saw5 [17]

Answer:

it is clear that at 95% confidence that the bonus plan has increased the sales significantly, because if we observe you will notice that sales after is greater than sales before in all six cases.

when camping alone , mr adam uses all of the water in 12 days, then when mrs adams and mr adams camp together they use all of th
professor190 [17]

Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.

<h3>What is the together rate?</h3>

The together rate is the sum of each separate rate.

In this problem, the rates are:

  • Together: 1/8.
  • Mr Adam: 1/12.
  • Mrs Adams: 1/x.

Hence:

\frac{1}{12} + \frac{1}{x} = \frac{1}{8}

\frac{x + 12}{12x} = \frac{1}{8}

12x = 8x + 96

4x = 96

x = \frac{96}{4}

x = 24

If Mrs Adams camps alone, she will use all the water in 24 hours.
