Answer:
80°
Step-by-step explanation:
exterior angle = sum of two remote interior angles
27 + 53 = 80
For 9: All the angle should add up to 360 degrees.
So 152+50=202
360-202=158 degrees (Missing angle measure)
Method being used: All angle should add up to 360 degrees.
Answer:
d, no solutions
Step-by-step explanation:
The distance between 17 - 2 is = 15, so 16 would be the smallest possible whole number length for the third side.
Answer:
a. .0554
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.
The probability of success is .06.
This means that 
What is the probability of two successes in seven trials?
This is P(X = 2) when n = 7. So


The correct answer is given by option a.
