change in x indicates a linear relationship between the variables.

The rate of change, also known as the slope of the function, is determined by the ratio of the change in y to the change in x. In this case, the rate of change is [tex]2[/tex], meaning that for every increase of [tex]1[/tex] in [tex]x[/tex], the y-value increases by 2.

Thus, the table represents a linear function with a rate of change of [tex]2[/tex].

The annual deposit for John for total amount of annuity is A = $ 29,060.29

Given data ,

To determine the annual deposit amount needed for John to have a total of $500,000 by the time he retires, we can use the formula for the future value of an ordinary annuity:

FV = P * [(1 + r)^n - 1] / r

Where FV is the future value, P is the annual deposit, r is the annual yield (interest rate), and n is the number of years.

In this case, we are given:

FV = $500,000

r = 5% = 0.05

n = 25 years

Substituting these values into the formula, we have:

$500,000 = P * [(1 + 0.05)^25 - 1] / 0.05

And , the value of P is

P = ($500,000 x 0.05) / [(1.05^25) - 1]

P ≈ ($25,000) / (1.858734... - 1)

P ≈ ($25,000) / 0.858734...

d. The answer to Kiran's question can be written using mathematical notation as:

Kiran can be able to take out a maximum of $6.25 every month to make sure that he has at least $25 in the account a year from that time now.

Since the inequality  is -12x + 100 ≥ 25,  the term -12x stands for the amount Kiran takes out each month. It is seen as a negative value because it stands for the monthly withdrawals from the  said account.

b. To find values of x that would work for Kiran,  it can be done by:

-12x + 100 ≥ 25.

-12x + 100 ≥ 25

So, subtract 100 from both sides:

-12x ≥ 25 - 100

-12x ≥ -75

Then divide both sides by -12 ( dividing by a negative number changes the inequality sign) Hence it will be:

x ≤ (-75) / (-12)

x ≤ 6.25

So, any value of x that is less than or equal to 6.25.

The end behavior of a polynomial with positive leading coefficient is either "up-up" or "down-down" depending on the degree of the polynomial the end behavior of a polynomial with negative leading coefficient is either "up-down" or "down-up" depending on the degree of the polynomial.

Actually, the end behavior of a polynomial refers to the behavior of the function as the input variable (usually x) approaches positive or negative infinity.

The end behavior of a polynomial is determined by the degree and leading coefficient of the polynomial.

If the degree of the polynomial is even and the leading coefficient is positive, then the end behavior is as follows:

As x approaches negative infinity, the graph of the polynomial approaches the x-axis from above (the arrows point in opposite directions).

As x approaches positive infinity, the graph of the polynomial approaches the x-axis from below (the arrows point in opposite directions).

If the degree of the polynomial is even and the leading coefficient is negative, then the end behavior is as follows:

As x approaches negative infinity, the graph of the polynomial approaches the x-axis from below (the arrows point in opposite directions).

As x approaches positive infinity, the graph of the polynomial approaches the x-axis from above (the arrows point in opposite directions).

If the degree of the polynomial is odd and the leading coefficient is positive, then the end behavior is as follows:

As x approaches negative infinity, the graph of the polynomial goes down to negative infinity (the arrows point in the same direction).

As x approaches positive infinity, the graph of the polynomial goes up to positive infinity (the arrows point in the same direction).

If the degree of the polynomial is odd and the leading coefficient is negative, then the end behavior is as follows:

As x approaches negative infinity, the graph of the polynomial goes up to positive infinity (the arrows point in the same direction).

The star is approximately 3.04×10^17 kilometers or 32.2 light-years away.

We have,

We can use the inverse square law to find the distance to the star:

Luminosity / (4π(distance)²) = Apparent brightness

Rearranging this formula to solve for the distance, we get:

distance = √(Luminosity / (4π (Apparent brightness)))

Plugging in the given values, we get:

distance = √(8.0 × 10^{26} / (4π (1.5 × 10^{-12}))

Simplifying this expression, we get:

distance = 3.04 × 10^{20} meters

Converting this distance to kilometers, we get:

distance = 3.04 × 10^{17} kilometers

To convert this distance to light-years, we divide by the speed of light in kilometers per year:

distance = (3.04 × 10^{17}) / (9.46 × 10^{12})

Simplifying this expression, we get:

distance = 32.2 light-years
