The surface area 3 times greater than the area.
6 * 2 gives the area
the surface area is by multiplying area by 3.
this means that the surface area is 3x bigger than area.
Answer:
Minimum - 8.1 inches
Maximum - 8.35 inches
Step-by-step explanation:
The specifications for manufacturing a steel rod stipulate that the length must be 8.225 ± 0.125 inches.
This means that the minimum length must not be 0.125 inches less than 8.225 inches and the maximum length must not be 0.125 inches greater than 8.225 inches.
The minimum length is therefore:
8.225 - 0.125 = 8.1 inches
The maximum length is therefore:
8.225 + 0.125 = 8.35 inches

To find whether there is an association between these two let us find the correlation coefficient between these two variables.
r=-0.1975
Since |r|<0.5, correlation is weak.
Let us test the hypothesis r =0
H0:r=0
Ha:r not equals 0
Test statistic = ![\frac{r\sqrt{n-2} }{\sqrt{1-r^2} } \\=\frac{-0.1975\sqrt{11-2} }{\sqrt{1-0.1975^2} }\\=\frac{-0.5625}{{0.9803} } \\=-0.5738](https://tex.z-dn.net/?f=%5Cfrac%7Br%5Csqrt%7Bn-2%7D%20%7D%7B%5Csqrt%7B1-r%5E2%7D%20%7D%20%5C%5C%3D%5Cfrac%7B-0.1975%5Csqrt%7B11-2%7D%20%7D%7B%5Csqrt%7B1-0.1975%5E2%7D%20%7D%5C%5C%3D%5Cfrac%7B-0.5625%7D%7B%7B0.9803%7D%20%7D%20%5C%5C%3D-0.5738)
p =0.298
Since p value >0.10, at 90% significance level we accept that there is no association.
X=8-y
2(8-y)=10
16-2y=10
-2y=10-16
-2y=-6
y=3
x+3=8
x=8-3
x=5
(5,3) is the answer :)
I believe the equation should be set up like this: 85 + 5x + 5x + 5x - 10 + 5x + 5 = 540. Don't forget to combine like terms! Please let me know by sending me a message if you need any more help :)
