Answer:
Step-by-step explanation:
Left skewed
2 and 3
Put it on the graph as 2xy=10!
Answer: 1 and 3
It's because they both divide down lower than 1
Answer:
They use 741 dollars
Step-by-step explanation:
Write 65% as
65/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
65/100 of 1140 = 65/100× 1140
Therefore, the answer is 741
If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.
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
