Answer:
Step-by-step explanation:
To find the vertex, change the following equation into graphing form (vertex form)
(x-3)^2-4 - graphing form
The vertex is (3,-4) because you find the x intercept by doing the opposite of -3, and -4 is in the equation.
vertex=
(3,-4)
Answer:
it is -12
Step-by-step explanation:
Answer:
diameter ≈ 11 feet
Step-by-step explanation:
The area (A) of a circle is calculated using the formula
A = πr² ← r is the radius
To find r divide both sides of the equation by π
r² =
=
Take the square root of both sides
r =
≈ 5.5 feet
Diameter = 2r = 2 × 5.5 = 11 feet
189 because 20.7 rounds to 21 and 9.18 rounds to 9
21 * 9 = 189
If we plot the data on the graph, we can see that the
data is skewed to the right (positive skew) and there is an outlier. In skewed
data and presence of outlier, the median is most commonly used measure of
central tendency. This is because a positive skew would result in a positive
bias to the mean. Meaning that it would be a lot larger than the median and not
really representing the actual central tendency. The median however is less
affected by the skew and outliers.
Answer: Median, because the data are skewed and there is
an outlier
