If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse
Answer:
4
Step-by-step explanation:
pythagoras theorem = a* + b* = c* ( by '*' i mean squared)

Answer: D
Step-by-step explanation:
Mean is the average of all numbers, and spread is the range of the data set.
Mean:
2+3+4+4+7=20
20/5=4
The mean is 4.
Spread:
Minimum 2
Maximum 7
7-2=5
The spread is 5.
Either way, even if you didn't know what the center was, spread has 4 different options meaning you can just solve for spread if needed. Just a heads up!
