suppelementary angles are angles that add to 180
remember that a straight line is 180 degrees so some angles that are supplementary are 1 and 2, 5 and 6, 1 and 5, 6 and 2, 3 and 7, 4 and 8, 7 and 8, 3 and 4
vertical angles are across from each other when 2 lines cross, they are like 5 and 2, 6 and 1, 7 and 4, 8 and 3

Answer:
0.3520
Step-by-step explanation:
We have been given that the pulse rates among healthy adults are normally distributed with a mean of 80 beats/second and a standard deviation of 8 beats/second. We are asked to find the proportion of healthy adults have pulse rates that are more than 83 beats/sec.
First of all, we will find z-score corresponding to sample score of 83 as:
, where,
z = Z-score,
x = Sample score,
= Mean,
= Standard deviation.
Upon substituting our given values in z-score formula, we will get:
Now, we need to find the probability that a z-score is greater than 0.38.
Using formula , we will get:
Using normal distribution table, we will get:
Therefore, 0.3520 of healthy adults have pulse rates that are more than 83 beats/sec.
Answer:

Step-by-step explanation:
Answer:
The correct answer is "". A further solution is provided below.
Step-by-step explanation:
According to the question,
The probability of getting a 5 will be:
=
=
The probability of getting a 7 will be:
=
=
The probability of not a 5 nor a 7 will be:
=
=
=
