The cost of one ticket in Virginia is $8

A System of Linear Equations is when we have two or more linear equations working together.

Given that, 4 movie tickets in Virginia plus 5 movie tickets in Maryland cost $77, Also know that 8 movie tickets in Virginia plus 3 movie tickets in Maryland cost $91.

To find the cost of a ticket in Virginia we will establish a system of linear equations and then solve them,

Let V represents the cost in Virginia that of in Maryland be M

Therefore,

4v+5m = 77.......(i)

8v+3m = 91........(ii)

Multiplying the equation eq(i) by 2 and subtracting eq(ii) from eq(i) [Elimination]

(8v+10m = 154)  - (8v+3m = 91)

7m = 63

m = 9

Put m = 9 in eq(i)

4v+5(9) = 77

4v = 77-45

4v = 32

v = 8

Hence, Each ticket in Virginia and Maryland costs $8 and $9 respectively.

See below for answers and explanations

Step-by-step explanation:

Part A:

f(x) = -x² + 4x - 10

f(2) = -(2)² + 4(2) - 10

f(2) = -4 + 8 - 10

f(2) = 4 - 10

f(2) = -6

Part B:

g(x) = 5x + 1

g(6) = 5(6) + 1

g(6) = 30 + 1

g(6) = 31

Part C:

f(x) = -x² + 4x - 10

f(-1) = -(-1)² + 4(-1) - 10

f(-1) = -1 - 4 - 10

f(-1) = -5 - 10

f(-1) = -15

The population standard deviation of the data is 111.

1. Find the mean of the data:

Mean = (314 + 158 + 482 + 284 + 310 + 281) / 6 = 1029 / 6 = 171.5

2. Find the difference between each data point and the mean:

Feb: (314 - 171.5) = 142.5

Mar: (158 - 171.5) = -13.5

Apr: (482 - 171.5) = 310.5

May: (284 - 171.5) = 112.5

Jun: (310 - 171.5) = 138.5

Jul: (281 - 171.5) = 109.5

3. Square each of the differences:

Feb: (142.5)^2 = 20,312.5

Mar: (-13.5)^2 = 182.25

Apr: (310.5)^2 = 95,822.25

May: (112.5)^2 = 12,656.25

Jun: (138.5)^2 = 19,082.25

Jul: (109.5)^2 = 11,982.25

4. Sum all of the squared differences:

20,312.5 + 182.25 + 95,822.25 + 12,656.25 + 19,082.25 + 11,982.25 = 149,047.5

5. Divide the sum of the squared differences by the number of data points minus one:

149,047.5 / (6 - 1) = 149,047.5 / 5 = 29,809.5

Square root of 29,809.5 = 111 (rounded to the nearest integer)

Therefore, the population standard deviation of the data is 111.

Total interest earned = 68

Total amount collected = 1268

Simple interest is a way to figure out how much interest will be paid on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the following year's principal to compute interest, the principal amount under simple interest remains constant.

Simple interest is a quick and simple approach to figure out how much money has accrued interest. Interest is always applied to the initial principle amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount. Simple interest is one of several forms of interest that banks charge. Now, let's first clarify what a loan is before delving further into the idea of simple interest.

Since nothiong mentioned the interest is considered simple

Total amount = 1200 (principal)

Time = 1 year 5 month = [tex]1\frac{5}{12} = \frac{17}{12}[/tex]

rate = 4 %

Total interest earned = [tex]\frac{1200 * 4 * \frac{17}{12} }{100}[/tex] = 68

Total amount generated = 1200 + 68 = 1268.

Answer:

y=3x-10

Step-by-step explanation:

first, we need to find the slope of line s, as that will determine the slope of line t

the formula for the slope calculated from 2 points is (y2-y1)/(x2-x1)

we can label the points for (3,4) and (2,1)

x1=3

y1=4

x2=2

y2=1

substitute into the formula:

m=(y2-y1)/(x2-x1)

m=(1-4)/(2-3)

m=-3/-1

m=3/1

m=3

the slope of line s is 3

as said above, parallel lines have the same slope, but different y intercepts.

that means that line t will have the same slope as line s (3).

typically, lines are written in the form y=mx+b, where m is the slope and b is the y intercept

here's what is line t so far:

y=3x+b

we need to find b

because the line passes through the point (4,2), we can use it to solve for b

plug 4 in as x and 2 as y

2=3(4)+b

2=12+b

-10=b

so that means that b is -10

therefore the equation for line t is y=3x-10

Hope this helps! Good luck on your assignment!

Answer:

B should be 3 inches long because the area of the square above is 48 inches squared, so that long side is probably 8. B is 3 inches long. As for A, this should be simple. since we know the longer side of the room has the area of 27, we can tell the length(longest side) is 9. 14 minus 9 is equal to 4. A's width is 4 inches long.

Step-by-step explanation:

for the rest, since we know one of the widths is 6 inches, we know that the length of the room with an area of 32 inches is 8. therefore, since 8 times 4 equals the number 32, C is 4 inches long. back to B. since we know that c is 4 inches long and that there is a length of 11 inches, we can tell the longest side of room A is 7. 4 Times 7 equals 28, so B is 28 inches squared.

Whatever the case a quadrilateral has always a sum of interior angles = 360°.

A quadrilateral is a closed shape in geometry that is created by connecting four points, any three of which cannot be collinear. A quadrilateral has four sides, four angles, and four vertices. The word "quadrilateral" is derived from the Latin words "quadra" (four) and "latus" (sides). A quadrilateral may or may not have equal lengths on each of its four sides.

