If you divide 16 by 2 you get 8, so, 8 teams payed $50, while the other half payed $60.

Hope this helps. ^_^

(If you're gonna add them up it's 8x60=480 + 8x50=400=880) :P

The relationship between x and y is represent as:

Since, the relationship is linear.

The standard form of equation of line is:

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Consider any two set x and y values from the given relationship.

Let (-2, 10) and (-1,7.5)

$\text{Substitute x}_1=-2,y_1=10,x_2=-1,y_2=7.5\text{ in the standard equation of line.}$

$\begin{gathered} y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1) \\ y-10=\frac{7.5-10}{-1-(-2)}(x-(-2)) \\ y-10=\frac{-2.5}{1}(x+2) \\ y-10=-2.5(x+2) \\ y=-2.5(x+2)+10 \end{gathered}$

The equation of the linear relationship between x and y is:

y = -2.5(x + 2) + 10

Now, to check that the point (9, -17.5) lies on the represented relationship between x and y

Substitute x = 9 and y = -17.5 in the equation y = -2.5(x + 2) + 10

y = -2.5(x + 2) + 10

-17.5 = -2.5(9 + 2) + 10

-17.5 = -2.5(11) + 10

-17.5 = -27.5 + 10

-17.5 = -17.5

Thus, LHS = RHS

Hence the point (9, -17.5) lie on the given linear relationship between x and y.

Answer: The point (9, -17.5) lie on the given linear relationship between x and y.

5-year Treasury bonds yield 5%. The inflation premium (IP) is 1.9%, and the maturity risk premium (MRP) on 5-year bonds is 0.4%.

Eddi Din [679]

Answer:

real risk-free rate = 2.7 %

Step-by-step explanation:

Given data

Treasury bonds yield r = 5%

time = 5 year

(IP) = 1.9%

MRP = 0.4%

to find out

real risk-free rate r*

solution

we will find real risk-free rate r* by the given formula that is

Treasury bonds yield = real risk-free rate + IP + MRP + default risk premium + liquidity premium

so here default risk premium and liquidity premium both are zero

put all the other value we get real risk-free rate

real risk-free rate = 5% - 1.9 % - 0.4%

real risk-free rate = 2.7 %
