1/12
Step-by-step explanation:
a) This is a counting problem 4*3*2*1 = 24 different ways.
b) 1 * 2 * 1 * 1 = 2 ways
This is one you should try.

You can't get another way.
c)
There are 2 ways that Jim can arrive first and Kim Last shown in b
2/24 = 1/12
Answer:
Min = 11
Q1 = 13
Median = 15
Q3 = 17
Max = 22
Step-by-step explanation:
The five-number summary that is displayed by the box plot above are:
The minimum value: the data value at the start of the whisker to your left = 11
The Q1 value: the data value at the beginning of the edge of the rectangular box = 13
The Median value: the data value at the vertical line that divides the rectangular box into two = 15
Q3 value: the data value at the end of the rectangular box = 17
Max: 22
Answer:
16
Step-by-step explanation:
AC= 15x+2
BD= 9x+14
AE= 1/2AC
AC=BD
1) First we must find what x is. Because AC and BD are the same length, we can set them equal to each other to find x.
15x+2=9x+14
6x=12
x=2
2) Now that we know x, we plug the value for x back into the equation for AC.
AC=15x+2
AC=15(2)+2
AC=30 +2
AC= 32
3) Finally, we can find AE because it is half of AC.
AE=1/2AC
AE=1/2(32)
AE=16
hope this helps!! :)
Let
x----------> the number of students
y---------> the time in minutes
we know that
<span>If the time varies inversely with the number of students
</span>so
y=k/x
for x=3
y=16 min
16=k/3---------> k=48
y=48/x
for x=2
y=48/2-------> y=24 minutes
the answer is
24 minutes
