La edad actual de José es de 30 años.

Para resolver este problema, primero debemos establecer ecuaciones basadas en la información proporcionada. Llamemos "x" a la edad actual de José y "y" a la edad actual de Ana. Según la primera condición, la edad de Ana es la mitad de la edad de José, por lo que podemos escribir la ecuación: y = (1/2)x.

La segunda condición nos dice que dentro de 10 años, sus edades serán dos tercios de sus edades actuales. Esto se puede expresar como: (x + 10) * (2/3) = y + 10.

Reemplazando el valor de y en la segunda ecuación con la primera ecuación, obtenemos: (x + 10) * (2/3) = (1/2)x + 10.

Sphenathi and the other matriculants must travel at an average speed of approximately 107 km/h to reach Uptington by 09:45.

To determine the average speed at which Sphenathi and the other matriculants must travel to reach Uptington by 09:45, we need to calculate the time available for the journey and the distance between the two locations.

The time available is from 07:25 to 09:45, which is a total of 2 hours and 20 minutes. We need to convert this time to hours by dividing by 60:

2 hours + 20 minutes / 60 = 2.33 hours

Now, let's calculate the distance between Bloemfontein and Uptington. Suppose the distance is 'd' kilometers.

We can use the formula for average speed: average speed = distance / time

In this case, the average speed should be such that the distance divided by the time is equal to the average speed.

d / 2.33 = average speed

Now, let's assume that Sphenathi and the other matriculants must travel a distance of 250 kilometers to reach Uptington. We'll substitute this value into the equation:

250 / 2.33 = average speed

To find the average speed to the nearest km/h, we'll calculate the result:

average speed ≈ 107.3 km/h

Therefore, Sphenathi and the other matriculants must travel at an average speed of approximately 107 km/h to reach Uptington by 09:45.

The probability of the event that all three are blue is 1/455 or 0.0022

In probability theory, the probability of an event is a measure of the likelihood that the event will occur. It is a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event can be expressed as a decimal, a fraction, or a percentage.

Probability is used to quantify the uncertainty associated with a random event. It is based on the idea that if an experiment is repeated many times under the same conditions, the proportion of times the event of interest occurs will be close to the probability of that event.

The probability of an event can be calculated using the following formula:

Probability of an event = Number of favorable outcomes / Total number of possible outcomes

In this problem, we can define our variables.

Total number of possible outcomes = 15

P(All three are blue) = (3/15) * (2/14) * (1/13)

P(All three are blue) = 1/455

P(all three are blue) = 0.0022

Suppose that g is a function from A to B and F is a function from B to C.

a)  If fog is onto, then f must also be onto.

Assume that f∘g  is onto. Let c ∈ C . Since f∘g is onto, then is a ∈A such that c = (f∘g) (a) by the definition of onto function. By the definition of function composition, c = f(g(a)). Let b = g(a). This b belongs to B  and is such that c = f(b) . Therefore, for every c ∈ C , there is b ∈ B such that c = f(b). By the definition of onto function, f is onto.

(b) If fog is one-to-one, then g must also be one-to-one.

Let \(a_1,a_2\) ∈ A such that \(g(a_1)=g(a_2)\). Then

(f∘g)\((a_1)\)  = \(f(g(a_1))=f(g(a_2))\) = (f∘g)\((a_2)\)

Since f∘g is one - to - one, \(a_1=a_2\). Therefore, for all \(a_1,a_2\) ∈ A such that

\(g(a_1)=g(a_2)\), \(a_1=a_2\). By the definition  of one-to-one function, g  is one-to-one. \(b_1=g(a_1)=g(a_2)\)

(c)  If fog is a bijection, then g is onto if and only if f is one-to-one.

Assume that f∘g  is a bijection.

Assume that g is onto. Let \(b_1,b_2\) ∈ B such that \(f(b_1)=f(b_2)\). Since g is onto,  by the definition of onto function, there are \(a_1,a_2\) ∈A such that

\(b_1=g(a_1) and b_2=g(a_2)\) We have

(fog)\((a_1)\) = \(f(g(a_1) )=f(b_1)\)

= \(f(b_2) =f(g(a_2))= (fog)(a_2)\)

Since fog is a bijection, it is one-to-one, hence \(a_1=a_2\), and

\(b_1=g(a_1)=g(a_2)=b_2\)

Both representations are equivalent and describe the same function.the function rule for this table is:   f(x) = -1/2 x 2

The slope or gradient of a line is a number that describes both the direction and the steepness of the line. A slope of a line is the change in y coordinate with respect to the change in x coordinate.

To write a function rule for a given array, we need to determine how the values ​​in the output column (y) relate to the values ​​in the input column (x).

Looking at the given data, we notice that the output values ​​decrease by 1 every time the input value increases by 2. This suggests that the function is linear and that we can use the slope-intercept form of a linear equation to represent it. .

The slope-intercept form of a linear equation is y = mx b, where m is the slope and b is the y-intercept. In this case, the slope m is -1/2 because the output values ​​decrease by 1 every time the input values ​​increase by 2. The y-intercept b is 2 because the output value is 2 when the input value is 0.

Therefore, the function rule for this table is:

f(x) = -1/2 x 2

where x is the input value and f(x) is the output value.

Alternatively, we can also represent the function in table entries, for example:

f(0) = 2

f(2) = 1

f(4) = 0

f(6) = -1

Both representations are equivalent and describe the same function.

The solution set for the inequality is x < 2. Among the given options, the value that is included in the solution set is 0.

To determine which value is included in the solution set for the inequality statement -3(x-4) > 6(x-1), we need to solve the inequality for x.

Starting with the given inequality:

-3(x - 4) > 6(x - 1)

First, distribute -3 and 6 to the terms inside the parentheses:

-3x + 12 > 6x - 6

Next, combine like terms by subtracting 6x from both sides and adding 6 to both sides:

-3x - 6x > -6 - 12

-9x > -18

To isolate x, divide both sides of the inequality by -9. Remember that when dividing by a negative number, we need to reverse the inequality sign:

x < (-18) / (-9)

x < 2

Therefore, the solution set for the inequality is x < 2. Among the given options, the value that is included in the solution set is 0.
