Concerns about climate change and CO2 reduction have initiated the commercial production of blends of biodiesel (e.g., from rene

wable sources) and petrodiesel (from fossil fuel). Random samples of 47 blended fuels are tested in a lab to ascertain the bio/total carbon ratio. (a) If the true mean is .9560 with a standard deviation of 0.0080, within what interval will 99 percent of the sample means fall? (Round your answers to 4 decimal places.) The interval is from to (b) If the true mean is .9560 with a standard deviation of 0.0080, what is the sampling distribution of X¯¯¯ ? Exactly normal with μ = .9560 and σ = 0.0080. Approximately normal with μ = .9560 and σ = 0.0080. Exactly normal with μ = .9560 and σx¯= 0.0080/47−−√. Approximately normal with μ = .9560 and σx¯= 0.0080/47−−√. 1 2 3 4 (c) What theorem did you use to answer part (b)?

In synthetic division, you start by bringing down the first 1 in the box.  Multiply that by the 1 outside the box and get a 1.  Put that new 1 under the 2 inside the box and add to get 3.  Multiply the  outside the box by that 3 to get 3 and put that new 3 under the -3 in the box and add to get 0.  Multiply that 0 by the 1 outside the box to get 0.  Put that 0 under the 2 and add to get the remainder of 2.  Your answer is 2, C.

Write in the missing numbers.<br> ordering intergers
Illusion [34]

Based on the definition of integers, ordering them would depend on if they are negative, positive, or have a zero value.

<h3>How are integers ordered?</h3><h3 />

Integers are whole numbers such as 1, 15, and 55. There are no decimals and they do not come in the form of fractions.

Integers can be negative or positive. Positive integers are always higher than negative integers. For instance, 1 is more than -500,000.

If both integers are negative, the larger looking number is considered smaller. For instance, -5 is more than -55. For positive integers, this is the reverse with larger looking numbers being larger.

An example of the correct order of intergers based on this dataset (1, 52, -800, 86, 5, and -4) is:

= -800, -4, 1, 5, 52, 86
