Find the initial value of the car and the value after 11 years.
Round your answers to the nearest dollar as necessary.

Answers

Answer:

v(0) = 19,900, v(11) = 3,787.36

Step-by-step explanation:

the Gonzales family has three children on summer break they went to an amusement park they bought 3 children tickets for 18.50 and 2 adults tickets if they spent a total of 104.50 how much was the price of the parents

(a) write an equation to represent this situation use x to represent the price of each adult tickets



(b) how much was the price each adult tickets ​

Answers

Answer:

a. 18.50 + x = 104.50

b. x = 86

Step-by-step explanation:

To get the price of the adult tickets use inverse operation and subtract 18.50 on both sides. When you subtract 18.50 from 104.50 you should get 86. so x = 86.

A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.

Which events are independent? Choose all that apply.

Answers

Answer:

A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.

Step-by-step explanation:

An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.

This is an independent event since its outcome is the same irrespective of the events.

What are independent and dependent variables?

Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on the other.

If a variable is taking its values independently of any visible direct cause, then that variable is called an independent variable.

The variables that take their values based on some other variables' values are called dependent variables.

A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.

This is an independent event since its outcome is the same irrespective of the events.
