Answer:
For 25, the answer is C
Step-by-step explanation:
How I got the answer for 25 is:
To find the mean absolute deviation of the data, start by finding the mean of the data set.
How you do this is first you need to find the sum of the data values, (add all the numbers together) and divide the sum by the number of data values.(and divide that number by how many numbers you added together in the first place)
In this case, we'd be adding 44 + 39 + 47 + 38 + 38 + 41 + 40, and that equals 287. Now we'll divide 287 by how many numbers we added together, which is 7 numbers. 287 ÷ 7 = 41. That's the mean of the data set.
Next, we'll find the absolute deviation of the mean. How we do this is, we find how far away all the numbers are from 41.
44 is 3 away from 41
39 is 2 away from 41
47 is 6 away from 41
38 is 3 away from 41
41 is 0 away from 41
40 is 1 away from 41
So now, we add all of the distances together (3, 2, 6, 3, 0, and 1), and that equals 15! Now we do 15 ÷ 6, which is 2.5 and the reason we're dividing by 6 is because we're dividing by the number of distances we added together. Now, if you look on your worksheet, the closest answer to 2.5 is C, (2.6) so I'd chose that as the correct answer. I hope that helped!
Since side BC must equal FE, x - 13 = 20. Therefore x = 33
Answer:
394.67 minutes (or about 6.58 hours)
Step-by-step explanation:
<u>For 145.8 feet long fence:</u>
At a rate of 2.25 feet per minute, its gonna take him
minutes to pain
Also
At a rate of 0.75 feet per minute, its gonna take him
minutes to stain
<u>For 76.2 feet long fence:</u>
At a rate of 2.25 feet per minute, its going to take him
minutes to pain
At a rate of 0.75 feet per minute, its gonna take him
minutes to stain
In total, it's gonna take him:
64.8 + 194.4 + 33.87 + 101.6 = 394.67 minutes
In hours, that is 394.67/60 = 6.58 hours
Answer:53-6
Step-by-step explanation:
That’s the answer
If the ratio of girls to boys in Mr. Hansen's class is 4:5, and the ratio of girls to boys in Ms. Luna's class is 8:10, then the equation that correctly compares the ratio of both Mr. Hansen's class and Ms. Luna's class are 4/5 = 8/10.
