Another fraction that's not on there that is correct is 8/10
(1 point) Consider the universal set U={1,2,3,4,5,6,7,8,9,10}, define the set A be the even numbers, the set B be the odd number

Answer:
a) AUC = {2,4,6,8,10}
b) BnC = {}
c) AnB = {}
d) B-C = B = {1,3,5,7,9}
Step-by-step explanation:
The set A is the even numbers, those that are divisible by two.
So A = {2,4,6,8,10}
B is the odd numbe.rs. An odd number is a number that is not divisible by two.
So B = {1,3,5,7,9}.
C = {4,5,6}, as the problem states
a) The union of sets is a set containing all elements that are in at least one of the sets. So the union of A and C is a set that contains all elements that are in at least one of A or C.
So AUC = {2,4,6,8,10}.
b) The intersection of two sets consists of all elements that in both sets. So, the intersection of B and C is the set that contains all elements that are in both B and C.
There are no elements that are in both B and C, so the intersection is an empty set
BnC = {}
c) Same explanation as b), there are no elements that are in both A and B, so another empty set.
AnB = {}
d) The difference of sets B and C consists of all elements that are in B and not in C. We already have in b) that BnC = {}, so:
B-C = B = {1,3,5,7,9}
Angle K is 19° because 180-161 = 19.
And Z = 7 because 19 + 18z + 3 + 5z -3 =180
Then you simplify it to 23z + 19 = 180
Simplify more to get 161/23 = 7, so Z = 7
Relationship between distance and time is A. d = 0.12m
Step-by-step explanation:
For an object moving in uniform motion (=constant velocity), the relationship between distance covered and time taken is given by
where
d is the distance
v is the velocity
t is the time
Therefore, in order to find the relationship between distance and time, we have to find the velocity of the train.
This can be done by using the data of the table: in fact, the velocity is the ratio between the distance covered and the time taken to cover that distance.
Therefore, if we take for instance the last point of the table:
d = 2.4 miles (distance covered)
t = 20 minutes (time taken)
So the velocity is
And therefore, the relationship between distance and time is
(where m is the time in minutes)

Answer:
Step-by-step explanation:
Angles 3 and 6 are consecutive interior angles
<u>As per definition, consecutive internal angles add to 180°</u>
- m∠3 = 67° ⇒
- m∠6 = 180° - 67° = 113°
