Answer: Last option.
Step-by-step explanation:
Observe the figure attached.
In order to find the value of "b", you need to remember the definition of "Alternate interior angles". These are the pairs of angles located in the interior of the parallel lines and on opposite side of the transversal. They are congruent.
Based on this definition, you can conclude that the angle "b" and the angle that measures 128° are Alternate interior angles; therefore they are congruent.
This means that the value of "b" is:
I don't know what number 1 and number 2 mean,
3：11
4
5：-3
6：-8
You can find the answer below. Among the questions I answered correctly, I hope to adopt it at the end. Thank you. Have a nice day.
Answer:
The probability that R2 is bigger than R1 is P=0.9633.
Step-by-step explanation:
We need to compute the probability that R2 is bigger than R1:
To do this, we define a new variable Das the difference between the two resistances:
Then,
As R1 and R2 are normal random variables, the properties of D are:
Then, we can calculate the z-value for D=0
The drama club collected $198.75
The answer is reasonable because 75% of 212 is 159 and each ticket costs $1.25. So 159 tickets for $1.25 each is $198.75
