\dfrac{25099.506}{4.45} \ \text{Divide} 

<span>Shift the decimal points of both 25099.506 and 4.45 to the right by 2 decimal places. 
</span>
<span>(This is needed to convert 4.45 to 445, since long division must divide by a whole number.) 
</span>
\text{Set up the long division.}&#10;

\text{Calculate 2509 divided by 445, which is 5 with a remainder of 284.}
<span>
</span>\text{ Bring down 9, so that 2849 is large enough to be divided by 445.}

\text{Calculate 2849 divided by 445, which is 6 with a remainder of 179.} &#10;

\text{Bring down 5, so that 1795 is large enough to be divided by 445.}

\text{Calculate 1795 divided by 445, which is 4 with a remainder of 15.}

\text{Bring down 06, so that 1506 is large enough to be divided by 445.&#10;}

\text{Calculate 1506 divided by 445, which is 3 with a remainder of 171.}

\text{Bring down 0, so that 1710 is large enough to be divided by 445.}

\text{Calculate 1710 divided by 445, which is 3 with a remainder of 375.}

\text{Bring down 0, so that 3750 is large enough to be divided by 445.}

\text{Calculate 3750 divided by 445, which is 8 with a remainder of 190.}

\text{Bring down 0, so that 1900 is large enough to be divided by 445.}

\text{Calculate 1900 divided by 445, which is 4 with a remainder of 120.}

\text{Bring down 0, so that 1200 is large enough to be divided by 445.}

\text{Calculate 1200 divided by 445, which is 2 with a remainder of 310.}

<span>Therefore, 25099.506 ÷ 4.45 ≈ 5640.33842</span>

A research company desires to know the mean consumption of meat per week among people over age 23. A sample of 164 people over a
Elan Coil [88]

Answer:

The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.8}{2} = 0.1

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.1 = 0.9, so z = 1.28

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.28*\frac{0.7}{\sqrt{164}} = 0.07

The lower end of the interval is the mean subtracted by M. So it is 4.1 - 0.07 = 4.03 pounds

The upper end of the interval is the mean added to M. So it is 4.1 + 0.07 = 4.17 pounds

Rounded to one decimal place

The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.

What is the slope of the line that goes through the points (1,-5) and (4,1)?
lesya692 [45]

Answer: m = 2

Step-by-step explanation:

What we know:

  • The slope needs to pass through the points (1, -5) and (4, 1)
  • There are 4 potential slopes given to us- only one is correct
  • We need to find the slope and make sure it is an option

How to solve:

By using the slope equation and the two points given to us, we can calculate the slope.

Process:

  • Set up equation                                                 (y2 - y1) / (x2 - x1)
  • Substitute                                                            (1 +5 ) / (4 - 1)
  • Simplify                                                                6 / 3
  • Simplest form                                                      2/ 1 =

Slope =                                                                          2

Solution: m = 2

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist
maw [93]

Answer:

<em>The percent error of the cyclist's estimate is 5.63%</em>

Step-by-step explanation:

<u>Percentages</u>

The cyclist estimates he will bike 80 miles this week, but he really bikes 75.5 miles.

The error of his estimate in miles can be calculated as the difference between his estimate and the real outcome:

Error = 80 miles - 75.5 miles = 4.5 miles

To calculate the error as a percent, we divide that quantity by the original estimate and multiply by 100%:

Error% = 4.5 / 80 * 100 = 5.625%

Rounding to the nearest hundredth:

The percent error of the cyclist's estimate is 5.63%
