Answer:

75

Step-by-step explanation:

The measure of two supplementary angles =  15:21

The angles are  15x , 21x

15x + 21x = 180       {Supplementary}

         36x = 180

             x = 180/36

             x = 5

Smallest angle = 15 * 5 = 75

Answer: Choice D)

He needs to square each deviation in the numerator.

==========================================================

Explanation:

The sample standard deviation involves these steps

The step 3 highlighted in bold is where Toby made an error. He subtracted xbar from each person correctly, but forgot to square those deviations. The squaring is done to ensure we don't have any negative deviations.

This is what his work should look like when calculating the sample standard deviation

Answer:

⠀

Explanation :

⠀

For a regular polygon of n sides, we have

[tex]\bf \longrightarrow \qquad Each \: exterior \: angle = { \bigg( {\dfrac{360}{n} } \bigg)}^{ \circ} [/tex]

⠀

Here, We are to find the measure of each exterior ange of a regular decagon.

⠀

⠀

Now, substituting the value :

⠀

[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{360}{10} } \bigg)}^{ \circ} [/tex]

⠀

[tex]\sf \longrightarrow \qquad Each \: exterior \: angle _{(Decagon)}= { \bigg( {\dfrac{36 \cancel0}{1 \cancel0} } \bigg)}^{ \circ} [/tex]

⠀

[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{36}{1} } \bigg)}^{ \circ} [/tex]

⠀

[tex] \pmb{\bf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = 36^{ \circ} }[/tex]

⠀

Therefore,

Answer:

It is 36 degrees because the out side is equal to 360 degrees

If you divide that by ten you get 36 for each angle

Answer:

13/29

Step-by-step explanation:

6 + 8 + 5 + 10 = 29

8 + 5 = 13

Step-by-step explanation:

We have our question.

f + 2.5= 3f + 7.24

Then you combine like terms that taking the coefficients apart.

That is,

NOTE: WHEN TAKING A NUMBER ACROSS AND EQUAL SIGN THE SIGN CHANGES, E.G - TO + .

f - 3f = 7.24 - 2.5

-2f = 4.74

Divide both sides by coefficient of f which is -2

-2f = 4.74

-2 -2

f = 8.49

Answer:

12-4=8

Step-by-step explanation:

12-4 = 8

The set of data 6, 2, 2, 2  will have the least dispersion from its mean.

From four sets of data, we take the mean of 6,2,2,2

[tex]\rm mean =\dfrac{ Sum \ of\ data}{Number \ of\ data}[/tex]

So the mean will be

[tex]\rm mean =\dfrac{ 6+2+2+2}{4}=\dfrac{12}{4} =3[/tex]

So the mean of the data (6,2,2,2) is 3 which has the least dispersion from its every data as compared to the other data

Thus the set of data 6, 2, 2, 2  will have the least dispersion from their mean.

Answer:

76 m

Step-by-step explanation:

The area of a rectangle = length × width.

If we know that the area is 4864m² and the width is 64m, we can substitute this into the formula:

4864 = length × 64

To find the length, all we have to do is divide the area by 64: length = 4864 ÷ 64 = 76 m
