Lower quartile=25% of total frequency/numbers in the data set
Median=50% of total frequency/numbers in the data set
Upper quartile=75% of total frequency/numbers in the data set
Hope this helps:)
-7.8
The rest can be solved as rational. Negative numbers are not rational.
The answer in simplest form would be 5/6
$3, $1, $5, $2, $3, $9, $1 = $24 - $1 = $23 - $1 = $22.
$22 is the estimation of the bill when all of the amounts are rounded to the nearest dollar. The estimation is greater than the total bill which is 23 cents less than the estimation. The total on the register is reasonable and accurate.

Answer:
(-2, 1)
Step-by-step explanation:
Rotating a point 180° about the origin in either direction is equivalent to reflecting it across the origin. The effect is to negate both coordinates.
(x, y) ⇒ (-x, -y) . . . . . rotation 180°
(2, -1) ⇒ (-2, 1) . . . . . P' rotated 180° from P
The coordinates of the rotated point are (-2, 1).
