Answer:

0.139

Step-by-step explanation:

Number of pedestrians that were intoxicated 81

Number of pedestrians that were not intoxicated 225

Number of drivers that were intoxicated 51

Number of drivers that were not intoxicated 552

Total number of deaths 952

Probability of pedestrians intoxicated or driver intoxicated is

81/952 + 51/952 = 132/952 = 0.139

Answer:

0.3927

Step-by-step explanation:

Given

Pedestrian intoxicated

Yes (81) (51) ---- (132)

No (225) (552) --- (777)

Total: (306) (603) --- (909)

Let P(P) = the probability that the pedistrian was intoxicated

Let P(D) = T probability that the diriver was intoxicated

To calculate P(D or P)?

P(D or P) is given as P(D) + P(P) - P(P and D)

P(P) = 306/909

P(D) = 132/909

P(P and D) = 81/909

P(P or D) = 306/909 + 132/909 - 81/909

P(P or D) = 357/909

P(P or D) = 0.3927

A car travels at a constant speed of 60 miles per hour. The distance, d, the car travels in miles is a function of time, t, in h
scZoUnD [109]

The equation of distance traveled by the car is d(t) = 60 · t, for t ≥ 0.

<h3>What is the equation of the distance travelled by a car?</h3>

In accordance with the statement, car travels in a <em>straight</em> line at <em>constant</em> speed. The distance traveled (d), in miles, is equal to the product of the speed (v), in miles per hour, and time (t), in hours:

d(t) = v · t     (1)

If we know that v = 60 mi/h, then the equation of distance traveled by the car is d(t) = 60 · t, for t ≥ 0.

<h3>Remark</h3>

The statement is incomplete and complete form cannot be found. Then, we decided to complete the statement by asking for the equation that describes the distance of the car.

Three schools are located at points A, B, and C. The school district wants to locate its new stadium at a location that will be
dangina [55]

I have attached the image showing the location of the three schools.

Answer:

Should be built at the centroid of the triangle formed by points A, B and C.

Step-by-step explanation:

From the attached image, we see that if we join the 3 points by a straight line, they will form a triangle.

Now, to get a location that will be roughly the same distance from all 3 schools, it means a point that is equal to each of 3 vertex of the triangle.

The point that is equal to each vertex of a triangle is known as "Centroid".

Now, to find this centroid, we will add up the (x, y) coordinates of the 3 vertex and divide by 3.

For example;let's assume ;A has a coordinate of (x1, y1) ; B has a coordinate of (x2, y2) ; C has a coordinate of (x3, y3).

The coordinates of the centroid will be;

[(x1 + x2 + x3)/3], [(y1 + y2 + y3)/3]
