Answer:
Median = 45
Step-by-step explanation:
Since the given data set is already in ascending order, we we just have to find the middle most number of the data set:
There are 2 middle numbers 40 and 50, so to find the middle most number find their average:
(40 + 50) / 2 = 45
Median = 45
Hope this helps!
Uee two points on the line to find the slope.
(-1,2) and (1,-4)
Slope = change in y over change in x;
Slope = (-4 - 2)/ (1 - -1) = (-6/2) = -3/1 = -3
The y intercept is y value where the blue line crosses the y axis, which is at -1
The equation would be y = -3x-1
<span>n 19 -----------> AB/AC=(4/6)=2/3<span>
n 20 ------------> BC/CD=[AC-AB]/[AD-AC]=(6-4)/(9-6)=2/3
n 21-------------> BD/AE=[AD-AB]/[AE]=(9-4)/(12)=5/12
n 22 7 and 28 find the geometric mean of the two number
step 1
Multiply the two numbers together:
28*7=196
step 2
take the square root:
<span><span>sqrt(196)=14
</span>the answer is 14</span>
n 23 Simplify the ratio 10 ft/30 in---> divided between 2 both members
5 ft/15 in-----> divided between 5 both members ---> 1 ft/3 in</span><span>
n 24
<span>if AB=4 -------></span></span> AB~FG

then
</span></span>AB*factor=FG-------- > 4*factor=8-- > factor=8/4=2
the figure ABCDE is half of the figure FGHJK
then<span>
BC=4
AE=CD=5
and
ED=6
therefore
<span>the perimeter=[4+4+5+5+6]=24 units</span></span>
