Answer: -1 3/4
Step-by-step explanation
just add the fractions together :)
(between the -2 and -1 1/2)
The options are;
1) AB is bisected by CD
2) CD is bisected by AB
3) AE = 1/2 AB
4) EF = 1/2 ED
5) FD= EB
6) CE + EF = FD
Answer:
Options 1, 3 & 6 are correct
Step-by-step explanation:
We are told that Point E is the midpoint of AB. Thus, any line that passes through point E will bisect AB into two equal parts.
The only line passing through point E is line CD.
Thus, we can say that line AB is bisected by pine CD. - - - (1)
Also, since E is midpoint of Line AB, it means that;
AE = EB
Thus, AE = EB = ½AB - - - (2)
Also, we are told that F is the mid-point of CD.
Thus;
CF = FD
Point E lies between C and F.
Thus;
CE + EF = CF
Since CF =FD
Thus;
CE + EF = FD - - - (3)
Assuming you mean the sequence is given explicitly by
, the sum of the first 15 terms is
Recall Faulhaber's formulas, which say
Our sum is then
Sorry I'm not sure about this one
<span>Since these are done in order, and without replacement:
Lila selecting black = 7/12 (7 black ribbons out of 12 ribbons total)
Jessica *then* selecting a green ribbon = 5/11 ( 5 green ribbons left out of 11 ribbons left)
Chance of this specific event = (7/12)*(5/11) = 35/132</span>Mike <span>· 6 years ago</span>
