The correct answer is the last one
To divide fractions, we do Keep, Change, Flip. Keep means that we keep the first fraction the same ( which is 8/1). Then for Change, we change the division sign to a multiplication sign. After that we Flip the second fraction itś reciprocal (or multiplicative inverse).
So your equation would be:
8/1 x 3/1 which equals 24
Answer:
81 and above
Step-by-step explanation:
They have to be 81 and above
93+69+89+97=348
348/4=87 (average)
87=81=168
168/2= 84 (average)
Answer: By lurking variable she means a variable that is not among the variables studied but which affects the response variable.
Step-by-step explanation:
The existence of a negative correlation between variables in a research work suggests that a lurking variable is present in the data, which happens to be the case with the work of this researcher.
Answer:
B
Step-by-step explanation:
CDE and CBA are similar triangles
Ratio = CE/CA = 24/48 = 1/2
CD/CB = 1/2
18/(24+x) = 1/2
24+x = 36
x = 12
DE/BA = 1/2
y/24 = 1/2
y = 12
