find the distance between the points (-2,8) and (7,13) on a corrdiante plane
Answer: d = √(5² + 9²) = √106, or approximately 10.3 units.
The point (0, 5) lies on a circle with the center at (0, 0). What is the area of the circle?
Line s passes through the points (3,4) and (2,1).line t passes through the point (4,2) and is parallel to line s.
What is the equation for line t
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

Total interest earned = 68
Total amount collected = 1268
What is simple Interest ?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.

Unit sales for new product ABC have varied in the first seven months of this year as follows: Feb 285 Mar Apr May Jun Jul Month Jan 314 158 482 284 310 281 Unit Sales What is the (population) standard deviation of the data? Please round your answer to the nearest integer. Note that the correct answer will be evaluated based on the full-precision result you would obtain using Excel
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)

solve for the missing side length in this triangle
Answer:
10 and 24units
Step-by-step explanation:
Pythagoras' TheoremPythagoras' Theorem applies to right angle triangles with the formula:
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
where c is the longest side, with a and b the shorter ones (interchangable)
SolutionWith the parameters given from the question and the formula given as well, we can find the value of x and therefore the side lengths.
By Pythagoras' Theorem,
[tex] {26}^{2} = ( {5x)}^{2} + ( {12x)}^{2} \\ 676 = 25 {x}^{2} + 144 {x}^{2} \\ 169 {x}^{2} = 676 \\ {x}^{2} = 676 \div 169 \\ {x}^{2} = 4 \\ x = \sqrt{4} \\ = 2[/tex]
Now we can find the side lengths.
[tex]5x = 5(2) = 10units \\ 12x = 12(2) = 24units[/tex]
Therefore the side lengths are 10 and 24 units.

Técnica de conteo en estadística 6. Regla multiplicativa. Para el experimento de un lanzamiento de dado y sacar una carta de una baraja de Poker (52 cartas). a. Calcule la cantidad de elementos del espacio muestral. b. Calcula la probabilidad de que salga un número par en el dado un AS en la baraja.
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.

You know that 4 movie tickets in Virginia plus 5 movie tickets in Maryland cost $77. You also know that 8 movie tickets in Virginia plus 3 movie tickets in Maryland cost $91. How much does a ticket in Virginia cost?
The cost of one ticket in Virginia is $8
What is a system of linear equations?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.

What are simultaneous linear equations?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
