Answer:

The center of the data in the dot plot is B. 3.5.

What are mean, median, and mode?

The three main methods for identifying the average value of a set of integers are mean, median, and mode.

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.

The middle value in a list that is arranged from smallest to greatest is called the median.

The value that appears the most frequently on the list is the mode.

The mean of the dot plot is (3 + 2 + 5 + 4 + 1 + 6)/6.

mean = 21/6.

mean = 3.5.

As the number of data is even the median is half of the two middle terms.

median = (5 + 4)/2 = 4.5.

3. Find a solution to the following system of equations.
-3x + 3y = -9
-3x + y = 7

Answers

Answer:

x = 5

y = 2

Step-by-step explanation:

-3x + 3y = -9

3y = 3x - 9

Equation 1. y = x - 3

-3x + y = 7

Equation 2. y = 3x + 7

So, put number 1 equation to number 2's y :

x - 3 = 3x + 7

x -3x = 7 + 3

-2x = 10

2x = 10

x = 10/2

x = 5

And, put x, which is 5 , to the any equation to figure out the y.

This time, I'll use equation number 1.

y = 5 - 3

y = 2

What, if anything, is wrong with the frequency table for this data? 34 21 54 44 33 17 22 56 78 62
48 25 39 64 70 65 52 43 21 22
46 28 39 76 63 39 42 55 29 30



A.
The frequency table should not have been set up in intervals.

B.
The recorded frequency for the interval 40 - 49 is incorrect.

C.
The recorded frequency for the interval 70 - 79 is incorrect.

D.
The frequency table is correct.

Answers

The recorded frequency for the interval 70 - 79 is incorrect, option C is correct.

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We can find the frequency for each interval by counting the number of data points that fall within each range.

There are no values between 10 and 19, so the frequency of 1 for the interval 10-19 is correct.

Similarly, there are no values between 50 and 59 or between 60 and 69, so the frequencies of 4 for the intervals 50-59 and 60-69 are correct.

when we count the values between 40 and 49 the range is 5 which is correct.

when we count the values between 70 and 79, we see that there are 3 value in this range, not 2 as listed in the frequency table.

Hence, the recorded frequency for the interval 70 - 79 is incorrect.
