Answer:

$\frac{\pi }{6}$

Step-by-step explanation:

$\frac{7\pi }{6}$ is in the third quadrant

To find the reference angle subtract π from it, that is

reference angle = $\frac{7\pi }{6}$ - π = $\frac{\pi }{6}$

find four solutions for the following linear equations your answer must include at least two positive numbers for X and at least

sattari [20]

9514 1404 393

Answer:

(-18, 14), (-9, 9), (9, -1), (18, -6)

Step-by-step explanation:

Since there is a 9 in the denominator of the coefficient of x, we will get integer solutions only if x is a multiple of 9. Suitable values meeting the problem requirements are x ∈ {-18, -9, 9, 18}. Then the corresponding values of y are ...

y = -5/9(-18) +4 = 10 +4 = 14

y = -5/9(-9) +4 = 5 +4 = 9

y = -5/9(9) +4 = -5 +4 = -1

y = -5/9(18) +4 = -10 +4 = -6

The four solutions we have found are ...

(-18, 14), (-9, 9), (9, -1), (18, -6)

The following list contains the average annual total returns (in percentage points) for 9 mutual funds. The mutual funds appear

VladimirAG [237]

Answer:

Mean =25.78

Median =20

Step-by-step explanation:

given that the following list contains the average annual total returns (in percentage points) for 9 mutual funds. The mutual funds appear in an online brokerage firm's "all-star" list.

40, 30, 6, 10, 30, 18, 15, 20, 36

Let us find the sum of these 9 entries

Sum = 205

a) Mean = $\frac{205}{9} =22.78$

b) Median of this data set is the middle entry after arranging in ascending order

Here it would be the 5th entry

6,10, 15, 18,20, 30, 30, 36, 40

Median = 20

If the discriminant of a quadratic equation is equal to -8 , which statement describes the roots?

GaryK [48]

Answer: There are no real number roots (the two roots are complex or imaginary)

The discriminant D = b^2 - 4ac tells us the nature of the roots for any quadratic in the form ax^2+bx+c = 0

There are three cases

If D < 0, then there are no real number roots and the roots are complex numbers.
If D = 0, then we have one real number root. The root is repeated twice so it's considered a double root. This root is rational if a,b,c are rational.
If D > 0, then we get two different real number roots. Each root is rational if D is a perfect square and a,b,c are rational.

The length of the side of a regular octagon is 2.5y - 3 units. The perimeter of the octagon is _

lidiya [134]

Answer:

Step-by-step explanation:

1 side = 2.5y - 3

8 sides = 8(2.5y - 3)

8 sides = 20y - 24

Perimeter = 20y - 24
