Mathematics

neonofarm [45]3 years ago

Answer:


Step-by-step explanation:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Answer:

y-value at intercept = f(0), the value of the function when x = 0

Step-by-step explanation:

The "y-intercept" of a graph (any graph, not just a straight line) is the y-value obtained when x = 0.  In other words, the y-intercept is the point at which the graph crosses the y-axis (whose equation is x = 0).  Very often the y-intercept represents the initial (beginning) value of functions whose domains include [0, +infinity).

If the standard deviation of returns on the market is 20 percent, and the beta of a well-diversified portfolio is 1.5. Calculate
Luden [163]

Answer:

a. 30 percent.

Step-by-step explanation:

Given that:

The standard deviation of returns = 20 percent

Beta = 1.5

Beta=Standard deviation of portfolio × correlation/Standard deviation of market × Correlation

Since Correlation with the market will be +1;

Then;

The Standard deviation of portfolio = 1.5 × 20%

The Standard deviation of portfolio = 30.00%

KatRina [158]
20 bicycles each of 2 wheels
So 20 x 2 = 40 wheels

10 cars each of 4 wheels
So 10 x 4 = 40 wheels

Total = 40 + 40
= 80 wheels
