Answer:
They boarded the bus in descending alphabetical order: Karen, Jose, Isabel and Harry
Step-by-step explanation:
In order of there name: Harry, Isabel, Jose, and Karen
If Karen was the first to board a bus, this means that Jose will be the second to board the bus, third is Isabel and Harry will be fourth.
It can be concluded that they boarded the bus in descending alphabetical order.
Answer:

Step-by-step explanation:
When two lines are parallel means that their slopes are equal. Therefore the line AB will have same slope to a parallel second line,
.
To obtain the slope from the line AB, we need two points, so the general equation will be:

The typical equation of a line is written as y = mx + b
The second line will pass through point (2, -1), so we can substitute:
y2 = mX2 + b
-1 =
(2) + b
then the interception is 
Now to obtain a general equation for the second parallel line will be:
y =
X + b
y =
X -
(2)-1
Finally we get:
y =
(x-2)-1
Answer:
x=2 y=1
Step-by-step explanation:
12 times 2 equals 24
24 time 1 equals 24
24+24=48
Use the hypergeometric distribution.
M=number of Men=5
F=number of women=4
m=number of men elected=2
f=number ow women elected=2.
Assuming equal chance to get elected, then
P(2M,2F)=C(M,m)*C(F,f)/C(M+F,m+f)
=C(5,2)*C(4,2)/C(9,4)
=10*6/126
=10/21
Reference: Hypergeometric distribution.
The first and only stop of the flight can be Boise, Omaha or Chicago. This means there are 3 possibilities where to stop. From thee the flight connects to New York City, either to La Guardia or to JFK Airport.
1 possible route: Seattle-Boise-La Guardia
<span>2 possible route: Seattle-Omaha-La Guardia
</span><span>3 possible route: Seattle-Chicago-La Guardia
</span><span>4 possible route: Seattle-Boise-NYC
</span><span>5 possible route: Seattle-Omaha-NYC
</span><span>6 possible route: Seattle-Chicago-NYC
</span>
Or in other words: There are two airports where the flight can arrive and for each of them there are three possible routes. So, in total there are 2*3=6 possible routes.
