What is the median of the following 7 scores?

1 answer:

8 0

First, you want to put all the numbers in order from least to greatest.

21, 33, 33, 42, 67, 79, 89

Now, you can use this song to help remember how to do these problems.

Cross off the sides till you get to the center. 1 is good, 2 is bad. (If you get two numbers in the middle) add then divide by two.

Cross off 21, then 89, then 33, then 79, then 33, then 67. Now, you're left with 42 in the middle. That is your median. Hope this helps! :)

What is the area of the regular octagon below? 9m

Feliz [49]

Answer:

No diagram and no explanation what 9 is.

However, if it is an octagon with each side equal to 9 then

area = (# of sides * side^2) / (4 * tan (180 # of sides))

area = 8 * 9 * 9 / (4* tan (180 / 8)

area = 648 / 4 * 0.41421

area = 391.1059607446

answer is C

Given: EFGH inscribed in k(O) m∠FHE = 45°, m∠EGH = 49° Find: m∠FEH

hodyreva [135]

Answer:

$m$

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

step 1

Find the measure of arc EF

$m$

we have

$m$

substitute

$45\°=\frac{1}{2}(arc\ EF)$

$arc\ EF=90\°$

step 2

Find the measure of arc EH

$m$

we have

$m$

substitute

$49\°=\frac{1}{2}(arc\ EH)$

$arc\ EH=98\°$

step 3

Find the measure of arc FGH

$arc\ FGH=360\°-(arc\ EH+arc\ EF)$

substitute the values

$arc\ FGH=360\°-(98\°+90\°)$

$arc\ FGH=172\°$

step 4

Find the measure of angle FEH

$m$

we have

$arc\ FGH=172\°$

substitute

$m$

Jenna concludes that (4,9) is the solution to the system of these two equations. which of the following justifies her conclusion

nalin [4]

Answer:

a. The point (4,9) appears in both tables

Explanation:

Note: This question can be solved without the need of the tables

A solution of a system of equations is defined as a point (or set of points) that satisfy both equations

This means that, this point should belong to all the equations in the system

Now, a table is used to show a set of points that belong to a certain line

This means that, all vales in the table belong to the line they represent

Since the point (4,9) appears in both tables, therefore, it belongs to both lines and, therefore, is a solution to the system of equations consisting of these two lines

Hope this helps :)

A town has a small zoo. These two lists show information about the zoo.

Natasha_Volkova [10]

Answer:

For which list does the total number have meaning? (What to see at the zoo)

For the list of facts it (does not) make sense to add the cost of a past, the area and the employees because these quantities (cannot) be expressed using the same unit. The number of 168 (does not) have meaning for the list

Step-by-step explanation:

Area is usually described in square feet while a population has no unit and a price is described in dollars therefore the list of facts has no meaning ( i got this question correct)
