Hence angle AOE has a measure of 120 Degrees.
What is an Angle?An angle is a combination of two rays (half-lines) with a common endpoint.
How To Solve:When an angle is formed or drawn or opened clockwise , then we measure it using the upper scale of the protractor , and if the angle or its arc goes anticlockwise , we measure it using the bottom scale of the protractor.
According to the figure , the angle has been opened anticlockwise.
(Observe carefully , AOB , then AOC , AOD and so on. Suppose that O is the center of a clock and OA is the needle which is moving anticlockwise from position OA, OB, OC and so on).
So we will use the bottom or lower scale of the protractor. Line Segment OE of angle AOE is bisecting the Lower scale of the protractor at 120 degrees.
Hence angle AOE has a measure of 120 Degrees.

A track coach is gathering data on the stride length of each of her 52 team members when running a distance of 500 meters. The population
mean is 62.95 inches with a standard deviation of 5.65 inches.
What is the standard error of the sample mean? Round your answer to the nearest hundredth.
The standard error of the sample mean is approximately
Answers
The standard error of the sample mean is 0.7835140.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given:
Population mean = 62.95
Population standard deviation = 5.65
Sample size = 52
The standard error of the sample mean :
= Standard deviation / √(sample size)
= 5.65 / √(52)
= 0.7835140
Hence, the standard error is 0.7835140.

What is the approximate circumference of the coin? Use 3.14 as an estimate for Pi.
A-21 mm
B-3mm
C-66mm
D-84mm
Answers
Answer:
C. 66 mm (using 3.14, it would be 65.94 mm)
Step-by-step explanation:
From what I know, the radius of this coin is 10.5 mm.
The formula for the circumference of a circle is 2πr or πd.
In this case we're using 3.14 for π.
(2 * 10.5) * 3.14
21 * 3.14
21 * 3.14 is the same as 62.8 + 3.14
62.8 + 3.14
65.94 mm
This is close to 66 mm, which was C, so that is the answer.

A system of two linear equations has infinitely many solutions. One equation is x - 2y=6. Select the equation that
would make this system have infinitely many solutions.
A .x + 2y = 6
B .x-2y = 4
C . 2y-x= -6
D .- 2y + x=4
Answers
Answer:
C . 2y-x= -6
Step-by-step explanation:
A system of linear equations can have no solution, a unique solution or infinitely many solution.
We say two linear equations has infinitely many solutions when the result is true.
To determine if a system has infinitely many solutions, the coefficient of their respective variables (x and y) would be equal. Also the constant of both equations would be equal.
Given that x - 2y = 6
The coefficient of x is 1, coefficient of y is -2 and constant is 6. The equation with the same attributes is:
C . 2y-x= -6
2y - x = -6
multiply through by -1
x - 2y = 6
It is same as the above
Adding both x - 2y = 6 and 2y-x= -6 gives 0 = 0

A square with sides x ft long has a perimeter of 34 1/2 ft. How long are the sides of the square
Answers
Answer:
8.625 ft for each side.
Step-by-step explanation:
This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th is 9 (although i doubt saying 1th is right, but just because).

A new manufacturer joins the market and captures 10% of the market share and Splendor increases to 40% of market share.
Market shares:
Yamaha = 10%
Splendor = 40%
Passion = 100% - 10% - 40%

Find the value of r in(4,r) (r,3) so that the slope of the line containing them is 0
Answers
Answer:
r = 3.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope.
Finding the slope of a line, given two points:
When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.
Points (4,r), (r,3)
Change in y: 3 - r
Change in x: r - 4
Slope is 0, so:
[tex]\frac{3 - r}{r - 4} = 0[/tex]
[tex]3 - r = 0[/tex]
[tex]r = 3[/tex]
The value is r = 3.
