The data set represents the number of rings each person in a room is wearing. 0, 2, 4, 0, 2, 3, 2, 8, 6 What is the interquartil

forsale [732]

Answer:

$IQR=4$

Step-by-step explanation:

We have been given a data set that represents the number of rings each person in a room is wearing as: 0, 2, 4, 0, 2, 3, 2, 8, 6. We are asked to find the interquartile range of the data.

Let us arrange our data points from least to greatest order.

0, 0, 2, 2, 2, 3, 4, 6, 8.

Let us find median of our data set. Since our data set has 9 data points, therefore, median of our given data set will be value of 5th term, that is 2.

Now let us find lower quartile, which is also known as the median of the data points to the left of median.

We have 4 data points to the left of our median, so our lower quartile will be average of 2nd and 3rd data point.

$Q_1=\frac{0+2}{2}=\frac{2}{2}=1$

Now let us find upper quartile of our given data set, which is the median of the data points to the right of median.

We have 4 data points to the right of the median, so our upper quartile will be the average of 7th and 8th data point.

$Q_3=\frac{4+6}{2}=\frac{10}{2}=5$

Since we know that interquartile range is the difference between upper and lower quartile.

$IQR=Q_3-Q_1$

$IQR=5-1$

$IQR=4$

Therefore, IQR of our given data set is 4.

2. A center-seeking force related to acceleration is _______ force.

steposvetlana [31]

<span>We want to know what force is always pointed towards the center. In order for the motion to be circular, a force must act constantly towards the center of the curvature of the path. It's name comes from Latin: "centrum" is center and "petere", to seek. So we get centripetal force. </span>

Granny Georgette and Kiwi have a combined age of 77. If Kiwi is 13 years less than twice Granny Georgette's age, how old is Kiwi

miskamm [114]

Since they decided to be extremely ridiculous and deleted my answer for "not showing enough work", here I am again:

Since it says that Kiwi is 13 less than TWICE Granny's age, I divided 77 (Granny's age) by 2, which gave me 38.5

I then subtracted 13, since it says that she is thirteen less than that number, which gave me 25.5

I had originally said "20 or 20 and a half years old" because depending on your format of testing/worksheet, you may not have the option of putting halves.
