If john must have a mark of 80% to past a test of 35 items, the number of items he may miss and still pass the test is

Question

Create an image depicting a classroom scenario, focused on a student, apparently named John, sitting at a desk with a stack of 35 question test papers next to him. In front of him, there is a calculator displaying the number 80% on its screen. Introduce diversity by making John a Black male student. Scatter seven items symbolically around the desk, representing the questions he might miss but still pass the test. Don't include any text in the image.

If john must have a mark of 80% to past a test of 35 items, the number of items he may miss and still pass the test is

Answer 1

He needs to make 80%, so if he misses (100-80)=20%, he still passes.

What is 20% of 35 items?

Answer 2

Hmm, let me calculate that for you. John needs an 80% to pass the test, which means he can afford to miss 20% of the items.

Now, let's convert that into the number of items. Since the test has 35 items in total, John can miss 20% of them.

So, if we multiply 35 by 20% (or 0.2), we get 7.

Therefore, John can miss 7 items and still pass the test. Just make sure he doesn't skip the most important one, because that might cause some serious clowning around!

Answer 3

To find the number of items John may miss and still pass the test, we need to calculate the maximum number of incorrect answers he can have and still achieve an 80% mark.

Step 1: Calculate the total score required to pass the test.
The passing score is 80% of the total marks.
Passing score = 80/100 * total marks

Step 2: Determine the total marks.
The total marks can be calculated by multiplying the number of items in the test by the maximum score for each item.
Total marks = number of items * maximum score per item

Step 3: Calculate the maximum score required to pass the test.
Maximum score = passing score / total marks

Step 4: Determine the number of items John may miss.
Number of items John may miss = total items - (passing score / maximum score)

Let's plug in the given values and calculate the result:
Passing score = 80/100 * 35 items = 28
Total marks = 35 items * 100% = 35
Maximum score = 28 / 35 = 0.8
Number of items John may miss = 35 - (28 / 0.8) = 35 - 35 = 0

Therefore, John may not miss any items in order to pass the test with an 80% mark.

Answer 4

To find the number of items John can miss and still pass the test, we can use the concept of percentage. If John must have a mark of 80% to pass the test, it means that he needs to answer at least 80% of the 35 items correctly.

To calculate this, we first need to find out how many items make up 80% of the 35 items. We can do this by multiplying 35 by 0.80 (which represents 80%).

80% of 35 items = 35 * 0.80 = 28 items

Therefore, John needs to answer at least 28 out of the 35 items correctly. The number of items he can miss can be calculated by subtracting this number from the total number of items.

Number of items John can miss = 35 - 28 = 7 items

John can miss up to 7 items and still pass the test.

If john must have a mark of 80% to past a test of 35 items, the number of items he may miss and still pass the test is

He needs to make 80%, so if he misses (100-80)=20%, he still passes.
