Topic: Measures of Central Tendency Subject: Statistics In an exam scored from 0 to 10, 3 people obtained a 5 mark, 5
people got 4 marks, and 2 people got 3 marks. Calculate
the average note and the median.

the answer is 62

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
