A four-person congressional committee is to be formed consisting of two senators and two representatives. The senators are to be chosen from W, X, Y, and Z; the representatives are to be chosen from P, Q, R, and S. The committee will be chosen by the vice-president subject to the following conditions:

a. S will not serve on the committee unless X does.
b. Y will not serve on a committee with Q.
c. The vice-president has decided that Y or Z must be included, but neither Y nor Z is willing to serve with the other. 25.
d. If the vice-president chooses S to be on the committee, which of the following CANNOT be on the committee

W

Step-by-step explanation:

The conditions are:

If representative S serves on the committee, then senator X must also serve on the committee (1st condition).  The other senator must be either Y or Z (3rd condition).  So no matter who the vice-president chooses, senator W cannot be on the committee.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
