Answer:
Ŷ = 1.3082X + 3.3436
Step-by-step explanation:
Given the data :
X : 11, 12, 4, 6, 13, 14, 8, 10, 7, 5, 9
Y : 18.69, 19.17, 6.13, 11.37, 19.31, 19.31, 15.28, 17.88, 13.49, 8.91, 16.75
Using technology, the data above gave the resulting linear regression model :
Ŷ = 1.3082X + 3.3436
Slope of model = 1.3082
Intercept = 3.3436
Scatter plot is attached below :
What we first want is to find two factors of 288
We can divide by two, to get 2 and 144
We can divide by four, to get 4 and 72
To make a negative after multiplying numbers, we need at least one number to have a negative before it
- x - = +
+ x - = -
+ x + = +
Using the above information we can put together the following equations
-288 =
-72 x 4
-4 x 72
-2 x 144
-144 x 2
There are more answers to this question, just find factors of 288 and make sure one of them is a negative.

Answer: Angle A = 34 degrees</h3>
================================================
Explanation:
Check out the diagram below.
Segment BD cuts angle EBC in half
So the two smaller pieces DBC and DBE are congruent. Let's call them x.
Let's make y = angle EBA.
Note how the diagram shows the angles x, x, and y forming a straight angle. So we can say
x+x+y = 180
2x+y = 180
y = -2x+180
We'll use this later.
For now, focus on triangle DEB. Angle E is 90 degrees and angle B is x.
D+E+B = 180
28+90+x = 180
x+118 = 180
x = 180-118
x = 62
Which means
y = -2x+180
y = -2*62+180
y = -124+180
y = 56
Now focus on triangle BEA. We have B = 56, E = 90 and A = z
B+E+A = 180
56+90+z = 180
146+z = 180
z = 180-146
z = 34
which is the measure of angle A.
