Answer:
The equation is [tex]x^{2} +2\cdot x + 2 = 0[/tex]-
Step-by-step explanation:
According to the statement, we have a second order polynomial of the form [tex]A\cdot x^{2}+ B\cdot x + C = 0[/tex], whose solutions can be found by Quadratic Formula:
[tex]x_{1,2} = \frac{-B\pm \sqrt{B^{2}-4\cdot A\cdot C}}{2\cdot A}[/tex] (1)
Where [tex]A[/tex], [tex]B[/tex] and [tex]C[/tex] are the coefficients of the polynomial.
If roots are conjugated complex numbers, then:
[tex]B^{2}-4\cdot A\cdot C < 0[/tex] (2)
[tex]B^{2} < 4\cdot A \cdot C[/tex]
If we know that [tex]A = 1[/tex], [tex]C = 2[/tex] and [tex]x_{1,2} = -1\pm i[/tex], then we find that:
[tex]-1\pm i = -\frac{B}{2}\pm \frac{\sqrt{B^{2}-8}}{2}[/tex]
[tex]-2 \pm i\,2 = -B \pm \sqrt{B^{2}-8}[/tex]
By comparing each side, we have the following system of equations:
[tex]-B = -2[/tex] (3)
[tex]\sqrt{B^{2}-8} = 2[/tex] (4)
Whose solution is [tex]B = 2[/tex].
In a nutshell, the equation is [tex]x^{2} +2\cdot x + 2 = 0[/tex]-

Classify the hypothesis test as two-tailed, left-tailed, or right-tailed.
At one school, the average amount of time that tenth-graders spend watching television each week is hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased from the previous mean of 21.6 hours.
a. Two-tailed
b. Right-tailed
c. Left-tailed
Answers
Answer:
C: left tailed
Step-by-step explanation:
In two tailed hypothesis, the alternative hypothesis is when mean can either be lesser or greater than the given value. Usually uses the symbol ≠.
In right tailed, the alternative hypothesis is when the mean is greater than the given value.
In left tailed, the alternative hypothesis is when the mean is lesser than the given value.
In this question, the hypothesis test to be performed is to determine if the average amount of time spent watching television per week has decreased from the given value of 21.6 hours.
Thus, it is left tailed test.

Sue needs to drive 372 miles to visit her aunt. She stopped at a gas station one-third of the way in to her trip. How many miles has she traveled?
Answers
Answer:
Sue has traveled 124 miles.
Step-by-step explanation:
Here, the distance covered by Sue is a fraction of the total distance to be covered.
The total distance to her aunt's = 372 miles
but the gas station is at one-third of the distance to be covered.
Thus,
Miles traveled by Sue = [tex]\frac{1}{3}[/tex] x 372
= 124
Miles traveled by Sue = 124 miles.
Therefore Sue has traveled 124 miles.
