<u>Solution</u><u>:</u></h3>
Supplementary angles are those angles which add upto 180°. They may or may not be linear pair.
We have,
- Two consecutive odd angles.
- They are supplementary

Let,
- One of the angles be x
- Then, other angle will be x + 2°
Then,
➝ x + x + 2° = 180°
➝ 2x + 2° = 180°
➝ 2x = 178°
➝ x = 89°
Other angle = x + 2° = 91°
Answer - 89° and 91°
⚘ Hence, solved !!

D. <u>103 12/13</u> or about <u>104</u>
First sort the data into two sets of points, (1989,2881), (2002, 4232).
Now use the slope equation with your numbers.
(y2-y1)/(x2-x1)
(4232-2881)/(2002-1989)
1351/13=
<u>103 12/13</u><u> </u><u>or</u><u> </u><u>about</u><u> </u><u>104</u>
Answer:
D) 9
Step-by-step explanation:
7 x 2 - 4 - 9x
14 - 4 - 9x
10 - 9x
You could easily see at first that the coefficient of x is 9 because the coefficient is the number that is before the variable, but you can also do the whole process.

The probability that a randomly selected x-value from the distribution will be in the interval:
- P(35 < x < 45) = 0.6827 and,
- P(30 < x < 40) = 0.47725
<h3>What is the probability of a normal distribution?</h3>
The probability of a normal distribution can be determined from the symmetrical curve between 1 to 100%.
From the information given:
- Mean = 40
- Standard deviation = 5
To determine the probability that a randomly selected x-value is in the given interval:



![\mathbf{P(35 < x < 45) = P[Z\le 1] -P[Z\le -1]}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%2835%20%3C%20x%20%3C%2045%29%20%3D%20P%5BZ%5Cle%201%5D%20-P%5BZ%5Cle%20-1%5D%7D)
Using normal distribution table:
P(35 < x < 45) = 0.8414 - 0.1587
P(35 < x < 45) = 0.6827



![\mathbf{P(30 < x < 40) = P[Z\le0]-P[Z\le -2]}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%2830%20%3C%20x%20%3C%2040%29%20%3D%20P%5BZ%5Cle0%5D-P%5BZ%5Cle%20-2%5D%7D)
Using normal distribution table:
P(30 < x < 40) = 0.5 - 0.02275
P(30 < x < 40) = 0.47725
