Answer:

The expected value of the raffle will be $1000 and the money obtained from selling tickets will be(4x400=$1600).

Step-by-step explanation:

First prize: $300

Second prize: 200x2=$400

3x100=$300

300+400+300

=$1000

The expected value of the raffle will be $1000 and the money obtained from selling tickets would be equal to $1600.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

400 raffle tickets were sold for $4 each.

The one first prize winner will receive $300, and two people will each receive a second prize of $200.

There will be three $100 winners.

First prize = $300

Second prize = 200 x 2

=$400

So, the expected gross​ winnings:

3x100=$300

300+400+300

=$1000

[tex](5y + 1)^{2} - (2(y - 1))^{2} [/tex]

Step-by-step explanation:

1) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y - 1 ).

[tex](5y + 1) ^{2} - (2(y - 1)) ^{2} [/tex]

2) Use multiplication Distributive Property: (xy)^a = x^a y^a.

[tex](5y + 1)^{2} - {2}^{2} (y - 1 {)}^{2} [/tex]

3) Simplify 2² to 4.

[tex](5y + 1 {)}^{2} - 4(y - 1 {)}^{2} [/tex]

4) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y-1).

[tex](5y + 1 {)}^{2} - (2(y - 1))^{2} [/tex]

B

Step-by-step explanation:

it is important to note that 40/8 = 5.

A real number is one that can be found on the number line, and 5 can be.

A rational number can be made by dividing two integers (40 by 8 in this case).

5 is a whole number since it does not have a decimal/fractional part

an integer is a whole number which is positive/negative (5 is positive in this case)

Answer:

54 feet

Step-by-step explanation:

Perimeter of a rectangle = 2 × (length + breadth)

The perimeter of Edwin's garden is 36 feet :

36 = 2 x (length + breadth)

divide both sides by 2 to determine the sum of the length and breadth of Edwin's garden

36/2 = (length + breadth)

18 = (length + breadth)

Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden

The dimensions of Tony's garden is :

(4 + l) + (5 + w) = 9 + l + w

Where :

l = length

w = width

The sum of the length and breadth of Tony's garden would be 9 feet more than that of Edwin

Sum of Edwin's garden = 9 + 18 = 27

Perimeter of Edwin's garden = 27 feet x 2 = 54 feet

Answer:

A.  The median height of the sample must be between 59 and 63 inches.

B. Another random sample of 20 students is likely to have a mean between 57 and 65 inches.

E.  Elena would be more likely to get an accurate estimate of the mean height of the population  by sampling 40 people instead of sampling 20 people.

Step-by-step explanation:

The mean absolute deviation shows the variation in a given data set. It can be determined by calculating the mean of the absolute value of the initial mean and each data set. It describes how spread out the data set are.

With respect to Elena's sampling, the mean absolute deviation is 2. This shows that there is little variation among the data set.

The estimate becomes more accurate if she increase the sample size. Thus options A, B and E are appropriate.

∠RPQ = 53°

Step-by-step explanation:

∠SPR and ∠RPQ are complementary, meaning that they add up to 90°. So,

∠SPR + ∠RPQ = 90°

We know that ∠SPR = 37°, so

37° + ∠RPQ = 90°

∠RPQ = 90° - 37°

∠RPQ = 53°

B. negative infinity < x < positive infinity

Step-by-step explanation:

When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for all exponential functions, including this one.

Answer:

La ecuación de la recta es [tex]y = -6\cdot x +23[/tex].

Step-by-step explanation:

Para construir la ecuación de la recta podemos utilizar un punto contenido en la recta y su pendiente. En primer punto, hallamos el punto con la resolución del siguiente sistema de ecuaciones lineales:

[tex]x+4\cdot y = 0[/tex] (1)

[tex]x-3\cdot y = 7[/tex] (2)

La solución del sistema de ecuaciones es [tex](x,y) = (4,-1)[/tex].

Por Geometría Analítica, sabemos que la Ecuación de la Recta en su forma explícita es:

[tex]y = m\cdot x + b[/tex] (3)

Donde:

[tex]x[/tex] - Variable independiente.

[tex]y[/tex] - Variable dependiente.

[tex]m[/tex] - Pendiente.

[tex]b[/tex] - Intercepto.

Si sabemos que [tex](x,y) = (4,-1)[/tex] y [tex]m = -6[/tex], entonces el intercepto de la recta es:

[tex]b = y-m\cdot x[/tex]

[tex]b = 23[/tex]

Ahora, la ecuación de la recta es [tex]y = -6\cdot x +23[/tex].

Answer:

B

Step-by-step explanation:

if you multiply m by 2 you get 260we now want to subtract this from 360 to get 100 then we divide that by 2 to get angle n∠BEF= 50°.

We know angle k∠EBF= 90° so we now end up with adding angle ∠BEF with ∠EBF  to get 140 to get angle x we subtract 140 from 180 to get 40. x=40°. so B is the correct answer
