Answer:
9.13385827
Step-by-step explanation:
The answer is D because the median is 4, the mean is 4, and the range is 4
Answer:
x1 = 1, x2 = 2, x3 = 7
Step-by-step explanation:
(x-2) x (x² -8x + 7) = 0
When the product of factors equals , at least one factor is 0.
x-2=0
x² -8 + 7=0
Solve the equation for X.
x-2=0
x=2
x² -8+7=0
x=7
x=1
The final solutions are
x1 = 1, x2= 2, x3=7
the pythagorean theorem is a^2+b^2=c^2
You have a and c already, so its 5^2+b^2=13^2
13^2 equals 169. 5^2 equals 25.
You now have 25+b^2=169
169-25=144
The square root of 144 is 12.
The other leg is 12 units
