How to write 2.31818 as a mixed fraction

Mathematics
1 answer:
Elenna [48]3 years ago
5 0

Answer:

2\frac{15909}{5000}

Step-by-step explanation:

To make 2.31818 into a fraction, you must first move it to the numerator and make 1 the denominator.

\frac{2.31818}{1}

And then you multiply it by 10,000 or you can say 10^5

\frac{2.31818}{1}*\frac{100000}{100000}

After you multiply you divide the numerator and denominator by 2.

\frac{231818/2}{100000/2}

And now this equals:

2\frac{15909}{5000}

Hope this helps!

Given that a 90% confidence interval for the mean height of all adult males in Idaho measured in inches was [62.532, 76.478]. Us
grigory [225]

Answer:

The confidence interval on this case is given by:

\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}} (1)

For this case the confidence interval is given by (62.532, 76.478)[/tex]

And we can calculate the mean with this:

\bar X = \frac{62.532+76.478}{2}= 69.505

So then the mean for this case is 69.505

Step-by-step explanation:

Previous concepts

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

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".  

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

\bar X represent the sample mean  

\mu population mean (variable of interest)  

\sigma represent the population standard deviation  

n represent the sample size  

Assuming the X follows a normal distribution  

X \sim N(\mu, \sigma)

The confidence interval on this case is given by:

\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}} (1)

For this case the confidence interval is given by (62.532, 76.478)[/tex]

And we can calculate the mean with this:

\bar X = \frac{62.532+76.478}{2}= 69.505

So then the mean for this case is 69.505

Clare is paid $90 for 5 hours of work. At this rate, how many seconds does it take for her to earn 25 cent?
Alla [95]
50 secs

as $90÷5hrs= 18 $ per hrs

$18÷60min=$0.30 per min

$0.30÷60sec=$0.005 per sec

$0.25÷$0.005= 50sec to make $0.25

so 50sec is the answer
