ZanzabumX [31]

Answer:

Choice B

Step-by-step explanation:

We can perform a least squares regression model in Ms. Excel to determine the equation of the line of best fit for the data given;

The first step is to enter the data into any two adjacent columns of an excel workbook. Next, click on the Data ribbon followed by the Data Analysis tool pack. We then proceed to select regression from the pop-up window. The final step is to select the y range and the x range of values from our data.

Once we click ok, Excel returns our least squares regression model as shown in the attachment below.

The coefficient of X variable 1 is our slope.

A summer camp cookout is planned for the campers and their families. There is room for 525 people. Each adult costs $9, and each
vodomira [7]

Answer:

<em>The System of Inequalities in this real-world scenario is:</em>

x+y < = 525

9x+5y < = 1200

Step-by-step explanation:

In this question we are asked to to write a system of inequalities, thus a system of relating two variables, where the relationship will be of the form either greater > or less < or equal.  

<u>Given Information:</u>

→ Maximum number possible in the summer camp: 525

→ People attending are Adults (lets call them x and Campers (lets call them y)

→ Ticket Cost for Adults is $9

→ Ticket Cost for Campers is $5

→ Maximum budget available for both Adults and Campers is $1200

From these information we can obtain 2 Inequalities to define our system of equation.

The first inequality will be with respect to the Maximum Number of People possible which reads as:

x+y\leq 525         [sum of adults and campers should be less or equal to maximum number of people possible]

The second will be with respect to the Maximum Budget available which reads as:

9x+5y\leq 1200         [sum of the cost per ticket for adults and campers should be less or equal to maximum budget available]

<em>Thus the System of Inequalities in this real-world scenario is:</em>

x+y\leq 525\\9x+5y\leq 1200

<em>Which if solved can give us the values for x and y, thus the number of adults and numbe of campers attedning the summer camp. </em>

Eddi Din [679]

Answer:

Each Caramel Macchiato is $5.60

Step-by-step explanation:

You could write the equation 5x+7=35

x stands for the price of each macchiato

the +7 is the $7 left-over after getting 5 macchiatos.

Then solve the equation.

1) subtract 7 on both sides

5x=28

2) divide by 5 on both sides

x=5.60
