Use the midpoint formula
(x1 + x2/2, y1 + y2/2)
Input the corresponding numbers
(-12 +5/2, 3 + -10/2)
(-7/2,-7/2)
So, the midpoint of the line segment is (-7/2,-7/2)
60u=15 litres
1u=15l÷60
=0.25l
40u=0.25l×40u
=10l
Ans:10 litres of paint thinner
Step-by-step explanation:
I think 5/21 is the answer when you multiply 5/12 and 12/21
You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.
