Answer:

Step-by-step explanation:

Common examples of "unit rate" follow:

miles per hour (mph). How many miles are covered in 1 hour of driving?

25 cents/pen: each pen costs 25 cents each.

Suppose I know I can pack 1/4 box in 20 minutes. How many boxes can I pack in 1 hour? That would be a unit rate. To find it, write out the ratio

1/4 box 60 min

------------- and multiply this by the conversion factor ---------------

20 min 1 hour

... which results in 3/4 box per hour (a unit rate)

notsponge [240]

Answer:

y = 3x - 1

Step-by-step explanation:

Let's start with the two points.

y = mx + b

-19 = -6m + b

5 = 2m + b

Subtract the first from the second.

24 = 8m

m = 3

5 = 2*3 + b

b = -1

Explain why it's possible to draw more than two different rectangles with an area of 36 square units but if not possible draw mo

gavmur [86]

The area of a rectangle is the result of multiplying its length times its width. So the rectangles length and width are factor pairs of the area.

The number 36 has four non-equal, whole number factor pairs: (1,36) ; (2,18) ; (3,13) ; (4,9)

*note : (6,6) makes a square not rectangle

The number 15 has only two whole number factor pairs (1,15) and (3,5)

Pls answer this with a picture showing the correct box plot

faust18 [17]

Answer/Step-by-step explanation:

To find out the mistake of the student, let's find the min, max, median, Q1 and Q3, which make up the 5 important values that are represented in a box plot.

Given, {2, 3, 5, 6, 10, 14, 15},

Minimum value = 2

Median = middle data point = 6

Q1 = 3 (the middle value of the lower part of the data set before the median)

Q3 = 14 (middle value of the upper part of the data set after the median)

Maximum value = 15

If we examine the diagram the student created, you will observe that he plotted the median wrongly. The median, which is represented by the vertical line that divides the box, ought to be at 6 NOT 10.

See the attachment below for the correct box plot.
