When doing blood testing for a viral infection, the procedure can be made more efficient and less expensive by combining partial

Serjik [45]

Answer:

0.1694 = 16.94% probability of a positive result for three samples combined into one mixture.

Step-by-step explanation:

For each test, there are only two possible outcomes. Either it is positive, or it is negative. The probability of a test being positive or negative is independent of any other test, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The probability of an individual blood sample testing positive for the virus is 0.06.

This means that $p = 0.06$

If samples from three people are combined and the mixture tests negative, we know that all three individual samples are negative. Find the probability of a positive result for three samples combined into one mixture.

It will be positive if at least one of the tests is positive, that is:

$P(X \geq 1) = 1 - P(X = 0)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{3,0}.(0.06)^{0}.(0.94)^{3} = 0.8306$

Then

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8306 = 0.1694$

0.1694 = 16.94% probability of a positive result for three samples combined into one mixture.

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. Thepizza cost $12.00. They spend

tatiyna

It should cost $1.65 for each large drink.

You subtract $12 to $16.95 and that would give you 4.95 and divide it to the number of drinks they bought which is 3 and that would give you $1.65

If a company issues bonus shares, what is the most likely effect on its debt-equity ratio?

Lena [83]

Answer:

If a company issues bonus shares, there will be no increase in the capital and the debt-equity ratio remains unchanged.

Step-by-step explanation:

Free additional shares offered to existing shareholders is known as a bonus issue.

Bonus issues are given to shareholders when companies are short of cash and shareholders expect a regular income. It may also be issued to restructure company reserves.

However, issuing bonus shares does not involve cash flow. It increases the company’s share capital but not its net assets.

Since bonus issues only increase the number of shares a shareholder is holding but not the ratio/percentage of holding. Thus, if a company issues bonus shares, there will be no increase in the capital and the debt-equity ratio remains unchanged.
