The histogram is unimodal as it has only one peak point and roughly symmetric because both sides of the histogram when flipped across the axis of symmetry does not overlap completely.

Histogram is a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.

Given is histogram that shows heights of 300 randomly selected high school students.

The shape that best describes the distribution of heights is - Roughly symmetric and unimodal. Unimodal histograms have only one peak in the distribution. It can be seen from the image that the graph has only one peak point. However, if we check the symmetry of this histogram by drawing the axis of symmetry, then both sides will not overlap completely. So it is Roughly symmetric.

Therefore, the histogram is unimodal as it has only one peak point and roughly symmetric because both sides of the histogram when flipped across the axis of symmetry does not overlap completely.

A translation maps one triangle onto the other. Each pair of corresponding sides has the same measure, so they are congruent. △MNO ≅ △QRS by SSS.

What exactly do you mean by congruent?

Use the Distance Formula to find the lengths of.

MN , NO , OM

MN has end points M(4 , 7)  And N( 5, 4 )

MN = [tex]\sqrt{ (x_{2} - x_{1}^{2}+ ( y_{2} - y_{1} )^{2}[/tex]

      = [tex]= \sqrt{(1)^{2} + ( -3)^{2} }[/tex]

       [tex]= \sqrt{ 1 + 9 }[/tex]

         [tex]= \sqrt{10}[/tex]

NO has end points N(5, 4) and O(2, 3).

NO = √( 2 - 5 )² + ( 3- 4 )²

      = √( - 3)²  + ( -1)²

      = √ 9 + 1 = √10

OM has end points O(2, 3) and M(4,7)

OM = √( 4 - 2 )² + ( 7 - 3 )²

      = √ (2)²  + ( 4 )²

       = √20

Similarly, find the lengths of QR, RS , SQ

QR has end points Q(2, 5) and R(3, 2).

QR = √( 3 - 2)² + ( 2 - 5 )²

     = √(1)² + ( -3)²

     = √ 1 + 9

      = √10

RS has end points R(3, 2) and S(0, 1).

RS = √( 0- 3)² + ( 1 - 2 )²

     = √( -3)² + (-1)²

      = √9 + 1 = √10

SQ has end points S(0, 1) and Q(2, 5).

SQ = √ ( 2 - 0 )² + ( 5 - 1 )²

      = √ 4 + 16  = √20

So, MN ≅ QR , NO ≅ RS and OM ≅ SQ

Answer:

x= 8, z= 118

Step-by-step explanation:

To find x, solve the equation with the one unknown x given by supplementary angles definition.

Supplementary angles sum up to 180° there for

8x +54 + 7x +6 = 180, group like terms

8x + 7x = 180 -54-6, combine like terms

15x = 120, divide both sides by 15

x = 8

To find z, solve for z the equation given by vertical angles definition.

Vertical angles are congruent there for

8x +54 = z, substitute x for 8

8·8 +54 = z, multiply then add

z = 118

Based on the definition of supplementary angles, x = 8; z = 118

Based on the definition of supplementary angles we have:

7x + 6 + 8x + 54 = 180

Solve for x

15x + 60 = 180

15x = 180 - 60

15x = 120

x = 120/15

x = 8

z = 8x + 54 (vertical angles)

Plug in the value of x

z = 8(8) + 54

z = 118

Given  statement 'The ₋Law of Sines can be used to find an angle measure when given three side lengths.' is False.

The correct statement is 'The ₋Law of cosines can be used to find an angle measure when given three side lengths.'

We know that an oblique triangle is a triangle which is either acute triangle or obtuse triangle but not a right triangle.

We know that the Law of Sines defines the relationship between the sides and angles of an oblique triangle.  

And to use the Law of Sines we must know either two angles and one side of the triangle or two sides and one of the opposite angle to them (SSA).

But, the Law of Cosines is used to find the remaining parts of an oblique triangle.

This means, in case of the  Law of Cosines when either the two sides and the angle included is given or the lengths of the three sides are given then we find the remaining angle measure.

Therefore, given statement 'The ₋Law of Sines can be used to find an angle measure when given three side lengths.' is False.

The equation in slope-intercept form for the line that passes through (-0,7), parallel to y = 4x-19 is y = 4x + 7.

The slope intercept form of a line is:-

y = mx + b

Where:-

m represents the slope of a line

b represents the y-intercept of a line

x and y represent the ordered pairs (x,y) throughout a line

We are given the line y = 4x-19 is parallel to the line whose equation we have to find.

Hence,

slope of the line = 4 = slope of the given line

Also, (0,7) passes through the line,

Hence,

7 = 4*(0) + b

7 = 0 + b

b = 7

Hence, the equation of the line in slope intercept form is y = 4x + 7.

The triangle having vertices X(1,2), Y(4,6), Z(6,6) is obtuse.

According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:

XY = [tex]\sqrt{(4-1)^{2} + (6 - 2)^{2} }[/tex]

∴ XY = 5

YZ = [tex]\sqrt{(6 - 4)^{2} + (6 - 6)^{2} }[/tex]

∴YZ = 2

ZX = [tex]\sqrt{(6 - 1)^{2} + (6 - 2)^{2} }[/tex]

∴ ZX = 6.4

∴The longest side is ZX = 6.4

Hence, a = XY, b = YZ and c = ZX;

Consider          [tex]a^{2} + b^{2}[/tex]:

= [tex]XY^{2}[/tex] + [tex]YZ^{2}[/tex]

= [tex]5^{2} + 2^{2}[/tex]

= 29.

Now consider [tex]c^{2}[/tex]:

= [tex]6.4^{2}[/tex]

= 40.96.

Thus, [tex]c^{2} > a^{2} + b^{2}[/tex]

Hence, the triangle is obtuse.

By elimination, the solution of the system of equations, 2x - 3y = 4 and 2x - 5y = -6, is (19/2 , 5).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Use the elimination method since subtracting the two equations will eliminate the variable x.

2x - 3y = 4     (equation 1)

2x - 5y = -6    (equation 2)

0x + 2y = 10

y = 5

Substitute the value of y to any of the two equation and solve for x.

2x - 3y = 4     (equation 1)

2x - 3(5) = 4

2x = 4 + 15

2x = 19

x = 19/2

Hence, the solution of the system of equations is (19/2 , 5).
