Answer :
To determine John's CA (Completion Accuracy) percentage for the week, we need to follow these steps:
1. Determine the total number of intervals John selected.
2. Identify the number of intervals where he was on time and had no technical issues.
3. Calculate the percentage of successful intervals out of the total intervals selected.
4. Round this percentage to the nearest whole number.
Let's break down the information we have:
- John selected a total of 4 intervals.
- He was on time and had no technical issues with 3 of these intervals.
Now, we can calculate the percentage of successful intervals. The formula for calculating the CA percentage is:
[tex]\[ \text{CA percentage} = \left( \frac{\text{Number of successful intervals}}{\text{Total number of intervals}} \right) \times 100 \][/tex]
Substituting the values from the problem:
[tex]\[ \text{CA percentage} = \left( \frac{3}{4} \right) \times 100 \][/tex]
Perform the division:
[tex]\[ \frac{3}{4} = 0.75 \][/tex]
Then multiply by 100 to convert to a percentage:
[tex]\[ 0.75 \times 100 = 75\% \][/tex]
Finally, since we are asked to round to the nearest whole number, we observe that 75 is already a whole number.
Therefore, John's CA percentage for the week, rounded to the nearest whole number, is:
75%
From the provided options, the correct answer is:
- 75%
