Answer:
c. The score on the achievement test of both groups.
Step-by-step explanation:
A school psychologist recruits 600 second-grade students and randomly divides them into two groups.
Group 1 is taught by means of the new method, while Group 2 is taught via traditional methods.
We have to find the response variable. A response variable is the outcome variable or dependent variable in the experiment.
Here this is - The scores on the achievement tests of both group 1 and group 2.
Answer:
1.57 radians
Step-by-step explanation:
Divide both sides by 360, you get 1° = π/180. This means 70° is equal to (70)(π/180). Then simplify this, and 70° = (7π)/18 radians, or approximately 1.221730476396 radians. This seems reasonable because 90°, is a quarter circle and (1/4) of 2π is π/2, which is approximately 1.57 radians.
