5^2-100=X
(5*5)
25-100=X
-75=X
hope this helps
Throughout this, I'm assuming that the scale is: 1 square = 1
Not 100% sure if my answers are correct.
Question 1:
The x coordinate must be 2 and the y coordinate must be -1.
Question 2:
The x coordinate would be -2 and the y coordinate would be -1.
If the outliers are not included, what is the mean of the data? 76,79,80,82,50,78,83,79,81,82.

50 is the only outlier so take 50 out of the set then add the other 9 data points and divide by 9.<span>
76 + 79 + 80 + 82 + 78 + 83 + 79 + 81 + 82 = 720 / 9 = 80</span>
Answer:
B. 5
Step-by-step explanation:
The range of a data set in statistics is the difference between the largest and the smallest values. While range does have different meanings within different areas of statistics and mathematics, this is its most basic definition, and is what is used by the provided calculator.
example, 2,10,21,23,23,38,38
38 - 2 = 36
Answer:
The longer diagonal has a length of 7.3 meters.
The angles are 31.65° and 18.35°
Step-by-step explanation:
If one angle of the parallelogram is 50°, another angle is also 50° and the other two angles are the supplement of this angle. so the other three angles are:
50°, 130° and 130°.
The longer diagonal will be the one opposite to the bigger angle (130°), and this diagonal divides the parallelogram in two triangles.
Using the law of cosines in one of these two triangles, we have:




So the longer diagonal has a length of 7.3 meters.
To find the angles that this diagonal forms with the sides, we can use the law of sines:





The other angle is B = 50 - 31.65 = 18.35°
