Answer:
That doesn't make sense, it's wrong. t=60 because 45+15=60
Step-by-step explanation:
Here you have the solution. If you are interested in the law which I have used here, you can read about countinuity of fluid principle.
Answer:
60
Step-by-step explanation:
we know that it is less then 90 degrees so it can't be 110 and 70 degrees would be more extended from the horizontal line
Answer:
6
Step-by-step explanation:
This is calculated as using z score
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Hence,
We find the z score of 95.44% confidence interval
95.44% = 1.9991
Hence.
1.9991 = ( X = 22) - (X = 10)
1.9991 = (22 - 16/ σ) - (10 - 16/ σ)
1.9991 = (6/σ - (-6/σ)
1.9991 = ( 6/σ + 6/σ)
1.9991 = (6 + 6/σ)
1.9991 = 12/σ
Cross Multiply
= 1.9991 × σ = 12
σ = 12/1.9991
= 6.00270121555
Approximately 6
Hence, the standard deviation is 6
