Hi!
Let's start with the mean.
The mean is all the numbers added together, divided by how many numbers there are.
13+16+16+10+6+12+4+12+16=105
there are 9 numbers so..
105/9 = 11.7
The mean is 11.7
Find the median.
The median is the number in the middle of the data set when the numbers are in numerical order.
4, 6, 10, 12, 12, 13, 16, 16, 16
The median is 12.
Find the mode.
The mode is the number that is repeated the most.
4, 6, 10, 12, 12, 13, 16, 16, 16
The mode is 16
Find the range.
The range is the difference of the smallest number from the biggest number.
16 - 4 = 12
The range is 12
The answer is 11.7, 12, 16, 12
Hope this helps! :)
I think it is -5,-4,-1/4, 1.75, 6.2, 9, 18 1/2, 21
These are the steps:
1. Find the area of the trapezium {Whole figure).
2. FInd the area of the rectangle (unshaded).
3. Area of the shaded = Area of trapezium - Area of the rectangle.
<u>Step 1: Find the area of the trapezium</u>:
Formula : Area of trapezium = 1/2 (a + b)h
Area = 1/2 ( 25 + 15) (12) = 240 yd²
<u>Step </u><u>2 :</u><u> Find the area of the rectangle</u>:
Formula : Area = Length x Width
Area = 12 x 3 = 36 yd²
<u>Step 3: Find the shaded region:</u>
240 - 36 = 204 yd²
Answer: 204 yd²
The initial function is slope
=> slope = 7-1/6-0 = 6/6 = 1
Hope this helps you :)
