What is the transformation of a graph?

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the give M and M'.

If we draw a line of the same corner points of M' and M then it goes from point B.

So it is clear that M is dilated with respect to point B.

Hence "The center of dilation of the figure M' is B".

Answers

Answer:

Revenue is the total amount producers receive after selling a good. Profit is the total amount producers earn after subtracting the production costs.

Step-by-step explanation:

Profit, or net gain, is the amount of money made after subtracting production costs.

Revenue is the total amount of money earned, or gross weight, before anything is subtracted for production costs.

Answer:

The revenue is the total amount producers receive after selling a good. Profit is the total amount producers earn after subtracting the production cost.

Step-by-step explanation:

To answer the question, let us picture that you have a business, and you sell bread.

If you sell bread for $5 per loaf, and you sell 2 loaves, your revenue will be 2 * 5 = $10.

Let's say that in order to bake the bread, you have to rent your neighbor's oven for $0.25 per hour, the flour costs $1 per loaf, and the yeast costs $1 (these are all made-up numbers). If each loaf takes one hour to bake, two loaves will cost 0.5 + 2 + 2 = $4.50 to make. Your profit will then be your revenue minus your cost, or 10 - 4.5 = $5.50.

From this scenario, we can see that the revenue is the total amount producers receive after selling a good. Profit is the total amount producers earn after subtracting the production cost.

We define a bow-tie quadrilateral as a quadrilateral where two sides cross each other. An example of a bow-tie quadrilateral is shown below. Seven distinct points are chosen on a circle. We draw all $\binom{7}{2} = 21$ chords that connect two of these points. Four of these $21$ chords are selected at random. What is the probability that these four chosen chords form a bow-tie quadrilateral?

Answers

Four chosen chords form a bow-tie quadrilateral 2210 .

What is a quadrilateral?A quadrilateral is a polygon having four sides, four angles, and four vertices. The word 'quadrilateral' is derived from the Latin words 'quadri,' which means four, and 'latus', which means side. The above image is an example of a quadrilateral.The bowtie, or crossed rectangle, is a nonconvex semi-uniform quadrilateral with the same vertices as a rectangle but with two of the original sides removed and with the original's diagonals in place instead.

Given,

              We are aware that a quadrilateral requires four vertices (or points on the circle). The cross can always be connected in one of two ways: horizontally or vertically. My understanding of combinations is inadequate, but we can deduce that picking four points from a possible seven equals 21. Four points can be used to create 21*2 = 42 "bow-tie quadrilaterals" on the circle by multiplying the two methods to join those lines (again, horizontally and vertically). Since there are 2210 possible combinations of four chords out of a possible 21 chords, the probability is 42/2210, and we just need to reduce that fraction.

Therefore, Four chosen chords form a bow-tie quadrilateral 2210 .

The probability that the four chosen chords form a bow-tie quadrilateral is: 60%.

First, let's calculate the total number of ways to choose four chords out of the 21 available chords.

= 21!/ 4! (21-4)!

= 21! / 4! 17!

= 5985

The number of ways to choose two intersecting chords can be represented as [tex]\binom{7}{2}.[/tex]

= 7! / (7-2)!

= 7!/ 5! 2!

= 7 x 6/ 2

= 21

However, we also need to account for the fact that we are choosing four chords in total.

So we need to choose two more chords from the remaining 19 chords.

C(19, 2)= 19!/{2!(19-2)!

= 19! / 2! 17!

= 19 x 18 /2

= 171

Now,  the number of ways to choose four chords that form a bow-tie quadrilateral

= 21x 17

= 3591

Therefore, the probability that the four chosen chords form a bow-tie quadrilateral is:

= [tex]$\frac{\text{Number of ways to choose four chords forming a bow-tie quadrilateral}}{\text{Total number of ways to choose four chords}}[/tex]

= 3591/5985

= 0.600

So, the probability is 0.600, or 60%.

List below are the speeds (mi/h) measured from southbound traffic on I-280 near Cupertino, CA. Use the sample data to construct a 99% confidence interval estimate of the population standard deviation: speeds 62, 58, 58, 56, 60, 53, 58

Answers

Answer:

The 99% confidence interval of the population standard deviation is 1.7047 < σ < 7.485

Step-by-step explanation:

Confidence interval of standard deviation is given as follows;

[tex]\sqrt{\dfrac{\left (n-1 \right )s^{2}}{\chi _{1-\alpha /2}^{}}}< \sigma < \sqrt{\dfrac{\left (n-1 \right )s^{2}}{\chi _{\alpha /2}^{}}}[/tex]

s = [tex]\sqrt{\dfrac{\Sigma (x - \bar x)^2}{n - 1} }[/tex]

Where:

