Answer:

x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11

Step-by-step explanation:

This polynomial is a quadratic. Its coefficients are a = 1, b = 1 and c = 3.

Thus, the discriminant b^2-4ac is 1^2 - 4(1)(3), or 1 - 12, or -11.

Because the discriminant is negative, the roots are complex.

The roots are:

-1 ±√(-11) -1 ±i√11

x = --------------- = ----------------, so x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11

A manufacturer of new light bulbs claims the average lifetime of its long-life bulb is more than 4000 hours. To test this claim,

natka813 [3]

Answer: C. 12.5

Step-by-step explanation:

Given : A manufacturer of new light bulbs claims the average lifetime of its long-life bulb is more than 4000 hours.

Population mean : $\mu=4000$

Sample size : n= 100

Sample mean : $\overline[x}=4500$

Standard deviation: $s=400$

The value of test-statistic is given by :-

$z=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}\\\\\Rightarrow\ z=\dfrac{4500-4000}{\dfrac{400}{\sqrt{100}}}\\\\\Rightarrow\ z= 12.5$

Hence, the value of the test statistic for this problem is 12.5.

Answer:

A: 5% High risk; 15% medium risk; 80% low risk.

Step-by-step explanation:

Option A will be the most appropriate because it follows the risk pyramid pattern that guides investors.

Now, in the risk pyramid, the low risk investment should be the biggest and should contain a large part of your assets since it will be low in risk and have good foreseeable returns. The medium risk investment should be the next biggest as it allows stable returns while capital appreciates. While the high risk return investment should be the lowest as it should consist of money you can lose and wouldn't really affect you.

During two years, the population of birds of an island became 7 times more than before. If the first year increase in the popula

9966 [12]

The percent increase of the second year was 85.71%

Step-by-step explanation:

The exponential growth formula is y=a(1+r)^x

where;

y=population after x years

a=original population

r=growth rate as a decimal

x=number of time interval that have passed

Let starting population be p

The first year increase in the population was 40% this means;

r=0.4 , x=1 and a=p thus the equation will be

y=p(1+0.4)^1 ⇒⇒y=1.4 p

In the second year the population of birds of an island became 7 times more than before which is 7p

7p= 7*1.4p= 9.8p

Increase will be;

9.8p-1.4p=8.4

% increase will be;

8.4/9.8 *100 =85.71%
