Answer: 232 in.^2

Step-by-step explanation:

Simply imagine the net as an unfolded box. You are calculating the surface area of that box.

First, calculate the value of the large rectangle up top. 10 * 8 = 80.

Because there are 2 equally large rectangles, 80 * 2 = 160.

Second, calculate the value of the small rectangle between the two large ones. It shares a side with one of the large rectangles, so to get the area of the rectangle, simply calculate 2 * 10 = 20. There is another rectangle of equal size, 20 * 2 = 40.

Currently, we have a total of 160 + 40 = 200 in.^2 of surface area.

Finally, to get the value of the small rectangles on the sides, multiply 8 * 2 which equals 16. There is another side the same size as this one, so 16 * 2 = 32.

To calculate final surface area, simply add 32 to 200 which equals a final total of 232 in.^2.

Answer:

232 square inches

10(8) = 80 x 2 = 160

2(10) = 20 x 2 = 40

8(2) = 16 x 2 = 32

160 + 40 + 32 = 232

How many times does the line y=-1 touch the graph? (Ensure to draw your line on the graph)​
wlad13 [49]

Answer:

twice

Step-by-step explanation:

y = - 1 is a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of - 1

Drawing this line on the graph, from (0, - 1 ) we can see that it will intersect the graph at 2 places between (0, 0 ) and (2, - 2 ) and between (2, - 2 ) and (4, 0 )

How do i solve this by using substitution? y=4x-9y=x-3
noname [10]
Y = 4x -9
y = x-3
Replace the "y" in above equation by x-3
x - 3 = 4x - 9
-3x = -6
x = 2
Then replace x = 2 to the beneth
y = 2 - 3 = -1

Answer:

The 95% confidence interval   81.852  <  \mu <  280.098

Step-by-step explanation:

From the question we are told that

   The  sample mean is  \= x  =  180.975

   The standard deviation is  \sigma  =  143.042

   The sample size is n = 8

Given that the confidence level is  95%  then the level of significance is  

    \alpha =( 100- 95) \%

=>  \alpha =0.05    

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the margin of error is mathematically represented as  

      E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }

=>  E = 1.96 *  \frac{ 143.042 }{\sqrt{8} }

=>  E = 99.123

Generally 95% confidence interval is mathematically represented as  

      \= x -E <  \mu <  \=x  +E

=>    180.975 -99.123 <  p <  180.975 +99.123

=>    81.852  <  \mu <  280.098
