Point C is on side B D with point C slightly closer to point D. Segment A C drawn. Flow chart consisting of 4 rows of horizontal text boxes. A horizontal line segment joins the midpoints of each of the vertical sides of each of the text boxes effectively subdividing each text box into an upper box and lower box. In row 1 there is 1 textbox. In the upper half of the box is the equation the measure of angle B A D equals the measure of angle B A C plus the measure of angle C A D. In the lower half of the box is the number 1 in a smaller box. In row 2 there are 2 text boxes. In the upper half of the box on the left is the equation the measure of angle B A C equals 20 degrees. In the lower half of the box is the word Given. In the upper half of the box on the right is the equation the measure of angle C A D is 15 degrees. In the lower half of the box is the word Given. In row 3 there is 1 text box. In the upper half of the box is the equation the measure of angle B A D equals 20 degrees plus 15 degrees. In the lower half of the box is the phrase Substitution Property of Equality. In row 4 there is 1 text box. In the upper half of the box is the equation the measure of angle B A D equals 35 degrees. In the lower half of the box is the word Simplify. A ray is drawn from the text box in row 1 to the text box in row 3. A ray is drawn from each of the text boxes in row 2 to the text box in row 3. A ray is drawn from the text box in row 3 to the text box in row 4.
Answer:
Ruler Postulate
Step-by-step explanation:
In box 1, the reason that justifies the statement, m∠BAD = m∠BAC + m∠CAD, is: angle addition postulate.
What is the Angle Addition Postulate?The angle addition postulate states that the measure of a larger angle equals the sum of smaller angles that make up the larger angle.
∠BAD comprises of ∠BAC and ∠CAD.
Therefore, based on the angle addition postulate, m∠BAD = m∠BAC + m∠CAD.
The missing reason in box 1 would be: angle addition postulate.

Answer:
Step-by-step explanation:
Remark
If you take one radius whose length is r and start it at (0,0) on one end and (r,0) at the other, and sweep it around so the (r,0) hits every point on the circumference of the circle, the radius will go through 360°.
You have only gone through 120°. That's no problem. All you have to do now is add a fraction that adjusts for the 120°.
Formula
Arc length = fraction * 2*pi * r
2*pi * r is the circumference
Arc Length = 2* (120/360) * pi * r
Givens
r = 13
pi = 3.14
Solution
Arc Length = (120/360) * 2 * pi * 13
Arc Length = 27.21
Answer
Arc Length = 27.21

Answer: See below.
Good Luck! I hope this helps!
Step-by-step explanation:
1) Find the Mean of 7 18 9 22 4.
7 + 18 + 9 + 22 + 4 = 50
50 ÷ 5 = 10
2) Find the Median of 7 18 9 22 4.
4 7 9 18 22
The Median is 9.
3) Find the Mean of 7 3 7 4 8 9 2.
7 + 3 + 7 + 4 + 8 + 9 + 2 = 40
40 ÷ 7 = 5.7
4) Find the Median of 7 3 7 4 8 9 2.
2 3 4 7 7 8 9
The Median is 7.
5) Find the Mode of 7 3 7 4 8 9 2.
Mode is the number that occurs the most.
2 3 4 7 7 8 9
The Mode is 7.
6) Find the Median of 6 10 23 24 13 9 23 12.
6 9 10 12 13 22 23 24
There are 8 numbers in this set of numbers, so the Median is the average of the two numbers in the middle. So, [tex]\frac{(12+13)}{2} = \frac{25}{2} = 12.5[/tex]
The Median is 12.5.
7) Find the Mean of 6 10 23 24 13 9 23 12.
6 + 10 + 23 + 24 + 13 + 9 + 23 + 12 = 120
120 ÷ 8 = 15
The Mean is 15.
8) Find the Median of 120 113 101 101 112.
101 101 112 113 120
The Median is 112.
9) Find the Mean of 73 72 72 98 99 96 98 98 73.
73 + 72 + 72 + 98 + 99 + 96 + 98 + 98 + 73 = 779
779 ÷ 9 = 86.6.
10) Find the Mode of 73 72 72 98 99 96 98 98 73.
72 72 73 73 96 98 98 98 99
The Mode is 98.
11) Find the Mode of 6 10 23 24 22 9 23 13.

Determine the
period.
Explanation:
There are a few ways to measure the period. One way is to measure the horizontal distance from peak to peak.
The left peak occurs at x = 1
The right peak occurs at x = 17
This is a horizontal distance of 17-1 = 16 units.
Therefore, the period is 16. The curve repeats itself every 16 units.

Based on meteorological records, the probability that it will snow in a certain town on January 1st is 0.315. Find the probability that in a given year it will not snow on January 1st in that tow
The probability that in a given year it will not snow on January 1st will be P = 0.915.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Since the total probability is always equal to 1 if the probability of happening of an event is given then the probability of not happening of an event will be determined by subtracting it from one.
The probability of not any snowfall will be calculated as:-
P = 1 - 0.315
P = 0.615
Therefore the probability that in a given year it will not snow on January 1st will be P = 0.915.

Students in a school were asked to collect old bottles as part of a recycling drive. Some of the data recorded at the drive is shown in the histogram below:
Which information is not provided in the histogram?
The total number of students who collected bottles
The number of students who collected exactly 9 bottles
The number of students who collected 3 or fewer bottles
The total number of students who collected 7 or fewer bottles
Answer:
The number of students who collected exactly 9 bottles.
Step-by-step explanation:
The given histogram shows the number of students who participated in the recyling drive & their old bottle waste collection.
We can find out the total number of students who participated just by looking at the histogram (students = 10), the number of students who colected bottles below 7 or 3 bottles etc.
But since the number of bottles is given in the form of grouped data, one cannot infer the exact number of bottles collected by students.
Hence, out of the given statements, 'The number of students who collected exactly 9 bottles' is the incorrect one.

What is unitary mehtod?The unitary method is a process for solving a problem by first finding the value of a unit, and then finding the necessary value by multiplying the single unit value.
How to calculate how long would it take goblin Birt to count the coins in the bag by himself ?In this problem, unitary method is to be applied three times.Here, counting all the coins is considered as the entire work which is considered as 1.According to the problem,
Goblin gryh can count the coins in a bag in 10 minutes.∴ In 10 minutes Goblin gryh can count the coins in the bag.
∴ In 1 minute Goblin gryh can count [tex]\frac{1}{10}[/tex] th part of the coins in the bag.
Again, according to the problem,
Goblin gryh and Goblin Birt both can count all the coins in 6 minutes.∴ In 6 minutes, Goblin gryh and Goblin Birt both can count all the coins in the bag
∴ In 1 minute, Goblin gryh and goblin Birt both can count [tex]\frac{1}{6}[/tex] th part of the coins in the bag.
∴ In 1 minute, Goblin Birt can count [tex](\frac{1}{6} - \frac{1}{10})[/tex] th part of the coins in the bag.
