The total age of yvonne and samuel is 40 yvonne is 4 years older than samuel find their ages.

Yvonne is 22

Samuel is 18

Step-by-step explanation:

y is age of yvone, s is age of samuel

Write 2 equations:

y + s = 40

y = s + 4

Substitute (s + 4) into y in the first equation:

s + 4 + s = 40

Solve:

2s + 4 = 40

2s = 36

s = 18

Substitute 18 for s in either equation:

y + 18 = 40

Solve:

y = 22

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
