Answer:
Function
Step-by-step explanation:
The following is a <em><u>one-on-one function</u></em> since neither the domain nor the range is being repeated.
I would say B.
Because 21x8.2=172.2
And then I learned that you only divide the area by 2 so I say B
-1,3 because your moving the quadrant counter clockwise into the 2nd quadrant
Answer:
95%
Step-by-step explanation:
For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level, wider will be the confidence interval.
This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.
The confidence interval for a population proportion is given by the formula:
So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.
Hence 95% confidence interval will be wider than 80% confidence interval.
To have a width of 3.5 ft we have to divide 10.5 by 3
If we do the same and divide 12 by 3 we get 4ft length
so the area of the scale model is 3.5 * 4 = 14 ft
