Answer:
If there are 1000 customers in the store one week, how many will purchase exactly one of these items
1000 CUSTOMERS*28%=280
Step-by-step explanation:
A The event that a persons buys a suit  
B The event that a person buys a shirt  
C The event that a person buys a tie  
  
 P(A)=  22%
 P(B)=  30%
 P(C)=  28%
 P(AB)=
11%
 P(AC)=
14%
 P(BC)=
10%
 P(ABC)=
6%
A u B u C Is the event that any item is bougth
AC u AC u BC Is the event that any two events occured
So the wanted probability is
P[(A u B u C )(AB u AC u BC)^c
P[(A u B u C )=P(AB)+ P(BC)+P(BC)
 P[(A u B u C ) =0.22+0.30+0.28-0.11-0.14.-0.10+0.06
                       =0,51
0,51=+0,23+P[(A u B u C )(AB u AC u BC)^c
         =0,28
1000 CUSTOMERS*28%=280
 
        
             
        
        
        
Answer:
Acute Triangle
Step-by-step explanation:
All angles are less than 90 degrees. 
 
        
             
        
        
        
Answer:
Gianna makes $18 per hour.
Step-by-step explanation:
Given Gianna makes 90$ for 5 hours. That means she should make  $  = 18$ every hour.
 $  = 18$ every hour.
Therefore we have:
a.
HOURS                    DOLLARS
   1                                   18
   2                                  36
   3                                  54
   4                                   72
   5                                   90
   6                                   108
   7                                   126
b.
For the tabular column mark Hours on the x - axis and Dollars on the Y - axis. It can be plotted from the above table easily.
c.
If Gianna works for 8 hours she would have made 8 X 18 = 144$.
So, she will earn 144$ in 8 hours.
d.
To make 60$ she would have to work  hours = 3.33 hours.
 hours = 3.33 hours. 
 
        
             
        
        
        
The answer is c.
