To determine the number of students who scored 78, we need to analyze the given data. Let's break it down step by step:
Looking at the key, we can see that "8[2" represents the number 82. This means that any number in the form "8[x" corresponds to x2, where x is a single digit.
Now let's scan the data for the number 78. We can see that the number 78 is not explicitly mentioned in the given data. However, we can try to find any numbers that have a corresponding key in the form "8[x" that would equate to 78.
To figure out which number would correspond to 78, we need to solve the equation x2 = 78. Taking the square root of both sides, we find that x = √78. Since x must be a single digit, we can approximate √78 ≈ 8.8 to the nearest tenth.
Since there are no numbers between 8.0 and 8.9 in the given data, we can conclude that 78 is not present. Therefore, the correct option is:
