The mean of the data without the outliers will be B 65.
Sum = n/2[2a + (n - 1)d] where a = first term, n = number of terms and d = common difference
(a) 30/2(2 x 5 + (30 - 1) x d) = 1455
10 + 29d = 1455 / 15
29d = 97 - 10
d = 87 / 29 = 3
(b) 7/2(2 x 9 + (7 - 1)d) = 0
18 + 6d = 0
6d = -18
d = -3

<span>For all rectangles with a fixed perimeter of p the rectangle with the maximum area is one where the length is p/4 and the width is p/4, in other words a square. The area of such a rectangle would be (p*p) /16.</span>
Answer:
-3,3.1, 3 2/10
Step-by-step explanation:
When you are putting different numbers from least to greatest, you need to put them in the same form...
First things first we should put -3 wayy up front. negative numbers are worth less than positive numbers.
Then we need to turn 3 2/10 into a decimal.
3 2/10 -------> 3.2
3.2 is more than 3.1
Thus, the order is
-3,3.1, 3 2/10
Hope this helps and have a nice day.
