The expected winning and the value of that prize, which gives an expected winning is c. $3.13 per ticket.

The expected winnings per ticket in the raffle can be calculated by adding the products of the probability of the expected value of winning each prize. The predicted wins per ticket may be computed as the total of each prize's value multiplied by its probability of winning, i.e.

Expected winnings per ticket

= (1/800) × $400 + (4/800) × $200 + (12/800) × $125 + (30/800) × $60 + (753/800) × $0

If we condense the equation, we obtain:

Calculating the total wins anticipated per ticket

= $0.50 + $1.00 + $1.88 + $0.75 + $0

Expected winnings per ticket = $3.13

Therefore, if you buy a ticket, the expected winnings per ticket are $3.13.

Answer:  \(2\sqrt{5}\\\\\)

To get that answer, we apply the distance formula

\(d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-8-(-6))^2 + (-2-2)^2}\\\\d = \sqrt{(-8+6)^2 + (-2-2)^2}\\\\d = \sqrt{(-2)^2 + (-4)^2}\\\\d = \sqrt{4 + 16}\\\\d = \sqrt{20}\\\\d = \sqrt{4*5}\\\\d = \sqrt{4}*\sqrt{5}\\\\d = 2\sqrt{5}\\\\d \approx 4.472136\\\\\)

As an alternative, you could plot the two points on the same xy grid, and then form a right triangle. Afterward, apply the pythagorean theorem and you should get the same result as shown above.

This is a right triangle so angle x and the adjacent red angle both form 90 degrees. Since the red angle is a equal angular triangle. It measures 60 degrees so 60+x=90 x=30

In the regression equationp, the letter x represents the independent variable. (C)

In a regression equation, we typically have a dependent variable (often denoted as y) and one or more independent variables (often denoted as x₁, x₂, etc.). The regression equation represents the relationship between the dependent variable and the independent variable(s).

The independent variable, represented by the letter x, is the variable that is assumed to influence or affect the dependent variable. It is the variable that is controlled or manipulated in the analysis. The regression equation estimates the effect of the independent variable(s) on the dependent variable.

For example, in a simple linear regression equation y = mx + b, where y is the dependent variable and x is the independent variable, the coefficient m represents the slope of the line (the change in y for a unit change in x), while the constant term b represents the y-intercept.

Maria's amount of land first exceeds Lucia's amount of land after 3 months.

To solve this problem, we need to find out when Maria's total amount of land first exceeds Lucia's total amount of land. Let's start by writing out the formulas for the amount of land each woman has after n months

Lucia's land after n months = 11 + 5n

Maria's land after n months = 6 × 1.4^n

Now we want to find the month, n, when Maria's amount of land first exceeds Lucia's amount of land. So we need to solve the following inequality

6 × 1.4^n > 11 + 5n

We can solve this inequality by using a trial-and-error approach or by using a graphing calculator. Here's one way to solve it using trial-and-error

Let's start by plugging in n = 1 and see if Maria's land is greater than Lucia's land:

6 × 1.4^1 = 8.4

11 + 5 × 1 = 16

Since 8.4 < 16, we know that Maria's land is not greater than Lucia's land after 1 month.

Now let's try n = 2

6 × 1.4^2 = 11.76

11 + 5 × 2 = 21

Since 11.76 < 21, we know that Maria's land is still not greater than Lucia's land after 2 months.

Let's keep trying larger values of n until we find the first month when Maria's land is greater than Lucia's land:

n = 3

6 × 1.4^3 = 16.384

11 + 5 × 3 = 26

Since 16.384 > 26, we know that Maria's land is greater than Lucia's land after 3 months.

EXPLANATION

Triangle DEF is:

We want to know the measure of angle D, knowing the side lengths DE (the hypotenuse of the triangle) and FD (the adjacent side to angle D). We can use the cosine of D:

In summary, fy(a,b) is the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

The given expression represents the partial derivative of f(x, y) with respect to y, evaluated at (a, b):

fy(a,b) = lim┬(y→b)⁡〖[f(a,y) - f(a,b)]/(y - b)〗

Geometrically, this partial derivative represents the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

To see why this is the case, consider the following argument:

Let L be the limit in the expression given above.

Let h = y - b be the change in the y-coordinate from b to y.

Then, we can rewrite the limit as:

fy(a,b) = lim┬(h→0)⁡〖[f(a,b + h) - f(a,b)]/h〗

This expression represents the average rate of change of f(x, y) with respect to y over the interval [b, b + h].

As h approaches 0, this average rate of change approaches the instantaneous rate of change, which is the slope of the tangent line to the surface defined by f(x, y) at the point (a, b) in the y-direction.

