A part of a promotion student participate in a survey or mailed a free pass for one of three activities, movies, rollerskating or bowling participants have an equal chance of receiving each type of pass 900 students participate. How many would expected to receive a pass for rollerskating
2/3
600
450
300
300 students would be expected to receive a pass for rollerskating.
Since there are three activities being offered and each student has an equal chance of receiving a pass for each activity, the total number of students expected to receive a pass for each activity would be 1/3 of the total number of students participating.
1/3 of 900 is 300.
On a math test Samantha missed four out of the 20 questions. What is the relative frequency of the correct responses?
To find the relative frequency of the correct responses, we first need to determine how many questions Samantha answered correctly.
She missed 4 out of 20 questions, so she answered 20 - 4 = 16 questions correctly.
The relative frequency of correct responses can be found by dividing the number of correct responses by the total number of questions, then multiplying by 100 to get a percentage.
(16 correct responses / 20 total questions) * 100 = 0.8 * 100 = 80%
So, the relative frequency of correct responses is 80%.
