Add them all up: 86+90+93+85+79+92=525
divide by 6 (because they provide 6 percentages): 525/6
mean=87.5
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
Answer:
mean= m7.8571428571429 Mode 1, 2
Step-by-step explanation:
The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores. The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
