Answer:
Dispersion
Step-by-step explanation:
Given a set of scores {a1, a2, ..., an} ordered in value, the range can be described as the difference between the highest and the lowest value. We can write it as:
range = an - a1
Thus, the range provides information about the dispersion of our set of values. A high range means that the highest and the lowest value are highly separated, on the other hand, a low range mean that there is a little difference between those values.
This is usually used to measure dispersion on a set of values, together with standard deviation and interquantile range. However, we cannot maintain that one is better than the others.
Answer:
-6i
Step-by-step explanation:
Complex roots always come in pairs, and those pairs are made up of a positive and a negative version. If 6i is a root, then its negative value, -6i, is also a root.
If you want to know the reasoning, it's along these lines: to even get a complex/imaginary root, we take the square root of a negative value. When you take the square root of any value, your answer is always "plus or minus" whatever the value is. The same thing holds for complex roots. In this case, the polynomial function likely factored to f(x) = (x+8)(x-1)(x^2+36). To solve that equation, you set every factor equal to zero and solve for the x's.
x + 8 = 0
x = -8
x - 1 = 0
x = 1
x^2 + 36 = 0
x^2 = -36 ... take the square root of both sides to get x alone
x = √-36 ... square root of an imaginary number produces the usual square root and an "i"
x = ±6i
For this case we have the following number:
2.25 x 10-4
We observe that it is written in exponential notation.
The exponent is negative, therefore, we must move the point to the left.
We have then:
2.25 x 10-4 = 0.000225
Answer:
0.000225
Answer:
A = 173 m²
Step-by-step explanation:
P = 60m = 3L => L = 60 : 3 = 20 m
A = L×h/2 = 20m×17.3m/2 = 10m×17.3m = 173 m²
30% is needed because i believe it is i am really trying hope u get it right <span />
