Airlines have increasingly outsourced the maintenance of their planes to other companies. A concern voiced by critics is that th

e maintenance may be less carefully done so that outsourcing creates a safety hazard. In addition, flight delays are often due to maintenance problems, so one might look at government data on percent of major maintenance outsourced and percent of flight delays blamed on the airline to determine if these concerns are justified. This was done, and data from 2005 and 2006 appeared to justify the concerns of the critics. Do more recent data still support the concerns of the critics? Here are data from 2014:

According to the information that is found in a different source, the recent data does not support the concerns of the critics. These are the numbers shown in the data:

<u>Airline / Outsource Percent / Delay Percent</u>

<em>Alaska</em> / 51.0 / 10.35

<em>American</em> / 29.4 / 20.32

<em>Delta</em> / 36.7 / 14.48

<em>Frontier</em> / 46.3 / 21.42

<em>Hawaiian</em> / 78.4 / 5.06

Based on this data, we can see that the critics do not seem to be justified in their concerns. We can see that airlines have outsourced much of the maintenance of their planes, but that there does not seem to be a strong correlation between this outsourcing and the percentage of delays. For example, the airline that outsources the most is Hawaiian (78.4%), yet it has the lowest percentage of delayed flights (5.06%).

Answer:

<h3>1. t=10</h3><h3>2. t=4</h3><h3>3. t=40</h3>

Step-by-step explanation:

Isolate the term of t from one side of the equation.

<h3>1. 4t=40</h3>

First, you have to divide by 4 from both sides.

4t/4=40/4

Solve.

Divide the numbers from left to right.

40/4=10

<h3><u>t=10</u></h3>

<h3>2. 10+t=14</h3>

<u>First, change sides.</u>

t+10=14

<u>Then, subtract by 10 from both sides.</u>

t+10-10=14-10

<u>Solve.</u>

<u>Subtract the numbers from left to right.</u>

14-10=4

<h3><u>t=4</u></h3>

<h3>3. 70-t=30</h3>

First, subtract by 70 from both sides.

70-t-70=30-70

Solve.

30-70=-40

<u>Rewrite the problem down.</u>

-t=-40

Divide by -1 from both sides.

-t/-1=-40/-1

<u>Solve.</u>

<u />

<u>Divide the numbers from left to right.</u>

-40/-1=40

<h3><u>t=40</u></h3>

  • <u>Therefore, the correct answer is t=10, t=4, and t=40.</u>

I hope this helps! Let me know if you have any questions.

Mariulka [41]

Answer:

24 students

Step-by-step explanation:

Since students on opposite sides of the circle are 30 feet apart, the circumference of the circle is πd≈94.2. Since each student takes up 4 feet of space, 94.2/4=23.55 which we can round to 23 or 24 students.
