Answer:

Step-by-step explanation:

We know the bottom of the triangle is 5 cm and the top of the rectangle is 5 cm, but we need to find the sides.

The height of the triangle is 8 cm, we know this as we do 18 - 10 = 8 because we subtract the rectangle from the whole figure which leaves us the triangle.

We split the triangle into 2 parts. The bottom part is now each 2.5 cm.

Then we use the Pythagorean theorem.

Check my work on the picture for how I do it for which it leads to the sided of the triangle.

Now adding the sides of the whole perimeter we just focus on the outer regions.

Two parts from the triangle which both add up to 15.20 cm and the rectangle is 25 cm, you ignore the segment inside the figure.

25 + 15.20 = 37.20 cm.

Answer:

The measure of center would this student want his teacher to use is the

median $= {\bf 75}$

Mean $= {\bf 5}$ , Mode $={\bf 82}$ , Range $={\bf40}$ and Interquartile Range $= {\bf 32}$

Step-by-step explanation:

Given Data set $= 50,55,70,75,82,82,90$

Number of elements in data set $= 7$

To find Mean

The ‘Mean” is the average of a set of numbers.

The "Mean" is computed by adding all of the numbers in the data together and dividing by the number of elements contained in the data set.

Mean $= \frac{50 +55 +70 + 75 + 82 + 82 + 90} {7 }$

Mean $= \frac{504}{7}$

Mean $= 5$

Median

The “Median” is the middle value of a set of ordered numbers.

Therefore Median $=75$

Mode

The "Mode" for a set of data is the value that occurs most often.

It is not uncommon for a data set to have more than one mode. This happens when two or more elements occur with equal frequency in the data set.

Therefore Mode $=82$

Range

The "Range" is the difference between the largest value and smallest value in a set of data.

Range $= 90-50$

Range $= 40$

Interquartile Range

The “Interquartile Range” is the difference between smallest value and the largest value of the middle 50% of a set of data.

The "Interquartile Range" is from Q1 to Q3:

To find the interquartile range of a set of data:

The cut the list into four equal parts

. The quartiles are the “cuts”

The interquartile range is the distance between the two middle sets of data

Interquartile Range $= Q_3-Q_1$

Interquartile Range $= 82-50$

Interquartile Range $= 32$

Step-by-step explanation:

$\sqrt{-80}$

$\sqrt{80*i^2}$

i^2 is -1

$i\sqrt{80}$

$i\sqrt{4^2 * 5}$

$4i\sqrt{5}$

Answer: $4i\sqrt{5}$
