Answer:
2/3 x 4/5 = 8/15
Step-by-step explanation:
The circumference of a circle is 2•3.14(Pi)•R(radius) or 3.14(Pi)•D(diamater).
Since we have our diameter, 60, we need to multiply it by Pi.
60Pi is your answer.
I hope this helps!
Answer:
AB = 8.857 cm
Step-by-step explanation:
Here, we are given a <em>right angle</em> 
in which we have the following things:
Side <em>BC </em>is the hypotenuse here.
We have to find the side <em>AB</em>.
Trigonometric functions can be helpful to find the value of Side AB here.
Calculating 
:
Sum of all the angles in is 
.
We know that <em>cosine </em>of an angle is:
So, side AB = 8.857 cm
.
Answer:
-3.649% or -0.0365
Step-by-step explanation:
A percentage can be converted to a decimal by moving the decimal point 2 places to the left.
-27.37% = -0.2737
Divide
-0.2737 / 7.5 = Answer
Answer: compare the relative strength of coefficients.
Step-by-step explanation: The Coefficient of determination usually denoted as R^2 is obtained by taking the squared value of the correlation Coefficient (R). It's value ranges from 0 to 1 and the value obtained gives the proportion of variation in the dependent variable which could be attributed to it's correlation or relationship to th independent variable. With a R^2 value close to 1, this means a large portion of Variation in a variable A could be explained due to changes in variable B while a low value signifies a low variance between the variables. Hence, the Coefficient of determination is used in comparing the relative strength of the Coefficients in other to establish whether a weak or strong relationship exist.
