Answer:

Explained below.

Step-by-step explanation:

Consider the variables height and weight.

It is usually seen that taller people are heavier than shorter people.

So a regression analysis can be used to specify this belief.

The statistical questions that are being asked here are:

  • What the independent and dependent variables?
  • Are there any other factor influencing the dependent variable other than the independent variable?

The variable <em>Y</em> is considered as the dependent variable and the variable <em>Y</em> is considered as the independent variable.  And the main purpose of the regression analysis is to predict the value of <em>Y</em> when the value of <em>X</em> is given.

The linear regression model can be used to predict the past and future value of the dependent variables provided that the independent variables for those times are provided.

Alejandro loves to go to the movies .He goes both at night and during the he day
Alex17521 [72]

The number of matinee movies attended is 4.

The number of a evening show movies attended is 2.

<u>Step-by-step explanation:</u>

  • Let x represent the number of matinee movies attended.
  • Let y represent  the number of evening show movies attended.
  • Alejandro went to see a total of 6 movies.

Therefore, from the given data the equation can be framed as :

⇒ x + y = 6  ----------(1)

  • The cost of a matinee is $7.
  • The cost of an evening show is $12.
  • Alejandro spent a total of $52.

Therefore, from the given data the equation can be framed as :

⇒ 7x + `12y = 52  ---------(2)

<u>To solve the equations for x and y values :</u>

Mulitply eq (1) and by 7 and subtract eq (2) from eq (1),

  7x + 7y = 42

- <u>(7x + 12y = 52)</u>

  <u>     - 5y = - 10 </u>

⇒ y = 10/5

⇒ y = 2

The number of a evening show movies attended is 2.

Substitute y=2 in eq (1),

⇒ x+2 = 6

⇒ x = 6-2

⇒ x = 4

The number of matinee movies attended is 4.

Since there are 100 squares and 6 aren’t colored in, the answer should be .94. It’s kind of like counting a dollar since 100 pennies = a dollar.
