The total circle has a measure of 2π radian, so this portion is 1/(2π) of the whole circle
the circumference of the whole circle is 2πr
1/(2π) of 2πr=3.07
r=3.07
Answer:
4
Step-by-step explanation:
Answer:
The scale of y-axis is 10, and the scale of x-axis is 1.
Step-by-step explanation:
The y-coordinates of points J, K,L,M, and N are divisible by 10, so it would be convenient to scale the y-axis to 10, doing so will result in a graph that does not occupy too much space and is therefore easier to read.
The x-coordinates of points J, K,L,M, and N are integers less than 10. Our graph will be easier to read if we scale the x-axis to 1, because then we get a graph whose x-coordinate is marked such that the x values of the points can be easily related.
The sample mean is an estimate of the population mean.
The sample mean is exactly equal to the population mean
<h3>How to determine the true statement</h3>
When the population mean is known; the value of the population mean can be used as the sample mean.
This is so because:
The sample mean is an estimate of the population mean.
And it is represented as:
Hence, the true statement is that the sample mean is exactly equal to the population mean

Answer:
149°
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
<FRO + <RFO = <FOG
60° + 86 = 146
