A popular board game manufacturer was interested in the relationship between the amount of time it takes to play a game and how well that game is rated among board game players. Information was collected on several board games, and was used to obtain the regression equation y = 27.273x + 18.182, where x represents time it takes to play (in hours) and y is the predicted rating of that game (in points). What is the predicted rating of a game that takes 90 minutes to play?

18.182 points
59.0915 points
90 points
2,472.752 points

Answers

Answer 1

Answer:

B- 59.015

Step-by-step explanation:

Answer 2

Answer:

The answer is B. I don't know why everyone downvoted the first answer. So here's some fancy work so you know its right.

90 minutes/1 hour = 1.5 hours [one hour = 60 minutes]

(you can only put hours in for x)

27.273(1.5) + 18.182 = 59.0915 (B)

==================

if you're looking for the question "What is the predicted rating of a game that takes 1 hour to play?" the answer is (C), 45.455 points".

Some people advise that in very cold weather , you should keep the gas tank in your car more than half full. Irene's car had 5.80 gallons in the 13- gallon tank on the coldest day of the year. Irene filled the tank with gas that cost 3.80 per gallon. How much did Irene spend on gas?

Answers

Answer:

22.04

Step-by-step explanation:

We are told in the question that:

Irene filled the tank with gas that cost 3.80 per gallon.

She has 5.80 gallons in her tank.

Hence:

1 gallon of gas = 3.80

5.80 gallons =

Cross Multiply

5.80gallons × 3.80/1 gallon

= 22.04

Therefore, Irene spent 22.04 on gas

33rd term 189.6, 172.3, 155​

Answers

Answer:

[tex]a_{33}[/tex] = - 364

Step-by-step explanation:

There is a common difference between consecutive terms. that is

d = 172.3 - 189.6 = 155 - 172.3 = - 17.3

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 189.6 and d = - 17.3 , thus

[tex]a_{33}[/tex] = 189.6 + (32 × - 17.3) = 189.6 - 553.6 = - 364

The sum of two numbers is no more than 28. Let x represent the first number, and let y represent the second number. Which inequality represents this situation?

A) y
B) y<_x+28

C) x+y <28

D) x+y<_28

Answers

Answer:

x+y < 28

Step-by-step explanation:

1. Look at your variables: x is the first number and y is the second.

2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.

3. Write out your inequality: x+y < 28

FIRST, we want to understand every property:

Associative Property: The associative property states that you can add or multiply regardless of how the numbers are grouped so (5 + 4) + 3 = 5 + (4 + 3)

Commutative Property: Commutative is the one that refers to moving stuff around so 3 + 2 = 2 + 3

Additive Inverse Property: This is the number that when added to the original number, equals 0 or it's the opposite of the number so 5 <- is the original number and -5 <- is the additive inverse.

Simplify: Is just to add like terms, and make the equation the simplest.

Let

x = number of tickets

y = cost

For each row, divide the cost over the number of tickets

Row one:  y/x = 3/2 = 1.5

Row two: y/x = 6/4 = 1.5

Row three: y/x = 9/6 = 1.5

Row four: y/x = 12/8 = 1.5

Row five: y/x = 15/10 = 1.5

The constant of proportionality is 1.5

Alan purchased 16 shares of company stock for $390.40. A month later, the total value of his shares fell to $291.20. What is the current price per share if each share costs the same?
A.
$6.20
B.
$18.20
C.
$24.04
D.
$24.40

Answers

Answer: $18.20

Step-by-step explanation:

390.40/16 to find the initial costs of the shares. That would be $24.40 per share. However, since the stock has fallen, you would do that same division, but with the new value. 291.20/16, which is $18.20

Answer:

$18.20 per share is the value of each stock currently

Step-by-step explanation:

Take the value the stocks are worth now and divide by the number of shares

291.20/16

$18.20 per share

$18.20 per share is the value of each stock currently
