Answer:
8 births to 1sf
Step-by-step explanation:
4.2m births per year in unspecified country.
4.2 / 0.000365 = 11506.8493 per day
11506.8493 / 24 = 479.452054 per hour
479.452054 / 60 = 7.99086757 per minute = 8 births to 1sf
Answer:
65.3%.
Step-by-step explanation:
The general formula is:
nCr p^r (1 - p)^(n-r) where n = number of trials, p =probability of success on one trial , r = the given number of successes
So for 2, 3 or 4 success ;
probability = 5C2 (0.4)^2 (0.60)^(5-2) + 5C3 (0.4)^3 (0.60)^(5-3)
+ 5C4 (0.4)^4 (0.60)^(5-4)
= 0.3456 + 0.2304 + 0.0768
= 0.6528.
Answer:
60 degrees
Step-by-step explanation:
Since all sides are equal length, then all three angles are the same. In a triangle, the three angles should add up to 180. So 180 divided by 3 equals 60.
The answer is (2x+1)(x+3). HOPE THIS HELPED!
