In a survey of 50 monthly bus rider, 16 were satisfied with the service. if there 750 monthly bus riders, how many can be expected to be satisfied with the service?
We can use proportions to solve this problem.
Let x be the number of monthly bus riders who are satisfied with the service.
From the survey, we know that:
16/50 = x/750
To solve for x, we can cross-multiply:
50x = 16 * 750
50x = 12,000
x = 240
Therefore, we can expect 240 monthly bus riders to be satisfied with the service.
To find out how many monthly bus riders can be expected to be satisfied with the service, we can use proportions.
First, let's determine the proportion of satisfied bus riders in the sample:
Proportion of satisfied bus riders = Number of satisfied bus riders / Total number of bus riders in the sample
Proportion of satisfied bus riders = 16 / 50
Next, let's use this proportion to estimate the number of satisfied bus riders in the population:
Number of satisfied bus riders in the population = Proportion of satisfied bus riders * Total number of bus riders in the population
Number of satisfied bus riders in the population = (16 / 50) * 750
Now, let's calculate:
Number of satisfied bus riders in the population = (16 / 50) * 750
Number of satisfied bus riders in the population = 0.32 * 750
Number of satisfied bus riders in the population = 240
Therefore, it can be expected that approximately 240 monthly bus riders will be satisfied with the service.
To find out how many of the 750 monthly bus riders can be expected to be satisfied with the service, you can use proportions to determine the approximate number.
First, let's establish a ratio between the number of satisfied riders and the total number of riders in the survey:
Number of satisfied riders / Total number of surveyed riders = Ratio of satisfied riders
From the given information, we know that 16 out of 50 monthly bus riders were satisfied with the service. So the ratio of satisfied riders is:
16 / 50 = 0.32
Now, we can use this ratio to estimate the number of satisfied riders among the 750 monthly bus riders:
Estimated number of satisfied riders = Ratio of satisfied riders * Total number of monthly bus riders
Estimated number of satisfied riders = 0.32 * 750
Estimated number of satisfied riders = 240
Therefore, it can be expected that approximately 240 of the 750 monthly bus riders would be satisfied with the service.
