a square is a quadrilateral
If it is equal on all side divide 1080 by how many sides there are otherwise more info pls
The answer is:
.
____________________________________________Explanation:____________________________________________We have: " 6⁻¹ * (-2)³ * (-4)⁻² = ? " ;
_______________________________________Note: "6⁻¹ =

=

" .
Note the following property of exponents:
____________________________________ a⁻ˣ =

; {x ≠ 0}.
____________________________________________Note: (-2)³ = (-2)*(-2)*(-2) = 4*(-2) = -8 .
_______________________________________Note: (-4)⁻² =

;
=

;
=

;
____________________________________So; we have:
_____________________________________6⁻¹ * (-2)³ * (-4)⁻² ;
=

;
→ Cancel out the "8" in the "numerator" (to a "1") ; and the "16" in the number (and change to a "2"); since: {"16÷8 = 2" ; and since: "{8÷8=1"} ;
→and we have:

;
=

.

Answer:
D is the correct option
Step-by-step explanation:
The roulette can land in any possibly slot and their are 38slots
i.e the total possible event is 38
Green slot = 2
Red slot =18
Black slot =18
P(G)=2/38 =1/19
P(R)=18/38=9/19
P(B)=18/38=9/19.
The roulette will be spun twice and they are independent i.e. the occurrence of one event does not affect the occurrence of the other.
We are looking for the probability of red first and probability of black
P(R n B)=P(R)P(B), since they are independent
P(R n B)=9/19×9/19
P(R n B)= 0.2244
D is the correct option
