Question

Vehicles passing over a bridge have two options for paying their bridge toll: paying with a live cashier or using a speed pass device affixed to the dashboard. data on a busy day for cars and trucks passing over the bridge are shown here. payment method live cashierspeed passtotal vehicle typecar3567102 truck184765 total53114167 what proportion of vehicles crossing the bridge are trucks and use speed pass? 0.2814 0.4123 0.6826 0.7231

Answer 1

The proportion of vehicles crossing the bridge that are trucks and use speed pass is 0.1616.

Step-by-step explanation:

The proportion of vehicles crossing the bridge that are trucks and use speed pass can be calculated by dividing the number of trucks using speed pass by the total number of vehicles crossing the bridge. In this case, the number of trucks using speed pass is 1847 and the total number of vehicles crossing the bridge is 11,416. Therefore, the proportion is calculated as:

Proportion = 1847 / 11,416 ≈ 0.1616

So, the correct answer is 0.1616. None of the options provided are correct.

Answer 2

The proportion of trucks using the speed pass to cross the bridge out of the total vehicles is 0.1078, which is not one of the options provided in the original question, possibly due to a typo or mistake.

Step-by-step explanation:

The proportion of vehicles crossing the bridge that are trucks and use the speed pass can be determined by looking at the numbers given in the data table. According to the table, 18 trucks used the speed pass. To find the proportion, this number should be divided by the total number of vehicles that crossed the bridge, which is 167. So the calculation should be: Proportion of trucks using speed pass = Number of trucks using speed pass / Total number of vehicles = 18/167 0.1078.
