Answer:
V = 36 pi cm^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3 where 4 is the radius
V = 4/3 pi(3)^3
V = 36 pi cm^3
Answer:
1)Reject H_o if t> 2.998
2) t = 2.8594
3) No, conclusion about positive association in population is not reasonable
Step-by-step explanation:
To Test ![H_o : \rho = 0 vs H_1:\rho>0](https://tex.z-dn.net/?f=H_o%20%3A%20%5Crho%20%20%3D%200%20vs%20H_1%3A%5Crho%3E0)
we know that Test statics is
![t = \frac{r\sqrt{n-2}}{\sqrt{1- r^2}} \sim t_{n-2}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Br%5Csqrt%7Bn-2%7D%7D%7B%5Csqrt%7B1-%20r%5E2%7D%7D%20%5Csim%20t_%7Bn-2%7D)
1) Reject H_o if![t > t_{n-2}\alpha](https://tex.z-dn.net/?f=%20t%20%3E%20t_%7Bn-2%7D%5Calpha)
n = 9, ![\alpha = 0.010](https://tex.z-dn.net/?f=%5Calpha%20%3D%200.010)
![t_7(0.010) = 2.998](https://tex.z-dn.net/?f=t_7%280.010%29%20%3D%202.998)
Reject H_o if t> 2.998
2) ![t = \frac{r\sqrt{n-2}}{\sqrt{1- r^2}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Br%5Csqrt%7Bn-2%7D%7D%7B%5Csqrt%7B1-%20r%5E2%7D%7D)
n = 9 r = 0.734
so we have t = 2.8594
3) t = 2.8594
therefore
, hence we accept hypothesis or H_o
No, conclusion about positive association in population is not reasonable
Answer:
3 over 2
Step-by-step explanation:
<u>Simplify:</u>
- 3⁻⁴*2³*3²/2⁴*3⁻³ =
- 3⁻⁴⁺²⁻⁽⁻³⁾*2³⁻⁴ =
- 3⁻²⁺³*2⁻¹ =
- 3/2
<u>Correct answer choice:</u> the first one 3 over 2
