Given the frequency table, what percentage of the students in grades 9–10 like rap music? round to the nearest whole percent. band preference for school dance rap rock country row totals grades 9–10 40 30 55 125 grades 11–12 65 20 35 120 column totals 105 50 90 245

32%

Step-by-step explanation:

The given table in the correct format is attached in the image below. We need to tell what percentage of students from the grades 9 - 10 like rap music.

Total number of students in grades 9 - 10 = 125

Number of students in grades 9 - 10 who like rap music = 40

Percentage of students in grades 9 - 10 who like the rap music will be calculated as:

Using the given values in above expression we get:

This means 32% of the students in grades 9 - 10 like rap music

the answer is b

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
