tatiyna

Answer:

Mean = $229.32

Median = $231.15

Mode = $268.4

Step-by-step explanation:

Mean = the average.

The average is the sum of variables divided by the number of variables.

x = each variable

N = number of variables = 11

Average = (Σx)/N = (236.09 + 204.43 + 253.82 + 268.4 + 231.15 + 205.7 + 262.18 + 162.77 + 268.4 + 224.45 + 205.17)/11

Mean = 2522.56/11 = $229.32

b) Median is the value that falls at the middle of the data set if all the variables are arranged in ascending or descending order.

So, to find the Median, we first arrange the variables in ascending order.

162.77

204.43

205.17

205.70

224.45

231.15

236.09

253.82

262.18

268.4

268.4

Since there are 11 variables, the Median is the number that falls at the middle of the distribution, that is, at the sixth position.

Median = $231.15

c) Mode is the number that appears the most in a distribution.

In this distribution, only 268.4 appears more than once.

Hence, the more is $268.4

A.It will stay the same
DanielleElmas [232]

Answer:

B

Step-by-step explanation:

Let's arrange the data set in increasing order.

We have 19, 27, 27, 33, 45, 53. The median is (27 + 33) / 2 = 30.

The new set is 19, 27, 27, 33, 45, 53, 90. The new median is 33.

Since 33 - 30 = 3 the answer is B.

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>
