Answer:
a) p = 352/700 = 0.5029
b) p = 348/700 = 0.4971
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
There are 700 shoppers.
151 + 201 = 352 were happy with the service received.
133 + 215 = 348 were not happy with the service received.
(a) A shopper was happy with the service received.
352 happy out of 700
p = 352/700 = 0.5029
(b) A shopper was unhappy with the service received.
348 unhappy out of 700
p = 348/700 = 0.4971
Step-by-step explanation:
Area of Sector
= θ/360° * πr² (degrees) or 0.5r²θ (radians)
Question 11:
- (88°)/360° * π(19)² = 277.23ft².
Question 12:
- (260°)/360° * π(11)² = 274.54mi².
Question 13:
- 0.5(6.2)²(7π/12) = 35.22km².
Question 14:
- 0.5(7.1)²(5π/3) = 131.97cm².
Question 15:
- (215°)/360° * π(4.5)² = 37.99yd².
Question 16:
- 0.5(21.4)²(13π/18) = 519.54m².
Answer:
30420ft
Step-by-step explanation:
We have to break the shape into two. So..
13 times 26=338
now the top..23-13=10
10 times 9 = 90
338 times 90 = 30420 ft
