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:
Step-by-step explanation:
When working with 45-45-90 triangles the hypotenuse is the same as the other legs multiplied by root 2. Therefore if you need to find the legs and already have the hypotenuse, divide the hypotenuse by root 2.
10/ sqrt(2) = 7.1 is the rounded answer.
to double check your work just multiply 7.1 by the square root of 2 and you'll get <em>close</em> to 10. (because the answer is rounded and not exact.)

Answer:
-3
Step-by-step explanation:
x + (x+1) +(x+2)+(x+3)+(x+4)+(x+5)+(x+6) = 0
7x + 21 = 0
x = -3
