Answer:
We can calculate range and mean by the following WAys
Step-by-step explanation:
Range = largest number - smallest number
= 1200 - 800
= 400
Now
Sum of the data = 1200+1150+950+900+800+1000=6000
Number of data = 6
Now Mean = sum of the data / Number of data
= 6000/6
= 1000
Answer:
23/2 is already in the simplest form. It can be written as 11.5 in decimal form
Step-by-step explanation:
23 2 = 22 2 + 1 2 = 11 + 1 2 = 11 1 2
This fraction cannot be simplified any further because there is no common divisor for 1 and 2 other than 1
This is a right triangle equation
so a^2 + b^2 = c^2
c^2 is the hypotenuse and the 15 feet
a^2 + 9^2 = 15^2
a^2 + 81 = 225
a^2 = 144
the square root of 144 is 12
the tree is 12 feet tall
Answer:
2:5
Step-by-step explanation:
c : a : a²
8 5 7
add 8 + 5 + 7 = 20
comedies = 8
8:20 | factors of 8 and 20 are 4
8 / 4 = 2
20 / 4 = 5
new ratio; 2:5
