Answer:

Step-by-step explanation:
simplify
by putting the negative sign on the outside. 
find the LCM of the denominators. It is (x-1)(x-2). Multiply by the LCM:

Simplify:

solve: 
1: 2/5=emails 3.6hrs=emails, 3.6=2/5 5-2=3 3.6•3=__hours of work
2. 294+83=$__
3. 3•x=hw 64/4=__•3=__hrs on math
4. Idk sorry
Sorry if some of these are wrong but I'm pretty sure there right.
Answer:
- strong negative linear correlation
- -0.986
Step-by-step explanation:
You need to notice that when altitude goes up, temperature goes down. That means the correlation is negative.
The table shows the temperature decrease to be monotonic (nowhere does it go up when altitude increases), so the correlation is strong.
The strong negative correlation number available to you is -0.986.
___
If you want confirmation, you can put the numbers into your favorite graphing calculator and tell it to compute the correlation for you.
Answer:
1,338.75 miles in 3.5 days.
Step-by-step explanation:
What I did was first, 765/2=382.5
Then I did 382.5x3.5=1338.75(rounded 1339 or 1340)
Hope this helps.
For this case we have:
Let x be the variable that belongs to the real numbers. Then, all reals less than 70 can be expressed as:

The tip of the inequality is directed to the real numbers, since they tell us that they are less than 70, for 70 the inequality remains open.
