Answer:
Step-by-step explanation:
4. (6^10)^-7 is when the exponents should be multiplied
answer is B
5. (7^3)^-2 = (7^-6)
1/7^6 = 1/(7x7x7x7x7x7)
answer is A
2. 11^-4/11^8= 1/11^(8+4) = 1/11^12
answer is A
3. (2^5/3^2)^4= 2^20/3^8
answer is A

13. 3 root 3
14. 5 root 2
15. 7/2 root 2
16. 3/2 root 2
17. 7.5 root 3
19. bc is squared root 37
20. 32 + 32 root 3
Answer: D. .400
Step-by-step explanation:
Given : In a multiple regression model involving 44 observations, the following estimated regression equation was obtained.

For this model,
Regression sum of squares =SSR = 600
and Sum of squares due to error =SSE = 400.
Total sum of squares = SST= SSR+SSE
SST= 600+400=1000
The multiple coefficient of determination is given by :-

Substitute values , we get


Thus, the multiple coefficient of determination for the above model is 
Hence, the correct answer is D. .400.
