Answer:
1= 1
2=11
3=7
Step-by-step explanation:
subtract 6 from the input so
7-6=1
11-6=5 so input 11
13-6=7
Answer:
240- 360
Step-by-step explanation:
You have to find out how many minutes in an hour which is 60. Then multiply it by 2 for 2 hours to get 120. Then you multiply 2x120 to get 240. Then you multiply 3x120 to get 360.
I'm not sure if this is correct but this is how I would go about it. :)
Answer:
x=12
Step-by-step explanation:
This is an equilateral triangle. That means all the angles are equal
There are three angles and they add to 180. 180/3 =60. Each angle is equal to 60
4x+12 =60
Subtract 12 from each side
4x+12-12 = 60-12
4x = 48
Divide by 4
4x/4 =48/4
x=12
Answer: 
Step-by-step explanation:
Given : Sample size : 
, which is a small sample (, 30) so we use t-test.
