<h2>Circumference of flying disc is 34 inches</h2><h3><u>Solution:</u></h3>
Given that,
![Radius = 5\frac{2}{5}\ inches = \frac{27}{5}\ inches](https://tex.z-dn.net/?f=Radius%20%3D%205%5Cfrac%7B2%7D%7B5%7D%5C%20inches%20%3D%20%5Cfrac%7B27%7D%7B5%7D%5C%20inches)
To find: circumference
<h3><u>The circumference of circle is given as:</u></h3>
![C = 2 \pi r](https://tex.z-dn.net/?f=C%20%3D%202%20%5Cpi%20r)
Where, r is the radius of disc
Therefore,
![C = 2 \times 3.14 \times \frac{27}{5}\\\\C = 6.28 \times 5.4\\\\C = 33.912](https://tex.z-dn.net/?f=C%20%3D%202%20%5Ctimes%203.14%20%5Ctimes%20%5Cfrac%7B27%7D%7B5%7D%5C%5C%5C%5CC%20%3D%206.28%20%5Ctimes%205.4%5C%5C%5C%5CC%20%3D%2033.912)
![C \approx 34](https://tex.z-dn.net/?f=C%20%5Capprox%2034)
Thus the circumference of flying disc is 34 inches
Answer:
The Answere is 3 centimeters
Step-by-step explanation:
Google is an amazing professer
4 days
donvert 3 and 1/3 to imporopoer
3 and 1/3=3+1/3=9/3+1/3=10/3
divide 10/3 by 4
remember that divide by 4 means multiply by 1/4
10/3 times 1/4=10/12=5/6
each day spends 5/6 hour (about 50 mins)

Answer:
Step-by-step explanation:
Hello!
a)
The dependent variable is
Y: length of a dugong
The explanatory variable is
X: age of a dugong
You need to estimate the linear regression of the length of the dugongs as a function of their age.
Using the given data I've estimated the regression using a statistic software:
The regression model is E(Yi)= α + βXi
The estimated model is ^Yi= a + bXi
Where a is the estimate of the intercept and b is the estimate of the slope:
a= 2.02
b= 0.03
And the estimate of the population variance of the error is Se²= 0.03
The estimated regression equation is ^Yi= 2.02 + 0.03Xi
b)
You have to estimate the length of a dugong when its age is 11 years using the model, for this all you have to do is replace X=11 in the regression line and calculate the corresponding ^Y value:
^Yi= 2.02 + 0.03*11= 2.35
The average length of an 11-year-old dugong should be 2.35.
I hope it helps!
