For a monic quadratic (factor of 1 on ) we always add half the coefficient on the linear () term, so
Answer: 49/4
Answer:
x = 8; y = 5
Step-by-step explanation:
x + y = 13
x - y = 3
8 + 5 = 13
8 - 5 = 3
The coeficient is 2.6 so
2.6x+23.4
if you want to factor out the coeficient then divide the whole thing by 2.6
(2.6x+23.4)/2.6=x+9
2(x+3) means 2 times (x+3)
so the factored out coeficient is
2.6(x+9)
Answer: I got you
Step-by-step explanation: A study that is too large will waste scarce resources and could expose more participants than necessary to any related risk. Thus an appropriate determination of the sample size used in a study is a crucial step in the design of a study.
