The answer is A.
Explanation:
Since this is a right triangle you can use The formula: leg squared plus leg squared = hypotenuse squared
So lets square the hypotenuse and first leg
And you get 85 hypotenuse and 49 leg
So just subtract 49 from 85 to get the other leg squares
You get 36 so now just square root it
Square root of 36 is 6
So the best answer is 6

Answer:
What's '2−7x'
Step-by-step explanation:
Step-by-step explanation:
Consider the provided information.
Part (A) We need to find the confidence coefficient.
The given value or percentage of probability is known as the confidence coefficient that the interval contains the parameter.
Hence, the confidence coefficient is 0.90
Part (B) Practical interpretation of both of the 99% confidence intervals.
It means that there is 99% confident that the mean of population HRV for officers diagnosed hypertension which lies between 6.9 and 122.9
There is 99% confident that the mean of population HRV for officers those are not hypertensive which lies between 144.2 and 184.9.
Part (C)
If you are saying 99% confident that means the 99% of the similarly generated confidence intervals will contain the true value of the population mean in repeated sampling.
Part (D)
If We want to reduce the width of each confidence interval, you need to use smaller confidence coefficient.
B) the additive inverse of -3 is +3, so 17-(-3) = 20 is your answer.
Remember, two negatives = one positive, and so:
- (-3) = 3
17 + 3 = 20
Therefore, B is your answer
hope this helps
