Answer: a. variation in the variable, HOURS SPENT STUDYING explains 43% of the variation in the variable. TEST SCORE
Step-by-step explanation:
The coefficient of determination is denoted by R square is the proportion of the variance in the dependent variable that is predictable from the independent variable.
Given: dependent variable = TEST SCORE
independent variable = HOURS SPENT STUDYING
coefficient of determination = 0.43
That means variation in the variable, HOURS SPENT STUDYING explains 43% of the variation in the variable. TEST SCORE.
Hence, the correct option is a.
First pick: 13/(13+19+8)=13/40
the second pick: 12/39
both: 13/40 *12/39=156/1560=0.1

Answer:
The answer would be C. or D.
Step-by-step explanation:
Answer:
Step-by-step explanation:
2(2x-1)=6(x+2) PEDMAS
4x-2=6x+12 subtract 4x from both sides
-2=2x+12 subtract 12
-14=2x divide by 2
x= -7
