Answer:

x = 1

Step-by-step explanation:

Oh, this is one of those incredibly cool circle theorems! You might like this page:

For two secants that intersect at a point outside the circle, the product

(segment outside the circle)(whole secant) is the same for both secants!

What's the length of the entire secant that has x's on it? 6x + 8x = 14x.

What's the length of the entire secant that has 9 and 7 on it? 9 + 7 = 16

$8x(14x) = (7)(16) \\ 112x^2 = 112 \\ x^2=1 \\ x=1$

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:

Interacting variables are not mapped accurately. The additional variables as the health status of the volunteers, eating and fitness habits are not considered in the consideration. This results in a in complete validation.
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.
