Answer:

A) zero; cannot

Step-by-step explanation:

In line with the principle of rational expectations, expectation errors are unpredictable. The expectations of all available information will not differ from the optimal projections.The word optimal projection is inexorably intertwined with the best guess in rational expectations theory.

A line with a slope of -2 passes through the points (0,d) and (-8,9). What is the value of d?
Verizon [17]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have m = -2 and the points (0, d) and (-8, 9). Substitute:

\dfrac{9-d}{-8-0}=-2\\\\\dfrac{9-d}{-8}=-2\qquad\text{multiply both sides by (-8)}\\\\9-d=16\qquad\text{subtract 9 from both sides}\\\\-d=7\qquad\text{change the signs}\\\\\boxed{d=-7}

A book sold 35,300 copies in its first month of release. Suppose this represents 6.3 of the numbers sold to date. How many copie
skelet666 [1.2K]

Answer:

560,317.460

Step-by-step explanation:

The computation of copies that have been sold is shown below:-

we assume the number of copies is x

So, the number of copies in the first month is

= \frac{6.3}{100} x

As per the situation the number of sold copies is 35,300 so the equation will be

\frac{6.3}{100} x = 35,300

6.3x = 35,300\times 100

x = \frac{35,300\times 100}{6.3}

after solving the above equation we will get the number of copied that have been sold to date

= 560,317.460
