To determine how many seniors are expected to attend graduate school, calculate \( \frac{2}{5} \) of 750.

1. Divide 750 by 5:
\( 750 \div 5 = 150 \).
2. Multiply the result by 2:
\( 150 \times 2 = 300 \).

Thus, 300 seniors (option C) would be expected to attend graduate school.

doubao C. 300 seniors. If 2 out of 5 seniors go on to graduate school, the fraction is 2/5. To find out how many out of 750 seniors, we multiply 750 by 2/5 = 300. C
minimax To find the expected number of seniors attending graduate school, we multiply the total number of seniors by the fraction that goes on to attend graduate school.

The fraction is 2 out of 5, which can be written as 2/5. So we calculate:

(2/5) * 750 = 2 * (750/5) = 2 * 150 = 300

Therefore, the expected number of seniors attending graduate school is 300.

根据题目,大约五分之二的毕业生会继续上研究生,即概率为2/5。如果学校有750名毕业生,那么预期会有多少人继续上研究生呢?我们可以通过将总人数乘以该概率来得出答案。也就是750*(2/5)=300,因此,预期有300名毕业生会继续上研究生。所以答案是C、300 seniors。

zhipu To solve this problem, we need to find out what fraction of the 750 seniors would be expected to attend graduate school. The given fraction is 2 out of 5, which means \( \frac{2}{5} \).

Next, we calculate \( \frac{2}{5} \) of 750:

\[ \frac{2}{5} \times 750 = 2 \times \frac{750}{5} \]

First, divide 750 by 5:

\[ 750 \div 5 = 150 \]

Then multiply by 2:

\[ 2 \times 150 = 300 \]

So, the number of seniors expected to attend graduate school is 300.

The correct answer is:

C. 300 seniors

deepseekv3 To solve this problem, we calculate the number of seniors expected to attend graduate school by multiplying the total number of seniors by the fraction that typically attends graduate school.

Given:
- Total seniors = 750
- Fraction that attends graduate school = 2/5

Calculation:
\( 750 \times \frac{2}{5} = 300 \)

Therefore, the expected number of seniors attending graduate school is 300.

Answer: **C. 300 seniors**
