I got you hun!

27= 3x is the equation you will need

27 is the total the coach needs making it the total. Since each pack comes with 3 you will mutiply the amount of pack, or x, by 3. 

X=9 

we know this because if you divide 3 by 27 to get it on the other side we get 9. This means the coach needs to buy 9 packs of baseballs for the team.

27=3(9) 

Hope this helps!

14. Martha y Raúl tomaron en conjunto 175 fotos, de éstas Raúl tomó 77, ¿cuál es la ecuación algebraica que permite conocer cuán
Evgesh-ka [11]

Tenemos un problema algebraico.

Veremos que Martha saco 98 fotos

La información que tenemos es:

Martha y Raúl tomaron un total de 175 fotos.

Raúl tomo 77.

Para encontrar el número de fotos que saco Martha, simplemente debemos calcular la diferencia entre la cantidad total de fotos que sacaron y las que sabemos que saco Raúl:

175 - 77 = 98

Podemos así concluir que Martha saco 98 fotos

Bryan purchases a new boat. The expression below represents the value of the boat after x years. 22000(0.88)^(X+2)
bogdanovich [222]
<h3>Answer:</h3>

<em>None of the above</em>. All the answers refer to <em>price</em>. The given equation refers to <em>value</em>. We imagine price may stay the same or actually increase year-to-year. The problem statement gives insufficient information to conclude anything about <em>price</em>.

Math is about attention to detail. The equation tells you ...

... The <em>value</em> of the boat decreases by 12% every year.

<h3>Step-by-step explanation:</h3>

The value of the boat is multiplied by 0.88 each time X increases by 1. That means the value is 88% of what it was the year before, <em>a decrease of 12%</em>.

Suppose a research paper states that the distribution of the daily sea-ice advance/retreat from each sensor is similar and is ap
strojnjashka [21]

Answer:

The value of the parameter is λ is 0.03692

Step-by-step explanation:

Consider the provided function.

f(x) = 0.5\lambda e^{-\lambda |x|} for −∞ < x < ∞.

It is given that standard deviation is given as 38.3 km.

Now we need to calculate the value of parameter λ.

The general formula for the probability density function of the double exponential distribution is: f(x)=\frac{e^{-|\frac{x-\mu}{\beta}|}}{2\beta}

Where μ is the location parameter and β is the scale parameter.

Compare the provided equation with the above formula we get.

\lambda=\frac{1}{\beta} and μ = 0.

Standard deviation = √2β

S.D=\sqrt{2} \beta\\\beta=\frac{38.3}{\sqrt{2}}\\\beta=27.08219

Now substitute the value of β in \lambda=\frac{1}{\beta}.

\lambda=\frac{1}{27.08219}=0.03692

Hence, the value of the parameter is λ is 0.03692

Algebra 2 <br> 50 POINTS <br> HELP
xenn [34]

Answer:

{-3, 2}U{2, 5}

Step-by-step explanation:

For an equation to be negative, it would need to be in a negative range (below the x-axis or the coordinates are negative y-values). Therefore, we can examine this question and see that the graph is negative when the function crosses the x-axis at -3 and it remains negative until you reach 2 on the x-axis.

Therefore, the first set of negative values is (-3, 2).

Secondly, applying the same logic as before, the function decreases at 2 and then touches the x-axis again at 5. Therefore, the second negative value would be (2, 5).

The negative values are {-3, 2}U{2, 5}.
