Answer: The concentration of X is
and the concentration of Y is
.
Step-by-step explanation:
Since we have given that
At 272 nm, absorbance = 0.215
At 327 nm, absorbance = 0.191
As we have given that
Compound X Compound Y
272 16400 3870
327 3990 6420
So, our equations becomes

By solving these two equations, we get that

Hence, the concentration of X is
and the concentration of Y is
.
Days in a week n(S)=7
DAYS to not getting monday n(M)=6
probability P(M)=n(M)/n(S)
=6/7(ans)
You are inversing for subtraction which is addition so D
<span>(5 2/3+8 1/4)+9 3/4=n+18
</span><span>5 2/3+8 1/4+9 3/4=n+18
</span>5 2/3 + 18 = n + 18 | - 18
5 2/3 = n
