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

<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
Hello, I’m not super sure about the last part but to get 1 divide 20 by 20 and then from 1 multiply by 12 to get 12. I hope this helps :)
Answer:
Volume= base*height*length; Volume= 24*9*24; Volume= 5,184 square feet
Step-by-step explanation:
The lenghth of the square is 24 feet which makes the base 24 since it is a square. So, you just have to multiply 24*24*9 to get the total volume.
