Answer:
The mean increases by 3.
Step-by-step explanation:
<u>What's an outlier?</u>
- An outlier is a data point that's very different from the other data points. In this example, the outlier is 50, as the other data points are around the number 80.
<u>What's the mean of a data set?</u>
- The mean is the average of a data set. It's found by adding up all the numbers in the set and then dividing by the number of data points there is.
<u>How do we solve this problem?</u>
First, we find the mean of the data set with the outlier, 50.
Next, we find the mean of the set without the outlier.
Lastly, we subtract 77 from 80 to find the difference.
Therefore, the answer is The mean increases by 3.
Answer:
-2 and 3 along the horizontal line
Step-by-step explanation:
There are two axes, plural for axis; the two main lines. The one that runs vertically is the y axis and the one that runs horizontally is the x axis. Now when you see the parabola which is the curve, it meets at three points. The points are -2 , 6, and 3. the ones we are focusing on are the -2 and 3 since they are the numbers/points on the x axis
Hello again!
The area of a triangle is A=1/2*b*h where b is base and h is height.
Since we have the area and base, we can set up an equation to find h and get the height:
18=1/2*3*h
6=1/2*h
12=h
So the height of the triangle is 12 feet.
Answer:
58°
Step-by-step explanation:
65°+57°=122°
180°-122°=58°
