Answer 1

[tex]\bold{\huge{\underline{ Solution }}}[/tex]

Given :-

We have given some information in the above table

To Find :-

We have to find the mean, median and mode of the given data.

Let's Begin :-

For completion of table you should know the basics formulas :-

For calculating x( mid point)

[tex]\sf{=}{\sf{\dfrac{Sum \:of\: class \:interval }{ 2}}}[/tex]

That is,

[tex]\sf{=}{\sf{\dfrac{ = 18 + 25}{2}}}[/tex]

[tex]\sf{=}{\sf{\dfrac{ = 43}{2}}}[/tex]

[tex]\sf{= 21.5 }[/tex]

[ For more calculation ,Please refer the attachment ]

For calculating fx Multiply frequency and midpoint

[tex]\sf{ fx = frequency {\times} midpoint }[/tex]

[tex]\sf{ fx = 8 {\times} 21.5 }[/tex]

[tex]\sf{ fx = 172 }[/tex]

[ For more calculation please refer the attachment ]

Now,

We have to calculate mean, median and mode of the given data

For mean

We know that the,

Mean = Sum of all observation / no. of observation

That is

[tex]\sf{ Mean = }{\sf{\dfrac{ {\sigma}fx}{{\sigma}x}}}[/tex]

Subsitute the required values,

[tex]\sf{ Mean = }{\sf{\dfrac{ 1811 }{ 187.5}}}[/tex]

[tex]\sf{ Mean = 9.65}[/tex]

Hence, The mean of the given data is 9.65

For Median

We know that, For odd numbers

[tex]\sf{ Median = l + }{\sf{\dfrac{ (n/2 - c)}{ f}}}{\sf{ h }}[/tex]

Here,

[tex]\sf{ n = }{\sf{\dfrac{ 50 + 1}{ 2}}}[/tex]

[tex]\sf{ n = }{\sf{\dfrac{ 50 }{ 2}}}[/tex]

[tex]\sf{ n = 25 }[/tex]

Lower limit = 34c = 20f = 14h = 41 - 34 = 7

Subsitute the required values in the above formula :-

[tex]\sf{ Median = 34 + }{\sf{\dfrac{ (25-20)}{ 14}}}{\sf{ 7 }}[/tex]

[tex]\sf{ = 34 + }{\sf{\dfrac{ 5}{ 14}}}{\sf{ {\times}7 }}[/tex]

[tex]\sf{ = 34 + }{\sf{\dfrac{ 35}{ 14}}}[/tex]

[tex]\sf{ = 34 + 2.5}[/tex]

[tex]\sf{ = 36.5 }[/tex]

Hence, The median of the given data is 36.5 .

For Mode

We know that,

[tex]\sf{ M= l }{\sf{\dfrac{ (f1 - fo)}{ 2f1 - fo - f2 }}}{\sf{ {\times} h }}[/tex]

lower limit = 34 f1 = 14fo = 12f2 = 12H = 7

Subsitute the required values,

[tex]\sf{ M= 34 }{\sf{\dfrac{ (14 - 12)}{ 2(14)- 12 - 12 }}}{\sf{ {\times} 7 }}[/tex]

[tex]\sf{ M= 34{\times}}{\sf{\dfrac{ 2}{ 28 - 24 }}}{\sf{ {\times} 7 }}[/tex]

[tex]\sf{ M= 34{\times}}{\sf{\dfrac{ 2}{ 4 }}}{\sf{ {\times} 7 }}[/tex]

[tex]\sf{ M= 34{\times}}{\sf{\dfrac{ 1}{ 2 }}}{\sf{ {\times} 7 }}[/tex]

[tex]\sf{ M= 34{\times}}{\sf{\dfrac{ 7}{ 2 }}}[/tex]

[tex]\sf{ M= 34 + 3.5 }[/tex]

[tex]\sf{ M= 37.5 }[/tex]

So,

Mode = 37.5

Hence ,The mode of the given data is 37.5 .

Can someone please please tell me what the general form for (x-6)^2+(y-3)^2=16 is. I would really appreciate the help!

Answers

Answer:

x² + y² - 12x - 6y + 29 = 0

Step-by-step explanation:

Simplifying the equation using (a + b)² = a² + 2ab + b²:

(x - 6)² + (y - 3)² = 16

⇒ [x² - 2(x)(6) + 6²] + [y² - 2(y)(3) + 3²] = 16

⇒ [x² - 12x + 36] + [y² - 6y + 9] = 16

⇒ x² - 12x + 36 + y² - 6y + 9 = 16

General form of a circle = x² + y² + Cx + Dy + E = 0

Before we reorganize the equation in general form, we need to have the R.H.S as 0. For that, we need to subtract 16 both sides.

Subtract 16 both sides:

⇒ x² - 12x + 36 + y² - 6y + 9 = 16

⇒ x² - 12x + 36 + y² - 6y + 9 - 16 = 16 - 16

⇒ x² - 12x + 20 + y² - 6y + 9 = 0

Reorganizing the equation in general form:

x² - 12x + 20 + y² - 6y + 9 = 0

⇒ x² - 12x + 20 + y² - 6y + 9 = 0

⇒ x² + y² - 12x + 20 - 6y + 9 = 0

⇒ x² + y² - 12x + 20 - 6y + 9 = 0

⇒ x² + y² - 12x - 6y + 20 + 9 = 0

x² + y² - 12x - 6y + 29 = 0

Thus, the equation in general form is x² + y² - 12x - 6y + 29 = 0.

y = 3x - 10 and y=2x-5

Answers

Answer:

x=5

y=5

y = 3x - 10 -----------(1)

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

Step-by-step explanation:

put the value of y in 2nd equation

y=2x-5

=3x - 10=2x-5

=3x-2x=-5+10

= x=5,

now put the value of x in 1st equation.

y = 3x - 10

=y=3×5-10

=y=15-10

= y=5.

check

put the value of x and y in 1st equation.

y = 3x - 10

x=5,,y=5

=5=3×5-10

= 5=5

find the missing side of the parallelogram. keep answer in simplest form

Answers

Area of parallelogram is Base×height

10×18=15× x

x= 12

hope it helps

Answer:

x = 12

Step-by-step explanation:

So, area of a parallelogram is base times height.

