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.
X - unit of length
w,l - the sides of a rectangle
7 : 2 ⇒ 7x : 2x
Perimeter: P = 207cm
Perimeter: P = 2w + 2l
therefore: 2w + 2l = 207 |divide both sides by 2
w + l = 103.5 (cm)
w : l = 7 : 2 ⇒ w : l = 7x : 2x ⇒ w = 7x; l = 2x
subtitute
7x + 2x = 103.5
9x = 103.5 |divide both sides by 9
x = 11.5 (cm)
7x = 7 · 11.5cm = 80.5cm
2x = 2 · 11.5cm = 23cm
w = 80.5cm; l = 23cm
Area = wl
Area: A = 80.5cm · 23cm = 1851.5cm²
5x-2y=6
Slope intercept form y = mx + b
So
5x-2y=6
2y = 5x - 6
y = 5/2 x - 3
Answer
Slope intercept form: y = 5/2 x - 3
