What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375

426

Explanation:

To find the median number in a set of data start by reordering the data from least to greatest.

original data set:

593, 588, 540, 434, 420, 398, 390, 375

data set from least to greatest:

375, 390, 398, 420, 434, 540, 588, 593

Next, you would usually just have to find the middle number in the data set and that would be your median. However, this data set has no one number that is directly in the middle. So, we will add both middle numbers together and then divide our answer by two.

375, 390, 398, 420, 434, 540, 588, 593

420 + 434 = 854

854 ÷ 2 = 426

Therefore, the median of the given data set is 426.

b

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
