Answer:
mean is basically the average, you add all the values togheter and then divide the sum by the number of values
the median is the number in the middle if you put all the values in the correct order from least to greatest.
mode is the value that's repeated the most! hope this helps!
Step-by-step explanation:
0.75 is the possible answer, if not its probably 12 :)
Answer:
0.677
Step-by-step explanation:Add up the values in the plan A column. There are 10+12+16 = 38 people who prefer plan A.
Add up the values in the "40-49" row to find that 16+8 = 24 people are ages 40 to 49.
We have 38+24-16 = 46 people who either prefer plan A, are aged 40-49, or fit both descriptions. I subtracted off 16 because those 16 people were counted twice when adding 38 and 24.
An alternative way to get this value of 46 is to add up everything that is in column1 or row 3 (or both). So that would get 10+12+16+8 = 46.
Now add up everything in the table to find out how many people were surveyed total. That would be 10+7+12+15+16+8 = 68 people overall.
The probability of someone liking plan A, or being age 40-49, or both is 46/68 = 0.6765 approximately. Rounding to 3 decimal places gives 0.677

using a graph tool
see the attached figures
case A)
y>x+1
y<=10
x>=0
case B)
y>=x+1
y>=10
x>=0
case C)
y>=x+1
y<10
x>=0
case D)
y<x+1
y<=10
x>=0
the answer is the case A)y>x+1 y<=10x>=0
200,000 milligrams is the correct answer
