Answer:
I believe your answer is 429.
Step-by-step explanation:
5 1/2 x 6 1/2 x 12 = 429
Answer:
here you go
Step-by-step explanation:
The relative frequency of an event is defined as the number of times that the event occurs during experimental trials, divided by the total number of trials conducted.
Relative frequencies are used to construct histograms whose heights can be interpreted as probabilities.
Formula to calculate relative frequency.
Twenty students were asked how many hours they studied per day. Their response was recorded in a frequency distribution table.
No. of Students. No. of Hours Studied. (Frequency)
2 3
4 2
5 1
1 7
3 5
5 6
To get the relative frequency in this case, we will take each frequency divided by the total frequency.
No. of Students. No. of hours (Frequency). Relative Frequency.
2 3 3 ÷ 24 = 0.125
4 2 2 ÷ 24 = 0.083
5 1 1 ÷ 24 = 0.042
1 7 7 ÷ 24 = 0.292
3 5 5 ÷ 24 = 0.208
5 6 6 ÷ 24 = 0.250
The sum of the relative frequency column should be 1.
Example:
Below is a frequency distribution table representing number of students absent in every grade.
Grade No. of students (Frequency)
Grade 1 10
Grade 2 5
Grade 3 4
Grade 4 6
Grade 5 3
Grade 6 2
Grade 7 1
Grade 8 2
Grade 9 1
Grade 10 1
The total frequency or the cumulative frequency in this case is 35. Therefore, to get the relative frequency, we divide each frequency by 35.
Grade No. of absentees (Frequency) Relative Frequency
Grade 1 10 10 ÷ 35=0.28
Grade 2 5 5 ÷ 35=0.14
Grade 3 4 4 ÷ 35=0.11
Grade 4 6 6 ÷ 35=0.17
Grade 5 3 3 ÷ 35=0.09
Grade 6 2 2 ÷ 35=0.06
Grade 7 1 1 ÷ 35=0.03
Grade 8 2 2 ÷ 35=0.06
Grade 9 1 1 ÷ 35=0.03
Grade 10 1 1 ÷ 35=0.03
The sum of the relative frequency is 1.
Answer: each salesperson sold 89 cars last year.
Step-by-step explanation:
The total number of sales people at the dealership shop is 13.
Last year they each sold the same number of cars. The total number of cars that they sold together last year was 1157. Therefore, the number of cars that each salesperson sold would be
Total number of cars sold/ number of salespersons
It becomes
1157/13 = 89
Answer:
5
Step-by-step explanation:
The mean represents an average of all the numbers, so we have 
. Although that may seem confusing, it's actually pretty easy.
We have a total of five numbers, which are 1, 6, 2, 7, and 9.
We add these numbers up to find the sum, so 1 + 6 + 2 + 7 + 9 = 25
So our final answer will be 
which can be simplified to 5.