In this picture, one of the base, height pair is 18 and 10.

18 * 10 = 180

The other base, height pair is 15 and x.

So, 15 and x should equal to 18 * 10.

Then, 15x = 180.

Divide both sides by 15, and you get 15x/15 = x and 180/15 = 12.

So, x = 12

The graph below represents data that was collected by students on the number of
social media posts they made the previous day.


What was the mean number of posts made?

Answers

Answer:

4

Step-by-step explanation:

To calculate the mean or average, add all the data point up and whatever the amount of data point there are is supposed to be divided by the sum of the data points. So in this case, 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. This is the sum of the data points. Now we have to divide by the amount of data points which is 7 (0 obviously has no value whatsoever).  28 divided by 7 is 4. The average/mean of the number of post made is therefore 4.

Write a slope intercept form that contains the points(3,4) and (-6,2)

Answers

Answer:

[tex]y=0x+2[/tex]

Step-by-step explanation:

Given the following question:

Point A = (3, 2) = (x1, y1)
Point B = (-6, 2) = (x2, y2)

To write the following points in slope intercept form we first need to calculate the slope by using the formula for slope or rise over run.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{2-2}{-6-3} =\frac{0}{-9}[/tex]
[tex]0\div-9=0[/tex]
[tex]m=0[/tex]

Now that we have to slope, we can now write the points in slope intercept form by using the formula y = mx + b and solve for b.

[tex]y=mx+b[/tex]
[tex]y=2[/tex]
[tex]m=0[/tex]
[tex]x=3[/tex]
[tex]2=0(3)+b[/tex]
[tex]0\times3=0[/tex]
[tex]2=0+b[/tex]
[tex]2+0=2[/tex]
[tex]2=b[/tex]
[tex]b=2[/tex]
[tex]y=0x+2[/tex]

Your answer in slope intercept form is "y = 0x + 2."

Hope this helps.

Answers

Answer:

n = 11°

Step-by-step explanation:

When two straight lines intersect each other, then the pairs of angles so formed without any common arm are called vertically opposite angles.

Vertically opposite angles are equal to each other.

So,

[tex]{\longrightarrow \it\qquad { \ { (6n - 4) {}^{ \circ} = {(5n + 7)}^{ \circ} }}}[/tex]

Removing the brackets,

[tex]{\longrightarrow \it\qquad { \ { 6n - 4{}^{ \circ} = {5n + 7 \: }^{ \circ} }}}[/tex]

[tex]{\longrightarrow \it\qquad { \ { 6n - 5n = { 7 \: }^{ \circ} +4{}^{ \circ} }}}[/tex]

[tex]{\longrightarrow \it\qquad { \pmb{ n = { 11 \: }^{ \circ} }}}[/tex]

Therefore,

The value of n is 11°

We will use the concept of Vertically Opposite angle here, i.e at the point of Intersection of two straight lines, the VOA (Vertically Opposite Angles) are equal

By using this property we will be having ;

[tex]{:\implies \quad \sf (6n-4)^{\circ}=(5n+7)^{\circ}}[/tex]

[tex]{:\implies \quad \sf 6n-5n=7+4}[/tex]

What is Pythagoras theorem?

Pythagoras theorem says that in a right angle triangle the square of hypotenuse side is equal to the sum of square of other two legs of right angle triangle.

A 15-meter by 23-meter garden is divided into two sections. In this rectangle,

Two sidewalks run along the diagonal of the square section and along the diagonal of the smaller rectangular section. The length of the top and bottom sides is 23 meters. The length of the left and right sides is 15 meters.

Here, a vertical line is drawn from the top to bottom side to split the shape into a square and a rectangle. The length of the left side of the square will be 15 long. Thus, the lenght of its diagonal is,

[tex]d_1=15\sqrt{2}\\d_1=21.213\rm\; m[/tex]

The length of the sidewalk in smaller rectangle in the right side of figure is,

[tex]d_2=\sqrt{15^2+8^2}\\d_2=17\rm\; m[/tex]

Sum of the lengths of the two sidewalks using the pythagoras theorem is,

[tex]S=21.2+17\\S=38.2\rm\;m[/tex]

Thus, approximate sum of the lengths of the two sidewalks, shown as dotted lines in the figure of rectangle garden is 38.2 meters.

Using the two given solutions and the general absolute value function we will get:

|x + 9|  = 27

Which absolute value function has that solution set?

The two solutions are:

x = 0 and x = -18.

Remember that the absolute value equation is something like:

|x - a| = b

If we want to have these solutions, then:

|0 - a| = b

|-18 -a| = b

From the first one, we have:

|-a| = b

Replacing that on the second equation we get:

|-18 -a| = |-a|

Notice that if we take a = -9, then we have:

|-18 + 9| = |+9|

|-9| = |+9|

This is true, so a = -9.

Then we find the value of b:

|18 + 9| = b = 27

Then the absolute value equation is:

|x + 9|  = 27
