How do you find the median of a set of odd numbers?

It would be the middle number of a set of numbers or data in numerical order

What is the probability of getting a sum of 5?

Assuming you mean when rolling 2 dice, the probability is the number of ways of getting the sum of 5 over the number of possible outcomes.

4 ways of getting 5 (1+4; 2+3; 3+2; 4+1)

36 outcomes (6 x 6)

the probability is 4/36 = 1/9

Two cards are drawn from a pack of 52 cards at random. Then one card is drawn from the remaining 50 cards. What is the probability that it is an ace?

There are 4 possible outcomes yielding an Ace on the third draw without replacement:

a) Ace and Ace (first two cards) then Ace (third card) = 4/52 x 3/51 x 2/50 (24/132600) or

b) Non-ace and Ace then Ace = 48/52 x 4/51 x 3/50 (576/132600) or

c) Ace and Non-ace then Ace = 4/52 x 48/51 x 3/50 (576/132600) or

d) Non-ace and Non-ace then Ace = 48/52 x 47/51 x 4/50 (9024/132600)

Then it's just a+b+c+d

(24+576+576+9024) / 132600

=10200/132600

=0.0769 (about 7.7%)

or more simply 4/52 if you're in a hurry because the oolongteasup

If the first three angles of a square are right how is the fourth wrong?

it is not because then it wouldn't be a square.A square equals 4 90 degree angles and 4 equal sides.

How do you add oil to the front end on a 1989 Toyota pickup 4X4?

there should be a drain fill plug on the front your diff. Since you have the IFS probably the easierst way to get oil into it would be to use along piece of fuel line from the top of your engine to the fill plug and just fill it from under the hood rather fan fighting with the bottle underneith the truck.

Is a median number higher than a mean number?

Imagine that you have a list of 15 numbers for example. The mean is the average of those number. In other words, take the sum of all the numbers and divide by how many numbers there are (15 in this case). The median is the "middle number," and is found by arranging all the numbers in order of size and then picking the middle number. If you have 15 numbers, the 8th number is the middle one (there would then be seven smaller numbers and seven larger). If instead you have an even number of numbers, then you don't have a single middle number (you have two), and so you would take the average of the two middle ones (for example, if you have 16 numbers, you take the average value of the 8th and 9th numbers as the median). Whether the median or the mean is larger depends entirely on the specific list of number that you are analyzing.

Define equipment error and explain how to reduce it?

the equipment error is the percentage of uncertainty on the equipment, so for example, a measuring cylinder has the percentage error of around 0.5cm3. The only way I know off to reduce error percentage is to well increase sample size/ volume A etc. as the calculation is something like (equipment error / quantity measured x 100) this would mean that having a higher quantity to measure will therefore decrease percentage error. hope it helps.

What is the range of the numbers -5 4 -7 5 13?

Range = 20.

The range is the difference between the largest value and smallest value in a population, and it roughly shows dispersion. For this case, it is 13 - (-7) = 20. For small population sizes, the range is not a good statistic.

What is smaller decimeter or meter?

Deci means tenth, so decimeter would be a tenth of a meter. Decimeter is smaller then.
