Answer:
f(x)= 25(1 + 0.20)^t
Step-by-step explanation:
The formula- f(x)= a(1+r)^x
a= initial amount (25)
r= growth rate (20%... 0.20)
x= # of times (we don't have that in here)
When you plug in the values, you get
f(x)= 25(1 + 0.20)[tex]{t}[/tex]

Given that the student chosen was a female, find the probability that the student chose invisibility as their superpower. P\left( \text{invisibility }| \text{ female} \right)=P(invisibility ∣ female
Answer:
[tex]P(Invisibility | Female) = \frac{2}{3}[/tex]
Step-by-step explanation:
Given
See attachment for two-way table
Required
Determine [tex]P(Invisibility | Female)[/tex]
This is calculated using the following formula for conditional probability:
[tex]P(Invisibility | Female) = \frac{n(Invisibility \& Female)}{n(Female)}[/tex]
From the attached table
[tex]n(Invisibility \& Female) = 32[/tex]
[tex]n(Female) = 48[/tex]
So, the equation becomes:
[tex]P(Invisibility | Female) = \frac{32}{48}[/tex]
Simplify
[tex]P(Invisibility | Female) = \frac{32/16}{48/16}[/tex]
[tex]P(Invisibility | Female) = \frac{2}{3}[/tex]
Los boletos para la obra de teatro "Los Miserables" cuestan 15 dólares para adultos y 5 dólares para estudiantes. Si se vendieron 227 boletos y los ingresos fueron de 2,375 dólares. ¿Cuántos boletos de cada clase se vendieron?
Answer:
Se vendieron 124 boletos para adultos y 103 boletos para estudiantes.
Step-by-step explanation:
Un sistema de ecuaciones es un conjunto de ecuaciones con las mismas incógnitas. Un sistema de ecuaciones lineales es un sistema de ecuaciones en el que cada ecuación es lineal.
En otras palabras, un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.
Resolver un sistema de ecuaciones significa encontrar valores para las incógnitas que hace verdadera cada una de las ecuaciones.
En este caso, las variables son:
x: cantidad de boletos para adultos.y: cantidad de boletos para estudiantes.Los boletos para la obra de teatro "Los Miserables" cuestan 15 dólares para adultos y 5 dólares para estudiantes. Si se vendieron 227 boletos y los ingresos fueron de 2,375 dólares, se puede expresar el siguiente sistema de ecuaciones:
[tex]\left \{ {{x+y=227} \atop {15*x+5*y=2375}} \right.[/tex]
Se elige resolver por el método de sustitución, cuyo primer paso consiste escoger una ecuación y despejar una incógnita en términos de la otra incógnita. En este caso, se despeja la variable "y" de la primer ecuación, obteniendo:
y=227 - x
A continuación se sustituye la expresión hallada en la otra ecuación, para obtener una ecuación con una incógnita y, luego despejar esa incógnita. En este caso, reemplazando la anterior expresión en la segunda ecuación del sistema de ecuaciones:
15*x + 5*(227 -x)= 2375
Resolviendo:
15*x + 5*227 - 5*x= 2375
15*x + 1135 - 5*x= 2375
15*x - 5*x= 2375 - 1135
10*x= 1240
x= 1240 ÷10
x= 124
Finalmente se sustituye el valor hallado en la expresión y=227 - x para despejar la incógnita restante:
y=227 - 124
y= 103
Entonces se vendieron 124 boletos para adultos y 103 boletos para estudiantes.

Step-by-step explanation:
You and a friend are playing a game of chance. Every time you roll (using a fair die) a 1, 2, 3, or 4, you are successful, and your friend will pay you $1. Every time you roll a 5 or 6, you must pay your friend $2. If 65% of your rolls are successful and 35% of your rolls are unsuccessful, how much money do you expect to have won/owe by the end of the game?
You owe 41 cents
You have won 5 cents
You owe 5 cents
You have won 41 cents
Answer:
you owe $5
Step-by-step explanation:
65% wins means $65
35% losses means -$70
Answer:
You owe 5 cents.
Step-by-step explanation:
(the amount of money won)(the number of successful rolls)+(the amount of money lost)(the number of unsuccessful rolls)=expected value
65% of rolls are successful which means that 13/20 of the rolls are successful (simply convert to a fraction).
35% of the rolls are unsuccessful which means that 7/20 of the rolls are unsuccessful.
Using the equation above we can use,
(1)(13/20)+(-2)(7/20)
to find the expected value.
(1)(13/20)+(-2)(7/20)=0.05

Combine like terms in 3x + 2y + 2x + 4y + 1
Answer: 5x+6y+1 is the answer
Step-by-step explanation: to combine like terms that have to have the same variable so you can add them so for example you have 3x+2x which is equal to 5x then 2y+4y which is = to 6y and you also have 1 that isn't adding to anything because the others have variables
Answer:
5x + 6y + 1
Step-by-step explanation:
You are also simplifing and collecting the like terms. 3x + 2x = 5x. So that goes first as it appears first in the equation. Secondly, 2y + 4y = 6y, and that adds on to the previous answer. So far we have 5x + 6y. Now just add te 1, as it has no like value.

