Answer:
the difference in their ages is 31/2
Step-by-step explanation:
151/2=2x15+1/2=31/2
She starts out with 9,118
Gets 609 in March which brings her to 9,727
Loses 1,011 from taxes
8,716 then gets 705 which brings her to 9,421.
9,421 is greater than 9,118 by 303.
So her end balance is 303 more dollars in May then in March
The type of sampling used here is Stratified random sampling. This is used so that no contestant knows when to prepare and to test if they are actually ready for the contest.
The ex- suffix often correlates a word to mean "outside", while the in- suffix often correlates a word to mean "inside". An exterior angle of a polygon would mean "an angle outside of a polygon". An interior angle of a polygon would mean "an angle inside of a polygon". Three exterior angles of this polygon would be angle B, angle D, and angle A. This is because these angles are outside of the polygon due to the extending lines from the shape. Two interior angles of this polygon would be angle 6 and angle 8 (explanation was given when I first began answering this question). Angle 9 would be exterior since it is outside of the polygon. Two exterior angles of the polygon that are congruent are angle D and angle 9, since they are both 90 degrees (right angles).
