The cost of a ticket to the circus is $14.00 for children and $32.00 for adults. On a certain day, attendance at the circus was
Evgesh-ka [11]

400 children and 600 adults bought tickets.

Step-by-step explanation:

Given,

Cost of one child ticket = $14

Cost of one adult ticket = $32

Total attendance = 1000

Revenue generated = $24800

Let,

x be the number of children.

y be the number of adults.

According to given statement;

x+y=1000   Eqn 1

14x+32y=24800   Eqn 2

Multiplying Eqn 1 by 14

14(x+y=1000)\\14x+14y=14000\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(14x+32y)-(14x+14y)=24800-14000\\14x+32y-14x-14y=10800\\18y=10800\\

Dividing both sides by 18

\frac{18y}{18}=\frac{10800}{18}\\y=600

Putting y=800 in Eqn 1

x+600=1000\\x=1000-600\\x=400

400 children and 600 adults bought tickets.

There are 5 cocoa pods in a bag.
Virty [35]

Answer:

416 g

Step-by-step explanation:

The mean is calculated as

mean = \frac{sum}{count} , then

\frac{sum}{5} = 398 ( multiply both sides by 5 )

sum of 5 pods = 1990 g

let x be the weight of the sixth pod , then

\frac{1990+x}{6} = 401 ( multiply both sides by 6 )

1990 + x = 2406 ( subtract 1990 from both sides )

x = 416

That is the weight of the sixth pod is 416 g

HELPPP ASAPPPPP!!!!!! PLEASE :(
goldfiish [28.3K]

Step-by-step explanation:

A bar graph serves to visibly represent the frequency of a series of events.

To create a bar graph you can draw on the horizontal axis, each one of the events, and on the axis to verticate the frequency of occurrence.

For this case the possible events are the values from 1 to 5 of the numbered sequence

1 2 3 4 5

The frequency for each number is

4 6 2 6 2.

With these values, a bar graph was made in excel, which is shown in the attached image.

There it is observed that the events with greater frequency are the 4 and the 2.
