Answer:
20%
Step-by-step explanation:
It would be 20% because 35/7 is 5 and 5 goes into 100% 20 times.
0.4^3 = 0.4 · 0.4 · 0.4 = 0.064
Answer:
16263 ways
Step-by-step explanation:
Given that:
Number of coin tosses, n = 15
Number of heads is between 8 and 12 inclusive
For 8 heads, tails = 15 - 8 = 7
15! / (8!7!) = 6435
For 9 heads, tails = 15 - 9 = 6
15! / (9!6!) = 5005
For 10 heads, tails = 15 - 10 = 5
15! / (10!5!) = 3003
For 11 heads, tails = 15 - 11 = 4
15! / (11!4!) = 1365
For 12 heads, tails = 15 - 8 = 3
15! / (12!3!) = 455
(6435 + 5005 + 3003 + 1365 + 455) = 16,263 ways
Sighting from Paula's location and the 42-degree angle, the height of the glider is the "opp side" of a triangle whose hypotenuse is 3280 ft.
The sine function best brings together the info we have and want:
sin 42 degrees = opp / hyp = height / 3280 ft.
Mult. both sides of this equation by 3280 ft, we get height = 2195 ft.
