Answer:
576
Step-by-step explanation:
4 feet^2 = 2 feet*2 feet = 24 inch * 24 inch. 24*24 = 576.
3 1/9 or 3.11 because you get a remainder of 1.
Answer:
- 0.9503 ; r is not statistically significant ; 0.9031
Step-by-step explanation:
Given the following :
Age (X) :
37
41
57
65
73
Bone density (Y)
355
345
340
315
310
Using the pearson R value calculator :
The r value of the data % - 0.9503.
This value depicts a very strong negative correlation between age and density of bone.
Using the pearson R calculator to obtain the P- value, the P value obtained is .01332 and hence the r is not significant at P < 0.01.
The Coefficient of determination R^2 can be obtained by getting the square value of R
R^2 = - 0.9503^2
R^2 = 0.90307009
R^2 = 0.9031
Answer:
B
Step-by-step explanation:
Using the expansion
tan(x - y) = , then
tan(x - )
=
note that tan( -) = - tan() = -
=
= → B
