Only (a) describes a one-to-one function. (b) fails because
![f(a)=f(b)=b](https://tex.z-dn.net/?f=f%28a%29%3Df%28b%29%3Db)
; similarly, (c) fails because
![f(a)=f(d)=d](https://tex.z-dn.net/?f=f%28a%29%3Df%28d%29%3Dd)
.
I hope this helps you
1) 1/10.3=3/10=0,3

Answer:
exact form - b = -11/5
decimal form - b = -2.2
Mixed number form - b = -2 1/5
Answer:
P(R) = 0.14
P(I) = 0.16
P(D) = 0.315
Step-by-step explanation:
Let Democrat = D
Republican = R
Independent = I
If 45% are Democrats, 35% are Republicans, and 20% are independents, then
Total registered voters = 100
In an election, 70% of the Democrats, 40% of the Republicans, and 80% of the independents voted in favor of a parks and recreation bond proposal. That is,
D = 0.7 × 45 = 31.5
R = 0.4 × 35 = 14
I = 0.8 × 20 = 16
If a registered voter chosen at random is found to have voted in favor of the bond, what is the probability that the voter is
a Republican:
P(R) = 14 /100 = 0.14
an Independent
P(I) = 16/100 = 0.16
a Democrat
P(D) = 31.5/100 = 0.315
