In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25
in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1
in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.
5+ (-5) = 0
5- (-5) = 10

Answer: 0.57
Step-by-step explanation:
Given : The speed of cars on a stretch of road is normally distributed .
Population Mean =
Standard deviation :
Let x be the random variable that represents the speed of cars on a stretch of road .
z-score :
For x= 50.
By using the standard normal distribution table ,
The probability that a randomly selected car is violating the speed limit of 50 miles per hour :-
