I got corrected by mreijepatmat, and this is what they said: "Let x be this number so (x+5)(x-5) =75 ===> x^2 -25 = 75 ===> x^2 =100 & x = 10."
I hope this answer helped you! If you have any further questions or concerns, feel free to ask! :)
Answer:
Yes, the event are mutually exclusive...
Step-by-step explanation:
Event are mutually exclusive if those event cannot occur at the same time. That is the definition of mutually exclusive for instance in a football match, a certain team canot score 0 and 2goals in a match, it is either he scored 2goals or zero goals... In a throw of a coin we cannot have head and tail at the same time, it is either we have a head or a tail, all the event are mutually exclusive.
Now if we have a dealer selling blue car and two doors car. Let say 20% are blue and 10% have two doors. Then, this are not mutually exclusive because we can have a car that is blue and have two doors.
Mutually exclusive events are like disjoint set in SET theory, where A intersection B intersection C is equal to empty set.
Where A n B n C= {} empty set
4/5 and 40/50 are both equivalent
Answer:
-50/6 or -25/3
Step-by-step explanation:
to isolate x, you multiply -5/2 to each side.
10/3 * -5/2
when you simplify you get
-25/3
