Thank you for letting me do this math i needed it lol
Answer:
mean = 254.6
median = 120
mode = 60
midrange = 958
For average data sets i prefer by finding the mean
Step-by-step explanation:
mean :
(98+120+493+206+73+102+183+870+76+60+60+112+147+1018+201) ÷ 15 = 254.6
median : 60 60 73 76 98 102 112 120 147 183 201 206 493 870 1018
find the middle number
= 120
mode :
number that is more than one
= 60
midrange :
highest number - smallest number
= 1018 - 60
= 958
Answer:
Adult ticket = $11
Children ticket = $9
Step-by-step explanation:
Let the price of adult tickets be x and let the price of children's ticket be y
For the first day, the equation of sales can be put as
3x + 12y = 141..........1
For the second day, the equation of sales can be put as:
13x + 6y = 197............2
We then take these two equations together and solve simultaneously.
3x + 12y = 141.......1
13x + 6y = 197........2
Solving by elimination method, we Multiply through equation 1 by 13 and multiply through equation 2 by 3.
39x + 156y = 1833.........3
39x + 18y = 591..............4
Then subtract equation 4 from equation 3
138y =1242
y = 9
Substitute "y=9" into equation 1 to find x
3x + 12(9) =141
3x + 108 = 141
3x = 141 - 108
3x = 33
x = 11
Hence,
Price of adult ticket = $11
Price of children ticket = $9
