Step-by-step explanation:
Calculate the mean of this data set: 12, 35, 44, 74, 23, 49, 45, 18, 90, 56, 84,
Blababa [14]
Well, here is the mean of ur data collected 48.181818...
I believe it's the 3rd one
I hope this helps you
1/21+1/28=1/t
4/84+3/84=1/t
5/84=1/t
t=84/5
84/5 1
21 ?
?.84/5=1.21
?=5/4
Odd integers are represented by 2n+1 where n is a whole number
consecutive odd are 2 apart so
they are 2n+1 and 2n+1+2
the sum of them is at least 16
2n+1+2n+1+2<u>></u>16
4n+4<u>></u>16
minus 4
4n<u>></u>12
divide 4
n<u>></u>3
sub back
2n+1 and 2n+3
2(3)+1 and 2(3)+3
6+1 and 6+3
7 and 9
they have to be at least 7 and 9
