Answer:
second difference
Step-by-step explanation:
The differences of the y-values will differ by a common amount.
<u>Example</u>:
y = x^2 for x = 2, 4, 6, 8
y-values are 4, 16, 36, 64
differences of these are 12, 20, 28
differences of these differences are 8 and 8, a common value.
Answer:
Just multiply
length x width = area
94 x 50 = 4700
Step-by-step explanation:
Answer:
5 classes.
Step-by-step explanation:
You can use the
rule to determine the number of classes for a frequency distribution.
The
rule says that
where
is the number of classes
is the number of the data points
We know that the number of data points is
= 20.
Next, we start searching for
so that we can get a number 2 to the
that is larger that the number of data points.

This suggests that you should use 5 classes.
We know that the true value for pi is given as 3.14156.
Now, we have been given that the approximate value for pi is 3.141
We know the formula
Absolute error, 
Relative error is given by
![\text{Relative error }= \frac{\Delta x}{\text{true value} }\\ \\ \text{Relative error }=\frac{0.00056}{3.14156} \\ \\ [tex]\text{Relative error }=0.000178](https://tex.z-dn.net/?f=%5Ctext%7BRelative%20error%20%7D%3D%20%5Cfrac%7B%5CDelta%20x%7D%7B%5Ctext%7Btrue%20value%7D%20%7D%5C%5C%0A%5C%5C%0A%5Ctext%7BRelative%20error%20%7D%3D%5Cfrac%7B0.00056%7D%7B3.14156%7D%20%5C%5C%0A%5C%5C%0A%5Btex%5D%5Ctext%7BRelative%20error%20%7D%3D0.000178)
