Answer: 0.5507
Step-by-step explanation:
Given: The time between sightings of speeders by a radar system is represented by the continuous random variable X, which follows a cumulative distribution function

If we convert 12 minutes into hours, it equals
hours or 0.2 hours.
To find the probability of waiting less than 12 minutes:

Thus, the probability we are looking for is: 0.5507
Al establecer un sistema de ecuaciones lineales, se determina que el total de obreros que contrató el ingeniero civil es 50.
Para descubrir cuántos obreros fueron contratados, se debe formular un sistema de ecuaciones lineales con dos ecuaciones y dos incógnitas, de la siguiente manera:
(1)
(2)
Donde:
M: representa la incógnita correspondiente al capital del ingeniero
x: simboliza la incógnita que denota el total de obreros
De la ecuación (1) podemos deducir:
(3)
Utilizando la ecuación (3) en la ecuación (2) podríamos calcular el valor de x (número de obreros):



El monto inicial del ingeniero, según la ec (3), sería:

Por lo que, el número de obreros contratados por el ingeniero es 50.

The given details include: Height of the rectangular prism, h = 3 units, Surface area of the prism, A = 52 sq units. We need to determine the volume of the prism. The volume of a rectangular prism can be calculated using the formula: l = length and b = breadth. Given that the surface area of the prism, A = lb, we have it equal to 52 sq units. Consequently, the volume is 156 cubic units.
Hello!

Solution:
The ratio is expressed as 4 to 1.
Add these parts together.
4 + 1 equals 5.
Now divide.
150 divided by 5 results in 30.
Next, multiply to find Ivan's share.
30 multiplied by 4 gives us 120.
30 multiplied by 1 equals 30 for Tanya.
Verify.
120 plus 30 totals 150.
Then subtract.
120 minus 30 equals 90.

Answer:
Ivan possesses £90 more than Tanya!
