michelle bought the same fabric on 3 different occasions and recorded the data below what was the price per yard of fabric? answ
bazaltina [42]

Please consider the complete question.

Michelle bought the same fabric on 3 different occasions and recorded the data below.

Yards of Fabric         Total Cost

2.2                             $2.53

3.6                             $4.14

4.2                             $4.83

What was the price per yard of fabric?

To find the cost per yard of fabric, we will divide cost of yards by number of yards.

\text{Cost per yard}=\frac{\text{Cost}}{\text{Number of yards}}

\text{Cost per yard}=\frac{\$2.53}{2.2\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Let us find cost per yard using 2nd set of data.

\text{Cost per yard}=\frac{\$4.14}{3.6\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Similarly we will find cost per yard for 3rd set of data.

\text{Cost per yard}=\frac{\$4.83}{4.2\text{ yards}}

\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}

Therefore, the cost per yard of fabric is $1.15.

Find he measure of Angle A
Yuliya22 [10]

Answer:

25

Step-by-step explanation:

I'm not really sure if this correct its just a guess but here goes.

So as 26x+5 is a vertically opposite angle. So the top angle would be 25x+5.

then we know angles in a triangle add up to 180 degrees so we would add all the angles together. 26x+5+6x-5+20=180. 26x+6x=32x. -5+5=0. 32x+20=180

180-20=160

140/32=5

6×5=30

30-5=25 so angle A is 25?

Please let me know if this is correct and if its not I'm sorry.

Please help me What is the mode of the data shown in this stem-and-leaf plot?
monitta
<h3>Answer:  24</h3>

Explanation:

The mode corresponds directly to the most frequent leaf, ie the leaf that shows up the most. This is because the mode itself is the most frequent value of a list of numbers. Be sure to keep the rows separate. The leaf "5" shows up twice, but it's for two different stems. The leaf "7" is a similar story.

In row two, we have the leaf "4" show up three times which is the most of any leaf for any given stem. Tie that leaf to the stem 2 and we get the value 24.

The mode is 24.

How do you find the average rate change from x = -1 to x = 3
Marrrta [24]

Well to begin, you'll need a graph but you have to do:

y2-y1

---------

x2-x1

(Which is the average rate of change formula.)

In order to find your "y" you look for your x on the graph the move either direction until you touch the graph. Hope this helps.. :)
