F(x) represents how many books in total and x represents the number of days
Step-by-step explanation:
This is in the form of

in this case, x is 1 and y is 7. So ourbpoint would be (1,7.)
The last one is correct because 60+35+35+35=165
55+55+55=165
Answer:
a=0.1
Step-by-step explanation:
From the given frequency table, Fiction= Poetry+Prose=total
⇒0.2+0.8=1.0=total
And, Poetry+prose= total
⇒0.18+0.82=1.0= total
Thus, following the same path,we have
Non Fiction= Poetry+prose=Total
⇒a+0.9=1.0
⇒a=1.0-0.9
⇒a=0.1
Therefore, the value of a will be: 0.1
