Answer: 37.5%
Step-by-step explanation:
From the given table, the total number of police vehicles= [tex]2+14+18+12+2=48[/tex]
The number of vehicles with speed between 46 and 50 miles per hour=18
Therefore, the percent of vehicles were traveling between 46 and 50 miles per hour
[tex]=\frac{\text{number of vehicles with speed between 46 and 50 miles per hour}}{\text{Total vehicles}}\times100[/tex]
[tex]=\frac{18}{48}\times100=37.5\%[/tex]
hence, the percent of vehicles were traveling between 46 and 50 miles per hour= 37.5 %
Answer : The percentage of the vehicles travelling at a speed of 46 to 50 miles per hour is, 36 %
Step-by-step explanation :
As we are given that a police officer records the speeds of vehicles on a road as follows:
Speed(miles per hour) 36-40 41-45 46-50 51-55 56-60
No. of vehicles 2 14 18 12 4
Number of vehicles travelling at a speed of 46 to 50 miles per hour = 18
Total number of vehicles = 2 + 14 + 18 + 12 + 4 = 50
Now we have to calculate the percent of the vehicles were traveling between 46 and 50 miles per hour.
% of the vehicles traveling between 46-50 mile/hr = [tex]\frac{18}{50}\times 100[/tex]
% of the vehicles traveling between 46-50 mile/hr = 36 %
Therefore, the percentage of the vehicles travelling at a speed of 46 to 50 miles per hour is, 36 %
