60 more students voted for Kevin

Step-by-step explanation:

Given

total students = 300

Voted for Jennifer = 40%

Voted for Kevin = 60%

We will find number of students for one of them and then will subtract from total to find the others.

So,

Students who voted for Jennifer:

$= 40\%\ of\ 300\\=0.40*300\\=120\ students$

Students who voted for Kevin

= $=Total\ students-Students\ who\ voted\ for\ Jennifer\\=300-120\\=180\ students$

In order to calculate that how many more students voted for Kevin :

180-120 = 60

Hence,

60 more students voted for Kevin

Standard deviation measures _____ risk while beta measures _____ risk.

Stolb23 [73]

Answer:

Standard deviation measures Total risk while beta measures Systematic risk.

Step-by-step explanation:

The total risk is the total variability of the portfolio and includes the systematic risk and the unique risk.

The systematic risk is measured by the beta coefficient and it considers the no diversified risk such as changes in the global market. Unique risks are the ones that result from factors specifically related to the company.

The half-life of the given exponential function is of 346.57 years.

<h3>What is the half-life of an exponential function?</h3>

It is the value of t when A(t) = 0.5A(0).

In this problem, the equation is:

$A(t) = A(0)e^{-0.002t}$ .

In which t is measured in years.

Hence the half-life is found as follows:

$0.5A(0) = A(0)e^{-0.002t}$

$e^{-0.002t} = 0.5$

$\ln{e^{-0.002t}} = \ln{0.5}$

$0.002t = -\ln{0.5}$

$t = -\frac{\ln{0.5}}{0.002}$

t = 346.57 years.
