X + 2 = 5x + 26<br><br> Please help

kkurt [141]

$x+2=5x+26$

Move all the x's to one side of the equation. This is a step necessary to solve this equation.

Subtract both sides by x.

$x+2-x=5x+26-x$
$2=4x+26$

Flip equation. We always want to have the variable written on the left side.

$4x+26=2$

Subtract both sides by 26.

$4x+26-26=2-26$
$4x=-24$

Divide both sides by 4 to finish this off.

$x=-6$

That's your answer. Have an awesome day! :)

A random sample of 121 bottles of cologne showed an average content of 4 ounces. It is known that the standard deviation of the

pychu [463]

Answer:

Standard error of the mean parameter the average content of colognes

S.E = 0.02 ounces

Step-by-step explanation:

<u><em>Explanation</em></u><em>:-</em>

<em>Size of random sample 'n' = 121 bottles</em>

<em>mean of the sample </em> $x^{-} = 4$ ounces

<em>Standard deviation of Population</em>

<em> σ = 0.22</em>

<em>Standard error of the mean parameter the average content of colognes</em>

<em> </em> $S.E = \frac{S.D}{\sqrt{n} }$ <em></em>

<em> </em> $S.E = \frac{S.D}{\sqrt{n} } = \frac{0.22}{\sqrt{121} }$ <em></em>

S.E = 0.02

<u><em>Final answer:-</em></u>

<em> Standard error of the mean parameter the average content of colognes</em>

<em> S.E = 0.02 ounces </em>

Use Tornados data and find two months (month X and month Y) for which we have the SECOND strongest NEGATIVE correlation. Create

viva [34]

Answer:

None of the statements is true. that is (e) None of the choices.

Step-by-step explanation:

Because if we go by the definition above that that Month X and month Y have the " strongest NEGATIVE correlation" then we can see clearly see that the option is not included.

Negative Correlation: this is the exact relationship between two variables whereby if one variable increases then the other variable decreases and vice versa.

Hence by this we are suppose to conclude that if we observe more tornadoes in month X then we will observe less tornadoes in Month Y.
