Answer:

165.

Step-by-step explanation:

The nth term is an = a1 + (n - 1)d.

The common difference (d) is 7 and the first term (a1) is -3, so the 25th term

= a25 = -3 + (25-1)*7

= =3 + 24*7

= 165.

A lottery consists of one $2000 winner, three $500 winners, and ten $100 winners. a total of 1000 tickets are sold for $10 each.

Semenov [28]

Answer: -5.5

WOKINGS

Given that the lottery has the following number of winners:

One $2000 winner

Three $500 winners

Ten $100 winners

Also Given,

A total of 1000 tickets are sold

Each ticket costs $10

The expected winning for a person purchasing one ticket is the sum of the products of the gain/loss and their corresponding probability.

There is one $2000 winner

There are 1000 tickets

The probability of winning $2000

= 1/1000

= .001

There are three $500 winners

There are 1000 tickets

The probability of winning $500

= 3/1000

= .003

There are ten $100 winners

There are 1000 tickets

The probability of winning $100

= 10/1000

= .01

Since each ticket costs $10

Everyone who buys a ticket automatically loses $10.

Therefore, the probability of losing $10 is 1

Now to calculate the expected winning for a person purchasing one ticket

= 2000(.001) + 500(.003) + 100(.01) – 10(1)

= 2 + 1.5 + 1 – 10

= -5.5

The expected winning is -5.5. This implies that a person playing this lottery can expect to lose $5.50 for every one ticket that they purchase.

The volume (in cubic feet) of a room is represented by 12z3−27z12z3−27z. find expressions that could represent the remaining dim

ratelena [41]

The volume of a room = length * width * height
 =12z³-27z
And by the analysis:
 The volume = 12z³-27z
 = ( 3z ) ( 4z²-9 ) ⇒ by taking (3z) common
 = ( 3z )( 2z+3 )( 2z-3 ) ⇒ the difference between two squares

So the dimensions of the room will be 3z , 2z+3 , 2z-3
