Area of a triangle= 1/2 base times height
substitute
40=1/2*10*x
40=5x
x=8
the height is 8 inches
Answer:
0.064 = 6.4% probability that none of the 10 calls result in a reservation.
Step-by-step explanation:
For each call, there are only two possible outcomes. Either it results in a reservation, or it does not. The probability of a call resulting in a reservation is independent of other calls. So we use the binomial probability distribution to solve this question.
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.
24% of the calls to an airline reservation phone line result in a reservation being made.
This means that
Suppose that an operator handles 10 calls. What is the probability that none of the 10 calls result in a reservation?
This is P(X = 0) when n = 10. So
0.064 = 6.4% probability that none of the 10 calls result in a reservation.
A) angle A = 180-135= 45 degrees
Angles A and 135 are supplementary angles
b) angle B= 135 degrees
because the two 135 angles are vertical angles ( opposite angles made by two intersecting line)
c) angle C = 45 degrees
because angles C and angles A are corresponding angles since line (1) and line (2) are parallel
