There are 170 patients total and 100 out of 170 are given placebo and 70 are not so there is a 70/170 chance of not getting it but if you want a decimal then you divide the numerator 70 by the denominator 170 which is 0.41176... then you have to move the decimal point over to the right by two places so its 41.1176...% you can also round it to 41.12%

Arial says that, for any pair of linear relations, if the coefficients of the y-terms are equal and the coefficients of the x-te
wel

Answer:

<h3>a. Give an example for which Arial's claim is true.</h3>

If linear relations have equal coefficient about the independent variable, then those linear relations are parallel. For example, y=3x+4 and y=3x-5.

Notice that the coefficient of the dependent variable must be also equal, otherwise it would change the slope of the expression and they wouldn't be parallel.

<h3>b. Give an example for which Arial's claim is false. </h3>

The statement is not false.

<h3>c. Suggest an improvement to Arial's claim.</h3>

An improvemente would be that the constant term no need to be equal too, between linear relations, because they can be at "differecent heights", sort of speak.
