Answer:

The value of bc is 5.9 units.

Step-by-step explanation:

Given information: b is between a and c, ac=15.8 and ab=9.9.

We need to find the measure of bc.

Since b is between a and c, therefore the segment ac is the sum of two segments ab and bc.

[tex]ac=ab+bc[/tex]

Substitute ac=15.8 and ab=9.9 in the above equation.

[tex]15.8=9.9+bc[/tex]

Subtract 9.9 from both sides.

[tex]15.8-9.9=9.9+bc-9.9[/tex]

[tex]5.9=bc[/tex]

Therefore the value of bc is 5.9 units.

If assumption of Collinearity is not for granted, then the length of Segment BC is defined by [tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex], for [tex]\beta \in [0^{\circ}, 180^{\circ}][/tex].

Reminder - Given that statement seems to be incomplete, we assume that we are talking about Line Segments and that Segments AC and BC may be Collinear.

By Geometry and, being more specific, by definition of Triangles, if we assume that all segment are not necessarily Collinear, then a Triangle may exist and can be modelled by the Law of Cosine:

[tex]BC = \sqrt{AC^{2}+AB^{2}-2\cdot AC\cdot AB\cdot \cos \beta}[/tex] (2)

Where [tex]\beta[/tex] is the angle at point B, in sexagesimal degrees and is between 0° and 180°.

If we know that [tex]AC = 15.8[/tex] and [tex]AB = 9.9[/tex], then the expression for the length of BC is:

[tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex]

If assumption of Collinearity is not for granted, then the length of Segment BC is defined by [tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex], for [tex]\beta \in [0^{\circ}, 180^{\circ}][/tex].

The probability that 3 randomly selected people all have the same birthday is 1 in 48,627,125.

In order to find the probability that 3 randomly selected people all have the same birthday, we need to consider the total number of possible outcomes and the number of favorable outcomes. There are 365 days in a year (excluding leap years) and each person's birthday is independent of the others. Therefore, the probability of each person having the same birthday as the previous person is 1/365. To calculate the probability that all 3 people have the same birthday, we multiply the probabilities together:

P(3 people have the same birthday) = (1/365) * (1/365) * (1/365) = 1/48,627,125

Thus, the probability that 3 randomly selected people all have the same birthday is approximately 0.0000000206, rounded to eight decimal places.

Answer:

Step-by-step explanation:

Remember that if two figures have corresponding angles congruent, but proportional sides, then those figures are similar.

However, if those figures have corresponding angles and sides congruent, then they are congruent.

Therefore, to determine if two polygons are congruent, that is, in size and shape, we need to prove that their corresponsing sides are all congruents, that way, we'll be able to demonstrate their absolute congruence.

The value of the function f(x)= 1/x²-3 when x is 3, denoted as f(3), is -8/9.

To solve for f(3) in the function "f(x)= 1/x²-3", you should substitute x = 3 into the function. By doing so, we have:

f(3) = 1/(3²) - 3 = 1/9 - 3 = -8/9

Therefore, f(3) for this function is -8/9.

The first thing to do is to find the roots.

The sum of the roots, x1 + x2 = -b / a

x1 + x2 = 3 / 2

The product of the roots, x1 * x2 = c / a

x1 * x2 = 5 / 2

The AM means arithmetic mean and is calculated using the formula:

AM = (x1 + x2) / 2

AM = (3 / 2) / 2

AM = 3 / 4 = y1

The HM means harmonic mean and is calculated using the formula:

2 / HM = 1 / x1 + 1 / x2

or

2 / HM = (x1 + x2) / x1 * x2

Rewriting in terms of HM alone on the left side:

HM = 2 x1*x2 / (x1 + x2)

HM = 2 (5 / 2) / (3 / 2)

HM = 10 / 3 = y2

Creating an equation from y1 and y2:

(y – ¾) (y – 10/3) = 0

y^2 – 10/3 y – ¾ y + 30/12 = 0

y^2 - 49/12 y + 30/12 = 0       (ANSWER)

or

y^2 – 4.083y + 2.5 = 0

The domain for n in the arithmetic sequence is all integers where n ≥ 1.

The domain for n in the arithmetic sequence is all integers where n ≥ 1. In this sequence, the value of n represents the position of the term in the sequence. Since the first term of the sequence is represented by n=1, n can't be less than 1 because there is no zeroth term in the sequence. Therefore, the domain for n is all integers where n ≥ 1.

So, the problem is asking how many more bears than cougars were in the given region. From the table, we know that there where 790 cougar when the study started.

Now, we have to calculate the initial condition of the function, because it's modelling bear population. Initial condition means when the study started, which is when [tex]x=0[/tex].

So, we have:

[tex]f(0)=830(0.8)^{0}=830(1)=830[/tex]

So, there were 830 bears when the study started.

If we compare, we find that there were 40 more bears than cougars when the study started, because 830-790 = 40.

Solution: The average rate of change of [tex]\frac{-14}{3}[/tex] represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.

Explanation:

The rate of change shows the change in first variable with respect to change in second variable.

If the rate of chang is given by [tex]\frac{-14}{3}[/tex] it means second variable is decrease by 14 if the first variable increase by 3.

In the context of water slide it shows that the vertical height of slide is decreased by 14 units as we cover the distance of 3 units.

If we cover the distance from x = 0 to x = 15, it means we cover the distance of 15 units.

Let the vertical height of the slide covered from x = 0 to x =15 be y.

It means when distance increased by 15 units the height of slide decreased by y units.

So rate of change = [tex]\frac{-y}{15}[/tex].

It is given that the rate of change is [tex]\frac{-14}{3}[/tex].

Equate both equations.

[tex]\frac{-y}{15}=\frac{-14}{3}[/tex]

[tex]y=15(\frac{14}{3} )[/tex]

[tex]y=5(14)[/tex]

[tex]y=70[/tex]

Therefore, the average rate of change of [tex]\frac{-14}{3}[/tex] represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.

What this mean in terms of the waterslide, from x = 0 to x = 15 is:

This refers to how fast or slow a thing is required before it changes form from one form to another.

With this in mind, we can see that with the water slide, there exists the decrease of the vertical height by 14 units over a distance of 3 units.

Therefore, the rate of change is -y/15

If quadrilateral WXYZ is a parallelogram, the opposite sides will be equal, in length from which the value of x will satisfy the two equations.

Response:

Properties of a parallelogram

The length of the opposite sides of a parallelogram are equal, which gives;

2·x - 5 = x + 2

2·x - x = 2 + 5

Similarly, we have;

x + 8 = 15

x = 15 - 8 = 7

The lengths of the opposite sides are therefore;

2·x - 5 = 2 × 7 - 5 = 9 and x + 8 = 15
