These angles are equal due to the interior angles rule in which alternating interior angles are congruent
therefore 5x+12=117
5x=105
x=21
Answer:
The answer is the same as the explanation
Step-by-step explanation:
First at point B create a line that is the distance of AB that stops at C and make sure the angle on the inside is 90 degrees and then do the same with A to point D. Then connect point C and D making a perfect square.
Answer:
916.08
Step-by-step explanation:
132% *694 =
(132*694)/100 =
91608/100 = 916.08
Answer:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409.
Step-by-step explanation:
We can model this question with a binomial distribution random variable.
The sample size is n=60.
The probability that the relay come from supplier A is p=2/3 for any relay.
If we use a normal aproximation, we have the mean and standard deviation:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409:
