The surface area of a piece of paper is 137 cm2. Use the fact that 10 mm = 1 cm to convert this area to mm2. Give your answer as

irakobra [83]

<h3>The surface area of a piece of paper is $13700\ mm^2$ </h3>

Solution:

surface area of a piece of paper = 137 sq cm

Use the fact that 10 mm = 1 cm to convert this area to mm^2

$1\ cm = 10\ mm$

Then,

$1\ cm^2 = 100\ mm^2$

Convert 137 sq cm to sq mm

$137\ cm^2 = 137 \times 100\ mm^2\\\\137\ cm^2 = 13700\ mm^2$

Thus, surface area of a piece of paper is $13700\ mm^2$

Which expression is equivalent to –5(6x – 3) – 4(–2x + 1) + 3(4x) – 8?

Sedaia [141]

Answer:

C = -10x+3

Step-by-step explanation:

So the simplified version of the main expression is -10x+3. after finding the main expression you just need to simplify the rest of them too.

A. = -10x+9

B. = 8x-9

C. = -10x+3

D. = -10x-3

Now that you simplified all the expressions, you can pick out the one that's the same as the target expression, which is C.

An analyst for a large credit card company is going to conduct a survey of customers to examine their household characteristics.

zheka24 [161]

Answer:

We can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.

Step-by-step explanation:

Previous concepts

A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation

A parameter is "any numerical quantity that characterizes a given population or some aspect of it".

Solution to the problem

For this case the analyst knows that from previous records that the mean for all the customers (that represent the population of interest) is $\mu = 1622$

He have a random sample of n =500 customers from the previous month and he knows that 1732 represent the sample mean for the selected customers calculated from the following formula:

$\bar X = \frac{\sum_{i=1}^{500} X_i}{500}= 1732$

So on this case we can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.
