To Find :-

  • The algebraic equations to solve the above problem .

Solution :-

Let ,

  • Large number = L
  • Small number = S

— According to first statement ,

  • L - S = 4
  • L - S - 4 = 0

— According to second statement ,

  • 3L + 4S = 54
  • 3L + 4S - 54 = 0 .

These equations matches with the second option b .

Option b is the correct answer.

Answer:

(3x)(x-2)(x-1)

Step-by-step explanation:

First we can factor out the 3x from each and are then left with x^2-3x+2. Now we can go ahead and factor. Looking for two variables that multiply to become positive 2 and add to become negative 3, we get negative 2 and negative 1. We now know that both (x-1) and (x-2) are factors. We now have all three factors and we can multiply to check if we get the right answer, and we do.

Determine whether 2x+2y= -6 is a function?
Archy [21]

Answer:

It's a function because when you simplify it becomes y=-x-3. the only reason it wouldn't be a function would be if the equation were to be x = a random number that is not a variable. The equation would not pass the vertical line test which is the requirement to see if an equation is a function.

Simply put, it's a function.

The combined volume of all the tanks at an aquarium is 1.25 X 106 gallons. The aquarium plans to install a new dolphin tank with
DaniilM [7]

1. The combined volume of all the tanks at the aquarium is written in Scientific notation. Keeping this on mind, you can write it as following:

(1.25)(10^{6})=1,250,000gallons

2. Now, you must sum the combined volume of all the tanks and the volume of  the new tank to calculate the total volume of all of them:Vt=1,250,000gallons+250,000gallons\\Vt= 1,500,000gallons

3. Now, you can write the result in Scientific notation, as following:

Vt=(1.5)(10^{6}) gallons

The answer is: (1.5)(10^{6}) gallons

N = 9
g100num [7]

Answer:

The <em>p</em>-value is 0.809.

Step-by-step explanation:

In this case we need to perform a significance test for the standard deviation.

The hypothesis is defined as follows:

<em>H</em>₀: <em>σ</em>₀ = 4 vs. <em>Hₐ</em>: <em>σ</em>₀ ≤ 4

The information provided is:

<em>n</em> = 9

<em>s</em> = 3

Compute the Chi-square test statistic as follows:

\chi^{2}=\frac{(n-1)s^{2}}{\sigma_{0}^{2}}

     =\frac{(9-1)\cdot (3)^{2}}{(4)^{2}}\\\\=\frac{8\times 9}{16}\\\\=4.5

The test statistic value is 4.5.

The degrees of freedom is:

df = n - 1

   = 9 - 1

   = 8

Compute the <em>p</em>-value as follows:

p-value=P(\chi^{2}_{9}>4.5)=0.809

*Use a Chi-square table.

Thus, the <em>p</em>-value is 0.809.
