Answer:
<h2>The total surface area of the box is 224 square inches.</h2>Step-by-step explanation:
The box pattern is shown in the image attached.
The total surface is the sum of the area of each section of the figure, which is formed by 4 equal rectangles and 2 equal squares. Rectangles have dimensions of 12 inches by 4 inches, and squares have 4 inches per side.
So, the total surface would be
Therefore, the total surface area of the box is 224 square inches.
The area formula for a parallelogram is the same as it is for a square or a rectangle. It's A = b*h. They give you the area and the height, and x is part of the radicand for the base. Set it up like this: 
. Divide both sides by 7 to get 
. Now, the opposite of a square root is squaring, so let's undo that square root by squaring. But because this is an equation, if you square the right you also have to square the left. 
. Squaring that square root undoes the square root, so now what we have is 36 = 6 + x, and 30 = x. There you go!
Answer:
Given:
Mean, u = 2100
A golf magazine reports the mean gain to be $2100, while the teaching professional believes the average gain is not $2100.
Here the null and alternative hypotheses would be:
Null hypothesis:
H0: u = 2100
Alternative hypothesis:
Ha: u ≠ 2100
b) Here, given the level of significance, as 0.10. This means that:
The probability that the null hypothesis H0 is rejected when average gain is $2100 is 0.10
