Answer:
c)
Step-by-step explanation:
Hi there!
A function, when it comes to discussing the degree of a polynomial one. We classify them accordingly to the highest exponent.
f(x)=-3x+2 (1st degree since -3x=-3x¹)
f(x)=0x² +3x-3 well, 0x²=0 then f(x)=0x² +3x-3=f(x)=3x-3 (1st degree Linear function with b≠ 0)
f(x) =-7x²-x+2 (2nd degree -Quadratic Function)
f(x)=2x³+2x²-4 (3rd degree -Cubic Function)
So it's the third one from top to bottom, or c) f(x)=-7x²-x+2

Answer:
39%
Step-by-step explanation:
It is given that 35 apartments have balconies in them.
While 55 apartments do not have balconies in them.
Total number of balconies is the sum of the apartments. i.e. 35 + 55
= 90 apartments
Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.
i.e.
= 0.38888888
Multiplying by 100, we get
= 0.388888 x 100
= 38.8888 %
= 39 %
