I dont get it im confusid here
What are the mean, median, mode and range of the following data set?9, 3, 4, 4, 4, 3, 2, 2, 20, 20?

Answer:
mean: 7.1
mode: 4
median: 4
range: 18
Step-by-step explanation:
If the area is 30 inches, then the length must be 5 and the width must be 6, so 10+12=22 which is your perimeter. I got 10 with 5x2 and 12 with 6x2. Then you add it together because the formula for perimeter is (lengthx2) +(widthx2)! Just in case you need an explanation.
10,10 and 20 cannot as 10+10=20 so there would be a triangle with no area.
The others can all be the sides of a triangle as 7+7>8, 7+6>11 and 2+8>9.
The probability of he/she is a technician or production operator will be 7/8.
<h3>What is probability?</h3>
The probability of an event occurring is defined by probability.
If you flip a coin, the likelihood that it will land on its head or tail is nothing more than the chance that either the head or the tail will occur.
Given,
Event 1 = selection of technician
Event 2 = selection of production operator
Since both events are independent and nothing has common in between
So,
P(1 or 2 ) = p(1) × p(2)
So,
probability (technician or production operator) = probability of technician × probability of production operator.
Probability (technician or production operator) = 10/40 + 25/40 = 7/8
Hence the probability of he/she is a technician or production operator will be 7/8.
