Answer:
3/5
Step-by-step explanation:
10 total - 4 = 6
6/10 = 3/5
Based on the distance travelled and the time taken, the speed of the train was <u>150 km/h</u>
Speed can be calculated by the formula:
<em>= Distance / Time </em>
Distance = 600 km
Time = 4 hours
Solving will give:
= 600 / 4
= 150 km/ h
In conclusion, the train was going at 150 km/h

Answer:
Step-by-step explanation:
Given:
Universal set is all positive integers {1,2,3...}
Set A is the set of all positive <u>ODD</u> integers {1,3,5,7...}
The question asks us to find , which is the <em>complement of set A</em>. The complement of a set refers to elements NOT in that set. Hence, complement of A should be all the elements NOT in A but in Universal Set, U.
It is clear from the question that set A houses all the odd positive numbers, so complement of A will have all the even positive numbers. Last choice is the correct one.
ANSWER: "{x|x ∈ U and is an even positive integer}"
