Answer:
About 706.5 or 707
Explanation:
3.14 • 5² (5² is also 25) = 78.5
78.5 • 9 = 706.5 or 707
Edit: Also posted a better picture for explanation. See the attachment.
A = (a+b)/2
2*A = 2*(a+b)/2 ... multiply both sides by 2
2A = a+b
2A-a = a+b-a ... subtract 'a' from both sides to isolate b
2A-a = b
b = 2A-a
Answer: b = 2A-a
Answer:
20
Step-by-step explanation:
There are 20 ways to select 3 cups from the 6 cups.
This can be calculated using formula nCr
Where,
n = objects
r = sample
Calculating 6C3 using calculator that is 20.
Solution:
we are given that
A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the schoo. The order of selection does not matter.
As we know
6 teacheras can be selected out of 30 teacher in
ways.

Hence the required number of ways is 593775.
So So sorry, I answered so late xd
The mean can be found by adding all the numbers then dividing it by the amount of numbers
The mean for team A is about 7.7
and the mean for team B is about 7.6
So they're A.) About the same
To find the range find the biggest number then subtract it by the smallest
Team A: 12,0 ; 12 - 0 = 12
12 is the range
Team B: 12,3 ; 12 - 3 = 9
The answer is B.) <span>much greater for conference a than for b</span>
