Take any number but 0 and raise it to the 0th power, and you'll get 1.
So in terms of an equation, I mean x^0 = 1 is true for any x value as long as x is nonzero.
So this means 2^0 = 1 if we replace x with 2.
Answer (b): There is a strong positive correlation between time studied and test scores.
Reason:
(1) it is upward, so it is positive.
(2) They are closely packed, so there is a strong correlation.
Area = length x width
10 X 5 = 50
Answer:
Shade above 2x + y = 4.
Shade below 2x + y = 4.
Shade above 2y = 6 – 2x.
Shade below 2y = 6 – 2x.
Make the boundary line 2x + y = 4 dashed.
