A linear equation of the trend line that models the data points contained in the table is y = 0.09x + 16.27.

<h3>How to find a trend line for the data?</h3>

In order to determine a linear equation of the trend line (line of best fit) that models the data points contained in the table, we would have to use a scatter plot.

In this scenario, the body weight (in lbs) of the high school students would be plotted on the x-axis of the scatter plot while the backpack weight (in lbs) would be plotted on the y-axis of the scatter plot.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line (line of best fit) on the scatter plot.

From the scatter plot (see attachment) which models the relationship between data points in the table, a linear equation of the trend line is given by:

y = 0.09x + 16.27

A 56-foot piece of siding is cut into three pieces so that the second piece is twice as long as the first piece and the third pi

ELEN [110]

The lengths of the first, second and third piece are respectively 8 ft, 16 ft and 32 ft

<h3>How to solve Algebra word Problems?</h3>

Let the length of the first piece be x.

Let the length of the second piece be 2x

Let the length of the thrid piece be 4x

Since the total length of the piece is 56 ft, then we can say that;

x + 2x + 4x = 56

7x = 56

x = 56/7

x = 8 ft

Thus, length of first piece = 8 ft

Length of second piece = 2 * 8 = 16 ft

Length of third piece = 4 * 8 = 32 ft

Thus, the lengths of the first, second and third piece are respectively 8 ft, 16 ft and 32 ft

Find the slope of the line passing through the points (8,-3) and (4,-1)

docker41 [41]

$\rm \to m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$\\ \\$

$\rm \to m = \dfrac{ - 1 - 3}{4 - 8}$

$\\ \\$

$\rm \to m = \dfrac{ - 4}{4 - 8}$

$\\ \\$

$\rm \to m = \dfrac{ - 4}{ - 4}$

$\\ \\$

$\rm \to m = \cancel \dfrac{ - 4}{ - 4}$

$\\ \\$

$\rm \to m = 1$

Two trains 150 miles apart are traveling toward each other along the same track. The first train goes 60 miles per hour; the sec

Nataly_w [17]

Answer:

120 miles

Step-by-step explanation:

Distance = 150 miles

train 1 = 60 mph

train 2 = 90 mph

directions of trains = towards each other

Time to meet = 150/(60+90) = 150 miles / 150 mph = 1 hour

Speed of fly = 120 mph

Since fly has been flying for one hour, it travelled 120 miles.
