Step-by-step explanation:
there is no mathematical problem to solve.
just follow the instructions as given.
this is an exercise for you to get a feeling about what is what. it is imperative that you do it.
there is really nothing to solve.
remember, that a positive slope means the line goes up (from left to right), and a negative slope means the line goes down (again from left to right).
and I am sure you know what vertical and horizontal means.
Answer:
a = 16*3.1415/3 = 16.76
Step-by-step explanation:
a =pi*r^2
r =D/2
r = 8/2
r = 4
a = pi*4^2
a=pi16
pi = 3.1416
Answer:
the mode is 76, the median is 83, and the mean is 85.2
Step-by-step explanation:
Mode is the number which appears most often in a set of numbers.
To find the Median, place the numbers in value order and find the middle number.
To find mean add up all the numbers, then divide by how many numbers there are
To divide by a fraction, you invert the fraction and multiply so 480/(1/3)=480 times 3/1 or 1440
