8,15,17 represents
(17)^2=289
(15)^2=225
(8)^2=64
i.e. (17)^2=(15)^2+(8)^2
By converse of Pythagoras theorem
This ∆ is a right angled ∆
Answer:
Mean
Step-by-step explanation:
The most common measures of central tendency are mode, median and mean.
The mode of the data set is the value that is repeated the most. In this case, the mode is $6 (appears twice), which does not support the raise claim of the employee.
The median is the central value of the data set. In this case, the median is also $6 (third highest value), which does not support the raise claim of the employee.
The mean of the salaries is:

Since the mean is greater than the employee's current wage, it would best support his request to be paid more.
Answer:
5 cm
Step-by-step explanation:
Here, we want to get the length of each box edge
Let the length be s
Mathematically, the volume of a cube is s^3
Thus;
s^3 = 125
s^3 = 5^3
s = 5 cm

Answer:
Step-by-step explanation:
-2x2-12x-15
Final result :
-2x2 - 12x - 15
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((0 - 2x2) - 12x) - 15
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-2x2 - 12x - 15 = -1 • (2x2 + 12x + 15)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 + 12x + 15
