If a study suffers from confounding, what is true? The variable of interest is not known.

The researchers are confused by the experiment.

The effects of different variables are mixed, so the researcher cannot determine the effects of the variable of interest.

The variable of interest has no effect on the experiment at all.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

answer: f = 32.2m

step-by-step explanation: that is the answer

a) 32pie square meters

step-by-step explanation:

if x = 1, then the answer is 3.5
