Answer:
the mean is 5
Step-by-step explanation:
because if you add all the numbers and divide by the number of digits you should get the equation 40/8= 5 and that´s the answer
Step-by-step explanation:
Answer:
3 < x < 27
Step-by-step explanation:
We can't tell what "must ne greater" means, so we'll tell you the limits on the side length and you can choose the one that is relevant.
The third side of a triangle must have a length that lies between the difference and sum of the two lengths you know.
15 -12 = 3
15 +12 = 27
The value of x must be between 3 and 27:
3 < x < 27
__
If you allow the triangle to have zero area, then x can be 3 or 27. Many authors claim such a "triangle" is not allowed, so don't allow those cases.
64 = 2 ^6
16 = 2^4 =
2^ 6*(2x+4) = 2^4 * 5x
6(2x+4) = 20x
10/3 x = 2x +4
4/3 x = 4
x = 3
you can also use logarithms like so
(2x+4)ln64 = 5x ln16
ln64/ln16 = 3/2
3/2 * 2x + 3/2 * 4 = 5x
3x + 6 = 5x
2x = 6
x = 3
Use the Pythagorean theorem: a² + b² = c²
c = hypotenuse (which means) = 53
a and b are equal to the side length
So a = 21.
Use the formula and solve.
21² + b² = 53²
441 + b² = 2809
b² = 2368
b = 48.66210024238575 or 8√37
