It is a convenience sample because subjects are selected because of their closeness to the researcher.
Step-by-step explanation:
8x+6y=24
6y=24-8x
y=24/6 - 8/6x
y=4-4/3x
<h3><u>The value of h is equal to 81.</u></h3>
19 = (h/3) - 8
Multiply all terms by 3.
57 = h - 24
Add 24 to both sides.
81 = h
Answer:
Part A: 48in^2
Part B: 4in by 12in, 8in by 6in, and 3in by 16in
Step-by-step explanation:
Volume/height is the area of the base:
480/10 = 48in^2
Any two numbers that multiply to 48 are possible dimensions of the block:
4*12, 8*6, 3*16
