Answer:

$\sf p = \dfrac{i}{rt}$

Step-by-step explanation:

Solve for p:

$\longrightarrow$ i = prt

i = prt is equivalent to prt = i:

$\longrightarrow$ prt = i

Divide both sides by rt:

$\longrightarrow$ $\sf \dfrac{prt}{rt} = \dfrac{i}{rt}$

$\sf \dfrac{prt}{rt} = p:$

$\longrightarrow$ $\sf p = \dfrac{i}{rt}$

What’s the difference between a bar chart and a histogram

timama [110]

Answer:

Bar charts are for discrere data. That is, can only take particular values, eg number of children, which can only take a whole number, or favourite football team for instance. They typically have gaps between the bars to indicate the separateness of each value.

Histograms are either continuous (height) or grouped discrete data and don’t have gaps between the bars. Also, with Histograms, since the width of each bar is not necessarily the same, the area of the bar and not its height indicates the frequency

What effect does the "a" value have on the function f(x)=log(x)

Leni [432]

I would guess they're referring to some general form firstf(x)=alog(x−h)+kWhere 'h' represents horizontal shifts, 'k' vertical shifts and 'a' stretches the function. "a" will also reflect the function across the x-axis if the value is negative. But NOT across the y-axis. I hope that's the place they wanted to put the a at least

5. Juliette works at a department store and earns $11.20 per hour. Last week she worked 32 hours.

tatuchka [14]

$358.40
Gross pay is the amount of money you earn before taxes. So you just have to multiply $11.20 by 32 to get your answer

Costs for standard veterinary services at a local animal hospital follow a Normal distribution with a mean of $72 and a standard

Romashka [77]

Answer:

$P(32$

And we can find this probability with this difference:

$P(-1.905$

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.

$P(-1.905$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the costs of services of a population, and for this case we know the distribution for X is given by:

$X \sim N(72,21)$
