Answer:
As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
Step-by-step explanation:
Mean of the batch:
The mean of the batch is the sum of all values divided by the number of items. So

Mean in the desired interval.
Standard deviation:
Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
Answer:
k = -1/240
Step-by-step explanation:
to evaluate the value of k in the expression 1/3k+80=1/2k+120
we have
1/3k+80=1/2k+120
collect the like terms for easy evaluation
1/3k - 1/2k = 120 -80
1/3k - 1/2k = 40
find the lcm
2 - 3/6k = 40
-1/ 6k = 40
cross multiply
6k x 40 = -1
240k = -1
divide both sides by 240
240k/240 = -1/ 240
k = -1/240
therefore the value of k in the expression 1/3k+80=1/2k+120 is equals to -1/240

Answer: Rs. 100
Step-by-step explanation:
Given the following :
Total expenditure for dance show = Rs. 25000
Profit made except expenditure = Rs. 12,000
Number of people who observed and paid for the show = 370
Amount paid per person will be :
(Total amount or revenue realized / number of observers who paid)
Total revenue realized = (total expenditure + profit made)
Total Revenue realized = Rs.(25,000 + 12,000) = Rs. 37,000
Amount paid per observer = (Rs. 37,000 / 370)
= Rs. 100
