The “convenience” sample is the most likely to be a biased set because anything that is chosen out of convenience for the experimenter/observer will be of preference tendency.
A. No. of oranges in layer no. i = i*i
b. No oranges reqired for 10 layers = ∑i² where i=0 and i-->10
= 385
Answer:
B
Step-by-step explanation:
The diagram basically shows three angles that make up a straight line.
We know the angle of a straight line is 180°.
Since there are three angles, Angle 1, Angle 2, and Angle 3 that make up a straight line, we can write:
Angle 1 + Angle 2 + Angle 3 = 180
3x + 4x + 2x = 180
9x = 180
x = 180/9
x = 20
The correct answer is B

Answer: C) 2</h3>
The term 2 is really the same as 2*1 = 2x^0. Recall that anything (except 0) to the zeroth power is 1. So the rule is x^0 = 1 when x is nonzero.
Looking at 2x^0, we see that 2 is the coefficient here because it is the constant being multiplied with the variable term.
