Answer:
Each pack of gum costs $3
Step-by-step explanation:
We can set up the equation:
Each pack of gum can cost 4 or 3 dollars
We use the equation , where , , , and . We obtain from the z-score of a 0.97 confidence level.
D. 3
If the ratio of their sides is 4:1, and if PQ=12 inches, then Ab=12/4=3 inches.
h = V/lw
We know the formula for the volume of a rectangular prism is V = lwh. We need to use this equation and solve for h by dividing lw on both sides.
V = lwh
V/lw = h