A quadrilateral is a polygon with four sides, four angles, and four vertices. The arrangement of the vertices must be considered whenever a quadrilateral is named. For instance, the following quadrilateral should be referred to as ABCD, BCDA, ADCB, or DCBA. Since they alter the order of vertices in which a quadrilateral is formed, it cannot be called ACBD or DBAC.

1560/100 = 15.6

312/100 = 3.12

Answer: Because they're based off the power of 10.

Step-by-step explanation:

I think the answer is correct because, to make 15.6 to 1560 you just need to multiply by 100, and to get 3.12 to 312 all you have to do is multiply by 100. So if you divided 1560 and 312 which is 5, all you have to do is divide by 100 and you get the same answer thats why its basically considered the same because of the power of tens.

The required point that satisfies each system of equation is (12, -1). Option B is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

To equations are given as,
y = -1/3x + 3 - - - - (1)
y = -3/4x + 8 -- - - - (2)

From equation 1 and 2
-1/3x + 3 = -3/4x + 8
3/4x - 1/3x = 8 - 3
9x - 4x / 12 = 5
5x = 60
x = 12

Now, to evaluate the y ordinate put the above x in equation 1
y = -1/3(12) + 3
y = -4 + 3
y = -1

Thus, the required point that satisfies each system of equation is (12, -1). Option B is correct.

Step-by-step explanation:

Tyler drove 40 miles in one hour.

To find how far Tyler drove in one hour, we need to divide the total distance he traveled (52 21/32 miles) by the total time it took him (1 2/3 hours). To do this, we first need to convert the time to a common denominator, which in this case is 32. We can convert 1 2/3 hours to 32/3 hours by multiplying the numerator and denominator of 2/3 by 32/32.

So, we have:

(52 21/32) miles / (32/3) hour = (52 21/32) miles * (3/32) hour

                                                = (52 21/32) * (3/32)

                                                = (52 213/3232)

                                                = (52 63/32) miles/hour

                                                = 40 miles/hour

Answer:

Para el punto a. tenemos 312 elementos en el espacio muestral

Para el punto b. la probabilidad pedida es [tex]\frac{1}{26}[/tex]

Step-by-step explanation:

Comencemos explicando el principio de multiplicación. Supongamos que se tiene un experimento por etapas, es decir, una primera etapa que se puede llevar a cabo de '' [tex]x_{1}[/tex] '' maneras distintas, una segunda etapa que se puede llevar a cabo de '' [tex]x_{2}[/tex] '' maneras distintas y así sucesivamente hasta una etapa final que se puede llevar a cabo de '' [tex]x_{n}[/tex] '' maneras distintas. La cantidad total de formas de desarrollar todo el experimento se puede calcular como el producto de las distintas maneras en que se puede ejecutar cada etapa :

Formas de desarrollar todo el experimento = [tex]x_{1}x_{2}[/tex] ... [tex]x_{n}[/tex]

Para el punto a. del ejercicio vamos a utilizar este principio para calcular la cantidad de elementos del espacio muestral. La primera etapa del experimento sería el lanzamiento del dado y una segunda etapa el sacar una carta de una baraja de poker (52 cartas distintas). Entonces, para un dado tenemos 6 posibles opciones y cuando sacamos una carta podemos obtener 52 resultados distintos. Por lo tanto ⇒

[tex](6)(52)=312[/tex]

Tenemos un total de 312 elementos en el espacio muestral (todos distintos) y con la misma probabilidad de ocurrencia ya que suponemos que en el dado tenemos la misma probabilidad de obtener un uno, un dos, etc; así como en la baraja tenemos la misma probabilidad de sacar cada una de las cartas.

Para el punto b. utilizaremos el hecho de que estamos frente a un espacio muestral equiprobable y calcularemos la probabilidad del evento ''sale un número par en el dado y un AS en la baraja'' contando los casos favorables a este evento y dividiendo por la cantidad de elementos totales del espacio muestral. Podremos hacerlo de esta manera ya que el espacio muestral es equiprobable. Definimos para ello

[tex]A:[/tex] ''Sale un número par en el dado y un AS en la baraja''

[tex]P(A)=\frac{CasosFavorablesAlEventoA}{CasosTotales}[/tex]

Los casos totales son 312 (calculados en el inciso a.)

Los casos favorables al evento A se pueden escribir utilizando el principio de multiplicación como

[tex](3)(4)=12[/tex]

El 3 es por los tres números pares que podemos obtener del dado (estos números son el dos, cuatro y el seis).

El 4 se debe a la cantidad de ases en una baraja de Póker de 52 cartas (estos son el as de corazones, el as de picas, el as de trébol y el as de diamantes).

Reemplazando en la expresión de [tex]P(A)[/tex] obtenemos :

[tex]P(A)=\frac{12}{312}=\frac{1}{26}[/tex]

Otra forma de haber calculado esta probabilidad es utilizando el hecho de que tirar el dado y sacar una carta de la baraja son dos eventos independientes. Por ende, la probabilidad se puede calcular como el producto de la probabilidad parcial de cada evento. Esto es :

B : ''Sale un número par en el dado''

C : ''Saco un as en la baraja''

[tex]P(B)=\frac{3}{6}=\frac{1}{2}[/tex]

Tres casos favorables a que salga un número par de seis posibles.

[tex]P(C)=\frac{4}{52}[/tex]

Cuatro casos favorables a obtener un as de la baraja de 52 casos posibles.

Ahora escribimos

P ( B ∩ C ) = P(B).P(C)

Por ser B y C dos eventos independientes. Entonces

[tex]P(B)P(C)=(\frac{1}{2})(\frac{4}{52})=\frac{1}{26}[/tex]

Obteniéndose la misma probabilidad ya calculada.
