Option A is the correct answer, y = x + 2

y - 3 = x-1

Please help. Thanks!

Answer:

84.9%

Step-by-step explanation:

First we need to calculate the total number of people. Total number of people will be the sum of all the given frequencies of all classes. There are 9 classes in total that are shown on the histogram

So,

Total number of people = 40 + 40 + 35 + 35 + 25 + 25 + 25 + 25 + 15 = 265

Now we need the number of people who took less than 40 seconds. This will be equal to sum of all frequencies below the time 40 seconds. i.e.

Number of people who took less than 40 seconds = 40 + 40 + 35 + 35 + 25 + 25 + 25 = 225

Formula to calculate percentage is:

$Percentage = \frac{\text{Desired Part}}{\text{Total}} \times 100\%$

So, percentage of people who took less than 40 seconds = $\frac{225}{265} \times 100\% = 84.9\%$

Thus, 84.9% of people took less than 40 seconds to complete the task.
