Answer:

Ana tiene 27 años mientras que Carlos, tiene 69 años

La suma de las edades es: 27+69 = 96

La suma de las cifras de este resultado es 9+6 = 15

Step-by-step explanation:

Vamos a hacer una linea temporal para ubicarnos en tiempo.

AÑO 2021, Ana tiene una edad A mientras que Carlos tiene una edad C

15 años para adelante

AÑO 2036, la edad de Carlos es el doble de la de Ana

C = 2A

Si nos vamos 6 años para atrás

AÑO 2015, la edad de Carlos es el triple de la de Ana

C = 3A

Como de 2015 a 2036 pasan 21 años, podemos plantear que

La edad de Carlos + 21  va a ser 2 veces la edad de Ana, traducido:

C + 21 = 2A, pero en 2015, ya sabemos que la edad de Carlos es el triple de la de Ana, entonces:

3A + 21 = 2A. Si despejamos:

3A - 2A = -21

A = |21|  Ésta es la edad de Ana. (Ponemos valor absoluto porque una edad no puede ir negativa.

Si Ana en 2014 tiene 21 años, Carlos tiene 63 (el triple) por lo que sumamos 6 años y llegamos al presente:

En 2021, Ana tiene 27 años (21+6), mientras que Carlos tiene 69 (63+6). Edades actuales.

Nos corremos 15 años al futuro, por lo que llegamos al año 2036.

Carlos pasa a tener 84 años (69+15) y Ana, 42 (27+15) donde verificamos que la edad de Carlos, es el doble que la de Ana, 84/42 = 2.

Finalmente la suma de las edades es: 27+69 = 96

La suma de las cifras de este resultado es 9+6 = 15

Answer:4/13

Step-by-step explanation:

Number of yellow chicks = 8

Number of black and white chicks = 6

Total number of chicks = 8+6 = 14

The probability of the first yellow chick escaping will be 8 out of 14.

The probability of the second yellow chick escaping will be 7 out of 13 since there'll be 13 chicks left after the first yellow excaped.

Therefore, the probability that both chicks were yellow will be:

= 8/14 × 7/13

= 4/7 × 7/13

= 4/13

Therefore, the probability is 4/13.

Answer:

n(U)=30

n(H)=15

n(G)=18

n(H ∪ G)'=5

n(H ∪ G)=n(U)-n(H ∪ G)'

             =30-5=25

So ,n(H ∩ G)=n(H)+n(G)-n(H ∪ G)

                    =15+18-25=8

Therefore, 8 students take both subjects.

A set is a mathematical model for a collection of diverse things. The total number of students who who take both History and Geography is 8.

A set is a mathematical model for a collection of diverse things; it comprises elements or members, which can be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.

Given that there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of these subjects. Therefore, we can write the following values,

Now, the number of students who take at least one of the two subject can be written as,

Students who choose at least one subject

= Total students - Students who take neither of the subject

n(H ∪ G) = n(U) - n(H ∪ G)'

n(H ∪ G) = 30 - 5

              =25

Further, the total number of students who who take both the subjects can be written as,

Students who take both the subjects = Students who take History + Students who take Geography - Students who choose at least one subject

n(H ∩ G) = n(H) + n(G) - n(H ∪ G)

n(H ∩ G) = 15 + 18 - 25

n(H ∩ G) = 8

Hence, the total number of students who who take both History and Geography is 8.

Answer:

12cm

Step-by-step explanation:

The area of a kite is the product of the diagonals divided by 2:

A = (d1 * d2)/2

You can substitute what we have:

120 = (20 * d2)/2

And solve.

240 = 20 * d2

d2 = 12cm

The length of the other diagonal is 12cm.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

SOLUTION:

Step 1:

In this question, we are given the following:

The area of a kite is 120. One of the diagonals is 20.

What is the length of the other diagonal?

Step 2:

The details of the solution are as follows:

we know that,

The area of a kite is the product of the diagonals divided by 2:

A = (d1 * d2)/2

You can substitute what we have:

120 = (20 * d2)/2

And solve.

240 = 20 * d2

d2 = 12cm

CONCLUSION:

The length of the other diagonal = 12 cm.

The value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

We have given data in the table.

As we know, the formula for the correlation is given by:

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

After plugging the value, we will get the value of r:

r = -0.953

Thus, the value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.

Step-by-step explanation:

that is correct and right answer.

The sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A)  The sequence diverges is correct.

A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.

The sequence can be defined as the systematic way of representing the data that follows a certain rule of arithmetic.

It is given that:

The sequence:

3/4, 4/5, 5/6, 6/7, . . .

AS we know, the convergent sequence occurs when, as n approaches infinity, you arrive at a final and constant term through a number of terms.

Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.

The nth term of the sequence

a(n) = 2+n/3+n

Applying divergence test:

The sequence diverges

Thus, the sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A)  The sequence diverges is correct.
