Answer:
D. A square because it has 4 right angles.
Step-by-step explanation:
A square is a rectangle but a rectangle is not a square.
6x - 10(x + 12) = -4x - 24
<em><u>Distributive property.</u></em>
6x - 10x - 120 = -4x - 24
<em><u>Add 10x to both sides.</u></em>
6x - 120 = 6x - 24
<em><u>Cancel like terms.</u></em>
<em>Add 24 to both sides.</em>
-96 ≠ 0.
This equation is incorrect, as -96 will never be equal to 0.
Use point (-3,2):
2 = 4*(-3) + b
b = 2 +12
b = 14
The equation is y = 4x + 14

Answer:
Mean =13, Median=9, Mode =7, Range=43
Step-by-step explanation:

(1)Mean


<u>Median</u>
First we arrange the sales in ascending order
7,7,7,8,9,9,10,11,12,50
Since there are two terms in the middle, the Median =(9+9)/2 =9
<u>Mode</u>
The mode is the number of sales with the highest frequency.
Mode =7
<u>Range</u>
Range =Highest Value - Lowest value =50-7=43
(b)Mean =13, Median=9, Mode =7, Range=43
The Median seems to best represent the ten numbers. this is as a result of the fact that the value of the Mean and range were affected by the outlier number(50).
The School should therefore order T-Shirts in the range of the Median.
