Write a word problem for x+2=15
_
5
Answer:
x = 13 is the answer for your question
13 + 2 = 15
What is the value of x?
98°
Answer:
x = 139
Step-by-step explanation:
Isosceles triangle.
Let the equal angles = y
y + y + 98 = 180 {Sum of all the angles of triangles}
2y + 98 = 180
2y = 180 - 98
2y = 82
y = 82/2
y = 41
x = 41 + 98 { exterior angles equals the sum of interior opposite angles}
x = 139

If R is the midpoint of QS, find QS. QR=2x+16 RS=5x-17
Answer:
QS = 76
Step-by-step explanation:
Given R is the midpoint of QS, it means the distance from R to each endpoint is equal, that is:
QR = RS
We are given
QR = 2x + 16
RS = 5x - 17
Equating:
2x + 16 = 5x - 17
Subtracting 5x:
2x - 5x + 16 = -17
Simplifying:
-3x +16 = -17
Subtracting 16:
-3x = - 16 -17 = -33
Dividing by -3:
x = 11
Let's find
QR = 2x + 16 = 22 + 16 = 38
The length of QS is double this value: QS = 2*38 = 76
QS = 76

y=-x^3 + 2x2 - 4 at (0, -4)
Find the normal line
Answer:
True
Step-by-step explanation:
I will assume you want to see if (0, -4) is a point on the line.
y = -x³ + 2x² - 4
~Substitute
-4 = -(0)³ + 2(0)² - 4
~Simplify
-4 = -4
Best of Luck!
HURYY I NEED THIS BEFORE 3 !!What is the equation of the line that passes through the point (16.-7) and has slope of m= -3/4 written in point-slope form?
Answer:
The answer is
[tex] \huge y + 7 = - \frac{3}{4} (x - 16) \\ [/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question we have the final answer as
[tex]y + 7 = - \frac{3}{4} (x - 16)[/tex]
Hope this helps you
Find the values of x and y.
Answer: y = 129, x = 51
Step-by-step explanation:
angles 129 and y are corresponding, so they are equal to each other
y and x are supplementary
so, y + x = 180
x = 180 - y = 180 - 129 = 51
Answer:
I belive y has to be at least 133 because it's just a little bit longer than the 229 one.
And x is most likely to be 125 because if you line up 129 with x, x is should be a little smaller so x should be 125
Calculate the dot product of x = (1, −2, 0, 4) is in double-struck R4 and y = (1, 2, 3, 4) is in double-struck R4.
Answer:
the dot product is 13
Step-by-step explanation:
The computation of the dot product is shown below:
Given that
x = (1, −2, 0, 4)
y = (1, 2, 3, 4)
Based on the above information
The dot product is
= (1) (1) + (-2) (2) + (0) (3) + (4) (4)
= 1 - 4 + 0 + 16
= 13
Hence, the dot product is 13
We simply multiplied each of them so that the correct value could come

Last year at a certain high school, 12 students sought the nomination for president of the student body. In how many ways could the voters (student body) rank their first 5 choices
Answer:
95,040 ways
Step-by-step explanation:
The first position has 12 choices
The second has 11 choices (since first is filled)
The third has 10 choices
The fourth has 9 choices
The fifth has 8 choices
So the number of ways they can make the ranking will be;
12 * 11 * 10 * 9 * 8 = 95,040 ways
The number of ways could the voters (student body) rank their first 5 choices is 792 ways.
Calculation of the number of ways:Since Last year at a certain high school, 12 students sought the nomination for president of the student body.
So, here
we use the combination here
[tex]= 12!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\times 7!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\div 5\times 4\times 3\times 2[/tex]
= 792 ways
Therefore, The number of ways could the voters (student body) rank their first 5 choices is 792 ways.

Según datos de una empresa aseguradora de vehículos, dos de cada cinco accidentes son provocados por conductores en estado de ebriedad, ¿cuál es la probabilidad de que tres de nueve accidentes seleccionados al azar hayan sido ocasionados por conductores ebrios?
Answer:
La probabilidad es [tex]0.2508[/tex]
Step-by-step explanation:
Sabemos que según datos de una empresa aseguradora de vehículos, dos de cada cinco accidentes son provocados por conductores en estado de ebriedad. Entonces, si definimos el evento
[tex]A[/tex] : ''Accidente provocado por un conductor en estado de ebriedad''
La probabilidad de este evento es
[tex]P(A)=\frac{2}{5}[/tex] (dato del problema)
Por lo tanto, en cada accidente que ocurre, la probabilidad de que ocurra el evento [tex]A[/tex] es [tex]\frac{2}{5}[/tex] .
Ahora bien, si suponemos cada uno de estos accidentes independientes y con probabilidad de ocurrencia ''p'' constante a lo largo del tiempo, estamos ante la presencia de un proceso Bernoulli.
Dado un proceso de Bernoulli, definimos la variable aleatoria discreta ''[tex]X[/tex]'' como el número de éxitos del proceso Bernoulli para un número fijo de ensayos.
En este caso vamos a definir
[tex]X[/tex] : ''Número de accidentes provocados por conductores en estado de ebriedad de un total de n accidentes''
Se dice que [tex]X[/tex] tiene distribución binomial de parámetros ''n'' y ''p''.
Lo denotamos [tex]X[/tex] ~ Bi (n,p)
En nuestro ejercicio el valor de ''n'' es 9 (son los ensayos que fijamos) y el valor de ''p'' es [tex]\frac{2}{5}[/tex] (definimos como ''éxito'' que el accidente sea provocado por un conductor en estado de ebriedad).
Ahora bien para calcular probabilidad vamos a utilizar la siguiente fórmula :
[tex]P(X=x)=(nCx)p^{x}(1-p)^{(n-x)}[/tex] (I)
'' [tex]P(X=x)[/tex] '' es la probabilidad de que la variable aleatoria [tex]X[/tex] asuma el valor x. En particular, buscamos [tex]P(X=3)[/tex] que es la probabilidad de que de nueve accidentes (fijados), tres sean provocados por conductores en estado de ebriedad.
'' [tex](nCx)[/tex] '' es el número combinatorio definido como
[tex]nCx=\frac{n!}{x!(n-x)!}[/tex]
Reemplazando los datos en la ecuación (I) :
[tex]P(X=3)=(9C3)(\frac{2}{5})^{3}(\frac{3}{5})^{6}=0.2508[/tex]
La probabilidad pedida es [tex]0.2508[/tex]

1. José tiene en su bolsillo un grupo de monedas de 5 y 10 centavos, y hay once
monedas más de 5¢ que las de 10€. Si el total es un dólar.
halla la cantidad de monedas de cada tipo.
Answer:
Hay 14 monedas de 5 centavos y 3 monedas de 10 centavos.
Step-by-step explanation:
Llamemos "c" a las monedas de 5 centavos y "d" a las monedas de 10 centavos.
Hay once monedas más de 5¢ que las de 10¢. La expresión matemática para ello es:
c = d + 11 [1]
El total es 1 dolar. La expresión matemática para ello es:
0,05c + 0,10d = 1 [2]
Si reemplazamos [1] en [2],
0,05(d + 11) + 0,10d = 1
0,05d + 0,55 + 0,10d = 1
0,15d = 0,45
d = 3
Si reemplazamos d = 3 en 1,
c = d + 11 = 3 + 11 = 14
