Answer:
the domain is always all real numbers and you find the range by finding the vertex which is f(-b/2a)
Step-by-step explanation:
Answer:
1-P(z less than or equal to 1.4)
Step-by-step explanation:
To know what sentence is equivalent to the expression P(z ≥ 1.4), we just need to know the translation of the symbol '≥'
This symbol means that the expression in the left side is greater than or equal to the expression in the right side, so we can translate this symbol as 'greater than or equal to'.
As P means a probability, we can also shift the symbol from 'greater than or equal to' to 'less than or equal to' if we make 1 minus the probability, so the expression P(z ≥ 1.4) is equivalent to 1 - P(z ≤ 1.4), and this second expression can be translated as 1-P(z less than or equal to 1.4)
The distance is given by:
A. This is correct. When you transfer n to the other side, that would be the reciprocal power of a.
b. This is incorrect, because this contradicts with choice a.
c. This is correct. When a number is raised to a "1/n" fraction, that is equivalent to the nth root of the number.
d. This is incorrect, because it is not equivalent to the given equation.
<em>Thus, the answers are A and C.</em>
