What is the range of the data in this stem-and-leaf plot? 2 14 19 32.5

QUESTION POSTED AT 26/03/2020 - 02:33 PM

Answered by admin AT 26/03/2020 - 02:33 PM

Answer:

19

Step-by-step explanation:

Stem and Leaf Plots

It is a special table where each data value is split into a stem (the first digit or digits) and a leaf (usually the last digit).

So, in the given plot

the first stem 2 has leafs = 6,7,7

So, the numbers will be 26,27,27

So, in this way we can write the stem leaf plot data in normal data form

Now to calculate range

Range = Highest number - lowest number

The first stem 2 and its first leaf 6 . So,number = 26 is the lowest number

The third stem 4 and its last leaf 5 . So, number = 45 is the highest number

Thus Range = 45-26=19

Hence the range of data  is 19

Answer:

Mode does not exist

Step-by-step explanation:

Mode of any data set is the data with the highest frequency(i.e. that term which is repeated most in the data set)

Here, credit scores in Will's office are:

634 667 644 892 627 821 857 703 654

The lengths of three sides of a triangle are given. Determine whether each triangle is a right triangle. 1. 14 m, 5 m, 4 m 2. 3 in., 4 in., 5 in. Are these right triangles?

In a right triangle, the hypotenuse is always the longest side.  Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides.  For the first "triangle" above: does 14 ^{2} =5 ^{2} +4 ^{2} ?  Let's check.  196 = 25 + 16 so does 196 = 41?  Obviously not.  So that is not a right triangle.  Let's check the second one the same way.  Does 5 ^{2} =3 ^{2} +4 ^{2} ?  25 = 9 + 16.  Does 25 = 25?  Of course it does!  So 1 is not a right triangle, but 2 is!

Jorge needs to ship a thin metal rod to a metalworking shop. The only boxes available for shipping are 7-inch cubes. To the nearest inch, what is the length of the longest metal rod that can be sent? 11 inches 12 inches 13 inches 14 inches

Answer:

The length of the longest metal rod that can be sent is 12 inches.

Step-by-step explanation:

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

D=\sqrt{x^{2}+x^{2}+x^{2} }

= \sqrt{3} x

Here, x is 7 inches.

So, Diagonal is = \sqrt{3} \times7

= 1.732\times7=12.12 inches.

Rounding this to nearest whole number we get 12.

So, the length of the longest metal rod that can be sent is 12 inches.

The data shows the number of grams of fat found in 9 different health bars. 11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19 What is the IQR (interquartile range) for the data? a. 6.25 b.7 c.14.5 d.17.5

Answer:

Option A. 6.25

Step-by-step explanation:

The data shows the number of grams of fat found in different health bars is

11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19

Now we will arrange the data in ascending order

10.5, 11, 11.5, 14.5, 14.5, 17, 17, 18, 19

Middle of the numbers is 14.5 which is median of the data.

We know IQR = Median of first quartile - median of second quartile

Median of first quartile = \frac{1}{2}(11+11.5)=11.25

And median of second quartile = \frac{1}{2}(17+18)=\frac{35}{2}=17.5

Now IQR = 17.5 - 11.25 = 6.25

Therefore Option A 6.25 is the correct option.

Describe each of the following properties of the graph of the cosine function, f(theta) = cos(theta), and relate the property to the unit circle definition of cosine. Amplitude Period Domain Range x-intercepts I know the definitions and descriptions, I just need to know how it relates to the unit circle

Amplitude: the height of the graph from the peak to the axis. On the unit circle it would be the radius (max and min values) at 0, pi/2, 2pi
Period: the length of one full cycle of the cos graph. On the unit circle it is the circumference. The distance around a circle with radius = 1.
Domain: the x value or the values on the horizontal axis. On the unit circle these would be the radian measures around the unit circle such as pi/6, pi/4,
pi/3, pi/2.
Range: the y value or the values on the vertical axis. On the unit circle it would be the cosine value for each radian measure. Such as cos pi/4 = (sqrt2)/2, cos pi/3= 1/2.
X-intercepts: the points where the graph crosses the horizontal axis. On the unit circle these are the cosine values when theta is at the vertical points of the unit circle, pi/2 and 3pi/2.

The data shows the number of grams of fat found in 9 different health bars. 11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19 What is the IQR (interquartile range) for the data?

We need to locate the median of the set given. So, it's important for us to arrange the data in increasing order first. Hence we have

10.5 11 11.5 14.5 14.5 17 17 18 19 
 
Now that we have the value of the median for  the entire set, we now separate the group into a group below and above the median as shown below.

(10.5 11 11.5 14.5) 14.5 (17 17 18 19)

Now, let's find the median for the subgroup. For the lower boundary, the media is (11 + 11.5)/2 = 11.25. As for the upper boundary, we have (17 + 18)/2 = 17.5. 

The interquartile range (IQR) is the difference between the two medians of the lower and upper boundary. Hence, the IQR = 17.5 - 11.25 = 6.25.

Answer: 6.25

The Roth family has liquid assets of $10,000, use assets of $150,000 and investment assets of $34,000. They also have liabilities totaling $108,000. If their total liabilities increase by $7,000 over the next year, by how much would the Roth family need to increase their assets in order to have a net worth of $100,000? a. $7,000 b. $14,000 c. $21,000 d. $28,000

Answer:

c.$21,000

Step-by-step explanation:

In order to solve this you just have to add up assets and liabilities, assets are the money or worth they own, and liabilities are the things htey owe, so assets are:

Liquid: $10,000

Investments: $34,000

Use Assets: $150,000

Total assets: $194,000

Liabilities:108,000+7,000: 115,000

Net worth: $194,000-$115,000= $79,000

So in order to have a net worth of $100,000 they will need to increase their assests in $21,000.
