The ratio of the measure of two supplementary angles is 15:21. What is the measure of the smallest angle?
Answers
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

6. What is the measure of each exterior angle
of a regular decagon?
a.45°
B.36°
C. 30°
d. 40°
Answers
Answer:
36° .⠀
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.
⠀
So, we know a regular decagon has 10 sides, so n = 10 .⠀
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,
The measure of each exterior angle of a regular decagon is 36° .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

The area of a rectangular field is 4864 m².
If the width of the field is 64 m, what is its length?
Answers
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

Which set of population data is the least dispersed from its mean? 2, 3, 2, 9 4, 0, 4, 0 6, 2, 2, 2 9, 3, 5, 3.
Answers
The set of data 6, 2, 2, 2 will have the least dispersion from its mean.
What will be the 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.

He needs to square each deviation in the numerator.
==========================================================
Explanation:
The sample standard deviation involves these steps
Find the sample mean xbar.Subtract the xbar value from each data point. This gets us the list of deviations or how far each person is from the mean.Square each difference in the previous stepAdd up the squares from step 3. This is referred to as the Sum of the Squared Errors (SSE)Divide the SSE over n-1. If Toby was doing a population standard deviation, then he'd divide over n instead of n-1. However in much of statistics, we don't know much about a population and instead rely on sample statistics.The result of step 5 gets the variance. Apply the square root to the variance to get the standard deviation.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
