Answer is C.
The sample is selected at tandon from the population, but it was done on a particular day of the week. So the sample is not random.
More data should be taken, distributed on every day of the week, probably in different months.
B. Step 2 should’ve brought the negative sign down with the 72.
You can see that the equation went from -72 = 4x -30 to
72 = 4x - 30
Step-by-step explanation:
given
( x³ -64)/ x - 4
= (x³ - 4³) / x - 4
= (x - 4) ( x² + 4x + 16 ) / (x - 4)
( x- 4 ) will be cancelled out then
= x² + 4x + 16
X intercept make y =0
-4X+3(0)=-24
-4x+0=-24
-4x= -24
Dive by -4
X=6
Y intercept make X=0
-4(0)+3Y=-24
0+3Y=-24
3Y=-24
Divide by 3
Y=-8
