Answer:
b. the ranges of penguin heights are the same.
Step-by-step explanation:
Hello!
Statements:
Which statement correctly compares the spreads of the distributions?
a. the mode of penguin heights at county side zoo is greater than the mode at city view zoo.
b. the ranges of penguin heights are the same.
c. the range of penguin heights is greater at city view zoo than at county side zoo.
d. the range of penguin heights is greater at county side zoo than at city view zoo.
The mode and mean are measurements of central tendency, these indicate the position of a data set but don't show any information concerning the distribution of said data.
The range on the other had is a measurement of variance, it shows the difference between the maximum and minimum values of the data set and indicates its total dispersion.
City view Zoo R= 44-37= 7 cm
County side Zoo: R= 45-38= 7 cm
Both ranges are the same.
I hope this helps!
Answer:
(0, -8)
Step-by-step explanation:
The distance must be equal from C to A and points B to D.
First, we can simplify it down.
x = (-x + 6)^2
Then, you should have x - (
- 12x + 36).
Factor it to get x = 4 or 9. 4 works in the original equation but 9 does not.
x = (-x + 6)^2
Then, you should have x - (
