Answer:
shaded area = 8.7 ft²
Step-by-step explanation:
area of circle = πr² = (3.14)(4²) = 50.24 ft²
apothem of hexagon = (sin 60° x 4) = 3.464
area of hexagon = 1/2(3.464)(6)(4) = 41.56 ft²
50.24 - 41.56 = 8.68 ft²
2 ham/wheat 5 ham/white 9 ham/rye 4 turkey/white 5 turkey/wheat 5 turkey/rye
I think this is right
The answer is B. 34.281
22.854 + 5(22.954) = 137.124
137.124 divided by 4 = 34.281 = 34.2810
Answer:
2.25
Step-by-step explanation:
The total frequency is:
20 + 12 + 6 + 2 = 40
Calculate the probability of each score:
P(X=3) = 20/40 = 0.50
P(X=2) = 12/40 = 0.30
P(X=1) = 6/40 = 0.15
P(X=0) = 2/40 = 0.05
So the expected value is:
E = (3)(0.50) + (2)(0.30) + (1)(0.15) + (0)(0.05)
E = 2.25
