The lower bound of the measurement is 65.5 millimetres.
A centimetre equals 10 millimetres, a measure is expressed by the <em>measured</em> magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:
(1)
Where:
- Measured magnitude, in millimeters.
- Possible magnitude, in millimeters.
- Uncertainty, in millimeters.
If we know that 
and 
, then the lower bound of the measurement is:
The lower bound of the measurement is 65.5 millimeters.

Hey there! :)
The answer is 80%
6 ÷ 30 = 0.2 = 20%
100 - 20 = 80
Hope this helped :)
Division using multiples of 10 is different than how most of us learned how to divide. <span>The idea of multiple is what number can 10 go into without a remainder. That is easy. Ten ends in a zero. Thus 10 goes into numbers ending in zero. An example is 60. Ten ends in a zero; 60 ends in a zero. It will divide evenly. </span>

Step-by-step explanation:
5 times a number is 5x
increase means add
Answer:
C.I. = (2.297, 11.703)
Step-by-step explanation:
The t-statistic for difference of mean is given by,
Here, 
= 84
= 7
s₁ = 4
n₁ = 12
s₂ = 6
n₂ = 18
Substituting all value in formula,
We get, t = -3.541 at 28 degree of freedom.
Using this formula, we get, t = 1.5342
Therefore, based on the data provided, the 99% confidence interval for the difference between the population means 
is: 2.297 < < 11.703
which indicates that we are 99% confident that the true difference between population means is contained by the interval (2.297, 11.703)
