Answer:
Mean = Mean is all of the numbers added up and divided by the amount of numbers you have added up. Therefore its 414 ÷ 15 = 27.6
Mode = Most common number = 35
Range = Largest number - Smallest number
40 - 5 = 35
Median = 32 (Middle number)
Answer:
Tanya is 20 years old
Step-by-step explanation:
Let the age of Vera = x years
The age of Linda is twice the age of Vera = 2x years
Tanya is four less than four times the age of Linda = 4(2x)-4 = 8x-4
Total age of Vera, Linda and Tanya is:
x+2x+8x-4
Combine the like terms:
11x-4
But now their total age is two more than nine times the age of Vera:
11x-4 = 9x+2
Solve the expression
Combine the like terms:
11x-9x=2+4
2x=6
Divide both the sides by 2
2x/2 = 6/2
x= 3
Thus the age of Vera is 3 years.
The age of Linda is 2x= 2*3 = 6 years
The age of Tanya is 8x-4 = 8*3 - 4 = 24-4 = 20years....
Answer:
1) (2,2)
2) (2,-1)
3) (-4,1)
Step-by-step explanation:
Each subtraction expression, in relation with the Pythagoras Theorem, represents the length of one side of a right-angled triangle with a hypotenuse of length d.
What is Pythagoras Theorem?
The Pythagoras Theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the remaining two sides in a right-angled triangle.
The formula for Pythagoras Theorem is given by,
Here, h is the hypotenuse, a and b are the two legs of the right-angled triangle.
Each Subtraction in view of Pythagoras Theorem
It is is given that,
or 
Therefore, d is the hypotenuse and each subtraction term represents one leg of the right-angled triangle in accordance with the Pythagoras Theorem.

12% of 4,000 = 480
4,000 * 3 = 12,000
480 * 3 = 1,440
12,000 + 1,440 = 13,440
So...at the end of 3 years, $13,400 is due.
Hope I helped! Please mark Brainliest if correct; I would greatly appreciate it. :)
