Answer:
An isosceles triangle that is not equilateral can not have an angle that measures 60°.
Step-by-step explanation:
An isosceles triangle that is not equilateral can not have an angle that measures 60°.
If we assume that one of the equal sides of the isosceles triangle is 60°, then another equal side will also be 60° and therefore, the third angle will automatically become (180° - 60° - 60°) = 60°.
Therefore, the triangle will become an equilateral triangle, which is not possible.
Again, if we assume that the unequal angle of the isosceles triangle is 60°, then the equal angles will also become 60° as degree.
Therefore, again the triangle will become an equilateral which is not possible. (Answer)
Answer:
a) Trials are independent, and there is a fixed number of trials, which means that the binomial probability distribution can be used.
b) 0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking
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.
a)
For each senior, there are only two possible outcomes. Either they disapprove daily pot smoking, or they do not. The seniors are selected at random, which means that the probability of one disapproving daily pot smoking is independent of other seniors, that is, the trials are independent. There is also a fixed number of trials.
b)
70% disapprove of daily pot smoking, according to a report in Parade, which means that
12 seniors means that
The probability is P(X = 1).
0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking
