Answer:
$50.83
Step-by-step explanation:
44.20 x .15 = 6.63
44.20 + 6.63= 50.83
5. C. Liquid 2 because 3ml = 1g, 6ml = 2g
6 C. Lead because 75.7 divided by 6.7 = 11.3
7. C. Copper because 89 divided by 10 = 8.9
What is the mean, median, and mode of 6,2,3,4,4,2,8,5,2
bearhunter [10]
Answer:
Mode=2
Median=4
Step-by-step explanation:
Mode you add all the numbers and divide by the actual number of the numbers given.
Median you cancel the numbers from first to last until you reach the one in the middle that's going to be the median.
Answer:
So we can find this probability:

And then since the interest is the probability that the mean diameter of the sample shafts would differ from the population mean by more than 0.3 inches using the complement rule we got:

Step-by-step explanation:
Let X the random variable that represent the diamters of interest for this case, and for this case we know the following info
Where
and
We can begin finding this probability this probability
For this case they select a sample of n=79>30, so then we have enough evidence to use the central limit theorem and the distirbution for the sample mean can be approximated with:

And the best way to solve this problem is using the normal standard distribution and the z score given by:
And we can find the z scores for each limit and we got:
So we can find this probability:

And then since the interest is the probability that the mean diameter of the sample shafts would differ from the population mean by more than 0.3 inches using the complement rule we got:
