Four equations are graphed on the coordinate grid:

a coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. line a passes through the ordered pairs negative 8, 5 and 4, negative 7. line b passes through the ordered pairs negative 3, 8 and 2, negative 7. line c passes through the ordered pairs 0, 9 and negative 7, negative 5. line d passes through the ordered pairs 1, 4 and negative 4, negative 1 and is extrapolated further in the quadrant.

which set of equations has (−3, 0) as its solution?

a and b
b and d
b and c
a and d

If the simple annual interest rate on a loan is 6, what is the interest rate in percentage per month?

If np3 /nc2 = 6, find the value of n

Aresearch study is studying the effects of a new drug for osteoporosis alzheimer's disease (ad) for women above the age of 65 years. a group of individuals with osteoporosis is randomized into two groups. one group is treated conventionally, and the second group is treated with the new medication. assessments are made at 3, 6, 12, 36, and 48 months. the conventionally treated group is assessed for ad using a serum blood test, and the treatment group is assessed for ad using a pet radiotracer that binds to beta-amyloid plaques. in comparing these 2 trial arms, the authors of the study may encounter which type of bias? a. selection bias on the risk of developing b. measurement bias c. confounding bias d. recall bias e. lead-time bias
