You and a group of friends want to know how many students in your school prefer rock music. There are 480 students in your school. Each person in the group randomly surveys 20 students. The table shows the results. Part A. use each sample to make an estimate for the number of students in your school who prefer rock music.
Part B. Describe the center and variation of the estimates

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

ιт ωιℓℓ вєтнє fιяѕт ¢нσι¢є(α.)

convert the exponential equation to a logarithmic equation using the logarithm base (6) of the right side (36) equals the exponent (2).

ℓσg6(36)=2
