Answer:
186
Step-by-step explanation:
The sample mean, x, is the central value in the confidence interval, that is, the average between the upper and lower bounds of the interval.
In this case, the Lower bound is 184.00 and the upper bound is 188.00. Therefore, the sample mean is given by:

The mean length, in seconds, of the sampled songs is 186.00.
For this case we have the following equation:

From here, we must clear the value of x.
For this, we follow the following steps:
1) Place the variable on one side of the equation and the constant on the other side of the equation:

2) Make common factor x:

3) Clear the value of x:

Answer:

The relationship between x and the difference of a - b is inversely proportional.

Answer:
boys=432 girls=528
Step-by-step explanation:
11b=9g
g=b+96
11b=9(b+96)
11b=9b+864
11b-9b=864
2b=864
b=432
g=432+96
g=528
The absolute value of any number will always be a positive number. That is the definition of an absolute value. It is usually denoted by the || bar. For example, when you want to find the sum of 1 and ⁻5, you write it as |1 + ⁻5|. Even though the actual answer is ⁻4, because it is in absolute value, you'll report it as +4 instead.
