Answer:
The number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.
Step-by-step explanation:
The (1 - <em>α</em>) % confidence interval for population mean is:
The margin of error for this interval is:
The information provided is:
<em>σ</em> = $569
MOE = $140
Confidence level = 95%
<em>α</em> = 5%
Compute the critical value of <em>z</em> for <em>α</em> = 5% as follows:
*Use a <em>z</em>-table.
Compute the sample size required as follows:
Thus, the number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.
Answer
203m^2
Step by Step:
Well to find the total SA of the following pyramid we need to find the area of one triangle and multiply and the square.
so let’s start with the square the square is a 7 by 7 so it’s area is 49 and the triangle has a height of 11 and a base of 7 so using to formula b*h / 2 we get 38.5 after dividing 77 by 2.
So now to get the areas of all 4 triangles we do 38.5 * 4 which is 154.
And now we add 154+49 = 203m^2.