The point P (x,y) lies on the terminal side of an angle 0= 195 in standard position. What are the signs of the value of x and y
Answer:
When we have a point (x, y), the angle that defines this point in polar coordinates is given by:
Tan(θ) = y/x
In this case, we know that θ = 195°
Then replacing that, we get:
Tan(195°) = y/x
0.268 = y/x
Now, there is a problem, we have a single equation and two variables.
So we will get:
y = (0.268)*x
This equation defines all the possible values that x and y could take such the angle in standard position is 195°.
So we only can conclude that:
x and y have the same sign.
For a given value of x, the correspondent y-value is:
y = (0.268)*x
Find the arc length of the partial circle. Use 3.14 for pi and enter your answer as a decimal.
Answer:
However, if you're trying to find the arc length of a partial circle, it's not the same as the circumference of the same circle wholly. You need to find out the circumference of the whole circle first before you can find the arc length (or the circumference of the partial circle).

∠2 ≅ ∠ because they are corresponding angles of parallel lines cut by a transversal. ∠5 ≅ ∠ by the Vertical Angles Theorem.
*see diagram in the attachement below
Answer:
∠2 ≅ ∠6 because they are corresponding angles of parallel lines cut by a transversal. ∠5 ≅ ∠8 by the Vertical Angles Theorem.
Step-by-step explanation:
We are required to find the angle that is congruent to <2 and the angle that is congruent to <5.
Already, we are given the reasons to justify the answers we get.
Thus:
<2 has matching corner as <6. Hence they are corresponding angles
<5 and <8 are vertical angles having the same vertex and are directly opposite each other. Therefore, based on the vertical angles theorem, <5 ≅ <8

what is the slope of this image
Answer:
50
Step-by-step explanation:
Alright, so two of the points are: (0,25) (1,75)
Now we line them up:
(0,25)
(1, 75)
And, 0 to 1 has "1" as a difference.
That'll go on the bottom.
25 to 75 has a "50" difference.
That goes on top.
And then we get the slope of 50.
Hope this helped! :)
Answer:
Slope = 50
Step-by-step explanation:
[tex]\frac{y2-y1}{x2-x1}[/tex]
(1,75) (2,125)
125 - 75/2-1
125-75 = 50
2-1 = 1
50/1 = 50

Simi bought a study table for $ 9000. She sold it at a profit of 20%. How much profit did she make? What is the selling price?
Answer:
cost price of a table=$9000
profit%=20%
Let profit be x
to find profit use formula,
profit%=profit/cost price*100
20%=x/$9000*100
20*$9000=100x
$180000/100=x
$1800=x
Now to find selling prie os a table use formula,
cost price +profit
$9000+$1800
$91800
therefore selling price of a table is $91800

Which equation represents a parabola opening to the right with a vertex at the origin and focus at (9,0) A. X = - 1/36y^2 B. X = - 1/6y^2 C. X = 1/36y^2 D. X = 1/6y^2
Answer:
Option C: x = (1/36)*y^2
Step-by-step explanation:
A horizontal parabola is written as
x = f(y) = a*y^2 + b*y + c
If a is positive, the parabola opens to the right.
if a is negative, the parabola opens to the left.
And the vertex of the parabola has the y-value:
y = -b/2a
and the x value
x = f(-b/2a)
For our parabola, we know that:
Opens to the right:
Then the only options left are:
C) x = (1/36)*y^2
D) x = (1/6)*y^2
Because in both cases b = 0, both of the equations have the vertex in the point (0, 0).
Now let's see wich one has a focus at (9, 0)
If the vertex of our equation is:
(h, k)
Then the focus will be:
(h + a, k)
Where a is the directrix of the equation.
Here we know that the vertex is (0, 0) and the focus is (9, 0)
Then:
(0 + a, 0) = (9, 0)
The directrix is 9.
And the directrix is such that:
(x - h)^2 = 4*a*(y - k)
Replacing the values of h and k (both are zero) we get:
x^2 = 4*a*y
And we know that: a = 9
x^2 = 4*9*y
x^2 = 36*y
if we isolate y, we get:
(1/36)*x^2 = y
This is option C.
Then the correct option is C.
