Answer:

Range is 18.

Step-by-step explanation:

Range can be calculated by subtracting the smallest value of the data set from the largest value of the data set.

The values are:

13, 17, 18, 15, 12, 21, 10, 6, 8, 11, 3

Largest Value in this data set: 21

Smallest Value in this data set: 3

Range = Largest Value - Smallest Value

Range = 21 - 3

Range = 18

zepelin [54]

Answer:

The probability is 0.05 or 5%

Step-by-step explanation:

Of 6 cars the probability of 3 being a lemon is:

[tex]frac{{3!3!}{6!}} [\tex]

Picking the first one a lemon is [tex]frac{{3}{6}} [\tex] , the second one also lemon [tex]frac{{2}{5}} [\tex] and the third one [tex]frac{{1}{4}} [\tex].

[tex]frac{{3*2*1}{6*5*4}} [\tex] can be rearanged as

[tex]frac{{3!3!}{6!}} [\tex]

admission to a carnival is $4 for children and $6 for adults. what is the ratio of the number of children to the number of adult

zvonat [6]

The ratio of the number of children to the number of adults in this group is 2 : 3

<h3>How to determine the ratio?</h3>

The admission is given as:

Children=4

Adult = 6

Express as ratio

Ratio = Children : Adult

This gives

Children : Adult = 4 : 6

Simplify

Children : Adult = 2 : 3

Hence, the ratio of the number of children to the number of adults in this group is 2 : 3

1. A tree 5 ft tall grows an average of 8 in. each year. Which equation models the trees height h after x years?

slega [8]

Well we know that it grows 8 in a year. so after 1 year has grown 1 * 8 and after 2 years 2 * 8 and after 3 years 3 * 8 and so on. since x is the year we can say 8x. but it starts with 5 ft so we add in the 5 to get h.
h = 8x + 5

Elsa, Deon, and Carlos served a total of 107 orders Monday at the school cafeteria. Deon served 5 more orders than Elsa. Carlos

ra1l [238]

Answer:

Elsa - 17 orders

Deon - 22 orders

Carlos - 68 orders

Step-by-step explanation:

You need to set variables and create system of equations first.

Elsa= e

Deon= d

Carlos = c

e+d+c=107

d=e+5

c=4e

Now you plug in the values into the equation x+y+z=116

e+(e+5)+(4e)=107

6e+5=107

6e=102

e=17

You plug in the value of x into the other equations.

e = 17

d= 17+5=22

c=4*(17)=68

Rearrange so it corresponds with days...

Elsa - 17 orders

Deon - 22 orders

Carlos - 68 orders
