A 5/3
Step-by-step explanation:
Answer:
The critical value of <em>t</em> is 2.000.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean in case the population standard deviation is not known is:
The information provided is:
<em>n</em> = 57
Confidence level = 95%
As the sample size is large enough, i.e. <em>n</em> = 57 > 30 the sampling distribution of sample mean can be approximated by the normal distribution.
The distribution of sample statistic is normal and the sample size is quite large. This implies that it is appropriate to use a <em>t</em>-interval.
Compute the critical value of <em>t</em> as follows:
*Use a <em>t</em>-table for the critical value.
Thus, the critical value of <em>t</em> is 2.000.
Answer:
the answer would be no shape.
Step-by-step explanation:
imagine you have the paper in your hands, if you start from the left you would have to fold the paper 3 times, then when it comes to the last 2 squares, you wouldnt be able to close the cube. hope this helps
First of all
x^2 +10x - 18
use
x = (-b plus or minus (<span>√<span></span></span>(b^2-4ac)))/2a
you will get
(x+5−(<span>√<span><span><span>43)</span></span><span></span></span></span>)(x+5+(<span>√<span><span><span>43</span></span><span>))</span></span></span>
