1. Lake Turkana is in the Great Rift Valley in northwest Kenya. As part of a study of water quality, the water temperature in the lake was measured at different depths. The data are shown in this scatter plot.

a. 26° C

b. 40m

c. Yes

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

a. What was the approximate temperature at a depth  of 70 m? At the surface?  

26° C

b. At what depth was the temperature  a little more than 27°C?

40 m

c. Do the points in the scatter plot show a relationship?  Explain your thinking.

Yes, the scatter plot show a relationship between the depth and the temperature of Lake Turkana. It shows a negative correlation between the two variables. The deeper the lake is, the cooler the temperature .

Hope it will find you well.
