These figures?
well the most simple figures can be circle, triangle, square, etc... and you can write on how you got them.
Answer:
mean=4.44
standard deviation=1.67
Step-by-step explanation:
The mean and standard deviation for the number of erroneous returns per batch can be calculated using binomial distribution. The binomial distribution is used because
i) There are one of two possible outcomes( error or no error) that can be categorized into success and failure.
ii) The experiment is repeated fix number of times 12.
iii) The probability of success remains constant at each trial i.e. 37%
iv) The trails are independent.The mean and standard deviation of binomial distribution are np and √npq
Here, n=12, p=0.37 and q=1-0.37=0.63
mean=12*0.37=4.44
standard deviation=√12*0.37*0.63=√2.8=1.67
<span>Here is what you do.
Take the percentage you have and subtract it from 100.
100 - 22 = 78%
Now divide 12.48 by 78%

Answer:
HCF= 140 LCM=5880
Step-by-step explanation:
What I can really explain is how to find them. HCF is the Highest common factor, or what is the highest number that can be multiplied with another number to get 140 and 5880. It applies to BOTH numbers.
Lowest common multiple is the lowest number that when you count each number, both numbers reach the same point.
For example, the lowest common multiple between 2 and 3 is 6 because it is the lowest number where they meet.
2, 4, 6.
3, 6.
