Answer:
√841
Step-by-step explanation:
You would use pythagorean theorem to solve this problem:
a² + b² = c²
a = 20 b = 21
20² + 21² = 400 + 441 = 841
√841

Answer:
Step-by-step explanation:
First step
Put the numbers in numerical order.
64 99 100 102 110 110 111 112
Median
Median is the middle number. If the number of numbers is even then you take the middle 2 and average them.
This has 8 entries so you take the middle 2 and average them.
102 and 110 are the middle 2. They can be averaged.
(102 + 110)/2 = 212/2
212 / 2 = 106
The median is 106.
Mode
The mode is the entry with the most number that are the same.
110 is given twice. Nothing else is. So the mode is 110
Mean
The mean is the average. You add the eight numbers and divide by 8.
Sum = 64 + 99 + 100 + 102 + 110 + 110 + 111 + 112
Sum = 808
Now divide by 8
Mean = 808/8
Mean = 101
Answer:
y= 5x - 3
Step-by-step explanation:
For the slope, use this formula (y2 - y1) / (x2 - x1)
I used (1,2) and (2,7) from the chart
plug 7 for y2, and 2 for x2
then plug 2 for y1, and 1 for x1
7-2 / 2-1 = 5/1 = 5 <-- this is the slope.
Find the y intercept by plugging in (1,2) into y=5x + b
2 = 5(1) +b
2= 5 + b (subtract 5 on both sides)
-3 = b
So the answer is y= 5x - 3
