What is the value of z, rounded to the nearest tenth? use the law of sines to find the answer.
DanielleElmas [232]
We can change the law of sines a little bit to match our problem.

\sf\dfrac{sin(X)}{x}=\dfrac{sin(Y)}{y}=\dfrac{sin(Z)}{z}

We know what angle Y is and what side y is, so let's use that along with angle Z and side z:

\sf\dfrac{sin(Y)}{y}=\dfrac{sin(Z)}{z}

Plug in what we know:

\sf\dfrac{sin(51)}{2.6}=\dfrac{sin(76)}{z}

Multiply 'z' to both sides:

\sf\dfrac{sin(51)}{2.6}z=sin(76)

Divide sin(51)/2.6 to both sides:

\sf z=\dfrac{sin(76)(2.6)}{sin(51)}

Plug it into your calculator.

\boxed{\sf z\approx 3.2}

A school psychologist recruits 600 second-grade students and randomly divides them into two groups.

Group 1 is taught by means of the new method, while Group 2 is taught via traditional methods.

We have to find the response variable. A response variable is the outcome variable or dependent variable in the experiment.

Here this is - The scores on the achievement tests of both group 1 and group 2.
