When a 757 passenger jet begins its descent to the Ronald Reagan National Airport in Washington, D.C., it is 3900 feet from the

Illusion [34]

Answer:

B. 37,310.4 ft

Step-by-step explanation:

It's a rectangle triangle, and we have the height (3900 ft) and the opposite angle (6 degrees), and we're looking for the hypotenuse (distance traveled) length.

In a rectangle triangle, there's a relation between those elements: the sinus of the angle.

$sin(angle) = \frac{Opposite side}{Hypotenuse}$

So, if we want to calculate the hypotenuse...

$Hypotenuse = \frac{Opposite side}{sin(angle)}\ = \frac{3900 ft}{sin(6)}\ = \frac{3900 ft}{0.1045}\ = 37310.4117 ft$

A survey shows that 30% of the residents of a particular town read the morning paper 25% read the afternoon paper, and 10% read

shusha [124]

Answer:

A) 0.20

B) 0.06

Step-by-step explanation:

From the question above we have the following information;

30% of the residents of a particular town read the morning paper

Probability (of the residents that read morning paper) = 0.3

25% read the afternoon paper

Probability (of the residents that read afternoon paper) = 0.25

10% read both

Probability (of the residents that read both) = 0.10

A. One resident is randomly selected. What is the probability that this person reads only the morning paper?

Probability( that this person reads only the morning paper) = Probability (of the residents that read morning paper) - Probability (of the residents that read both)

= 0.30 - 0.10

= 0.20

B. Given that a random resident reads the morning paper, what is the probability that this resident also reads the afternoon paper?

Probability( that this resident also reads the afternoon paper) = Probability (of the residents that read morning paper) × Probability (of the residents that read afternoon paper)

= 0.30 × 0.20

= 0.06

icang [17]

Given:

The pair of end points: (3,-8) and (3,-1).

To find:

Whether the given pair of endpoints lies on the same horizontal or vertical line.

Solution:

If the x-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same vertical.
