Find the equation to the following graph:

fiasKO [112]

First, what graph is it? It is a rational function.
What is the asymptotes? x=1

Therefore, the function is simply y=1/(x-1)

A sample of 25 undergraduates reported the following dollar amounts of entertainment expenses last year:

marin [14]

Answer:

$Range = 85$

$\sigma = 28.71$

$Interval = [666.78, 781.62]$

Step-by-step explanation:

Given

The data for 25 undergraduates

Solving (a): Range and Standard deviation

The range is:

$Range = Highest - Least$

From the dataset:

$Highest = 772$

$Least = 687$

So:

$Range = Highest - Least$

$Range = 772-687$

$Range = 85$

The standard deviation is:

$\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}$

First, calculate the mean

$\bar x = \frac{769 +691 +............+715}{25}$

$\bar x = \frac{18105}{25}$

$\bar x = 724.2$

So, the standard deviation is:

$\sigma = \sqrt{\frac{(769-724.2)^2 +(691-724.2)^2 +(699-724.2)^2 +(730-724.2)^2 +............+(715-724.2)^2}{25}}$

$\sigma = \sqrt{\frac{20604}{25}}$

$\sigma = \sqrt{824.16}$

$\sigma = 28.71$

Solving (b): The interval of the 95% of the observation.

Using the emperical rule, we have:

$Interval = [\bar x - 2*\sigma, \bar x+ 2*\sigma]$

$Interval = [724.2 - 2*28.71, 724.2 + 2*28.71]$

$Interval = [666.78, 781.62]$

A kilogram is 100,000 times greater than a centigram

Step-by-step explanation:

The table representing the relationship between grams and its sub-units is the following:

Microgram ( $\mu g$ ) = $10^{-6}$ grams (g)

Milligram (mg) = $10^{-3}$ grams (g)

Centigram (cg) = $10^{-2}$ grams (g)

Gram (g) = $10^0$ grams (g)

Kilogram (kg) = $10^3$ grams (g)

Let's now analyze the different statements given:

A microgram is 1,000 times greater than a milligram. --> FALSE. In fact, a microgram is $\frac{10^{-6}}{10^{-3}}=0.001$ times a milligram, so it is 1000 times smaller than a milligram.

A milligram is 10 times greater than a centigram. --> FALSE. In fact, a milligram is $\frac{10^{-3}}{10^{-2}}=0.1$ times a centigram, so it is 10 times smaller than a centigram.

A centigram is 100 times greater than a microgram. --> FALSE. In fact, a centigram is $\frac{10^{-2}}{10^{-6}}=10^4=10,000$ times a microgram, so it is 10,000 greater than a microgram.

A kilogram is 100,000 times greater than a centigram. --> TRUE. In fact, a kilogram is $\frac{10^3}{10^{-2}}=10^5 = 100,000$ times a centigram.
