We can put it like this
162/18=486/x
cross multiply
162*x = 486 * 18
162*x = 8748
divide both sides by 162
x = 54

It will take her 54 minutes to travel 486 miles

Hope this helps :)

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function? Loc
adoni [48]

Answer:

Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

In this problem we have

m=2\\b=-6

so

y=2x-6

To graph a line we nee minimum two points

we have the y-intercept (0,-6)

Using the slope find out the second point

Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

so

From the point (0,-6), count right 1 units and up 2 units

(0+1,-6+2)

(1,-4)

so

Plot the points (0,-6) and (1,-4) and join them to graph the line

therefore

Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

The median of this box and whisker plot is 73

A box and whisker plot is defined as a graphical method of displaying variation in a set of data. In most cases, a histogram analysis provides a sufficient display, but a box and whisker plot can provide additional detail while allowing multiple sets of data to be displayed in the same graph. Box and whisker plots are very effective and easy to read, as they can summarize data from multiple sources and display the results in a single graph. Box and whisker plots allow for comparison of data from different categories for easier, more effective decision-making.

From the given data, following can be inferred

  • Population size: 18
  • Median: 73
  • Minimum: 55
  • Maximum: 89
  • First quartile: 61.75
  • Third quartile: 83.5
  • Interquartile Range: 21.75

which is demonstrated in the box and whisker plot below

In figure, what is the value of y?
Gelneren [198K]

First, find the value of x.  Note that the angles x, 0.5x and 3x sum up to 4.5x, and that this sum has the value 180 degrees.  Solving this equation for x, we get x = 40 degrees.

Now, 0.5x and 0.5y are vertical angles, and thus x = y.  So, with x being 40 degrees, y = 40 degrees.
