B) Break 48 into 12 groups of 4.
C) Break 12 into 4 groups of 48.
D) None of these.
Answer: B) Break 48 into 12 groups of 4.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given.
48÷12
This expression means dividing the number 48 by 12, or in other words, break 48 into 12 groups of 4.
So, if we solve :
48÷12= 4
In conclusion, the correct option is B)Break 48 into 12 groups of 4.

Answer: 92cm2
Step-by-step explanation:
top shape
A = lw
= 7 * 4
= 28cm2
bottom shape
A = lw
= 4 * 10
= 40cm2
triangle
A = bh/2
= 8*3
= 24cm2
28+40+24 = 92cm2
No, any one of the 10 mayflies in the group live for 1 full day.
The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations and their mean.
The life spans of 10 adult mayflies have a mean of 4 hours and a MAD of 2 hours.
Fill in the table below with possible values for the life spans. You can use the same values more than once.
Mean = 4 hours.
Mean absolute deviation = 2 hours.
Assume that the life spans of each fish is 4 hours;
Then mean = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4/10
= 40/10
= 4 hours.
No fish can live for a full day.
Hence, No, any one of the 10 mayflies in the group live for 1 full day.

Step-by-step answer:
Assuming MAD stands for mean absolute deviation (2 hours), then the total absolute deviation from the mean (4 hours) is 10*2=20 hours.
If one of the flies live for 1 full day, the absolute deviation is 24-4=20 hours. This automatically requires the other flies live exactly 4 hours to have the MAD equal to 20 hours.
However, the above arrangement does not give a mean of 4 hours, but a mean of (24+9*4)/10=6 hours. This means that it is not possible to have a fly living for a full day.
USE EQUAL INTERVALS to make a frequency table for the average number of movies per person.
Alright! Let me draw one out for you! c: Here you go! I hope this helps! It took me a while ~w~
Don't juge my handwriting It took a while T~T I couldn't put in the whole picture but the pattern was.
Turkey - Japan : 1.7
UK - Finland: 2.8
Austria - Germany : 3.3
Spain - Sweden : 4.4
Denmark- Switzerland : 5
France - Norway : 5.5
Canada - U.S : 7.5
Hope this helps!~
Answer:
Classes Frecuency
0.0 - 0.9 1
1.0 - 1.9 5
2.0 - 2.9 5
3.0 - 3.9 2
4.0 - 4.9 1
Step-by-step explanation:
The scale of equal intervals is characterized by a common and constant unit of measure that assigns a number equal to the number of units equivalent to that of the magnitude of the observed element. It is important to note that the zero point in the scales of equal intervals is arbitrary, and does not reflect at any moment absence of the magnitude that we are measuring.
This scale, besides having the characteristics of the ordinal scale, we find that the assignment of the numbers to the elements is so precise that we can determine the magnitude of the intervals (distance) between all the elements of the scale. Undoubtedly, we can say that the scale of intervals is the first truly quantitative scale and the characters that have this scale can be calculated all the statistical measures except the coefficient of variation.
The data is classified into classes divided into equivalent intervals. The range is then divided by the number of classes, which gives the common difference.
1. Define the number of equals intervals .
Each interval increase 0.9.
2. Make a frecuency table.
We select each country which is within the range of each class and we add in the frecuency column the countries that fall within the range of that class.
Classes Frecuency
0.0 - 0.9 1
1.0 - 1.9 5
2.0 - 2.9 5
3.0 - 3.9 2
4.0 - 4.9 1
