It's 42, here's a quick trick to do this, so we know there's 7 movies, and to find the combination we know we can't choose 2 of the same movie, so to make this part easier , in your head take one movie from the stack out of the stack now there's 6 movies. It's now just the "plug and play" step , (7)*(6)=(42)
I'm sorry If this is to long of an explanation, but I hope that this helps you understand on how to do this problem. Have a nice day :)
Answer:
22,332
Step-by-step explanation:
Put 6 where t is in the equation and do the arithmetic.
... y = 5500 ln(9·6 +4) = 5500 ln(58) ≈ 22,332
28% because 25x4=100 7x4=28
Answer:
17pi/15
Step-by-step explanation:
s = r *theta where r is the radius and theta is the central angle in radians
Convert 51 to radians
51 * pi/180 = 51pi/180
s = 4 * 51pi/180
= 17pi/15
