Answer:

The answer to your question is: x = - 102

Step-by-step explanation:

                                          - \frac{x}{6}  + 1 = 18

                                          - \frac{x}{6} = 18 - 1

                                          - \frac{x}{6}  = 17

                                          -x = 17 x 6

                                         -x = 102

                                          x = -102

In a recent year, grade 8 Washington State public school students taking a mathematics assessment test had a mean score of 281 w
sweet-ann [11.9K]

Answer:

The probability that the mean test score is greater than 290

P(X⁻ > 290 ) = 0.0217

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Mean of the Population (μ) = 281

Standard deviation of the Population = 34.4

Let 'X' be a random variable in Normal distribution

Given X = 290

Z = \frac{x -mean}{\frac{S.D}{\sqrt{n} } } = \frac{290-281}{4.44} = 2.027

<u><em>Step(ii):-</em></u>

<em> The probability that the mean test score is greater than 290</em>

P(X⁻ > 290 ) = P( Z > 2.027)

                    = 0.5 - A ( 2.027)

                   = 0.5 - 0.4783

                   = 0.0217

The probability that the mean test score is greater than 290

P(X⁻ > 290 ) = 0.0217
