You are paying 15% of the original price because

50% + 35% = 85%

100% - 85% = 15%

I hope this helped :) :)

The unchanging value of the ratio between two proportional quantities?

Naddika [18.5K]

The right answer is the constant of proportionality

If two variables are related and this relationship is that there is a constant ratio between them, then we are talking about proportionality. There are two types of proportionality.

1) Direct Proportionality:

In a mathematical language this is given by this equation:

$y=kx$

where $k$ is in fact this constant of proportionality. If $x$ increases, $y$ also increases at the same rate. On the other hand, If $x$ decreases, $y$ also decreases at the same rate.

2) Inverse Proportionality:

In a mathematical language this is given by this equation:

$y=\frac{k}{x}$

where $k$ is also called the constant of proportionality. If $x$ increases, $y$ decreases at the same rate. On the other hand, If $x$ decreases, $y$ increases at the same rate.

A recent survey of 50 executives who were laid off during a recent recession revealed it took a mean of 26 weeks for them to fin

drek231 [11]

Answer:

The pvalue of 0.0113 < 0.05 means that there is sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance

Step-by-step explanation:

The null hypothesis is:

$H_{0} = 28$

The alternate hypotesis is:

$H_{1} < 28$

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

A recent survey of 50 executives who were laid off during a recent recession revealed it took a mean of 26 weeks for them to find another position.

This means that $n = 50, X = 26$

Assume the population standard deviation is 6.2 weeks.

This means that $\sigma = 6.2$

Does the data provide sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance

We have to find the pvalue of Z, looking at the z-table, when $\mu = 28$ . It if is lower than 0.05, it provides evidence.

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{26 - 28}{\frac{6.2}{\sqrt{50}}}$

$z = -2.28$

$z = -2.28$ has a pvalue of 0.0113 < 0.05.

The pvalue of 0.0113 < 0.05 means that there is sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance

Cscθ - sinθ = _____

galina1969 [7]

So you maybe know that $\csc x = \frac{1}{\sin x}$ . Now let us try to simplify the expression

$\csc x - \sin x = \frac{1}{\sin x} - \sin x = \frac{1}{\sin x} - \frac{\sin^2 x }{\sin x}=\frac{1-\sin^2 x}{\sin x} =$

$= \frac{\cos^2 x}{\sin x} = \cot x \cdot \cos x$
