Answer:
Step-by-step explanation:
In the model
Log (salary) = B0 + B1LSAT +B2GPA +B3log(libvol) +B4log(cost)+B5 rank+u
The hypothesis that rank has no effect on log (salary) is H0:B5 = 0. The estimated equation (now with standard errors) is
Log (salary) = 8.34 + .0047 LSAT + .248 GPA + .095 log(libvol)
(0.53) (.0040) (.090) (.033)
+ .038 log(cost) – .0033 rank
(.032) (.0003)
n = 136, R2 = .842.
The t statistic on rank is –11(i.e. 0.0033/0.0003), which is very significant. If rank decreases by 10 (which is a move up for a law school), median starting salary is predicted to increase by about 3.3%.
(ii) LSAT is not statistically significant (t statistic ≈1.18) but GPA is very significance (t statistic ≈2.76). The test for joint significance is moot given that GPA is so significant, but for completeness the F statistic is about 9.95 (with 2 and 130 df) and p-value ≈.0001.
We can find the surface area of the pyramid as
![A = l*w+l*\sqrt{(\frac{w}{2} )^{2} +h^{2} }+w*\sqrt{(\frac{l}{2} )^{2} +h^{2}}](https://tex.z-dn.net/?f=A%20%3D%20l%2Aw%2Bl%2A%5Csqrt%7B%28%5Cfrac%7Bw%7D%7B2%7D%20%29%5E%7B2%7D%20%2Bh%5E%7B2%7D%20%7D%2Bw%2A%5Csqrt%7B%28%5Cfrac%7Bl%7D%7B2%7D%20%29%5E%7B2%7D%20%2Bh%5E%7B2%7D%7D)
here , because the base is squre so
![l = w = 8](https://tex.z-dn.net/?f=l%20%3D%20w%20%3D%208)
![h = 5](https://tex.z-dn.net/?f=h%20%3D%205)
By putting the values of l,w and h
we get
![A = 8*8+8*\sqrt{(\frac{8}{2} )^{2} +5^{2} }+8*\sqrt{(\frac{8}{2} )^{2} +5^{2}}](https://tex.z-dn.net/?f=A%20%3D%208%2A8%2B8%2A%5Csqrt%7B%28%5Cfrac%7B8%7D%7B2%7D%20%29%5E%7B2%7D%20%2B5%5E%7B2%7D%20%7D%2B8%2A%5Csqrt%7B%28%5Cfrac%7B8%7D%7B2%7D%20%29%5E%7B2%7D%20%2B5%5E%7B2%7D%7D)
![A = 64+8*\sqrt{16 +25 }+8*\sqrt{16 +25}](https://tex.z-dn.net/?f=A%20%3D%2064%2B8%2A%5Csqrt%7B16%20%2B25%20%7D%2B8%2A%5Csqrt%7B16%20%2B25%7D)
![A = 64+(8*\sqrt{41) +(8*\sqrt{41})](https://tex.z-dn.net/?f=A%20%3D%2064%2B%288%2A%5Csqrt%7B41%29%20%2B%288%2A%5Csqrt%7B41%7D%29)
![A = 64+51.2+51.2](https://tex.z-dn.net/?f=A%20%3D%2064%2B51.2%2B51.2)
![A = 166.4](https://tex.z-dn.net/?f=A%20%3D%20166.4)
Answer:
The angle = 144 degrees.
Step-by-step explanation:
Look at it this way (it is a proportion question)
30 people would require a pie chart made of a full circle (360 degrees)
12 people would require x part of the pie chart.
30/360 = 12 / x Cross multiply
30x = 360 * 12 Simplify the right
30x = 4320 Divide by 30
30x/30 = 4320/20
x = 144 Answer
