Answer:

Davide is 10 years old.

L'età di Davide è 10.

Step-by-step explanation:

The average ages of Aldo, Bruno, Carlo, and Davide amount to 16 years.

Let’s denote:

x for Aldo's age.

y for Bruno's age.

z for Carlo's age.

w for Davide's age.

The average for all four is 16 years.

This gives us:

Excluding Davide, the average age of the other three is 18. Therefore:

Substituting into the original equation:

Hence, Davide’s age is indeed 10.

L'età di Davide è 10.

Response:

We define a line L.

In a two-dimensional space, a line can be expressed as follows:

y = a*x + b

where 'a' denotes the slope and 'b' represents the y-intercept.

To determine the slope for a line passing through points (x1, y1) and (x2, y2), the formula is:

a = (y2 - y1)/(x2 - x1).

Using one of these points will help to find the value of 'b'.

Once we have the line's equation:

y = a*x + b

we can substitute in a specific point (x, y)

to verify if the equation holds true. If it does, that point lies on the line L.

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
