You actually can’t get the exact square root of a negative number, it is not 3 as 3 squared is 9 not negative 9. It is not possible to square a number to get a negative answer, that’s where all the “i” stuff comes in with irrational numbers.
Answer:a
Step-by-step explanation:
We are tasked to solve for the median of the doctor's patients during the last 7 days that he was on duty. The given numbers are the following:
24, 27, 31, 19, 26, 15 and 19
Solving for the median, we have:
Median = (24 + 27 + 31 + 19 + 26 + 15 + 19) / 7 days
Median = 23
The median is 23.
Answer:
x = - 5
Step-by-step explanation:
x = - 2 is the equation of a vertical line parallel to the y- axis.
A parallel line must also be vertical with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 5, 4) with x- coordinate - 5, thus
x = - 5 ← equation of parallel line
