Answer:

The correct option is 2) Yes because it passes through the center of data points.

Step-by-step explanation:

Consider the provided graph shown in the figure.

A scatter plot is a possible line which may or may not actually pass through the points but it best fit on the provided data set.

It requires 2 sets of data where the first one(x) is independent and the second data is dependent(y)

It is mathematical diagram that plots pairs of data on x and y axis in order to identity the relationship between the data sets.

Now consider the provided scatter plot.

The line passes through the center of the data points and best fit in order to visualize the strength of correlation.

Hence, the correct option is 2) Yes because it passes through the center of data points.

A video game system and several games are sold for $652. The cost of the games is 3 times as much as the cost of the system. Fin
vesna_86 [32]

Answer:

The cost of the system is $163 and The cost of the games is $489

Step-by-step explanation:

∵ A video game system and several games are sold for $652

∵ The cost of the games is 3 times as much as the cost of the system

→ Assume that the cost of the system is $x

∵ The cost of the system = x

∴ The cost of the games = 3 × x = 3x

∵ The total cost of the system and the games = 652

→ Equate the sum of the cost of the system and the cost of the games

   by 652

∴ x + 3x = 652

→ Add the like terms in the left side

∴ 4x = 652

→ Divide both sides by 4 to find x

∵ \frac{4x}{4}=\frac{652}{4}

∴ x = 163

∵ The cost of the system = x

∴ The cost of the system is $163

∵ The cost of the games = 3x

∴ The cost of the games = 3(163) = 489

∴ The cost of the games is $489

How do you triple rhe surface area of a cone
Gelneren [198K]
Increase the height so that the slant height triples.

For example:
  Say that lateral height is 2 and the radius is 1. The lateral surface area would be 6.28

 if I make the lateral height 6, which is triple the original lateral height, the lateral surface area becomes 18.84, which is triple the original surface area

Hope I help :P
