The answer is 30. 6, 10, and 15 all go into 30.
6x5=30
10x3=30
15x2=30
The answer is -14 degrees centigrade
The median is 7.
——————————
Arrange data in numerical order
1 3 3 6 8 10 10 15
Total number are 8, N = 8
Take the middle two numbers 6 and 8 and take their average
6+8/2 = 14/2 = 7
Therefore the median is 7.
X = 153 = 17* 9, so when <span>y = 13, x= 21*13= 273
x= 17 18 19 20 21
y= 9 10 11 12 13</span>
Answer:

Step-by-step explanation:
We want to to rewrite

Use difference of two squares to get:

This implies that:


This finally simplifies to:

Therefore the required product is
