To divide fractions you flip the second one and then multiply the new fractions
9 16 9 5 45
--- ÷ ---- = ---- × ------ = ------
2 5 2 16 32
then simplify
45/32= 1 13/32
I hope I've helped!
Answer:
It would be 36
Explanation:
<em>First:</em>
<em>Convert any mixed numbers to fractions.</em>
<em>Then your initial equation becomes:</em>
<em>108/1 ×1/3</em>
<em> </em>
<em>Applying the fractions formula for multiplication,</em>
<em>=108×1/1×3 = 108/3</em>
<em> </em>
<em>Simplifying 108/3, the answer is</em>
<em>=36</em>
hope it helped. :)
Using the z-distribution, it is found that the 95% confidence interval for the difference is (-1.3, -0.7).
<h3>What are the mean and the standard error for each sample?</h3>
Considering the data given:
<h3>What is the mean and the standard error for the distribution of differences?</h3>
The mean is the subtraction of the means, hence:
The standard error is the square root of the sum of the variances of each sample, hence:
<h3>What is the confidence interval?</h3>
It is given by:
We have a 95% confidence interval, hence the critical value is of z = 1.96.
Then, the bounds of the interval are given as follows:
