Answer:
First, you will need to arrange the data in an ascending order and the median is the middle value.
If the number of values is an even number, the median will be the average of the two middle numbers.
2, 6, 7, 10, 11, 15, 15
The median in this set is <em><u>10</u></em>.

Answer:
2
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
, then
= 
= 
×
= 2
X-2=10
or
10=x-2
this is because it says "2 less than a number is 10" so we can infer that 2 is less than a number (x) so knowing that less than means subtract x-2=10 or you can put it as 10=x-2
Answer:
Step-by-step explanation:
hello :
the system is : y= 3x+4....(*)
y+6=3x....(**)
by (**) : y = 3x - 6
so : y= 3x+4
y= 3x - 6
means : 3x+4 = 3x - 6
4= -6.......(false)
conclusion : no reals solutions
Answer:
y=-1/3x-1
Step-by-step explanation:
Perpendicular lines have slope that are opposite sign and reciprocals
3x-y=12 has a slope of 3, therefore perpendicular line must have slope of -1/3
2=-9(-1/3)+b
2=3+b
b=-1
