Answer:
C. The square root of a number, positive or negative, is always positive. However, the cube of a negative number is negative.
Step-by-step explanation:
Of the choices offered, the one shown above is the only one that remotely makes any sense. Its description of square roots is erroneous, however.
The square root of a number n is the solution to the equation ...
x² = n
The function f(x) = x² has a range that only includes non-negative numbers, so the square root of a negative number does not exist. (Your answer choice says it is positive. It is actually non-existent among real numbers.)
On the other hand, the cube root of a number n is the solution to the equation ...
x³ = n
Since f(x) = x³ has a range that includes all real numbers, the cube root of n exists for all real numbers. (It is negative for negative values of n.)

The answer wording would be correct if the word "root" were left out.
Answer:
None.
Step-by-step explanation:
let's check it
- 2a + 2a + 7 = 8
7≠ 8
So there's no solution for the given equation.

The frequency would be 60%.
You know how many times she rolled the dice (100) then it also tells you the dice rolled 6 40 times. So then we minus 100 by 4. Which will end up getting us 60. Which we can also write as 60%. So the frequency is 60%.
Answer:
AB=13
Step-by-step explanation:
Given: BC= 14, AC=27
since AC is the whole line, you subtract by BC to solve AB so,
27-14=13
