factor the 2 denominators:-
a^2 - 6a + 9 = (a - 3)(a - 3)
a^2 - 8a + 15 = (a - 3)(a - 5)
((a - 3) is common to both sets of factors so the LCD is:-
(a - 3)(a - 3)(a - 5) or this can be written as (a -3)^2(a - 5)
Well, for this question we can start off by making an equation
(6.4)2
This problem is quite simple actually so we will just multiply 6.4*2
6.4*2=12.8 miles
Answer:
The best measure of center for this dot plot is the median.
Choice A
Step-by-step explanation:
measures of center or location of a data set include;
the mean
the mode
the median
If a data set is symmetric or approximately normal then the best measure of center is the mean. On the other hand, for an asymmetric data with outliers the best measure of center is the median since it is robust to outliers.
Answer:
4 2/3
Step-by-step explanation:
2 , 4, 6, 5, 4, 4, 5, 4, 8
Add the data together then divide by the number of data points
(2 + 4+ 6+ 5+ 4+ 4+ 5+ 4+ 8) /9
42/9
4 2/3
