I think the answer is b. There is a population that is being studied.
Answer:
steam plot
Step-by-step explanation:
because the stem plot is easy to use
Solve<span> A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the </span>equation<span> by 2.</span>
Step-by-step explanation:

- Height ( h ) = 4.5 cm
- Base 1 ( b ) = 5.2 cm
- Base 2 ( b ) = 10.8 cm

- Area of the given trapezium
