I'm giving the number of students who prefer classical music is 64. what would be the relative frequency? round the answer to two decimal places if needed. (1 point) a.0.64 b.0.25 c.0.09 d.0.11

So first we need to find approximately the number of total students.

Rock I would say is about 200 people. Country, 100, Rap, 255, Classical, 64 as said before, and Blues, 80.

So if we add these all up we can find the total students.

200 + 100 + 255 + 64 + 80

699

Now the relative frequency is how many times something appears in a group.

Classical appears 64 times in about 700 people.

So, 64/700, is closest to the 0.9 selection.

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
