A Norman window is a window with a semi-circle on top of regular rectangular window. What should be the dimensions of the window

Ymorist [56]

Answer:

1.68 ft

Step-by-step explanation:

Let x be the radius

Arc length = 3.14x

Width = 2x

Height = [12 - (2x) - 3.14x]/2

= 6 - 2.57x

Area = 3.14x²/2 + 2x(6 - 2.57x)

Area = 12x - 3.57x²

dA/dx = 12 - 7.14x = 0

x = 1.6806722689

Height = 6 - 2.57x

= 1.6806722689

The odds against Carl beating his friend in a round of golf are 7:5. Find the probability that carl will beat his friend.

Leya [2.2K]

Answer:

So if they play (7+5=12) 12 times, carl will win 5 times.

To find probability that carl will beat his friend, we take the probability of Carl winning. Simple!

The probability is 5/ 12