[tex]\bar x[/tex] = Sample mean

s = Sample standard deviation

n = Sample size = 7

χ = Chi squared value at the given confidence level

[tex]\bar x[/tex] = ∑x/n = (62 + 58 + 58 + 56 + 60 +53 + 58)/7 = 57.857

The sample standard deviation s = [tex]\sqrt{\dfrac{\Sigma (x - \bar x)^2}{n - 1} }[/tex] = 2.854

The test statistic, derived through computation, = ±3.707

Which gives;

[tex]C. I. = 57.857 \pm 3.707 \times \dfrac{2.854}{\sqrt{7} }[/tex]

[tex]\sqrt{\dfrac{\left (7-1 \right )2.854^{2}}{16.812}^{}}}< \sigma < \sqrt{\dfrac{\left (7-1 \right )2.854^{2}}{0.872}}[/tex]

1.7047 < σ < 7.485

The 99% confidence interval of the population standard deviation = 1.7047 < σ < 7.485.

Which statement is true about the given function?
fx) > 0 over the interval (-0,3).
f(x) > 0 over the interval (-:-).
f(x) <0 over the interval (-0,3).
f(x) <0 over the interval (- : -).

Answers

Answer:

Option C.

Step-by-step explanation:

If the graph of a function f(x) lies above the x-axis, then f(x) > 0.

If the graph of a function f(x) lies below the x-axis, then f(x) < 0.

From the given graph it is clear that the graph of f(x) intersect the x-axis at x=3.

Before x=3 the graph lies below the x-axis. So,

[tex]f(x) < 0[/tex] over the interval [tex](-\infty,3)[/tex].

After x=3 the graph lies above the x-axis. So,

[tex]f(x) > 0[/tex] over the interval [tex](3,\infty)[/tex].

Therefore, the correct option is C.

x can only equal 7.4.
O x can equal -3.2 or -7.4.
O x can equal -3.2 or 7.4.

Answers

Answer:  x can equal -3.2 or -7.4.

Step-by-step explanation:

The correct expression is:

2|x+5.3|=4.2

So, we have an absolute value equation, where it can be positive or negative:

Positive

2 (x+5.3)=4.2

2x+10.6 =4.2

2x=4.2-10.6

2x = -6.4

x= -6.4/2

x = -3.2

Negative

2[-(x+5.3)]=4.2

-2x-10.6 =4.2

-2x= 4.2+10.6

-2x= 14.8

x= 14.8/-2

x= -7.4

x can equal -3.2 or -7.4.

Answers

Answer:

The answer is given below

Step-by-step explanation:

The equation of a quadratic function is given by:

Ax² + Bx + C where A, B and C are the coefficients of the quadratic equation. If the coefficient of x² (i.e A) is a negative value then the graph opens down, the value of C determines the y intercept.

The equation of a parabola with  y-intercept greater than 3 and opens down can be given as -2x² -6x + 4. Since the coefficient of x² is negative it opens down and C = 4, it has a y intercept of 4 > 3

Let us assume a vertical stretch of 2, the new equation becomes:

2(-2x² -6x + 4)

-4x² - 12x + 8

To solve:

-4x² - 12x + 8 = 0

A = -4, B = -12 and C = 8

Using the quadratic formula:

[tex]x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}\\ x=\frac{-(-12) \pm \sqrt{(-12)^2-4(-4)(8)} }{2(-4)}=\frac{12 \pm 16.49}{-8} \\x= -3.6 \ or \ x=0.6[/tex]

About ? percent of these confidence intervals will contain the true population mean number of missed class days and about ? percent will not contain the true population mean number of missed class days.

Answers

Step-by-step explanation:

a. When the sample size is below 30 or the population standard deviation is not known, use a t distribution rather than a normal distribution.

b. The confidence interval is:

CI = x ± CV × SE

where x is the sample mean,

CV is the critical value (in this case, t).

and SE is the standard error (the sample standard deviation).

For the data given, the mean is x = 4.545, and the standard deviation is SE = 3.503.

There are 11−1 = 10 degrees of freedom, and the confidence level is 98%.  For a t-table, the critical value is CV = 2.764.

So the confidence interval is:

CI = 4.545 ± 2.764 × 3.503

CI = (-5.1, 14.2)

c.  The confidence level is 98%, so 98% of these confidence intervals will contain the true population mean, and 2% will not.

mean: 3 minutes and 48 seconds = 3*60 + 48 = 228 s standard deviation, sd: 19 svalue of interest, x: 4 minutes = 4*60 = 240 s

Z-score is calculated as follows:

z = (x - mean)/sd

z = (240 - 228)/19

z = 0.63

We want to find the next probability P(Z>0.63), which is equivalent to 1 - P(Z≤0.63)

From table, 1 - P(Z≤0.63) = 1 - 0.7357 = 0.2643 or 0.2643*100 = 26.43%

(b) We want to find z1 at which P(Z≤z1) = 0.2. From the second table, z1 is between -2.05 and -2.06.

z = (x - mean)/sd

-2.055 = (x - 228)/19
