Answer:
yes
Step-by-step explanation:
A^2 +B^2 =C^2
10^2 + 10.5^2 = 14.5^
100 + 110.25 = 210.25
210.25 = 210.25
The sum of the first n natural number = n * (n+1) / 2, for n a natural number.
For example, you want to calculate the sum and average of any five numbers entered by the user. i.e., If you want to calculate the sum and average or percentage of multiple user-entered numbers, then please refer to the following program.

Corresponding parts of congruent parallelogram
Answer:
(a)Mean=9
(b)Median=9.5
(c)Mode=12
(d)Standard Deviation=2.53
Step-by-step explanation:
The sample of the number of vehicles that proceeded through the intersection after the light changed for 6 days during a 1 month period is given below:
6 12 7 12 8 9
(a)Mean
(b)Median
First, arrange in ascending order
6,7,8,9,12,12
Since we have two terms in the middle, we take the average.
(c)Mode
The mode is the number with the highest frequency. The mode number of cars is 12.
(d)Standard Deviation
Answer :
70 square units
Step-by-step explanation:
I have plotted the points on the coordinate system and connected roughly using a red line. Image is attached.
The arrow created, consists of a TRIANGLE and a RECTANGLE. The area of the arrow would be:
Area of Arrow = Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 * base * height
Base is 12 units
Height is 7 units, so
Area of Triangle = 0.5 * 12 * 7 = 42
Now,
Area of Rectangle = length * height
Length is 7
Height is 4
Area of Rectangle = 7 * 4 = 28
Area of Arrow = 42 + 28 = 70 square units
