Step-by-step explanation:

Answers are: - 21 & 7

Let the required number be x

$\therefore \: x \div 3 = - 11 + 4 \\ \\ \therefore \: \frac{x}{3} = - 7 \\ \\ \therefore \: x = - 7 \times 3 \\ \\ \therefore \: x = - 21 \\ \\ 4(x - 3) = 16 \\ (x - 3) = \frac{16}{4} \\ x - 3 = 4 \\ x = 4 + 3 \\ x = 7$

Small "Mom and Pop firms", like inner city grocery stores, sometimes exist even though they do not earn economic profits. How ca

sweet [91]

Inner cities are identified as the central area of a major city. It is mostly composed of multi-floored townhouse and apartment buildings. Thus, its population density is quite large.

Small "mom and pop firms" thrive in this community because they are conveniently located in the hub of the inner cities. People who live in this area usually do so because they find it easier to commute to work. They would rather buy their food and staples in stores nearest to their place rather than brave the traffic and worry about parking spaces when they go out for groceries and such.

Added to their location, "mom and pop firms" also give out family bonds to their customers. They build rapport and look out for each other in their community.

Nancy found that x=1 is one solution to the quadratic equation (x 2)2=a. what is the value of a?

trasher [3.6K]

The value of the a in the quadratic equation is 4.

According to the statement

we have given that the x = 1 and the given equation is (2x)^2=a

And we have to find the value of A here.

So, For this purpose, we know that the

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared.

And the given quadratic equation is

(2x)^2 = a

we know that the x = 1 and put the value of x in it then

(2(1))^2= a

(2)^2= a

a = 4.

Now for rechecking of the value, put a = 4 in the given equation then

(2x)^2 = a

Put a = 4

Then

(2x)^2 = 4

2x = 2

And the value of x become

x = 1.

Which equal to the given value of the x which is 1.

So, The value of the a in the quadratic equation is 4.

Potential customers arrive at a full-service, one-pump gas station at a Poisson rate of20 cars per hour. However, customers will

Sophie [7]

Answer:

a) 19/20

b) 1/20

Step-by-step explanation:

a) calculate the fraction of the attendants time will be spent servicing cars

l / L > 0 = Ц / [ Ц - λ ] = 20 --- ( 1 )

Ц (service ) = 15 hour

∴ λ ( arrival rate ) = 14.25

P = λ / Ц = 14.25 / 15 = 0.95 = 19/20

<u>b) Fraction of potential customers lost </u>

Ls = P / ( 1 - P )

where ; P = 19/20

Ls ( fraction of potential customers lost ) = 19/20 / ( 1 - 19/20 ) = 19

hence proportion of customers lost = 1 - 19/20 = 0.05 = 1/20
