jeremiah had a lemonade stand. The table shows how much lemonade he sold versus the tempature of the day. Which scatterpolt represents the data?
Temp: 78, 95, 79, 72, 65, 82, 68, 75, 89
Number of cups of lemonade: 15, 35, 22, 15, 10, 26, 10, 18, 34
Based on the given data, the scatterplot that represents the data would show an increasing trend between the temperature and the number of cups of lemonade sold. The higher the temperature, the more cups of lemonade sold.
A petting zoo graphed the average attendance of patrons every 10 days over a 100 day period of time. interpret the scattorplot to determine what type of association the scatterplot shows.
Scatterplot graph:
Days: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Number of Patrons: 725, 675, 700, 750, 650, 675, 700, 725, 725, 650
A: Linear Assocation
B: Positive Association
C: Negative Association
DL Non-Liner
Based on the scatterplot data provided, the scatterplot shows a non-linear association.
scatterplot graoh:
x axis: 5, 14, 23, 28, 30, 40, 47
y axis: 12, 14, 20, 24, 25, 31, 37
A: Linear Association
B: Non-linear association
C: Negative association
D: no association
A: Linear Association
The scatterplot shows a pattern that can be roughly approximated by a straight line, indicating a linear association between the x and y variables.
true or false: there is a relationship between the two sets of data
x axis: 65, 67, 68, 68, 69, 70, 70, 71, 72, 74, 74
y axis: 205, 210, 216, 218, 220, 223, 223, 230, 235, 240
True
There appears to be a relationship between the x and y data points as they are not random but show a trend, indicating there is a relationship between the two sets of data.
what is the equation in slope-intercept form for this trend line?
graph:
x axis: 1, 2, 5, 7, 10
y axis: 30, 35, 55, 60, 70
A: y=25x+5
B: y=5x+25
C: 1/5x+25
D: y=-25x+5
To find the equation in slope-intercept form for the trend line, we need to calculate the slope and y-intercept.
Using the points (1, 30) and (10, 70):
Slope (m) = (70 - 30) / (10 - 1) = 40 / 9
Now, substituting the slope into the slope-intercept form y = mx + b and using point (1, 30):
30 = (40/9)*1 + b
30 = 40/9 + b
b = 270/9 - 40/9
b = 230/9
Therefore, the equation in slope-intercept form for the trend line is:
y = (40/9)x + 230/9
None of the given options match the calculated equation, so the closest one is:
A: y = 25x + 5
However, it appears there was an error in the calculation. The correct equation should be:
y = (40/9)x + 230/9
Therefore, the closest match would be "none of the above" as provided options do not match exactly.
