Answer:

n = 5

Step-by-step explanation:

Using the rules of exponents

a^{m} × a^{n} = a^{(m+n)} ,

(a^m)^{n} = a^{mn}

Given

(3^{n}.3^{2} ) ^{4} = 3^{28} , then

(3^{(n+2)}) ^{4} = 3^{28}

3^{4(n+2)} = 3^{28}

Since the bases on both sides are equal, both 3 then equate the exponents

4(n + 2) = 28 ← divide both sides by 4

n + 2 = 7 ( subtract 2 from both sides )

n = 5

22% of the customers visiting the suit department of a certain store will purchase a suit, 30% will purchase a shirt and 28% wil
Ulleksa [173]

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
