Step-by-step explanation:

Answer:

-3 < x ≤ 1

Step-by-step explanation:

To our left, we have an unshaded circle at -3. This means that -3 is included in the possible value of x. And as such, we can say -3 < x.

To our right, we have a shaded circle at 1. This means 1 is included in the possible values of x. And as such, we can say x ≤ 1.

Thus, we can represent the two statements as one, thus:

-3 < x ≤ 1

Answer:

P(x) = 5.15 x + 1500

Step-by-step explanation:

The monthly operating costs = $1500 plus $0.85 per delivery.

The service generates revenue= $6 for each delivery

If in a given month the deliveries number was = x  then;

Operating cost  function : C(x) = 0.85x + 1500

Revenue generated function R(x) = 6x

Profit = Revenue - cost

P(x) = R(x) - C(x)

P(x) = 6x - 0.85x + 1500

P(x) = 5.15 x + 1500

Answer:

no

Answer:

≈0.52

Step-by-step explanation:

The value of the quantity after 8.7 decades is 0.521.

Exponential growth is the increase of rate of change and thus results in the increase of the final quantity.

Exponential decay is the decrease in rate of change and hence results in the decrease of the final quantity.

Given that,

Initial value of the quantity = 230

Rate of decay = 7% per year = 0.07

Time = 8.7 decades = 87 years

The formula for exponential decay is,

A = P e^(-k t)

Here A is the final value of the quantity

P is the initial value of the quantity

k is the decay rate

t is the time.

Substituting the given values,

A = 230 × e^(-0.07 × 87)

A = 230 × e^(-6.09)

   = 0.521

Hence the final quantity after 8.7 decades is 0.521.

Answer:

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Step-by-step explanation:

Step(i):-

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

Step(ii):-

Let 'X' be the random variable in binomial distribution

[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

n=3 and r=3

[tex]P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}[/tex]

[tex]P(X=3) = 1 (0.47)^{3}[/tex]

P(X=3) = 0.1038

Final answer:-

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Answer:

[tex]x=1, y=2[/tex]

Step-by-step explanation:

[tex]\begin{bmatrix}-2x-5y=-12\\ 10x-4y=2\end{bmatrix}[/tex]

Isolate x for [tex]-\:2x\:-\:5y=-12[/tex]

[tex]-\:2x\:-\:5y=-12[/tex]

Add 5y to both sides.

[tex]-2x-5y+5y=-12+5y[/tex]

Simplify.

[tex]-2x=-12+5y[/tex]

Divide both sides by 2.

[tex]x=-\frac{-12+5y}{2}[/tex]

Substitute x for [tex]-\frac{-12+5y}{2}[/tex].

[tex]\begin{bmatrix}10\left(-\frac{-12+5y}{2}\right)-4y=2\end{bmatrix}[/tex]

Simplify.

[tex]\begin{bmatrix}-29y+60=2\end{bmatrix}[/tex]

Isolate y for [tex]-29y+60=2[/tex]

[tex]y=2[/tex]

Substitute y in [tex]-\frac{-12+5y}{2}[/tex] for 2.

[tex]x=-\frac{-12+5\cdot \:2}{2}[/tex]

Simplify.

[tex]x=1,\:y=2[/tex]

Answer:

Total Area = 84 feet

Step-by-step explanation:

Triangle = 1/2 (3 × 4) = 12/2 = 6 ft

Rectangle 1 = 7 × 4 = 28 ft

Rectangle 2 = 5 × 10 = 50 ft

Total Area = 6ft + 28ft + 50ft = 84ft

Answer:

11 years

Step-by-step explanation:

Given that:

Advert A:

Principal, p = $24,200

Interest rate, r = 6.5% = 6.5/100 = 0.065

Time, t =?

Total Repayment, A = $41,503

Using the relation :

A = p(1 + rt)

Plugging our values

41503 = 24200(1 + 0.065t)

41503 / 24200 = 1 + 0.065t

1.715 = 1 + 0.065t

1.715 - 1 = 0.065t

0.715 = 0.065t

t = 0.715 / 0.065

t = 11 years

Answer:

Burgers: 12

Step-by-step explanation:

Answer: 2430 bacteria.

Step-by-step explanation:

When we have a quantity A, and we have an increase of the X%, the new quantity can be written as:

A + (X%/100%)*A

In this case, we have A = 10 bacteria.

And X% = 200%.

Then if we start with 10 bacteria.

After one day, we will have:

10 bacteria  + (200%/100%)*10 bacteria

= 10 bacteria + 2*10 bacteria = 3*10 bacteria.

After another day, we will have:

3*10 bacteria + (200%/100%)*(3*10 bacteria)

3*10 bacteria  + 2*(3*10 bacteria)

3*(3*10 bacteria)

10 bacteria*(3)^2

We already can see the pattern here.

After t days, we will have:

10 bacteria*(3)^t.

This is the equation f(t) we wanted:

f(t) =10 bacteria*(3)^t

after 5 days, we will have:

f(5) = 10 bacteria*(3)^5 = 2430 bacteria.

Answer:

=20 becuase you Multiply all terms by the same value to eliminate fraction denominators

Answer:

p = 20

Step-by-step explanation:

In order to solve for "p", you need to isolate p completely on one side of the equal sign. to do such, simply multiply by "4" both sides ofthe equation, to cancel out the 4 in the denominator and get:

p = 5 * 4 = 20

Answer:

1 and 17/25

Step-by-step explanation:

First, you make it into a fraction. So because percents are out of 100, it would be 168/100. Then, you take 100 out of it to get a mixed number, 1 and 68/100, and then simplify 68/100 by dividing both sides by the greatest common factor, which is 4. 68/100÷4=17/25. The answer would be 1 and 17/25.

Hi there!

[tex]\large\boxed{x = 16}[/tex]

x / 2 - 5 = 3

Begin by adding 5 to both sides to isolate for x:

x / 2 - 5 + 5 = 3 + 5

x / 2 = 8

Multiply both sides by 2 to have "x" alone on the left-hand side:

(x / 2) × 2 = 8 × 2

x = 16

Answer:

because if x is 16

16/2 = 8 and so on 8 - 5= 3 so that is the answer

Answer:

9

Step-by-step explanation:

f(11) means that x = 11 (plug it in)

f(11) = 1/4(5-11)^2

      = 9

The value of f(11) is 9.

The function of a given term is a form of an expression where element of the domain consists of a unique identity and each input value of a function is allocated to only one output value.

From the parameters given;

[tex]\mathbf{f(x) = \dfrac{1}{4}(5 - x)^2}[/tex]

we are to replace x with 11 wherever we see x

∴

[tex]\mathbf{f(11) = \dfrac{1}{4}(5 - 11)^2}[/tex]

[tex]\mathbf{f(11) = \dfrac{1}{4}(-6)^2}[/tex]

[tex]\mathbf{f(11) = \dfrac{1}{4} \times 36}[/tex]

f(11) = 9
