Why Do we go to school ? What is the point of Homework ? Will we be any better than anyone else if We have Qualifications ?


Are you any better off because someone taught you to speak? Or to read? School is a place where we share what we have learned throughout history so that we don't, like lesser animals, have to rely on instinct and figure out everything on our own. The things you learned helped you survive to retirement. Maybe you don't need them now that you are retired (as am I) but they helped you along the way. I am 73 and still studying Spanish, German, and the guitar.

Mophie charger plug wont stay in


I had the same issue. I was able to trim the cable shell to get it to insert further and take better hold. I suspect some cables may work better than others but the design is poor as they have the jack on a curved corner. Had they angled it a little it would work better and actually work. They should also include a screen protector for the price. The case scrapes off standard protectors because of the tight fix, though the tight fit is good. I actually love the product though as it actually works. Just not enough real world testing.

The following frequency distribution analyzes the scores on a math test. find the indicated class midpoint or boundaries. 40-55 2 60-75 4 76-82 6 83-94 15 95-99 5


Midpoints ( x + y)/2 = x47.567.57988.597

Boundaries for lower class -0.5 and +.0.5 for upper.39.5 - 55.559.5 - 75.575.5 - 82.582.5 - 94.594.5 - 99.5
I just don't get how the number of students factor in? It's still an average.

M5010 - Tested DC Jack (PC wont turn on at all) and i noticed it shows 1.7V instead of 1.9V Is it bad?


The Dell Inspiron laptop mains adapter output voltage is 19 volts.
If your adapter has an output voltage of 1.7 volts then the adapter is faulty and you need to purchase a new one.

Can I convert sienna 2008LE 7 passenger to 8 passenger


Changes the rules for the tags and the driver license. 8 and up require a CDL to driver in the USA. where do you think your going to put the extra person anyway. the seat has to have an approved place in the seat, the vehicals suspenstion has to be able to carry the extra whieght. the air bag system has to be tested and approved for the extra person. And no one person is better than another ( supossedly) than another, or less for that matter. All seats and seatbelt and crash worthyness has to be tested by the manufacturer and then certified by the governmnet in the country that the vehical is used and the go past the limit of license will certainly challange this rule. from 5-6 doesn't break any rules but from 7-8 the total required vehical wheight comes into play and the heavier vehical requirs special licenses and crashworthy ness. There are special rules for sbhool buses and the requirments for their drivers are different still and are sometimes left to local governments to decide. These buses are most likly operated by the governmnet so the rules can be bent in the area of cost. I rode to school a few miles standing in the isles holding a seat back as I went to school in the 60's but I don't thnk they allow overoverloading anymore. no mattrer who owns the bus.

No dial tone at any jack. (12 total, 11 are home runs, one is and extension from a jack box) Disconnected each phone, problem still present. Have a dial tone at the NID. Tested each jack with the...


You can use an ohm meter or a continuity meter to test the wiring but the regular phone will work ok. The next step is to disconnect all the internal house wiring from the NID and then replace them one at a time. After you replace a wire test all the jacks to see if the dialtone is on a jack. When you connect the bad wire/jack it will short out the jacks that were working on the previous tests. Then leave the faulty wire/jack disconnected from the NID and reconnect the remaining wires. The jack thats not working is the faulty wire.

RCA 60" Rear Projection TV Model P60925bl TV screen curved on the top and bottom. Colors are not aligned and images are blurred.


this would be the convergence IC 's that need replacing
if you are going to have a tech come out to do the repair it will cost between 3 or 4 hundered dollars
if you are going to do the repair yourself ( meaning that you can solder and indentify the convergence chips and test the resitors on it) then it will cost about $40 or so
