We have the following expression:
(x- (5/2)) ^ 2 = (13/4)
Let's rewrite the given expression:
x ^ 2 - 5x + 25/4 = (13/4)
x ^ 2 - 5x + 25/4 - 13/4 = 0
x ^ 2 - 5x + 12/4 = 0
x ^ 2 - 5x + 3 = 0
Answer:
the original equation given to Sam could have been:
x ^ 2 - 5x + 3 = 0
Answer: j=0.4
-j+0.8=-0.9j+0.76
-j+0.8+0.9j=-0.9+0.76+0.9j
-0.1j+0.8=0.76
-0.1+0.8-0.8=0.76-0.8
-0.1j=-0.04
-0.1j/-0.1=-0.04/-0.1
j=0.4
Ya have a good day.
Answer:
(C)81
Step-by-step explanation:
Total Number of Students =300
Percentage who had cats, n(C) = 40%
Percentage who had both cats and dogs ,
= 12%
Percentage who had neither cats nor dogs,
=45%
Now:
Universal Set, 

Therefore:
Number of Students who had dogs
=27% of 300
=81
