Answer:
4
Step-by-step explanation:
Assuming the points are on a line in the order F, G, H, I, then segment addition tells you ...
... FG + GH + HI = FI
... 2 + GH + 1 = 7
... GH = 7 - 2 - 1
... GH = 4
Hello there!
The mean score means the average, or the sum of the scores divided by how many scores there were in total.
Let's find the mean first to get it out of the way.
37 + 73 + 77 + 84 + 85 + 115 = 471.
471 / 6 = 78.5
Your mean is 78.5, or 79 when estimated.
The median is the middle number in a sequence listed from least to greatest. It's actually pretty simple to find. I use a pretty easy method to finding it.
First, set the numbers from least to greatest.
37, 73, 77, 84, 85, 115.
Eliminate the first and last numbers.
73, 77, 84, 85.
Repeat the process.
77, 84.
Since there are no middle numbers left, we must average the two numbers.
Add 77 to 84 and divide by 2.
77 + 84 = 161
161 / 2 = 80.5
Your median is 80.5
Our mean is 78.5 or 79, and our median is 80.5 or 81.
The median actually scores better, as it gives us a closer number to the center of what we're dealing with.
I hope this helps!
The answer is 2, because it is asking you, out of the 30 people, who is being counted twice for brown hair and blue eyes. Therefore, you add 17 and 15 to get 32, and because there are only 30 people in the class, you do 32 - 30 = 2 people. Let me know if you're confused or anything :)
Answer:
542 miles
Step-by-step explanation:
St. Paul to Madison, Wisconsin = 260 miles
St Paul to Bismarck, North Dakota = 437 miles
4 round trips to Madison = 4 * 2 * 260 = 2080 miles
3 round trips to Bismarck = 3 * 2 * 437 = 2622 miles
Difference in miles traveled :
2622 miles - 2080 miles = 542 miles
J will be -3,-2
K will be -3,-7
L will be -6,-2
