The table is a linear regression model, and the equation of the regression model is y = 0.24x + 0.77
<h3>The scatter plot that represents the table</h3>
See attachment for the required scatter plot
<h3>The best model of the scatter plot</h3>
From the attached scatter plot, we can see that the points are almost on a straight line
Hence, the best model that fits the scatter plot is a linear model
<h3>The equation of the regression model</h3>
Using a graphing calculator, we have the following calculation summary:
- Sum of x = 28
- Sum of y = 12.1
- Mean X = 4
- Mean Y = 1.7286
- Sum of squares (SSX) = 28
- Sum of products (SP) = 6.7
- b = SP/SSX = 6.7/28 = 0.23929
- a = MY - bMX = 1.73 - (0.24*4) = 0.77143
The regression equation is represented as:
y = bx + a
So, we have:
y = 0.23929x + 0.77143
Approximate
y = 0.24x + 0.77
Hence, the equation of the regression model is y = 0.24x + 0.77

Answer:
B
Step-by-step explanation:
<em>the</em><em> </em><em>line</em><em> </em><em>pass</em><em> </em><em>through</em><em> </em><em>the</em><em> </em><em>point</em><em> </em><em>(</em><em>2.52</em><em>)</em><em> </em><em>and</em><em> </em><em>(</em><em>14.78</em><em>)</em><em> </em>
<em>So</em><em> </em><em>k</em><em>=</em><em> </em><em>78-52</em><em> </em><em>=</em><em>26</em><em> </em><em>=</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>4</em><em>-</em><em>2</em><em> </em><em>=</em><em>2</em>
Answer: The population of the town in 2015
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form)
x= years after 2006
A = population after t years
Replacing with the values given:
p(9) = 8,963 (1.03)^9
Since the years passed between 2006 and 2015 are 9 ( x), the equation represents the population of the town in 2015.

Step-by-step explanation:
1 bucket = 36 crayons
8 buckets = 36 × 8 = 288
288 is the total for all crayons.
a student took out 10 crayons of each bucket. each bucket have 36 crayons, so
36-10=26
now, each bucket only have 26 crayons in it.
So, there are still 8 buckets with 26 crayons in each bucket.
26×8 =208
