The probability that a family to visit the beach also will travel the mountains is 0.33.

A Venn diagram is a graph that uses circles to represent relationships between objects or finite groups of objects. Circles that intersecting share properties, but circles that do not overlap do not.

Please see the Venn diagram.

P(B) [the entire blue circle] = 0.6 is the probability of such a family vacationing there at beach.

P(B∩M) [the red/blue intersecting intersection of two circles] = 0.2 is the possibility of a family taking a vacation in both locations.

Using the property of independent event: Two events are considered independent if the incidence of one does not affect the likelihood of occurrence of the other.

As, occurrence of  family visiting the beach will also visit the mountains is an independent event. Thus,

The formula for the independent event is;

P(B | M) = P(B∩M)/P(B)

P(B | M) = 0.2/0.6

P(B | M) = 0.33

Therefore, the probability of the occurrence that family visiting the beach will also visit the mountains is 0.33.

The two numbers other than 1 and 1 are 2 and 3 finally get the 34 means 7 th term in the sequence.

The Fibonacci numbers, sometimes known as Fn in mathematics, are a series of numbers. Each number in the Fibonacci sequence is composed of the sum of the two numbers before it. Typically, the sequence begins with 0 and 1.

from the question

Let take the first term as 2.

and second term as 3.

2 + 3 = 5

3 + 5 = 8

5 + 8 = 13

8 + 13 = 21

13 + 21 = 34

21 + 34 = 55

34 + 55 = 89

The Fibonacci sequence includes the numbers 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 and so on.

The ratio of pencils to all the item on the desk is 1 : 10

According to Gary,

    Number of pencils on the desk = 4

    Number of markers on the desk = 12

The required value of constant of variation, k does not exist for which x and y vary directly..

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of constant of variation

When a quantity varies directly with others, then we have a relation, y = kx, where k is the constant of the proportion      —-- 1

Given relation is  y + 3 = -3 x

y = -3 x - 3

y = -3(x + 1)

45,90,180,360, .... is a geometric sequence. The next two terms are 720, 1440.

In an arithmetic sequence, the difference between two subsequent terms is constant. This difference between two subsequent terms is usually called common difference (d), and its value is:

d = a(n) - a(n-1)

Where a(n) is the nth term and a(n-1) is the (n-1)-th term.

In a geometric sequence, the ratio (r) between two subsequent terms is constant.  

r = a(n)/a(n-1)

The given sequence is: 45,90,180,360, .....

We can check that:

(90 - 45) is not equal to (180 - 90) and to (360 - 180)

So, there is no common difference in the given sequence.

Let us now check the ratio:

90/45 = 180/90 = 360/180 = 2

The ratio between two subsequent terms is constant, that is 2. Therefore, we can conclude that the given sequence is a geometric sequence with a(1) = 45 and r = 2.

In a geometric sequence, the next term is obtained by multiplying the current term by its ratio.

Hence, the next two terms are calculated as:

360 x 2 = 720

720 x 2 = 1440

It should be noted that the automatic feature then raised the submarine 50 3/5 feet per minute.

Therefore, the time needed to reach the depth will be:

Answer:

We can use the point-slope form of the equation of a line to find the equation that passes through the points (3, 5) and (6, 7).

The point-slope form of a line is:

y - y1 = m(x - x1)

where (x1, y1) is one of the points on the line and m is the slope of the line.

First, we need to find the slope of the line using the two given points. The slope formula is:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the two points.

Plugging in the values we know, we get:

m = (7 - 5) / (6 - 3) = 2 / 3

So the slope of the line is 2/3.

Now we can use one of the given points and the slope to write the equation of the line in point-slope form. We'll use the first point, (3, 5).

y - 5 = (2/3)(x - 3)

This is the equation of the line in point-slope form.

If we want to write it in slope-intercept form (y = mx + b), we can simplify:

y - 5 = (2/3)x - 2

y = (2/3)x + 3

So the equation of the line that passes through the points (3, 5) and (6, 7) is y = (2/3)x + 3.

2) Now, add eight to both sides. Your equation now looks like this:

-8 + 8 - 3k = 22 + 8

3) Simplify.

-3k = 30
