Given:
The graph of a trend line.
To find:
The equation of the trend line.
Solution:
From the given graph it is clear that the trend line passes through the points (0,4) and (9,7). So, the equation of the trend line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-4=\dfrac{7-4}{9-0}(x-0)[/tex]
[tex]y-4=\dfrac{3}{9}(x)[/tex]
[tex]y=\dfrac{1}{3}x+4[/tex]
Therefore, the equation of the trend line is [tex]y=\dfrac{1}{3}x+4[/tex].

Find the measure of an exterior angle of the regular
polygon with 8 sides
Answer: 45°
Step-by-step explanation: The formula for finding the measure of each exterior angle of a regular polygon is simply 360/n where n represents the number of sides of the polygon.
Since our polygon has 8 sides, we plug 8 in
for n and we have 360/8, which is 45.
So our answer is 45°.

River Otters Drinks about 5 times as much as water as a bald eagle drink in a day
So we know that the bald eagle drinks 0.16 per day. (I am not sure liters, gallons, etc because it is not stated in the question.) Now, the question tells us that River Otters drink about 5 times MORE then the bald eagle. So first we need to multiply.
0.16 × 5 = 0.8
So river otters drink about 0.8 per day.
Now to find out how much a River Otter drinks in 3 days do:
0.8 × 3 = 2.4
Answer: River Otters drink 2.4 water in 3 days.
PS. Please check which unit it is and add the unit. Sometimes points get cut off without the units!
Find x, please. They’re vertical angles so x will be the same for both
Answer:
23.
Step-by-step explanation:
5x + 20 = 3x + 66
Subtract 20 from both sides and 3x from both sides
5x - 3x + 20 - 20 = 3x - 3x + 66 - 20
5x - 3x = 66 - 20
2x = 46
x = 23.

Price per ticket if it costs $279 for 9 tickets
Price per volleyball if 6 volleyballs cost $18.00
Number of strikeouts per inning if there were 54 strikeouts in 27 innings.
Answer:
$31 per ticket
$0.33 per volleyball
2 strikeouts per inning
Step-by-step explanation:
Price per ticket:
279 = 9x
Divide both sides by 9
31 = x
Price per volleyball:.
6 = 18x
Divide both sides by 18
6/18 = x
Both the numerator and denominator have a common factor of 6
6 ÷ 6 / 18 ÷ 6 = x
1/3 = x
Convert to decimal for money
0.33 = x
Number of strikeouts per inning:
54 = 27x
Divide both sides by 27
2 = x

Can someone give me a definition of Measure of center? Also, some facts/properties about it, example, and a non-example. Please? Thanks!
Answer:
A measure of central tendency (measure of center) is a value that attempts to describe a set of data by identifying the central position of the data set (as representative of a "typical" value in the set). We are familiar with measures of central tendency called the mean, median and mode.
Step-by-step explanation:
Some facts/properties are:
1. There are three measures of the “center” of the data. They are the mode, median, and mean. Any of the values can be referred to as the “average.” The mode is the data value that occurs the most frequently in the data
2. And to find the measure of center:
The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50 . To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.
3. The four measures of center are mean, median, mode, and midrange. ... Example: The median of 1, 3, 5, 5, 5, 7, and 29 is 5 (the number in the middle). Mode – The mode is the number that repeats most often in a data set. It's seldom used in statistics as a reliable measure of center.
I hope this helps :)

Answer
:Assuming you are talking about odium chloride,NaCl your answer would be
87.7 g
we discover the answer because 1 x 22.99 + 1 x 35.99= 58.4 g/mol
1.50 Moles:
We need to multiply our initial value by 1.50.
1.50 x 58.44/1= 87.66 = 87.7 g

Write and solve a inequality to represent the situation:
Answer:
5 people
Step-by-step explanation:
1. I subtract 5.10 from 45 which gave me 39.90
2. I divided 39.90 by 7 to figure out how many people he could buy for
3. I had gotten 5.7 so I had to round
4 final answer is 5
Answer:
Jamie can buy lunch for 5 people.
7p≤40
