kondaur [170]

Answer:

'A' is true; theoretically, 50% of the data items reside between the first and third quartiles (40 and 67.5)

Step-by-step explanation:

Range is 84-28 which is 56

Median is 51

1.5 x Interquartile Range (IQR) = 1.5(67.5-40) which equals 41.25

Q1 is 40

Q1 - IQR = -1.25

Low outliers are below -1.25 - 41.25; there are not data items below -42

inn [45]

Answer:

Kenny will get $16 change from $100 if he buys a book of 8.


Step-by-step explanation:

Given cost of each ticket of the dinosaurs now exhibit = $10.50.

Total number of tickets = 8 tickets.

Total amount Kenny has to buy tickets = $100.

He need to buy only 8 tickets.

Total cost of 8 tickets = cost of one ticket × total number of tickets

                                    = 10.50 × 8

                                   =  $84.

Therefore cost of all 8 tickets is $84.

Kenny would left money = 100 - 84 = $16.

<h3>Therefore, Kenny will get $16 change from $100 if he buys a book of 8.</h3>
