Answer:
a = 108°
b = 24°
Step-by-step explanation:
a) The pentagon will have interior angles of 540°/5 = 108°.
Angle a = 108°
__
b) The reflex angle at a vertex of the pentagon is 360° -108° = 252°. At the obtuse angle of the unshaded triangle, 120° of that amount is take up by two internal angles of the equilateral triangles. Those are 60° each. So, the obtuse angle in the unshaded triangle is ...
252° -120° = 132°
That triangle is isosceles, so the angle at b is ...
2b° +132° = 180°
b = (180 -132)/2 = 48/2 = 24
Angle b = 24°
Answer:
a = 108 °
b = 24°

Use the following data set to answer the questions below.
8, 15, 17, 19, 21, 82
1. What is the mean?
2. What is the median?
3. Is there an outlier? If so, what is the outlier?
4. What is the mean without the outlier?
Answer:
1.The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
2.The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.
3.There are no outliers. Explanation: An observation is an outlier if it falls more than above the upper quartile or more than below the lower quartile.
4.20. The "average" you're talking about is actually called the "mean". It's not exactly answering your question, but a different statistic which is not affected by outliers is the median, that is, the middle number. {90,89,92,91,5} mean: 73.4 {90,89,92,91,5} median: 90.

HELP ME Using the following equation, complete the square and find the center and radius of the circle:
x2 + y2 + 4x − 6y − 12 = 0
You must show all work and calculations to receive credit.
Answer: [tex](-2,3)[/tex], [tex]r=5\ \text{units}[/tex]
Step-by-step explanation:
Given
the equation is [tex]x^2+y^2+4x-6y-12=0[/tex]
completing the square
[tex]\Rightarrow (x^2+2\times 2\times x+4-4)+(y^2-2\times3\times y+9-9)-12=0\\\Rightarrow (x^2+2\times 2\times x+4)+(y^2-2\times3\times y+9)-12-4-9=0\\\Rightarrow (x+2)^2+(y-3)^2=25\\\Rightarrow (x+2)^2+(y-3)^2=5^2\\\Rightarrow (x-(-2))^2+(y-3)^2=5^2[/tex]
Thus, the center of the circle is [tex](-2,3)[/tex] and radius is [tex]r=5\ \text{units}[/tex]
Steve has a hammer that is 0.29 meters long. Which expression is equal to the length, in meters, of Steve's hammer?
Answer:
x = 0.29 m
Step-by-step explanation:
Given :
The length of the hammer is = 0.29 m
The hammer is a tool that may be used in various operation or work by mechanics, plumbers, or masonries and even by normal people.
So let the length of the hammer be x.
The length of the hammer is expressed in meters or inches or centimeters.
Therefore, the expression of length of the hammer is expressed as x = 0.29 m.

O logarithmic

O exponential
O linear
Answer:
Linear
Step-by-step explanation:
The type of function which is represented in the table is quadratic, the correct option is B.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The table
Now,
Looking at the table, we can see that each input value is paired with only one output value, so the relationship is a function. We can also see that the difference between the output values is not constant, so the function is not linear. The quotient of the output values is not constant either, so the function is not exponential. The quotient of the output values does not change in a predictable way, so the function is not logarithmic.
Therefore, by the function the answer will be quadratic.

write the following from least to greatest. 1/8, 2/4, 8/4, 3/15, 2whole 2/7, 20/10
Answer:
Step-by-step explanation:
Convert each number to its decimal equivalent for easier comparison with the other numbers:
1/8 = 0.125 1 (smallest)
2/4 = 0.50 3
8/4 = 2.0 4
3/15 = 0.20 2
2 2/7 = 2.28 6 (largest)
20/10 = 2.00 5 (next to largest)
The smallest number is 1/8 (see above), and the largest is 2.28 (2 2/7).

Emily works at a music store where she repairs guitars. She keeps track of the types of guitars she's fixed and the types of repairs she's made. Her records appear in the table below.
Calculate the following percentages based on the frequency table.
Round to the nearest hundredth of a percent.
Answer:
1. 31.3%
2. 34.35%
3.62.6%
Step-by-step explanation:
There were 131 acoustic guitars, and 41 of them needed neck repair.
41/131 = 0.3130 = 31.3%
There were 262 total guitars serviced by Emely. 60 of them were acoustic and needed a string repaired, and 30 of them ere acoustic and needed repair, so 90 of them were acoustic and did not need neck repair.
90/262 = 0.3435 = 34.35%
There were 131 electric guitars. 48 of them had a broken string and 34 of them needed body repairs. So 82 of them needed either string or body repairs.
82/131 = 0.6260 = 62.6%

There are two labeled weights of 4 grams and 12 grams the tree circles have the same weight what is the weight of each circle in grams
Answer:
The answer is below
Step-by-step explanation:
Let x represent the unknown weight of each of the circles, since there are three of those type of circles, hence the unknown weight is 3x.
From the diagram, the sum of the total weight at one side must be equal to the sum of the total weight at the other side so that they can be balanced, hence:
3x + 4 = 12
subtracting 4 from both sides:
3x + 4 - 4 = 12 - 4
3x = 8
Dividing through by 3:
3x/3 = 8/3
x = 8/3
The weight of each of the circle is 8/3 grams

Answer:
In mathematics, a set is closed under an operation if performing that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 is not a positive integer even though both 1 and 2 are positive integers.

The mean of the 5 data is 51.
(55 + 60 + 35 + 90 + x) ÷5 = 51
(240 + x) ÷5 = 51
240 + x = 255
x = 15
10.
The mean of the 5 data is 127.
(100 + 112 + 98 + 235 + x) ÷5 = 127
(545 + x) ÷5 = 127
545 + x = 635
x = 90
12.
The mean of the 5 data is 40.
(34 + 56 + 45 + 29 + x) ÷5 = 40
(164 + x) ÷5 = 40
164 + x = 200
x = 36
