↝ Form into 
where a > 0 (Optional)
↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula
↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝
Therefore, the answer for Complex Number System is (5±√7i)/2
Answer:
x = 2
Step-by-step explanation:
Given
3x + 8x - 2 = 20 , that is
11x - 2 = 20 ( add 2 to both sides )
11x = 22 ( divide both sides by 11 )
x = 2
I believe the answer is B
Answer: (20.86, 22.52)
Step-by-step explanation:
Formula to find the confidence interval for population mean :-
, where 
= sample mean.
z*= critical z-value
n= sample size.
= Population standard deviation.
By considering the given question , we have
n= 58
Using z-table, the critical z-value for 95% confidence = z* = 1.96
Then, 95% confidence interval for the amount of time spent on administrative issues will be :
Hence, the 95% confidence interval for the amount of time spent on administrative issues = (20.86, 22.52)
Answer:
4. D
5. B
6. B
Step-by-step explanation:
Flowcharts are used to show the steps of a process in a subsequential order. They are not used to represent relations or functions therefore the answer is D
In a function each x value had its own corresponding y value. To be more specific the x value cannot repeat.
In answer choice A the x value 3 and -3 repeats therefore is is not a function
in answer choice b each x value has it's own y value. So this might be the answer but just to be safe let's check the other
In answer choice C the x value 2 repeats multiple times therefore it is not a function
In answer choice D the x value 4 repeats therefore it is not a function
So we can conclude that the answer is B
The dependent variable is the variable the depends on another variable to get it's value. in the description of the question it says that the number of products on his plastic bag lists INFLUENCES how many plastic bags he brings to the store.This means that the number of plastic bags depends on the number of products on the plastic bags lists. Hence the answer is B
