describe the shape Center and spread of data distribution. are ther any outliers numbers 12 10 11 9 9 10 12 9 8 7 9 10

Answers

Answer 1

Answer: No, there are not any outliers because all of the numbers are relatively close in value

Answer 2

Answer:

Final answer:

The data distribution is a normal distribution with a mean of 10. The spread of the data is 5 and there are no outliers.

Explanation:

The data distribution can be described as a symmetric bell-shaped curve, indicating a normal distribution. The center of the distribution is the mean, which can be calculated by adding up all the numbers and dividing by the total count. In this case, the mean is 10.
The spread of the distribution can be determined by calculating the range, which is the difference between the highest and lowest values. In this case, the range is 12 - 7 = 5.
To determine if there are any outliers, we can use the concept of the interquartile range (IQR). The IQR is the range of the middle 50% of the data. First, we need to calculate the first quartile (Q1), which is the median of the lower half of the data, and the third quartile (Q3), which is the median of the upper half of the data. In this case, Q1 = 9 and Q3 = 11.
The IQR is then calculated as Q3 - Q1 = 11 - 9 = 2. Any data point that falls below Q1 - 1.5 * IQR or above Q3 + 1.5 * IQR is considered an outlier. Since there are no numbers that meet this criteria in this dataset, there are no outliers.

Answers

3/4
Because 6 are not white so 6/8 and divide each by 2
6 divided by 2 = 3
8 divided by 2 = 4
= 3/4

Answer:

1/4 are white. So, 3/4.

How is the difference 14/15-5/12 written as a decimal?

Answers

14 / 15 - 5 / 12 LCM of 12 and 15 is 60.

(14/15)*(60/60) - (5/12)*(60/60)

= 56 / 60 - 25 / 60

= (56 - 25) / 60

= 31 / 60. To change to decimal, use your calculator.

= 0.51667

How do I express the area of a square as a monomial

Answers

Well, the Area of a Rectangle = Length x Width, and a square is a rectangle with all equal sides, which means Length = Width, so the Area of a Square = Length x Length = Length^2, which you can write as x^2. The Area of a Square = x^2, where x is the length of one side of the square.

Can someone please check if I’m right please, I have a test tomorrow.

Answers

You can substitute “x” For your answer and solve the problem that way ^^

It’s a a way to “check” yourself.

If it doesn’t fit in and you not get the answer shown the x substitute is incorrect.

I personally think they are right! I also have a test on two step/one step equations lol
