Answer:
its B
Step-by-step explanation:
They are all direct variations
Answer:
The correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.
Step-by-step explanation:
Averaging data into blocks (in this scenario, by State) tends to a reduction in variation and an increase in correlation between the studied variables. Therefore, when applying regression to the original individual data, a reduced correlation would be expected:
Therefore, the correlation between the Math SAT and the Verbal SAT computed from the data on all the individuals who took the tests would be less than 0.97.
Answer:
wait ill work this out for you
Step-by-step explanation:
Based on the given equation above, get the value of x first so that this value can be substituted to the second equation. Value of x can be obtained by taking the arc sin of 7/11 which gives an answer of 39.52 degrees. Substituting this value to the second equation cos (90-39.52) gives an answer equals to 7/11
