denis-greek [22]

Answer:

<em>Average rate of change is </em><em>-78.</em>

Step-by-step explanation:

A talent competition on television had five elimination rounds. After each elimination, only one-third of the contestants were sent to the next round.

The table that shows the number of contestants in each round of the competition is,

x     f(x)

1      243

2     81

3     27

4     9

5     3

Average rate of change is the change in the y-value divided by the change in the x-value for two points on the graph.

i.e \dfrac{f(x_2)-f(x_1)}{x_2-x_1}

So, the average rate of change of f(x) from x = 1 to x = 4 is,

=\dfrac{f(4)-f(1)}{4-1}

=\dfrac{9-243}{4-1}

=\dfrac{-234}{3}

=-78

Since f(x) is decreasing, so rate of change is negative.

SVEN [57.7K]

Step-by-step explanation:

First, we may wonder, what does the term <em>margin of error</em> mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.

It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to<em> increase the sample size</em> of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.

Jaidee spent half of her weekly allowance on clothes. To earn more money her parents let her wash a dog for $9. What is her week
dolphi86 [110]

Answer:

14

Step-by-step explanation:

Firstly, we need to subtract the amount she earned from walking the dog ($9.00) from the end total ($16.00). This leaves us with $7.00.

Since she spent exactly<em> </em><em>half</em> of her weekly allowance, we must multiply the remaining $7.00 by 2. This leaves us with our final answer of $14.00.
