Answer:

A car that is 3 and a half years old would cost $18,000

Step-by-step explanation:

Using the given equation, [tex]y=-2x+25[/tex], we replace 'x' with '3.5' and solve for 'y'.

[tex]y=-2(3.5)+25[/tex]

[tex]y=-7+25[/tex]

[tex]y=18[/tex]

Dollar values on the graph are expressed in thousands. Thus, we multiply 18 by 1,000 to get $18,000

Answer:

  sum = ∑[n=1,5] 4^(n-4)

Step-by-step explanation:

First of all, you need to be able to describe the n-th term.

Here, we  have ...

  term #: 1, 2, 3, 4, 5

  value: 4^-3, 4^-2, 4^-1, 4^0, 4^1

That is, the exponent of 4 is 4 less than the term number. So, the n-th term is 4^(n-4). The sum of the 5 terms shown is then ...

  [tex]\displaystyle sum=\sum_{n=1}^5{4^{n-4}}[/tex]

Answer:

In the long run there are 0.02647 machines in the system queue.

Step-by-step explanation:

From the equation of the Finite Population Model of form M/M/1 with a finite source ,the average number of fax machines in the system to be maintained is given as :

[tex]L=\dfrac{\lambda^2}{\mu(\mu-\lambda)}[/tex]

Here

[tex]\lambda=\dfrac{Number\ of\ machines}{Time\ between\ Service}\\\lambda=\dfrac{3}{5\ hr}\\\lambda=0.6\ hr^{-1}[/tex]

So the equation becomes:

[tex]L=\dfrac{\lambda^2}{\mu(\mu-\lambda)}\\L=\dfrac{0.6^2}{4(4-0.6)}\\L=0.02647[/tex]

So in the long run there are 0.02647 machines in the system queue.

Answer:

-12

Step-by-step explanation:

Answer:

0.625

Step-by-step explanation:

Given :

Ambell company uses or procures batteries from two manufacturers.

The life of a battery in critical tool is at = 32 hours

Ambell uses 70% of its batteries from manufacturer 1 and out of that 90% batteries lasts for about 40 hours.

Similarly, 75% of the batteries procured from the manufacturer 2 lasts for about 40 hours.

Therefore, the probability that a battery is form manufacturer 1 is :

[tex]$\frac{0.4 \times 0.25}{(0.6 \times0.1)+(0.4 \times 0.25)}$[/tex]

= 0.625

Answer:

Yes, the dog food will last a whole week

Step-by-step explanation:

1 pound=16 ounces, so

10 pounds=10*16=160 ounces.

There are 7 days in a week, so if Laura feeds her dogs 22 ounces per day, she will need 7*22=154 ounces to last a whole week.

She buys 160 ounces, which is greater than 154, so yes.

Answer:

Yes, the food will last the whole week

Step-by-step explanation:

10 pounds is 160 ounces. If you multiply 22 by 7 you'll get 154.

...Answer:

Step-by-step explanation:

Answer:

Let x=numerator,

y=denominator.

y=x+7 - - - - - (i)

(x+3)/(y+3) = 2/3

(Cross multiply)

3(x+3)=2(y+3)

3x+9=2y+6

(subtract 9 from both sides)

3x+9–9=2y+6–9

3x=2y+6–9

3x=2y-3 - - - - - - - (ii)

(substitute the value of equation (i) into (ii))

3x=2(x+7)-3

3x=2x+14–3

3x=2x+11

(subtract 2x from both sides)

3x-2x=2x+11–2x

x=11.

(substitute the value of x into equation (i))

y=7+11

y=18.

so numerator =11,

numerator =11,denominator = 18.

So original fraction is 11/18.

3/11th of original fraction is

= 11/18 x 3/11

= (11x3)/(18x11)

= 3/18

=1/6.

Answer = 1/6.

Answer:

Step-by-step explanation:

let numerator be x and denominerator be y

according to the question equation is

1+x /7+x+6=1/2( do cross multiplication)

7+x+6=2(1+x)

13+x=2+2x

13-2=2x-x

11=x

numerator =x+1=11+1=12

therefore numerator is 12

for denominerator

substitute the value of x in (7+x+6)

=7+11+6

Answer:

9 boxes

Step-by-step explanation:

The number of boxes that has the same number of marbles is 9.

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The total number of marbles.

= 55 + 143

= 198

The number of boxes where each box has the same number of marbles.

= 198 / 22

= 9

Where each box will have 22 marbles.

Thus,

The number of boxes is 9.
