Travka [436]

Answer:

maximum --> 62

median --> 46.5

upper quartile --> 60

lower quartile --> 37

minimum --> 32

Step-by-step explanation:

Forgive me on the explanation as I'm a bit rusty on these types of problems.

First, we need to put the set of numbers in order -->

from: 34, 37, 39, 32, 48, 45, 53, 62, 58, 61, 60, 41 -->

to: 32, 34, 37, 39, 41, 45, 48, 53, 58, 60, 61, 62

maximum = biggest number => thus, 62

median = middle number in a sense => (45+48)/2 => thus, 46.5

upper quartile = median over the median => thus, 60

lower quartile = median under the median => thus, 37

minimum = lowest number => thus, 32

And there we have our 5 answers.

Members of a soccer team raised $2158 to go to a tournament. They rented a bus for $1130.50 and budgeted $68.50 per player for m

Over [174]

Answer: 15

Step-by-step explanation:

Let x = the number of players the team can bring to the tournament.

Given: Soccer team raised $2158 for tournament.

Bus rent = $1130.50 and budget per player for meals = $68.50

Total cost of tournament = Bus rent + (budget per player for meals) ( number of players the team)

$2158=1130.50+68.50x\\\\\Rightarrow\ 68.50x=2158-1130.50\\\\\Rightarrow\ 68.50x=1027.5\\\\\Rightarrow\ x=\dfrac{1027.5}{68.5}\\\\\Rightarrow\ x=15$

Hence, the number of players the team can bring to the tournament = 15
