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

MO bisects angle LMO = 6x-22, and angle NMO = 2x + 34. solve for x and find angle LMN.
myrzilka [38]

Step by step explanation

1) 6x-22=2x+34  both the angles are equal to each other because when you biset an angle you break it up into 2 equal parts

2) 4x=56 Collect like integers

3) x=14 Divide both sides by 4 to get x by itself

The answer is x=14
