Which situation best describes a positive correlation? Group of answer choices The height of a candle and the amount of time it stays lit. The price of a pizza and the number of toppings added. The temperature of a cup of hot chocolate and the length of time it sits. The amount of rainfall on Fridays.

Answers

Answer 1

Answer:

The correct option is;

The price of a pizza and the number of toppings added

Step-by-step explanation:

A positive correlation is one in which the variables being correlated, progress in the same direction, such that an increase in one variable will lead o an increase in the other variable;

The price of a pizza  depends on the size of the pizza and the price increases for each additional topping added, such that the price of the pizza will increase as the number of toppings is increased

The variable, the height of the candle and the variable, the length of time it stays on, are positively correlated because, the two variables depends on each other whereby the time it takes to completely burn a candle increases as the length of the candle increases, however, the candle can be put out depending on usage, even if it can stay lit for a longer period of time.

What is scale factor?

Scale factor is the factor which is used to enlarge or smaller the original figure.

Scale factor is the ratio of representation measurement of the figure to the original figures.

On a blueprint, an architect drew a 12-inch line to represent the length of a 30-foot room.  Thus, the scale factor of foot to inch is,

[tex]k=\dfrac{30}{12}[/tex]

Let suppose the line that represents the width of the room is 8 inches long, has the size of room in foot is x. Thus,

[tex]k=\dfrac{8}{x}\\\dfrac{12}{30}=\dfrac{8}{x}\\x=\dfrac{30\times8}{12}\\x=20[/tex]

Thus, the line which represents the width of the room equal to 8 inches long on a blueprint, by the architect, has the size of the room 20 foot.

Step-by-step explanation:

The gas tank in Daniel's car has a capacity of 19.1 gallons.  

On a trip to see his best friend Daniel begins with 12.8 gallons of gas in the tank.  

He stops after driving for 2 hours and fills the tank to capacity with 14.4 gallons.  

When Daniel arrives at his friend's house, he has 3.7 gallons of gas left.  

Total amount of gas filled was (12.8 + 14.4) = 27.2 gallons.

The amount of gas remaining after the trip was 3.7 gallons

The amount of gas, in gallons, used by Daniel on his trip was 27.2 - 3.7 = 23.5 gallons

Answer:   The equation  60 + x= 3x -70   could be set up to solve for x.  

Step-by-step explanation:

The two remote  interior angles sums will equal to the exterior angle .

Meaning that angle 60 plus angle x has to equal to angle 3x -70.

60 + x= 3x -70       Now solve for x by adding 70 to both sides

+70             +70

  130 = 2x        Divide both sides by
