Use the following formula valid fo every polyhedron.
v-e+f=2
<span>
Search for Euler characteristic, or Euler-Poicare characteristic for more depth about this formula </span>
v= number of vertices
e=number of edges
f=number of faces
<span>You get v=13

Answer:
A) 2/10 or 20%
B) 3/10 or 30%
Step-by-step explanation:
There are 10 ice pops.
10 is going to be your denominator
Your numerator is going to be whatever amount of ice pops is.
After finding your fraction, divide the numerator by the denominator.
Lastly turn your decimal into a fraction.
2/10=0.2=20%
Hope I helped you.
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:
15x-45+7
Step-by-step explanation:
You would add the 10x and the 5x im pretty sure that would simplify it
