Answer:
Correspondencia entre conjuntos:
a) Inyectiva: es cuando a cada imagen en el conjunto de llegada le corresponde un único origen, es decir, a distintos elementos del conjunto inicial, les corresponden distintos elementos del conjunto final.
b) Sobreyectiva: es si todos los elementos del conjunto final tienen al menos una correspondencia del conjunto inicial
c) Biyectiva: es cuando la correspondencia es inyectiva y sobre inyectiva a la vez
Correspondencia unívoca : es una correspondencia donde cada elemento del conjunto origen se corresponde con solo un elemento del conjunto de llegada.
Correspondencia biunívoca es cuando a cada elemento del conjunto origen se corresponde con solo un elemento del conjunto llegada, y viceversa

Compare the dimensions of the prisms. How many times greater is the surface area of the green prism than the surface area of the blue prism?
I will ONLY give a brainliest to whoever answers the questions CORRECTLY!
Answer:
The surface area of the green prism is 6.25 times greater than the surface area of the blue prism.
Step-by-step explanation:
The surface area of both prisms consists of six rectangles: top, base, front, back, left side and right side. In terms of surface area, top=base, front=back and left side=right side, so the total surface area for each prism is:
2(base area)+2(back area)+2(side area)
=2((base area)+(back area)+(side area))
Area of blue prism = 2((base area)+(back area)+(side area))
=2((4*2)+(4*10)+(2*10))
=2(8+40+20)
=2(68)
=136 cm²
Area of green prism = 2((base area)+(back area)+(side area))
=2((10*5)+(25*10)+(25*5))
=2(50+250+125)
=2(425)
=850 cm²
850cm² is 6.25 times greater than 136cm² (850/136=6.25), so therefore, the surface area of the green prism is 6.25 times greater than the surface area of the blue prism.

Students in an environmental science class raised money to buy plants for a community garden. The students raised money by selling regular cupcakes for $2.00 each and gluten-free cupcakes for $3.00 each. The number of regular cupcakes sold was determined to be 2 times the number of gluten-free cupcakes sold. If a total $350 was raised through cupcake sales over a three-week period, how many cupcakes were sold altogether
Answer:
50 gluten-free cupcakes and 100 regular cupcakes.
Step-by-step explanation:
Let's define the variables:
R = number of regular cupcakes sold
G = number of gluten-free cupcakes sold
The total amount of money raised then is:
M = R*$2.00 + G*$3.00
We also know that:
The number of regular cupcakes sold was 2 times the number of gluten-free cupcakes sold.
then:
R = 2*G
And we also know that the amount of money raised is $350
Then we have the equations:
R = 2*G
R*$2.00 + G*$3.00 = $350
We can replace the first equation into the second one, so we have only one variable:
(2*G)*$2.00 + G*$3.00 = $350
Now we can solve this for G.
G*$4.00 + G*$3.00 = $350
G*$7.00 = $350
G = $350/$7.00 = 50
G = 50
50 gluten-free cupcakes where sold.
And using the equation:
R = 2*G = 2*50 = 100
We can conclude that 100 regular cupcakes were sold.

Step-by-step explanation:
The cardinality of a set is the total number of elements in the set
Given the set
A = {a,e,i,o,u}
The total number of letters we have in the set is 5 i.e. a, e, i ,o and u. Hence the cardinality of the set A is 5. This can also be written as n(A) = 5

What is the area of this semicircle if the radius is 6m?
Una caja A contiene 5 bolas blancas y 4 negras; otra caja B contiene 3 bolas blancas y 5 negras. Se trasladan 3 bolas de la caja A a la B, y se saca una bola de la caja B. Cual es la probabilidad de que esta sea blanca?
The probability of drawing a white ball from box B is 7/8 or approximately 0.875 (87.5%).
Let's calculate the probability of drawing a white ball from box B after transferring 3 balls from box A to box B.
Given:
Box A contains 5 white balls and 4 black balls.
Box B contains 3 white balls and 5 black balls.
After transferring 3 balls from box A to box B, we need to consider two scenarios:
The ball drawn from box B comes from the 3 transferred balls.
The ball drawn from box B comes from the original balls in box B.
Let's calculate the probability for each scenario and then sum them to obtain the total probability.
After transferring 3 balls from box A to box B, box B will contain 6 balls (3 white and 3 black), while box A will contain 2 white balls and 4 black balls.
The probability of drawing a white ball in this scenario is 3/6, as there are 3 white balls out of a total of 6 balls in box B after the transfer.
In this scenario, we consider that the ball drawn from box B comes from the original balls in box B, meaning it was not transferred from box A.
The probability of drawing a white ball in this scenario is 3/8, as there are 3 white balls out of a total of 8 balls in box B before the transfer.
Now let's sum the probabilities of both scenarios to obtain the total probability:
Total Probability = (Probability of Scenario 1) + (Probability of Scenario 2)
= (3/6) + (3/8)
= 1/2 + 3/8
= 4/8 + 3/8
= 7/8
