Contact [7]3 years ago

6 0

Answer:

it would be 58

Step-by-step explanation:

if you do 72 x 417 it would be 5 at the top and 360 would be at the bottom so it would be 417-360 which is 57 and the six at the top u would drop so now it is 576 so if you do 72 x 8 it would be 576 so u would put the 8 with the 5 and subtract the 576 - 576 and that is 0 BOOM

gtnhenbr [62]

Answer:

2 hours * (47 miles / hour) = 94 miles

multiply the value in miles per hour by the conversion factor '1.609344'.

So, 2.2 miles per hour = 2.2 × 1.609344 = 3.5405568 kilometers per hour.

Natalka [10]

Using the t-distribution to build the 99% confidence interval, it is found that:

The margin of error is of 3.64.

The 99% confidence interval for the population mean is (19.36, 26.64).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 21 - 1 = 20 df, is t = 2.086.

The other parameters are given as follows:

$\overline{x} = 23, s = 8, n = 21$

The margin of error is given by:

$M = t\frac{s}{\sqrt{n}} = 2.086\frac{8}{\sqrt{21}} = 3.64$

Hence the bounds of the interval are:

$\overline{x} - M = 23 - 3.64 = 19.36$

$\overline{x} + M = 23 + 3.64 = 26.64$

The 99% confidence interval for the population mean is (19.36, 26.64).
