Answer:

a) (i) A∪B are 8, 9, 14, 15, 16, 17

(ii) A ∩ B are 14 and 17

b) The probability that a number chosen at random is in the set A' is 0.7

Step-by-step explanation:

a) (i) The numbers that are in the set A∪B are given as follows;

A∪B = {x: x ∈ A or x ∈ B}

A∪B is the set of all elements "x" such that "x" is a member of A or B

Therefore, A∪B = (8, 9, 14, 15, 16, 17)

(ii) A intersection B, written as , A∩B), is the set of elements belonging to both set A and set B

A∩B  = {x: x ∈ A and x ∈ B}

Therefore;

A ∩ B = 14 and 17

b) The set A' which is the complement of A are the elements in the universe which are not in A

The number of elements in the Venn diagram = 10 (numbers)

The number of elements in the set A' = 7

The probability that a number chosen at random is in the set A', P(A') is given as follows;

P(A') = (The number of elements in the set A')/(The number of elements in the Venn diagram)

∴ P(A') = 7/10 = 0.7

Answer:

i)17,14,8,16,15

ii)14,8

The probability that the number is in set B,giving your answer as a decimal is 0.6.

i)is the numbers in A and B all of it even the numbers which are in both (middle circle)

ii)numbers in the middle circle.

Which table represents a linear function?​
Romashka-Z-Leto [24]

Answer:

1st one

Step-by-step explanation:

Since the x's for each one are going up by the same number, you are looking for a column of y's to either by going up by the same number or down by the same number.

The first table has a column of y's that look like this:  1/2 , 1 , 1  1/2,  2  

This is actually going up for 1/2 each time.

This table shows a linear function.
