Step-by-step explanation:
the sum of the angles = 360
8x+2 + 2x + 14 + 3x -4 +5x + 5 = 360
18x +17 = 360
18x = 343
x = 19.1
angles are:
154.8
52.2 smallest (2x + 14)
53.3
105.5
7.50h + 0.20s + 40
variable : an unknown number represented by a letter, such as h or s
coefficient : the number multiplied by the variable...in this case, could be 7.50 or 0.20.
constant : a number by itself, no variable...in this case, its 40
Answer:
P(X = 12) = 0.0064.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
We want P(X = 12). So
P(X = 12) = 0.0064.
