Answer:
c = 53 yd is the answer.
Step-by-step explanation:
a = 45 yd
b = 28 yd
c = ?
According to the Pythagorean Theorem,
a² + b² = c²
45² + 28² = c²
2025 + 784 = c²
c² = 2809
c = 53 yd
∴ The dog runs 53 yd
Hi there!
18 is 20% of 90. Why, you may ask?
To solve we just divide both sides by 0.2
We would start off with 0.2x = 18.
NOW divide.
x = 90.
We can check this by seeing that 20% of 90 is equal to 18.
Hope this helps!
Hopefully this helps you.

Answer:
Median
Step-by-step explanation:
The median will be a more accurate description of the dataset. The mean (average) will be more sensitive to outliers that will pull it higher or lower. In contrast, the median is less sensitive to these higher or lower values.
Imagine the following data:
1, 2, 2, 2, 2, 2, 3
The median here is 2 (the middle value) and the mean (average) is 2.
Now imagine this case:
1, 2, 2, 2, 2, 3, 100
Very similar, but one of the 2s is now a 100. Most of the values are really low, but there is one high value (100).
The mean in this case is now much higher! It's 16.
But the median (middle value) is still 2.
As this shows, the mean can be moved around by outliers but the median is less sensitive.
