Draw 3 distinct lines that have the same y intercept

1 answer:

3 0

So y=mx+b
b is the y-intercept or where they cross the y-axis so just set a y-intercept and change the slope

so if y-intercept is 7
y=3x+7
y=2x+7
y=8x+7
y=-1/4x+7
and so on

Do bonds reduce the overall risk of an investment portfolio? Let x be a random variable representing annual percent return for t

rjkz [21]

Answer:

COV (all stocks) = 0.55

COV (stocks and bonds) = 0.82

Step-by-step explanation:

Coefficient of Variation is used to measure variability.

It is defined as the ration of standard deviation and the mean.

It can be used to compare variability of two population or two samples.

Formula:

$\text{Coefficient of Variation} = \displaystyle\frac{\text{Standard Deviation}}{\text{Mean}}$

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

x: 14, 0, 39, 25, 32, 27, 28, 14, 14, 15

$Mean = \frac{208}{10} = 20.8$

$Standard~Deviation = \sqrt{\frac{1169.6}{9} } = 11.39$

$Coefficient~of~Variation = \frac{11.39}{20.8} = 0.55$

y = 6, 2, 29, 17, 26, 17, 17, 2, 3, 5

$Mean = \frac{124}{10} = 12.4$

$Standard~Deviation = \sqrt{\frac{924.4}{9} } = 10.13$

$Coefficient~of~Variation = \frac{10.13}{12.4} = 0.82%$

Since coefficient of variation of x is less compared to y, thus it could be said bonds does not reduce overall risk of an investment portfolio.

Add using the number line. 8+(−4) Drag and drop the word SUM to the correct value on the number line.

Triss [41]

Answer:

Place "SUM" at 4 on the number line.

Step-by-step explanation:

8 + (-4) = 8 - 4 = 4

Adding a negative number is the same as subtracting its opposite. Adding -4 is the same as subtracting 4.

Given that y = 6 + 4x-x^2express y in the form a.-(x + b)^2, where a and b are

Y_Kistochka [10]

Answer:

6 + 4x − x² = 10 − (x − 2)²

the turning point : (2 , 10)

Step-by-step explanation:

6 + 4x − x² = − x² + 4x + 6

= − (x² − 4x) + 6

= − (x² − 4x + 4 − 4) + 6

= − [(x − 2)² − 4] + 6

= − (x − 2)² + 4 + 6

= − (x − 2)² + 10

= 10 − (x − 2)²

Then the turning point of y is (2 , 10)
