Alan's company rents cars to people who are at least 24 years old. which graph best represents the possible ages of people who can rent cars from alan's company?
a number line with a closed circle on 24, with shading to the left.
a number line with an open circle on 24, with shading to the left.
a number line with a closed circle on 24, with shading to the right.
a number line with an open circle on 24, with shading to the right.

  A number line with a closed circle on 24, with shading to the right.

Step-by-step explanation:

"At least 24" means 24 or more. The graph will have a closed circle at 24, because 24 is part of the solution set. The shading will extend to the right, because numbers greater than 24 are also included in the solution set.

  ⇒ closed circle at 24, shading to the right

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
