Statistics

If you are counting each roll separately (if they are independentdent) then 1/6.

4 x 4 = 16.

If you multiply the last digit by 4: 6 x 4 = 24 (ends with 4).

Continue multiplying by 4, and you see that the last digit will always alternate between 4 and 6 - 4 for the odd powers, and 6 for the even powers.

So, in this case, the answer is 4.

48 * 100% = 4800%

It is a circular chart which is divided into at least two parts.

(9 x 8 x 7) = 504

It is 50/100 = 1/2

Values on the x axis is compared with values on the y axis and the line of best fit indicates a possible trend of the data collated.

The answer is 49C6 = 49*48*47*46*45*44/(6*5*4*3*2*1) = 13,983,816

Usually it would be on a stem all by itself, a long way from the next stem.

A lot of people have a difficult time getting over the red walls. This seems to mostly affect people on slower computers since timing is critical, and at slow frame rates it is hard to do the jump. The best way to get over these walls is to simply jump on top of one of the wooden blocks. Then jump again and start flying at the apex of the jump. You should now be able to just flyover the red wall.Many people have a hard time finding the marble. The passage to the marble is narrow, but there is a line of acorns marking the entrance. Just keep going to the end of the passage and the marble will be there.The correct way to do the marble bowling is to drop the marble and kick it into the batteries, however, you can also get a running start and just drop the marble. That will send it coasting into the batteries too, and this method is often more accurate than kicking.The slot car racing is really a no-brainer. Just hold down the throttle until the race is over - you'll win every time.

The answer depends on how many of the 5 cards are similar.

2 out of 12

The probability of rolling a 4 is 3/36 .

The propbability of rolling 12 is 1/36 .

The probability of rolling either one is 4/36 = 1/9 = 111/9 percent.

There is no such thing. Different measures are best in different circumstances.

If asked what the "central" colour of a car was, neither the mean nor median can even be calculated. You would not add a red car and a blue car to average at a purple car! On the other hand, you would have to be pretty lucky to find a mode for a continuous variable.

Similarly, one can come up with scenarios where the median or the mean beat the other two measures of central tendency hands down.

A matched test is appropriate only if the two variables are measures taken for the same subject.
