A graph titled Monthly Sales and Advertising Costs has Advertising Costs (1,000 dollars) on the x-axis and sales (1,000 dollars) on the y-axis. A line goes through points (6.4, 117) and (6.6, 120). The slope of the trend line is 15. What does that mean in regard to the data of the scatterplot? Check all that apply. The slope represents the rate of change of the data. Advertising costs increase $15,000 as sales increase by $1,000. Sales increase $15,000 as ads increase by $1,000. A positive slope infers a negative correlation. A positive slope infers a positive correlation.

The data in the scatterplot on monthly sales and advertising costs, show that:
The slope represents the rate of change of the data. Sales increase $15,000 as ads increase by $1,000.A positive slope infers a positive correlation.What can be inferred from the graph on Monthly sales?In a linear model, the slope is used to depict the change in the value of y as a result of a change in x. If this slope is positive, then there is a positive relationship between the y and x values.
In this scenario, the slope is positive which shows that there is a positive relationship between sales and advertisements such that they both increase together.

Consider the line y = 7x-5.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answers
Answer:
[tex]\boxed {\sf Parallel: 7 }[/tex]
[tex]\boxed {\sf Perpendicular: -\frac{1}{7}}}[/tex]
Step-by-step explanation:
First, identify the slope.
We are given the line y=7x-5.
This is in slope intercept form or y=mx+b where m is the slope and b is the y-intercept. So, the coefficient to x, or 7 in this case, is the slope.
m=5Now, find the parallel and perpendicular slopes.
1. Parallel Slope
Parallel lines never intersect, so they have the same slope. A parallel line has a slope of 7.
2. Perpendicular Slope
Perpendicular slopes intersect to form right angles. They have negative reciprocal slopes.
Negate the slope: 7⇒ -7 Find the Reciprocal (flip the numerator and denominator: -7/1 ⇒ -1/7A parallel line has a slope of 7 and a perpendicular line has a slope of -1/7.
Answer:
I'll help
Step-by-step explanation:
Parallel lines have the same slope so it will be 7.
And perpendicular lines if you multiply them together they have to add up to -1,
So 7 you change it to its opposite which is 1 over 7 and yeah just

16 What value could you put in place of the x to make it a function? * (8, 7) (7,-6) (-4,5) (x, 9)
a) 8
b) 7
c) 9
d) -4
Answers
Answer:
(c) 9
Step-by-step explanation:
You can't have a repeated x-value in a function.
8 is taken by (8, 7)
7 is taken by (7,-6)
-4 is taken by (-4, 5)
9 is the only number that is not taken by any other point yet.
Remember that for a relationship to be a function it can't have repeated x-values. However, it doesn't matter to have the same x and y values!

The highway mileage (mpg) for a sample of 8 different models of a car company can be found below. Find

Mean =
Median =
Mode =
Standard Deviation =
Answers
Mean = 28.3 , Median = 28.5, Mode = 35, Standard deviation = 5.2
(All of the above are rounded off to one decimal place)
How to find mean, median, mode ?
The given data are : 20, 22, 26, 27, 30, 31, 35, 35
We know that, mean = (sum of samples)/(no. of samples)
= (20+22+26+27+30+31+35+35)/8
= 226/8 = 28.25 = 28.3 (approx)
Here, median = (sum of 4th & 5th sample)/2
= (27+30)/2 = 57/2 = 28.5
Since 35 appears highest number of times, i.e. 2 times, then we can say that mode is equals to 35
What is the required standard deviation ?Standard deviation = √{(20-28.3)²+(22-28.3)²+(26-28.3)²+(27-28.3)²+(30-28.3)²+(31-28.3)²+(35-28.3)²+(35-28.3)²}/8
= √{68.89+39.69+5.29+1.69+2.89+7.29+44.89+44.89}/8
= √(215.52/8) = √(26.94) = 5.190 = 5.2 (approx)

What is the average change in the helicopter's altitude
each second? Show your work.
Answers
Answer:
-9.33 ft per second
Step-by-step explanation:
To calculate this, you just have to divide -28 by 3. When doing this, it will give the change per second or for every 1 second.
-28/3 = -9.33
Therefore, the average change in the helicopter's altitude each second is -9.33 ft.

A good trick to have up your sleeve is to just memorize that the equation of a like is (y - y1) = m * (x - x1).
This equation describes a point that passes through (x1, y1) with a slope m. This point (x1, y1) does not have to be on the y-axis. Also, since the question told us they want m = slope = -1/4, all we have to do is plug stuff in.
(y - y1) = m * (x - x1) => (y - 4) = -1/4 * (x - 4), or answer D. Also note that the normal ‘x’ and ‘y’ here are variables. We can solve this equation for ‘y’ to give a more traditional format: y = -1/4x + 5.
helpp please! i don't understand this
Answers
Answer:
Step-by-step explanation:
Remark
This is actually a six sided figure. That really doesn't matter, but it's interesting to observe. It goes a long way to explaining what is going on. The trick to exterior angles is that as long as the figure is convex ( a closed figure whose lines do not cross), the exterior angles add to 360.
Once you know that, then you know that this figure must have 6 exterior angles and no matter how they are made, their total is 360.
Equation
n + n + n + n + 90 + 90 = 360 Combine like terms.
Solution
4n + 180 = 360 Subtract 180
4n = 360 - 180
4n = 180 Divide both sides by 4
4n/4 = 180/4
n = 45
