Answer:
The claim made by the researcher lacks the validity on basis of reasons as indicated in the explanation.
Step-by-step explanation:
The claim made by the researcher is not valid on basis of following reasons:

- The placebo effect is not catered accordingly. As the half of the volunteers are taking nothing, this is not the direct influence of the placebo and thus double-blinded testing for placebo effect is to be ensured in future experiments.
- The environmental effects are not considered as the effect under study is dependent on the environmental effects, thus the claim is biased and the generalization is not valid.
Answer:
About 11494.04
Step-by-step explanation:
There is no sphere shown above but I can still get you the answer:
The formula for the volume of a sphere is 
π*r³
Putting in the radius, we get:
*π*14³=
*π*2744=
*π=
3658.66*π≈11494.04
Answer:
if you turn it sideways it looks like an acute so i think it will be 60* or 61* i am not sure

Hope this helps
Answer:
15.9 centimeters
Step-by-step explanation:
the information we have is:
Perimeter: 
Number of sides of the polygon: 
since each side has equal length, we can use the following equation to find the measure of one side of the polygon, the equation for perimeter:
where n is the number of sides and 
is the length of each side.
So we clear for and we get:
and subtituting the known values:
each side is 15.6 centimeters long
