Answer:

B. $\frac{1}{x^2y^7}$

Step-by-step explanation:

Given:

$(x^3y^{-2}z)(x^{-5}y^{-5}z^{-1})$

Hence Solving the given expression we get;

By Law of Indices which states;

$(a^xb^yc^z)(a^pb^qc^r) = a^{x+p}b^{y+q}c^{z+r}$

Hence we get;

$x^{3+(-5)}y^{(-2)+(-5)}z^{1+(-1)}\\\\x^{3-5}y^{-2-5}z^{1-1}\\\\x^{-2}y^{-7}$

Also We know that

$a^{-6} =\frac{1}{a^6}$

So,

$\frac{1}{x^2y^7}$

The Venn diagram represents the results of a survey that asked participants whether they would want a bird or a fish as a pet.

alexandr1967 [171]

I got the answer right, I just took the test: (going from left to right)
Fish+Bird= 6
Bird+Not fish= 8
Total= 14

Fish+Not bird= 19
Not fish+Not bird= 22
Total= 41

(Now going down the column)
Fish total= 25
Not fish total= 30

Total+Total= 55
