Answer:
1 hour = 7.50
5 hours = 37.50
9 hours = 67.50
<h3>
answer is</h3>
7.50 per hour.
97.50 = 13 hours
Step-by-step explanation:
like this
or
= 7.50/1 hour
hope it helps you ☺️
Answer:
v avg=(x2-x1)/(t2-t1)
(the numbers are subscripts)
v avg = average velocity (m/s)
x1 = the start position of an object (m)
x2 = the end position of an object (m)
t1 = the start time of the motion (s)
t2 = the end time of the motion(s)
<h2><u>
Answer with explanation:</u></h2>
Formula to find the confidence interval for population mean :-
, where = sample mean.
t*= critical z-value
n= sample size.
s= sample standard deviation.
By considering the given question , we have
n= 50
Degree of freedom : df = 49 [ df=n-1]
Significance level :
Using students's t-distribution table, the critical t-value for 95% confidence =
Then, 95% confidence interval for the population mean will be :
Hence, a 95% confidence interval for the population mean = (24.24, 27.76)
Since 28 is not contained in the above confidence interval , it means it is not reasonable that the population mean is 28 weeks.
150x1.28 would be 192. the answer would be 192 because you would first find 28% of 150 and then add that to 150 or you can multiply 150 and 1.28 to get 192.
hint= the decimal form of 28% would be .28
