Scatter plot has one dot for each data point. Create a graph with the known variable along the x axis and the dependent variable along the y axis. In this case latitude for a city is unchanging so it belongs on the x axis. Temperature on the y axis. Use the highest and lowest value from each list to determine the scale 25 to 45 latitude and 32 to 76 degrees temp. So I chose 25 to 50 for latitude and 30 to 80 for temperature. Plot the points on the graph. I labeled them for clarity but this is not a necessary feature of a scatter plot. Then you use the assigned method to determine the slope and intercept of the trend line. I used Excel. You can use a scientific calculator or the pencil/paper algorithm. The slope is -2.48. Which means that change of +1 latitude results in lower temperature by 2.48 F
At latitude zero, expected temp is 137. This highlights the problem of extrapolation, which is a side issue. Plugging latitude 50 into the resulting equation yields 13.6 degrees F. NB both latitude and temperature are measured in “degrees” but these are vastly different. I left the unit off latitude to avoid this confusion.

Answer: 79 degrees

Step-by-step explanation:

4x+1 + 3x+4 = 180

7x + 5 = 180

7x = 175

x = 175:7 = 25

m8 = 3x + 4 = 3*25 + 4 = 79

Akimi4 [234]

Answer:

Step-by-step explanation:

This probability will be the area of the square divided by the area of the circle.

P=\frac{(4\sqrt{2})^2}{\pi 4^2}\\ \\ P=\frac{32}{16\pi}\\ \\ P=\frac{2}{\pi }\\ \\ \text{As a percentage}\\ \\ P=\frac{200}{\pi}\\ \\ P\approx 63.7\%

After 2 weeks, a plant is 9 centimeters tall. After 5 weeks, it has grown to 15 centimeters. If the plant grows at constant rate
Reil [10]

Answer:

y = 2x + 5

Step-by-step explanation:

First, find the slope using rise over run, (y2 - y1) / (x2 - x1)

With this information, we can create 2 points: (2, 9) and (5, 15)

Plug in the points:

(15 - 9) / (5 - 2)

6 / 3

= 2

Plug in the slope and a point into y = mx + b, and solve for b:

y = mx + b

15 = 2(5) + b

15 = 10 + b

5 = b

Plug in the slope and b into the equation:

y = 2x + 5 is the equation of the line
