Answer:

224 cm²

Step-by-step explanation:

Look at the figure below.

All sides are in cm. All areas are in cm².

Triangle A:

A = bh/2 = 8 × 21 / 2 = 84

Rectangle B:

A = LW = 9 × 8 = 72

Rectangle C:

A = LW = 4 × 5 = 20

Triangle D:

A = bh/2 = 6 × 16 / 2 = 48

Total area = 84 + 72 + 20 + 48 = 224

Answer: 224 cm²

Answer:

(a) Hypergeometric distribution

(b) 0.785384...

Step-by-step explanation:

(a) looking at the question, we see that $X = \in \{0, ... , 10 \}$ , suppose Evans studied s key terms, this implies that he has not studied 100 - s key terms. Suppose $k = \in \{0, ... , 10 \}$ if X = k, then k out of the s key terms he had studied appeared. But 10 - k out of 100 - s key terms he hasn't studied appeared. Thus X is an Hypergeometric distribution, X~HGeom(s, 100 - s, 10) with PMF:
