Answer: c) There is not enough evidence to reject H0
Step-by-step explanation:
First, find the number of guitarists. 5/8*64=40.
Now, create an equation. x + 4x = 40
5x = 40
x= 8
There are 8 jazz solos and 32 classical solos.
Answer:
x= 3
Step-by-step explanation:
19x-5=7+15x
19x-15x=7+5
4x=12
x=12/4
x=3
Answer:
2x+20+3x+10 = 180 (int. angles, parallel)
5x+30 = 180
5x=150
x=30
