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.
B) 12 inches would be the most accurate measurement.
Since the ruler is exactly 1 foot long, the most accurate measurement is 12 inches. 12.005 is a tempting answer, since it is the most specific/exact, but 12 inches is the most accurate, since this is equal to exactly one foot.
Answer:
2x^2 + 8xy - 2y^2
Step-by-step explanation:
2X(X+y) + 2y(3X-y)
2x^2 + 2xy + 6yx - 2y^2
2x^2 + 8xy - 2y^2
You would input the variables to solve the equation. 10 + 12 x 4 - 5 and then use order of owrstiona to solve. The answer would be 53.
