A stem and leaf plot shows the number of kilometers walked for charity. The plot is titled 'Kilometers Walked for Charity.' The numbers 12, 13, 14, 15, 16, and 17 are in a vertical column to the left of a vertical line. · On the same line as 12 but on the right of the vertical line are the numbers 3, 3, 6, 7, 9, and 9. · On the same line as 13 but on the right of the vertical line are the numbers 1, 1, 4, 5, and 5. · On the same line as 14 but on the right of the vertical line are the numbers 0, 0, 2, 3, 3, 8, 8, and 9. · On the same line as 15 but on the right of the vertical line are the numbers 2, 2, 2, 2, 2, 3, 5, 5, and 7. · On the same line as 16 but on the right of the vertical line are the numbers 4, 5, 5, 9, and 9. · On the same line as 17 but on the right of the vertical line are the numbers 3 and 5. The key to the stem and leaf plot identifies that 12 vertical line 3 means 12.3. a. Describe how to find the range of the data set. b. Find the range.

Answers

Answer 1

Answer:

For part A: Range is difference between the highest value and lowest value of the data set.

For part B: Range is 5.2

Step-by-step explanation:

For part A:

Range of a data set is difference between the highest value and lowest value of the data set.

For part B:

From stem and leaf and it's key ,we can write our data set as

12.3,12.3,12.612.7,12.9,12.9,13.1,13.1,13.4,13.5,13.5,14.0,14.0,14.2,14.3,14.3,14.8,14.8,14.9,15.2,15.2,15.2,15.2,15.2,15.3,15.5,15.5,15.7,16.4,16.5,16.5,16.9, 16.9, 17.3,17.5.

Lowest value of data set = 12.3

Highest value of the data set =17.5

So, range = highest value- lowest value= 17.5-12.3 =5.2

Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of hotdogs. How much did each package of hotdogs cost?

Answers

Answer:

hotdogs 3.45

rolls 2.60

Step-by-step explanation:

6h + 8r = 41.5

r=h-.85

6h + 8(h-.85)=41.5

6h + 8h - 6.8 = 41.5

14h = 41.5 + 6.8

14h = 48.3

h=48.3/14

h=3.45

r=3.45-.85=2.6

Answer:

(x + 1 ) is a factor

Step-by-step explanation:

Given a polynomial with roots x = a, x = b , then the corresponding factors are

(x - a) and (x - b)

From the graph

The roots are x = - 1 and x = 4 , thus factors are

(x - (- 1)) and (x - 4) , that is

(x + 1) and (x - 4)

(x + 1) is the required factor

What is the measure of the indicated angle 103° ?

Answers

Answer:

77 degrees.

Step-by-step explanation:

180-103=77

77 degrees is the measure of that temperature 180-103=77

The measure of an angle is 66° . What is the measure of its complementary angle ?

Answers

Answer:

24º

Step-by-step explanation:

90-66 = 24º. So since complementary angles are 2 angles that add up to 90 degrees. That means that 66 + x = 90 using the information given. Then we use algebra and get that x =24. Therefore the answer is 24º.

Answer:

The supplement of 66° is the angle that when added to 66° forms a straight angle (180° ).

Step-by-step explanation:

A supplementary angle is an angle that equals 180°. So now we know that the two angles added together will give us 180°, we can use this to check at the end.

Let's call the smaller angle x

We also know that the larger number is 66° more than the smaller. This gives us:

x+x+66°=180°.

x is equal to the smaller angle, and the second angle is (x) - the smaller number with an extra 66°, giving us the difference.

Now we can simplify this by subtracting 66° from both sides.

So you need to take two points off the graph. (x,y) and (x,y)

After that use those points to plug it into this equation

your gonna want to take the Y points from both and subtract from each other.

Do the same for the X points.

Y2-Y1

X2-X1

You'll then divide The Y by the X and that the Rise over Run. When you graph that. That'll be your answer.
