Find the indicated intersection or union {q, s, u, v, w, x, y, z} ∩ {q, s, y, z}

answer: 5/2     2 1/2

step-by-step explanation:

5/2              

5 goes into 2 two times so its 2 and 1/2

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
