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

If a recipe calls for one half lb of chicken per person and you bought the chicken in kilograms, how much chicken is needed for

nirvana33 [79]

Answer:

chicken per 3 people ≅ 0.681kg.

Step-by-step explanation:

You have half a pound of chicken per person (1/2 lb / p) and since there are 3 people then 3 * (1/2 lb / p) will be needed 1.5 lb for every 3 people , but this amount must be in kilograms, so :

$1.5lb*\frac{0.454kg}{lb}$ ≅0.681kg.

Simplify the following expression. A.49 B.1/14 C.1/49 D.14

Anna35 [415]

Answer:

Step-by-step explanation:

Using the rules of exponents

• $a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

• $a^{-m}$ ⇔ $\frac{1}{a^{m} }$

Hence

$7^{-5/6-7/6}$ = $7^{-\frac{12}{6} }$ = $7^{-2}$ , then

$7^{-2}$ = $\frac{1}{7^{2} }$ = $\frac{1}{49}$ → C

The table on the left is that of a linear function, and the one on the right is that of an exponential function. Can you tell wh

Brut [27]

The correct answer is D.

As you can see, the exponential function grows by doubling the previous output with each increment of the input: start with 1, you double it to get 2, then you double it to get 4, 8 and so on.

On the other hand, the linear function adds 7 with each step. This means that the exponential function will eventually reach and pass the linear one, and will definitely be grater from that point on. In fact, if we continue the table, we get

$\begin{array}{c|c|c}\text{x value}&\text{linear}&\text{exponential}\\4&28&8\\5&35&16\\6&42&32\\7&49&64\\8&56&128\\9&63&256\end{array}$

and you can see how the exponential growth is much faster than the linear one.
