Answer: 240
Step-by-step explanation:
As per given ,
Number of choices for Receiver = 5
Number of choices for CD Player= 4
Number of choices for Speakers = 3
Number of choices for Cassette Deck =4
If a switch board display in the store allows a customer to hook together any selection of components , then by product rule
The number of ways one component of each type be selected = (Number of choices for Receiver) x (Number of choices for CD Player) x (Number of choices for Speakers )x (Number of choices for Cassette Deck)
= 5 x 4 x 3 x 4 = 240
Hence, the answer is 240.
(b) is the best comparison
Answer:
Missing side = 6.7cm
Perimeter = 42.438cm
Step-by-step explanation:
The missing side will be the diameter of the semicircle
Missing side = 9.2cm - 2.5cm
Missing side = 6.7cm
Perimeter of the figure = Perimeter of rectangle + Circumference of the semi circle
Perimeter of rectangle = 2(L+W)
Perimeter of rectangle = 2(9.2 + 1.5)
Perimeter of rectangle= 2(10.7)
Perimeter of rectangle = 21.4cm
Get the circumference of the semicircle
Circumference of the semi circle= πd
Circumference of the semi circle = 3.14 * 6.7
Circumference of the semi circle = 21.038
Perimeter of the figure = 21.4cm + 21.038cm
Perimeter of the figure = 42.438cm
