Answer:
See below
Step-by-step explanation:
The independent variable should be the size and the dependent variable the price.
This is the most logical approach if the manager wants to have an idea about what price could be adequate for future models with different sizes.
The first thing to do if we want to determine if there appears to be a relationship between the variables is to draw the scatter plot
<h3>(See picture attached)
</h3>
From the scatter plot we can tell that there is an apparent directly proportional relationship between size and price (the larger the size, the larger the price).
We could now try and compute the Pearson correlation coefficient r given by
where
are the sizes
are the prices
n = number of observations (7)
If we did so, we would find that<em> r = 0.9</em>, which tells us that there is a good linear correlation between size and price.

Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are always supplementary. But, two angles need not be adjacent to be supplementary. In the next figure, ∠3 and ∠4 are supplementary, because their measures add to 180° .
<h3>According to the question;</h3>
- ∠1 ≅ ∠2, which means that both angles are congruent or same.
<h3 /><h3>∠1 + ∠2=180°</h3><h3>∠1=180/2</h3><h3>∠1=90°</h3><h3>∠1 ≅ ∠2</h3><h3>90°=90°</h3>
- <em>Hence, values of ∠1 &∠2 are 90° respectively.</em>

Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 4 ← is in slope- intercept form
with slope m =
Parallel lines have equal slopes
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here (a, b ) = (- 1, 7 ) , then
y - 7 = (x - (- 1) ) , that is
y - 7 = (x + 1) → A
