A chi-square test is a statistical test used to test the relationship between categorical variables. It is used to determine the difference between the expected data and the observed data is due to chance.

Chi squared = $\frac{(O_{i} - E_{i} )^{2} }{E_{i} }$

Where:

$O_{i}$ = observed value
$E_{i}$ = expected value.

The researcher is interested in knowing if the response to lowering the legal age for drinking alochol (observed value)) varies by gender (expected value). Thus, a chi-square test would be used.

n this triangle, what is the value of x? Enter your answer, rounded to the nearest tenth, in the box. x = cm A right triangle wi

nikklg [1K]

See the attached picture to better understand the problem

we know that
in the right triangle ABC
sin 63°=AB/BC
AB is the opposite side angle 63-----> x cm
BC is the hypotenuse-----> 85 cm
AB=BC*sin 63°-----> AB=85*sin 63-----> AB=75.736 cm
AB=75.8 cm

the answer is
the value of x is 75.8 cm
