"mean" just means arithmetic average...
(22+11+10+14+10)/5=13.4
"median" is the center term (if there is one) or the average of the two center terms in an ordered sequence...so our elements ordered are:
10,10,22,14,22 Since there is a single middle term 22, 22 is the median.
"mode" just refers to the element that occurs most in the set...10 appears twice so 10 is the mode.
Ummm yes please! Thanks so much!!! Merry Christmas

The answer to your question is 2/11
Answer:
1023.75
Step-by-step explanation:
The sum of a geometric sequence is
sum = a( 1 - r^n) / (1-r)
where a is the first term r is the common ratio and r^n is the nth term
We need to find the common ratio
r = 256/512 = 1/2
sum = 512 ( 1 - 1/2^12) / ( 1-1/2)
=512( 1-.000244141) / (.5)
=512(.999755859) /.5
=1023.75
3a - 4b = 21
check (-2 , -3)
3(-2) -4(-3) =21
-6 +12 = 21
6 does not = 21 so NO
check (0 , 7)
3(0) -4(7) =21
0-28=21
-28 does not equal 21 so NO
check (-3 , -2)
3(-3) -4(-2) =21
-9 +8 = 21
1 does not = 21 so NO
check (7 , 0)
3(7) -4(0) =21
21 = 21
Choice D
