Answer:

Median = 116.

First quartile = 102.

Step-by-step explanation:

There is a total of 280 scores so the median will be the 140th score.

The first box gives 26 , second 34 = 60

The 3rd box contains 100 giving a total of 160 so the median lies in this third box.

140 - 26 - 34 = 80..

That gives a value of 80 / 5 = 16.

The median is 100 + 16 = 116.

The lower quartile is the 70th score

26 + 34 + 10 = 70.

So it is 100 + 10/5 = 102.

How many models of 100 do you need to model 3200 explain

rusak2 [61]

32 models need to make model of 3200.

Given that a 1 model contain 100.

Two series of numbers, usually empirical data, that are proportional or proportional if their respective elements are in constant proportion, called the scaling factor or the rate constant.

One model has 100 elements.

Now, we have to find how many model contains 3200 elements.

So, 1 model=100 elements

n model =3200 elements

We will write this in proportion as

1/n=100/3200

Applying the cross multiply, we get

3200×1=n×100

Divide both sides with 100, we get

3200/100=100n/100

3200/100=n

32=n

Hence, the 32 models contain 3200 elements when one contain 100 elements.