Therefore, fy(a,b) is the partial derivative of f(x, y) with respect to y, evaluated at (a, b).

Answer:

t=\(-\frac{2log 2 (3)}{3}\)

Step-by-step explanation:

\(52^{-3t}\)=45

Use the rules of exponents and logarithms to solve the equation.

5*\(2^{-3t}\)=45

Divide both sides by 5.

2^-3t=9

Take the logarithm of both sides of the equation.

log(2-^3t)=log(9)

The logarithm of a number raised to a power is the power times the logarithm of the number.

-3t log(2)=log(9)

Divide both sides by log(2).

-3t = \(\frac{log(9)}{log(2)}\)

By the change-of-base formula

-3t=\(log_{2}\) (9)

Divide both sides by −3

t= \(-\frac{2log 2 (3)}{3}\)

The  smallest such $n$ is $12$.

To solve the problem, we can start by expanding $(n+r)^3$ and approximating it by ignoring the term $r^3$, since $r$ is small.

We  then want to find the smallest positive integer $n$ such that there exists a positive real number $r$ less than $1/1000$ satisfying the equation. We can try different values of $n$ starting from $n=1$ and incrementing by $1$ until we find a value of $n$ that works.

By  testing a few values, we find that $n=12$ works, giving us $1728 + 1296r + 324r^2$, which is less than $(12+1/40)^3$. Therefore, the smallest such $n$ is $12$.

Answer:

vertex = (3, - 8 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

\(x_{vertex}\) = - \(\frac{b}{2a}\)

y = x² - 6x + 1 ← is in standard form

with a = 1 and b = - 6 , thus

\(x_{vertex}\) = - \(\frac{-6}{2}\) = 3

Substitute x = 3 into the function for y

y = 3² - 6(3) + 1 = 9 - 18 + 1 = - 8

Probabilities (at least 13 graduates) = 0.29858

The variable is binomial, which means that it can only have two possible outcomes (in this case, either a student will graduate or they will drop out). The probability of at least 13 students out of 15 graduating is calculated by adding the probability of exactly 13 students graduating and the probability of exactly 14 students graduating:

P(at least 13 graduate) = P(exactly 13 graduate) + P(exactly 14 graduate)

To calculate the probability of exactly 13 students graduating, use the binomial formula:
P(X = 13) = (15 choose 13) * (0.105)13 * (0.895)2

The calculation for P(X = 13) is: (15 choose 13) * (0.105)13 * (0.895)2 = (15!/13!(15-13)!) * (0.105)13 * (0.895)2 = (15 * 14 / 1 * 1) * (0.00155) * (0.80505) = 0.16437

Similarly, to calculate the probability of exactly 14 students graduating, use the binomial formula:
P(X = 14) = (15 choose 14) * (0.105)14 * (0.895)1

The calculation for P(X = 14) is: (15 choose 14) * (0.105)14 * (0.895)1 = (15!/14!(15-14)!) * (0.105)14 * (0.895)1 = (15 / 1) * (0.01462) * (0.895) = 0.13421

Finally, add the probabilities together to find the probability of at least 13 students graduating.
P(at least 13 graduates) = P(exactly 13 graduate) + P(exactly 14 graduate)
P(at least 13 graduates) 0.16437 + 0.13421 = 0.29858, rounded to three decimal places.

Step-by-step explanation:

The diagonal of a rectangle creates the hypotenuse of a right triangle. Use the Pythagorean theorem, a2 + b2 = c2, where a = 30 ft and b = 24 ft, to calculate the length of the fence c.

a2 + b2 = c2

302 + 242 = c2

900 + 576 = c2

1476 = c2

38.42 ≈ c

The fence should be about 38 feet long. Isn't it strange to divide a garden in half diagonally with a fence? It doesn't seem to serve the purpose of keeping intruders out. It doesn't seem to serve any purpose, really.

The volume of the stone is 1032 cm³.

The volume of the stone can be calculated using the formula V = lwh. Here, l = 10 cm, w = 24 cm, and h = 2.7 cm. Therefore, the volume of the stone is V = 10 x 24 x 2.7 = 648 cm³.

The volume of the water in the container is calculated using the formula V = lwh. Here, l = 10 cm, w = 24 cm, and h = 7 cm. Therefore, the volume of the water in the container is V = 10 x 24 x 7 = 1680 cm³.

The difference between the volume of the water and the volume of the stone is the volume of the water displaced by the stone, which is V = 1680 - 648 = 1032 cm³. Therefore, the volume of the stone is 1032 cm³.
