Fill In The Frequency Distribution Below

Answers

Answer 1

The frequency for the given distribution of the class interval 1.00 - 1.09 is 3, which are 1.07, 1.05 and 1.07.

What is frequency?

The frequency of a repeating event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to emphasise differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is expressed.

The period is the reciprocal of the frequency because it is the length of time for one cycle in a repeating event. For instance, the period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), is equal to 0.5 seconds (60 seconds divided by 120 beats).

4) How many solutions does the system of linearequations have?2x + 3y = 6-8x - 12y = -20image

Answers

Answer

Explanation

To know how many solutions this system of linear equations have, we willl need to solve it.

2x + 3y = 6

-8x - 12y = -20

Making x the subject of formula in the first equation

2x + 3y = 6

2x = -3y + 6

Divide through by 2

(2x/2) = (-3y/2) + (6/2)

x = (-3y/2) + 3

Substituting this for x in the second equation

-8x - 12y = -20

x = (-3y/2) + 3

Answers

the given UPC bar code digit is

2- 91273 - 05213 - d

for determining d we will follow the rule

first, we sum up all the odd place numbers

like

2 + 1 + 7 + 0 +2 + 3 = 15

then multiply with 3

15 * 3 = 45

then

we sum up all the even place numbers,

9 + 2 + 9 +5 + 1 = 26

now we will add these two results

26 + 45 = 71

now we can see that 71 is 9 less than the next multiple of 10 that is 80 in this case'

80 - 71 = 9

so the answer is

Given:

The difference between two numbers is 22.

The sum of twice the smaller number and 3 times the greater number is 246.

Required:

To find the two numbers.

Explanation:

Let the two numbers be x and y.

Let y be the smaller number.

The difference between two numbers is 22.

[tex]x-y=22[/tex]

The sum of twice the smaller number and 3 times the greater number is 246.

[tex]2y+3x=246[/tex]

Now

[tex]\begin{gathered} 2y+3(22+y)=246 \\ 2y+66+3y=246 \\ 5y=246-66 \\ 5y=180 \\ y=\frac{180}{5} \\ y=36 \end{gathered}[/tex]

If l is parallel m and r parallel s explain how you know Angele 1 and Angle 6 are supplementary

Answers

Angle 4 and angle 6 are supplementary to each other.

Given : the two line r and s are parallel to each other and there are two transversals

And thus angle 6 and angle 4 are equal because angles corresponding angles are equal. This is because of a theorem which states that angles on the same side of the two parallel lines are equal .

And this further implies that the angle adjacent to angle 4 and angle form will form an angle whose sum would be equal to 180 degree. That is they will form a supplementary angle .

And this angle and angle 1 are equal because these two angles are corresponding angles and as mentioned above because of that theorem they are equal.

Thus from these two above mentioned arguments it is clear that angle 4 and angle 6 are supplementary angles .

14. ∠FGB and ∠CHE are  alternate exterior angles.

15. ∠CHG and ∠DHE are vertically opposite angles.

How to find angles?

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles, linear angles etc.

The parallel lines are line AB and CD.

The transversal line is FE.

Therefore,

∠AGH is congruent to ∠DHG because they are alternate interior angles.

Alternate interior angles are congruent.

Distribute the parentheses:

[tex]\implies 12x^2+21x+24+6=22x+33+11[/tex]

[tex]\implies 12x^2+21x+30=22x+44[/tex]

Subtract 22x from both sides:

[tex]\implies 12x^2+21x+30-22x=22x+44-22x[/tex]

[tex]\implies 12x^2-x+30=44[/tex]

Subtract 44 from both sides:

Fill in the boxes with numbers and operations to reflect the equation of the circle after the transformations

Answers

Given the equation of the circle:

[tex]x^2+4x+y^2-12y=-24[/tex]

We will complete the squares for x and y to write the equation of the circle as:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where (h,k) is the coordinates of the circle and r is the radius of the circle

so, the equation will be:

[tex]\begin{gathered} (x^2+4x+4)+(y^2-12y+36)=-24+4+36 \\ \\ (x+2)^2+(y-6)^2=16 \\ \\ (x+2)^2+(y-6)^2=4^2 \end{gathered}[/tex]

So, the radius of the circle = 4

And the center of the circle = ( -2, 6 )

Now, we will make the transformation for the circle:

Shift 1 unit up, the center will be = ( -2, 7 )

shift 2 units right, the center will be = ( 0, 7 )

Reflection across the x-axis, the center will be = ( 0, -7)

So, the equation of the circle after transformation will be:

So, the answer will be:

angle ABC is a circumscribed about point H with points of tangency D,E, F what is the perimeter of a b and c? but i know AB =7 and ac+ad+dc=6+4=10 but i dont know BC and on

Answers

Answer

Perimeter = 22 units

Explanation

To answer this, we need to note that two tangents to a circle that start from the same point usually have the same lengths.

So,

AD = AE = 6

CD = CF = 4

Since,

AB = 7 and AB = AE + EB

AE = 6

So,

AB = AE + EB

7 = 6 + EB

EB = 7 - 6

EB = 1

FB = EB = 1

So,

AC = AD + DC = 6 + 4 = 10

AB = 7

CB = CF + FB = 4 + 1 = 5

So, the perimeter of the triangle is given as the sum of all its exterior sides

Perimeter = AB + AC + CB

Perimeter = 7 + 10 + 5 = 22 units
