Find the perimeter and area of each figure.

There are 55 values in the range 0 to 55

The minimum is given as:

Minimum = 0

The maximum is given as:

Maximum = 55

The range is calculated using:

Range = Maximum - Minimum

So, we have:

Range = 55 - 0

Evaluate

Range = 55

Hence, there are 55 values in the range 0 to 55

The mean of this test will be 57.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

The mean can be used to get an overall idea, or picture, of the data set.

Let Mean be 'm'

and standard deviation= [tex]\sigma[/tex]

So, m-2[tex]\sigma[/tex]=49

and, m + [tex]\sigma[/tex]=61

Solving the above two equation we get

[tex]\sigma =4[/tex]

Now, m= 61-[tex]\sigma[/tex]

           = 61-4

           = 57

So , the mean of this test will be =57

Answer:

AI=3.25 IH= 4.2

Step-by-step explanation

The distance between C and D is 1.3 inches, the distance between E and F is 0.75 inches and the distance between G and H is 1.2 inches. This is true because the model says so. If you look closely together, this is equal to the distance between AI which is the length of AI. The answer would be 1.2+1.3+0.75=3.25. To find the length of side IH you do the same strategy, the distance between sides D and E is 4.8 inches, at the bottom is 9 inches of distance between side I and side F. 9-4.8 inches is equal to 4.2 inches. Therefore, the length of side AI is 3.25 inches and the length of side IH is 4.2 inches. If I am wrong please tell me for feedback, I also hoped that this has helped you in your learning :)

Answer: 4

Step-by-step explanation:

      First, we will find the length of sides TU and T'U' to compare. Then, we will find the scale factor. Since the shape gets bigger and not smaller, we will have a whole number - not a fraction.

TU = 3 units

T'U' = 12 units

12 / 3 = 4

Answer:

2n + 2

Step-by-step explanation:

If the directions for this problem say to "Simplify" then what you will do is to combine like terms. This is an expression because there is no equal sign. If it had an equal sign (and more information) it could be solved.

Since it only an expression we simplify:

-n + (-3) + 3n + 5

= -n + 3n + (-3) + 5

= 2n + 2

Answer:

I believe that it is, 2n + 2.

Step-by-step explanation:

You add all the common factors ( sorry if its a wrong vocab word ) -

( {-3} + 5 ) and ( 3n + { -n } )

-3 + 5 would also be 5 - 3 = 2

3n + -n would be 3n - n = 2n so it would be,

2n + 2 or 2 + 2n.

Answer:

MN is correct

Step-by-step explanation:

A segment bisector passes through the midpoint of the segment and divides it in half. Since MN does both of these, it is the segment bisector.

Answer:

MN: 32

Step-by-step explanation:

We have been given the two lengths as x and y So, the value of x would be equal to root 80.

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]

where  is a common factor (not 1)

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly canceled from both the numerator and the denominator.

Thus, a = px, b = qx

we have been given the two lengths as x and y.

From the figure, we know that

11: y = y: 5

Express in fraction

11/y = y / 5

y^2 = 5(11)

y ^2 = 55

So, y = √55

From Pythagoras theorem;

[tex]x^{2} =5^{2} +y^{2} \\\\x^{2} =5^{2} +55 \\\\x^{2} =25 + 55\\\\x^{2} =80\\\\x = \sqrt{80}[/tex]

The result for the expression (cos 3x)(cos x) − (sin 3x)(sin x) is cos 4x.

Equations involving trigonometric functions that hold true for all possible values of the variables are known as trigonometric identities.

In terms of functions of A and B, angle addition formulae express trigonometric functions of sums of angles A[tex]\frac{+}{_}[/tex]B.

cos (A+B) = cosA.cosB + sinA.sinB

The give equation is as follows,

(cos 3x)(cos x) − (sin 3x)(sin x)

Applying the sum formula,

= (cos 3x)(cos x) − (sin 3x)(sin x)

= cos(3x + x)

= cos 4x

Answer:

  4568 ft³

Step-by-step explanation:

You want the volume of the figure made from two rectangular prisms.

The volume of the whole is the sum of the volumes of its parts. The volume of a rectangular prism is the product of its dimensions.

The horizontal prism is 7 ft high, 8 ft wide, and 45 ft long.

The vertical prism has a square base 8 ft on a side, and is 32 ft long.

The total volume is ...

  V = horizontal volume + vertical volume

  V = (7 ft)(8 ft)(45 ft) + (8 ft)²(32 ft) = 4568 ft³

The volume of the figure is 4568 ft³.

<95141404393>

The total volume of the figure is 4,568 ft³

We can view this as two different rectangular prisms, remember that the volume of a rectangular prism is equal to the product between its dimensions.

For the one that is laid down, the volume is:

V = 7 ft*8 ft*45 ft

V = 2,520 ft³

For the other prism, the volume will be:

V' = 8ft*8ft*32ft = 2,048 ft³

Adding the two volumes we will get:

volume = 2,520 ft³ +  2,048 ft³ = 4,568 ft³

That is the total volume of the figure in cubic feet.

Answer:

on the hypotenuse

Step-by-step explanation:

Circumcenter lies at the midpoint of the hypotenuse side of a right-angled triangle.

The coordinates of point A when it is rotated about 180 degrees will be (7,-4).

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

Given that:-

As it is turned 180 degrees from its initial position ( -7,4) just opposite side of the origin so the new coordinates of the point will be (4,-7).

Therefore the coordinates of point A when it is rotated about 180 degrees will be (7,-4).
