So first I’m going to change the 10 kilometre in miles which is 6.214 miles
Then I’m going to convert 7800 seconds in hours which is 2.16 hours so now the data shows that Trisha biked 8 miles in 2 hours and becca biked 6.214 miles in 2.16 hours
So Trisha was faster than becca
Answer:
60 degrees
Step-by-step explanation:
The sum of the angles in a triangle are 180 degrees. The angles look the same size, so divide 180 by 3, and you get 60 degrees
The probability of finding 2 never married
10c2*0.4^2*0.6^8=
the probability of finding 1 never married
10C1*0.4*0.6^9=
the probability of finding 0 never married
10C0*0.6^10=
the answer is all the above answers added together.
think you can do the rest of the calculation by yourself. :)
btw nCr=n!/(n-r)!r!
good luck

~Brainliest would be appreciated
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
