D

Answer:

D.22%

Step-by-step explanation:

Hello, I think I can help you with this.

the proportion of red automobiles in the United States(P) is given by:

[tex]P=\frac{number\ of\ red\ automobiles }{number\ of\ automobiles\ in\ U.S.} *100%\\[/tex]

Step 1

According to the table

number of red automobiles =32+29+23

number of red automobiles =84

Step 2

number of  automobiles=32+29+23+18+36+25+4+17+11+25+26+39+10+46+33

number of  automobiles=374

Step 3

put the values into the equation

[tex]P=\frac{number\ of\ red\ automobiles }{number\ of\ automobiles\ in\ U.S.} *100\\P=\frac{84\ cars}{374\ cars}*100 \\\\\\ P=0.2245*100\\P=22.45\ percent\\\\P=22\ percent[/tex]

Proportion=22%⇒D.

Have a great day.
