1 answer:
Here is the completed table:
Has pet Has no pet Total
7th grade 102 48 150
8th grade 107 68 175
Total 209 116 325
<h3>What is a two-way table?</h3>A two way table is used to show the frequency of two categorical variables. Information are usually presented in rows and columns.
- The 7th grade students that have no pets = 150 - 102 = 48
- The 8th grade students that have pets = 175 - 68 = 107
- Total students that have pets = 102 + 107 = 209
- Total students that have no pets = 48 + 68 = 116
- Total = 209 + 116 = 325

Answer:
Follows are the solution to the given point:
Step-by-step explanation:
In point a:
¬∃y∃xP (x, y)
∀x∀y(>P(x,y))
In point b:
¬∀x∃yP (x, y)
∃x∀y ¬P(x,y)
In point c:
¬∃y(Q(y) ∧ ∀x¬R(x, y)) ∀y(> Q(y) V ∀ ¬ (¬R(x,y)))
∀y(¬Q(Y)) V ∃xR(x,y) )
In point d:
¬∃y(∃xR(x, y) ∨ ∀xS(x, y))
∀y(∀x>R(x,y)) ∃x>s(x,y))
In point e:
¬∃y(∀x∃zT (x, y, z) ∨ ∃x∀zU (x, y, z))
∀y(∃x ∀z)>T(x,y,z) ∀x ∃z> V (x,y,z))
