Used the frequency table to determine how many students received a score of 60 or better on an English exam?
To determine the number of students who received a score of 70 or better on the math test, we need to sum the frequencies of the scores between 70-79, 80-89, and 90-99.
The frequency of the scores between 70-79 is 5.
The frequency of the scores between 80-89 is 7.
The frequency of the scores between 90-99 is 2.
So, the total frequency of scores of 70 or better is 5 + 7 + 2 = 14.
Therefore, the correct answer is (d) 14.
I apologize for my mistake. You are correct that there are a total of four games that had more than 40 points based on the stem and leaf plot:
- One game had a score of 42 (stem = 4, leaf = 2).
- One game had a score of 45 (stem = 4, leaf = 5).
- One game had a score of 58 (stem = 5, leaf = 8).
- One game had a score of 67 (stem = 6, leaf = 7).
Therefore, there are a total of four games that had more than 40 points. Thank you for correcting me.
i'm not on an english exam, i'm on a math test!!
I apologize for the confusion. Can you please provide me with the frequency table for your math test?
50-59, 2
60-69, 5
70-79, 5
80-89, 7
90-99, 2
No problem. To answer your question, we need to add up the frequencies for the scores of 60 and above.
So, for the scores of 60-69, we have a frequency of 5. For the scores of 70-79, we have another frequency of 5. And for the scores of 80-89 and 90-99, we have frequencies of 7 and 2 respectively.
Adding these frequencies together:
5 + 5 + 7 + 2 = 19
Therefore, we can conclude that 19 students received a score of 60 or better on the math test.
how many got 70+?
From the frequency table, we can see that there are 5 students who scored between 60-69 and 5 students who scored between 70-79. So, there are 5 + 5 = 10 students who scored 70 or above.
