How do you find the median

2 answers:

4 0

In a list of numbers, such as 1,2,3,4,5,6,7, start from the right and cross off the last number. In this case, it's the 7. Then, go to the left and cross of the first number, the one. Keep going from right to left, and when you get down to one number in the middle, that is the median. However if there are two numbers in the middle, I think that you have to find the mean of those two numbers, and that should be the median. That's only if there are two numbers left in the middle. Hope this helps!

The median is the middle score for a set of data that has been arranged in order of magnitude.

So order your vales, and then pick the middle record.

This works fine when you have an odd number of scores.

BUT

What happens when you have an even number of scores?

It is easy...

You would calculate the mean of the two middle records ..

in other words:
you simply have to add up the middle two scores and average the result.

I hope that helps!

The volume of a right square pyramid is 300 cubic units. If the area of the base is 50 square units, what is the height of the p

tresset_1 [31]

Answer: 18

Step-by-step explanation:

formula for volume of right square pyramid- area of the base * h/3 = volume

so, volume/ area of the base = 1/3 of height

300/50= 6. multiply your answer by 3 to get the full hight. 6*3= 18

your answer is 18 :)

A gardener wants to run a border around the outside of her garden. She plots it on a grid to plan how much she will

Karo-lina-s [1.5K]

Answer:

16 units.

Step-by-step explanation:

Just to make things easy, let's name the points A(3,9) B(5,9) C(3, 3) and D(5, 3).

Because this question wants perimeter, we'll just use the distance formula twice, then l*2 + w*2 = p.

Distance formula is sqrt((x1 - x2)^2 + (y1 - y2)^2) = d.

sqrt((5 - 3)^2 + (9 - 9)^2) = 2

sqrt((5 - 5)^2 + (9 - 3)^2) = 6.

The distance of points A and B is 2 units, and B to D is 6 units, multiply both by 2, (2*2=4, 6*2=12) and add the values to find 16 units.

Hope this helps, and if this is for OW, I feel your pain.

It takes Mike 1 hour to get to work each day. He first rides the train, which travels at an average rate of 65 miles per hour. T

Answer:

Time_subway = 6 minutes

Step-by-step explanation:

Total time to get to work = 1 hour

Total_distance = 61 miles

Speed_train = 65 miles/h

Speed_subway = 25 miles/h

The fomula for speed is defined as

Speed = distance/ time, which means that

Time = distance/speed

Total_time = time_train + time_subway

Total_time = (distance_train/Speed_train) +

(distance_subway/Speed_subway )

1h = (distance_train/65) + (distance_subway/25 )

We also know that

Total_distance = 61 miles = distance_train + distance_subway

We solve the system of two equations

1 = (distance_train/65) + (distance_subway/25 )

61 = distance_train + distance_subway

We obtain that

distance_train = 58.5 miles

distance_subway = 2.5 miles

So the time spent on the subway is

t_sub = (2.5 mi/25 mi/h) = 0.1 h

0.1 h is equal to 6 minutes

*plis need it* A cattle breeder sold ¾ of his cows. After that, he sold ¾ of the remainder, and there are 16 cows left. How many

Tju [1.3M]

Answer:256 cows

Step-by-step explanation:

Let the total cow be a

3/4 of a

3/4 x a=3a/4

Remainder= a-3a/4=a/4

Remainder=a/4

3/4 Of The remainder

3/4 of a/4

3/4 x a/4=3a/16

New remainder will be

a/4-3a/16=a/16

New remainder is a/16

Therefore: a/16=16

Cross multiplying we get

a=16x16

a=256
