An improper double integral can often be computed similarly to an improper integral of one variable. the first iteration of the following improper integral is conducted just as if it were a proper integral. one then evaluates an improper integral of a single variable by taking appropriate limits. evaluate the following improper integral as an iterated integral. integrate infinity ? infinity integrate infinity ? infinity 1/(x^2+16)(y^2+4) dx dy integrate infinity ? infinity integrate infinity ? infinity 1/(x^2+16)(y^2+4) dx dy =

Step-by-step explanation:

We are given the following improper integral:

Above double integral can be written as follows:

When we have improper integral with two infinite bounds, we are separating them into two parts.

So let's calculate them one by one.

First,

Since,

Second,

Since,

Hence,

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
