Answer:(1) 33% (2) 27% (3) 33% (4) 48% (5) 33% (6) 35% (7) there is a difference because theoretical is statistics and logistics while experimental probability is randomized as and answer
Step-by-step explanation: you have three options of you two coins to land so if you were to divide that by 100 you would get .333333 so on and so forth and putting that to percent is 33% then on the experimental probabilities it was the number of times it landed divided by 100
Answer:
Mailing preparation takes 38.29 min max time to prepare the mails.
Step-by-step explanation:
Given:
Mean:35 min
standard deviation:2 min
and 95% confidence interval.
To Find:
In normal distribution mailing preparation time taken less than.
i.eP(t<x)=?
Solution:
Here t -time and x -required time
mean time 35 min
5 % will not have true mean value . with 95 % confidence.
Question is asked as ,preparation takes less than time means what is max time that preparation will take to prepare mails.
No mail take more time than that time .
by Z-score or by confidence interval is
Z=(X-mean)/standard deviation.
Z=1.96 at 95 % confidence interval.
1.96=(X-35)/2
3.92=(x-35)
X=38.29 min
or
Confidence interval =35±Z*standard deviation
=35±1.96*2
=35±3.92
=38.29 or 31.71 min
But we require the max time i.e 38.29 min
And by observation we can also conclude the max time from options as 38.29 min.
Answer: slopes will be the same!
Step-by-step explanation:
The equation that best represents the total earnings for the salesman is letter c which is e=40,000+200 xc
It is because, in order to get the full earnings, you have to add the base salary to the commission that the salesman receives. Whereas, the $40,000 is attached to the commission where the $200 is multiplied to c (every car the salesman sells
The value of 7 is 7 because it is in the ones place
