The value of both x and y are 6 degrees in the given figure of arrangement.

What is angle bisector ?

angle bisector is the line which divides the given angle into two equal parts.

a) Here, the line RQ is the angle bisector of angle ∠WRV that is RQ line divides the angle ∠WRV into two equal parts and it is given that :

angle ∠WRQ is 48 degrees

and, angle ∠QRV is 7y+6

Therefore, ∠WRQ = ∠QRV

7y+6 = 48

7y = 48-6

7y = 42

y = 6 degrees

b) It is given that CR is perpendicular to PR that is angle ∠CRP will make 90 degrees and it is given as :

∠CRP = 13x + 12 degrees

90 = 13x + 12

13x = 78

x = 6 degrees

Therefore, the value of both x and y are 6 degrees.

A rectangle as the only parallelogram that can be inscribed in a circle.

A rhombus's opposite angles are congruent. If a rhombus has an angle, it has one pair of opposite angles that are and another pair of opposite angles that are. Because opposite angles are not supplementary, this rhombus cannot be encircled.

Because not all quadrilaterals can be inscribed in circles, they are not all cyclic quadrilaterals. If and only if the opposite angles of a quadrilateral are supplementary, it is cyclic.

A rectangle is the only parallelogram that can be inscribed in a circle. The important point is that the radius of the circle is R, because every rectangle can be inscribed in a (unique circle). (I believe.) One of the properties of a rectangle is that the diagonals bisect in the 'center,' which is also the circumscribing circle's center.

The graph of f(x) is shifted 5 units to the left to create g(x).

A parent function is an equation in the simplest form of a family of functions. A family of functions is a collection of functions that represent similar characteristics and/or transformations of its parent function. A parent function can be represented with different degree values such as degrees 1, 2, or 3.

The most basic parent function is called a constant function.

Types of Parent Functions

There are multiple forms of parent functions. Some types of parent functions are:

Constant function: A horizontal line that intersects the y-axis.

Square root function: The inverse function of a quadratic function following the form f(x)= [tex]\sqrt{x}[/tex]

Cube root function: The inverse function of a cubic function in the form f(x)= 3     [tex]\sqrt{x}[/tex]

A parent function is the simplest form that a function can be. Its basic shape is not in any way altered.

For instance, when you see a u-shaped graph that is inverted and vertically stretched, you should still recognize that it is a parabola which has undergone different transformations

A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

The scores on the statistics test was normally distributed with a mean of 86, a standard deviation of 5, and Jose scored a 93 on his test.

We need to find the percentage of the class scored less than he did

z=(x-mean)/ S.D

The equation for the vertical translation of y=f(x).2/3 unit down is y=f(x)-2/3.

Using equations of the form y=f(x), you may be able to modify the graph in various ways. For example, you can move the chart up, down, left, or right, flip it around the x or y-axis, or stretch or shrink it vertically or horizontally. Understanding these transformations makes it easy to graph different functions. Start with a "basic model" and apply a series of modifications to change it to the desired function.

A point on the graph of y=f(x) has the shape (x,f(x)).

The points on the graph of y=f(x)-2/3 are of the form (x,f(x)-2/3).

So, the graph for y=f(x) -2/3 is the same as the graph for y=f(x) shifted down by 2/3 units.

The new equation is:

y=f(x)-2/3

Answer:

Step-by-step explanation:

you know the area of a rectangle or square is length x width, we do the same here.

so we have a length of (x+5) and because its a square we do (x+5)(x+5) which is

and we know the area of the square is 30 so we make the expression above equal to 30 and take 25 away from both sides to get the wanted equation

A) The type of variation between pitch and wavelength is an inverse variation. b) the pitch when the wavelength is 5 feet would be 132 hertz.

we know that the Inverse Variation is a relationship between two variables in which the product is a constant.

Let x be a pitch of a musical instrument

y be the wavelength

x*y=k

We need to find the value of k for x=220 hertz   and y=3 ft

Then x*y=k

220*3=k

k=660

And for x=165 hertz ,  y=4 ft

x*y=k

165*4=660

k=660

A) Therefore, the type of variation between pitch and wavelength is an inverse variation.

B) the pitch when the wavelength is 5 feet;

x=?

y=5 ft

k=660

x*y=k

Then solve for x

x=k/y

x=660/5

According to the census data, the population of China is more than the population of US by a factor 4.2

Given data

population of China = 1.3x10^9

population of US = 308,745,538

population of china = 1.3x10^9. can be rewritten as = 1,300,000,000

comparing the both figures representing population. we divide the population of China by the population of US

let the number of times the population of china is greater than population of US be x, such that

308,745,538 * x = 1,300,000,000

308,745,538x = 1,300,000,000

x = 1,300,000,000 / 308,745,538

x = 4.2106

x ≅ 4.2

We therefore say that the population of china is more than the population of US by a factor 4.2

The likelihood that Zoe would then strike out in her further at bat this season is calculated.

The various findings or components in a pie chart are depicted by the sectors of a circle, and the entire circle symbolizes the total of the value of each of the components. Obviously, the overall angle of 360° at the central point of the circle is divided by the component values.

Now, for the stated question; It is mentioned that-

Step 1: Last season, Zoe struck out in 10% of her at-bats.

Thus, the probability that the Zoe struck out in her at-bats is 10%.

Then, the probability that the Zoe does not struck out in her at-bats is 90%.

Step 2: The simulation will have 40 trials.

Step 3: We can employ a spinner split into two sectors, one that included 10% of the spinner's area while the other 90%. Determine the central angle of the each sector.

Zoe got thrown out =10% of 360° = 36° Sector yellow

Zoe does not strike out (90 percent of 360° = 324°).

Consider the blue sector in the graph.

Step 4: A trial consists of one spin of the spinner and one strike on the bat by Zoe.

A successful trial means Zoe did not strike out, while a failed trial implies Zoe did strike out. The simulation will include 40 trials.

Answer:

Length is 26.25 and width is 21.25

Step-by-step explanation:

the length is gonna be the width but plus 15, so W+15, and we know that there's 2 widths and 2 lengths in a perimeter so were gonna start off our algebraic expression like this:

2(15+W)+2W=115

distribute the 2

30+2W+2W=115

combine like terms

30+4W=115

subtract 30 from both sides

4W=85

divide 4 from both sides

W=21.25

now plug in our width value into W+15 to find length

W+15

21.25+15=L

36.25=L
