Answer:
It would take 10 days for 2 people working for 5 hours a day to fix a road.
Step-by-step explanation:
Given:
Let the number of people be denoted by 'p'.
Let the number of hours be denoted by 'h'.
Let the number of days be denoted by 'd'.
Solution:
Now given:
Case 1:
It take 10 people working 2 hours a day 5 days.
so we can say that;
Now we can say that.
Job Completed can be calculated by multiplying number of people with number of hours and number of days.
So we can say that;
Job Completed =
Case 2:
We need to find the how many days will it take 2 people working 5 hours a day to fix a road.
So we can say that;
Now we know that;
Job Completed =
Now we know that Job completed would be the same so we can say that;
Dividing both side by 10 we get;
Hence we can say that It would take 10 days for 2 people working for 5 hours a day to fix a road.
I think that would be the last one
Answer: B. Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.
Step-by-step explanation:
Given the following list of data:
83 45 80 53 46 24 79 34 55 10 44
Range :
(Highest - Lowest) value
83 - 10 = 73
Sample Variance :
[Summation of (x - mean)^2] / number of observation - 1
Mean = (83+45+80+53+46+24+79+34+55+10+44) / 11
= 553 / 11 = 50.3
Check attached picture for computation of variance and standard deviation.
In football, jersey numbers do not imply any statistical relevance or importance
Answer:
0.5 x 10^3
Step-by-step explanation:
(2.5 x 10^7) /(5 x 10^4)
Divide 2.5 by 5 and subtract the powers. We are subtracting the powers because we are dividing. If we were multiplying, we’d add the powers .
This can be written as
2.5/5 x 10^7-4
0.5 x 10^3
