Answer:

x=12, DO=45O, G=45, DG=90

Step-by-step explanation:

Mid point means both lenghts are equal

4x-3=2x+21

2x=24

X=12

-----------------

1)4(12)-3=48-3=45

2)2(12)+21=24+21=45

-----------------------------

DO=45

OG=45

DG=90

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>
