Answer:
1. always
2.never
3.sometimes
4.always
5.sometimes
6.always
Step-by-step explanation:
It is clear from the given number line, that is a negative integer and
is a positive integer.
1. It is always true because addition is always commutative property.
2. It is never positive because product of two different sign is always negative.
3.dividing two integer with unlike sign may result in any integer
4.when a positive quantity is reduced from a negative quantity, the result is always negative.
5.division of two unlike integers may result the same,if they both have the same value
6.If an opposite of a positive integer is added to that positive integer itself, the result is is always 0.
Answer:
x = 38°
Step-by-step explanation:
An external angle is equal to the sum of the opposite internal angles of a triangle. Either of the internal angles at the base can be found as the supllement of its external angle.
∠OLM = 180° -134° = 46°
Then
... x +46° = 84°
... x = 38° . . . . . subtract 46°
Answer:
(a) 1/3
(b) 1/15
Step-by-step explanation:
(a)Let X denote the waiting time in minutes. It is given that X follows a uniform distribution, and since the variable being measured is time, we assume it to be a continuous uniform distribution.
Now
.
Jack or Rose arriving first is equally likely, therefore the probability of Jack waiting is just the half of the above obtained probability i.e
(b)Using the formula for the expectation of a uniform continuous distribution,
