Answer:
4
Step-by-step explanation:
Prime factorization: 77=7*11
The horizontal component is:
17.1cos45.6≈11.96 so
vx=12.0 ft/sec (to nearest tenth ft/s)
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.
-5+2/3
= -5x 3
=-15+2/3
final answer =-13/3 > B
