You first find the median, which is the central term if the number of terms is odd, or the average of the two central terms if the number of terms is even...

This is an odd number of elements and the center term, the median, is 22

Now you get the "median" from the first term to the median, which is (20+21)/2=20.5 That's the first quartile...

Now you get the "median" from the central term to the last term which is:

(24+24)/2=24. That's the third quartile...

Now the interquartile range is Q3-Q1 so:

24-20.5=3.5

So the interquartile range is 3.5

Two functions are graphed on the coordinate plane.

rosijanka [135]

Answer:

Option B

Step-by-step explanation:

We can see that, from the picture provided, the graphs intersect at points( 0, 4 ) and ( - 4, 4 ), respective to functions f( x ) and g( x ). These intersection points makes each function equivalent to one another, and hence -

Function f( x ) where x = - 4 / Function g( x ) where x = - 4,

$f( - 4 ) = 4,\\g( - 4 ) = 4\\----------\\f ( - 4 ) = g ( - 4 )$

Respectively function f( x ) where x = 0 / Function g( x ) where x = 0,

$f( 0 ) = 4,\\g( 0 ) = 4\\----------\\f ( 0 ) = g ( 0 )$

<u><em>Your solution should be option b, " f(-4) = g(-4) and f(0) = g(0) "</em></u>

$m\angle BCA=180^o-5x$

$\angle CAB=\angle ACD\\\\m\angle CAB=33^o$

In the triangle ABC:

$m\angle ABC+m\angle BCA+m\angle CAB=180^o\\\\2x+180^o-5x+33^o=180^o\\\\-3x+213^o=180^o\ \ \ |-213^o\\\\-3x=-33^o\ \ \ |:(-3)\\\\x=11^o$

Gabriella and her children went into a restaurant where they sell hotdogs for $4 each and tacos for $2 each. Gabriella has $30 t

Lorico [155]

A possible solution to the inequality is 2 hotdogs and 8 tacos.

Let x represents the number of hotdogs purchased and y represents the number of tacos purchased.

Gabriella has $30 to spend and must buy a minimum of 9 hotdogs and tacos altogether.

Hence:

4x + 2y ≤ 30 (1)

x + y ≥ 9 (2)

Also:

x ≥ 2 (3)

A possible solution to the inequality is 2 hotdogs and 8 tacos.

Find the mean and the median of the data set..... 200,167,185,212,195,193,188,140

astraxan [27]

You Will Add Up All The Number Then Divide By The Total Number You Have In All
The Mean Is 185
You Put All The Number In Order For The Median
140,167,185,188,193,195,200,212
So You Have Two Number Which Are 188 and 195
You Will Add 188 + 195=383
Now You Divide 383 By 2 Which Is 191.5
