1st page:

1. The scatter plot does not show a linear model.

2. Since the plotted data are all around the temperature of 10, the slope would be a horizontal line at 10. A horizontal line does not have any slope, this tell me that the average temperature stays an average of 10 no matter what the humidity level is.

3. There is no vertical intercept shown.

2nd page:

1. yes, because there were 2 small clusters separated by a little bit of space.

2. I think the location of the area the data came from may change the relationship between the variables.

3. I think by switching the axis's the data may be grouped closer together since most of the data points are along a vertical line.

2. Solve x - 19 <81. Then graph the solution.

mr_godi [17]

Answer:

x<100

Step-by-step explanation:

The given equation is :

x-19<81

Adding 19 to both sides of the equation.

x-19+19<81+19

x<100

It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.

Javon needs two 5 foot pieces of rope for the sides of the ladder. She needs 7 pieces of rope each 18 inches long for the steps.

garik1379 [7]

Answer:

20 1/2 feet

Step-by-step explanation:

18 inches is 1 1/2 feet. We can add up the lengths. Remember that multiplication is used to simplify repeated addition.

rope needed = 2×(5 ft) +7×(1 1/2) ft

= 10 ft + 10 1/2 ft

= 20 1/2 ft

<em>Comment on the solution</em>

There are many ways you can go at the solution of this. The one you choose may depend on the kind of aritmetic you're comfortable with.

Since one of the dimensions is given in inches, and the result is required in feet, at some point you need to convert from inches to feet. It is useful to know that 12 inches equal 1 foot. That tells you that you can divide the number of inches by 12 to get the number of feet. (18 inches = 18/12 feet = 3/2 feet = 1 1/2 feet)

You can add the step lengths in inches (18 inches × 7 = 126 inches = 10 1/2 feet) or in feet (1 1/2 feet × 7 = 10 1/2 feet).

___

Since one of the dimensions involves a fraction of a foot, at some point you have to deal with arithmetic involving fractions. Here, we have assumed you know how to do that (this is college math, after all).

Modern calculators are quite versatile in the sorts of expressions they can evaluate. For mine, it would be convenient to write it as ...

2×5+7×(18/12) . . . . would give 20 1/2
