Answer:
Step-by-step explanation:
We need to find out the value of sinC using the given triangle . Here we can see that the sides of the triangle are 40 , 41 and 9 .
We know that the ratio of sine is perpendicular to hypontenuse .
Here we can see that the side opposite to angle C is 40 , therefore the perpendicular of the triangle is 40. And the side opposite to 90° angle is 41 . So it's the hypontenuse . On using the ratio of sine ,
Substitute the respective values ,
<u>Hence the required answer is 40/41.</u>
Answer:
30
Step-by-step explanation:
If there are 5 for every 6, then you divide 36 by 6 and then you get 6
Once you get that, multiply 5 by 6 and get 30

To find whether there is an association between these two let us find the correlation coefficient between these two variables.
r=-0.1975
Since |r|<0.5, correlation is weak.
Let us test the hypothesis r =0
H0:r=0
Ha:r not equals 0
Test statistic = ![\frac{r\sqrt{n-2} }{\sqrt{1-r^2} } \\=\frac{-0.1975\sqrt{11-2} }{\sqrt{1-0.1975^2} }\\=\frac{-0.5625}{{0.9803} } \\=-0.5738](https://tex.z-dn.net/?f=%5Cfrac%7Br%5Csqrt%7Bn-2%7D%20%7D%7B%5Csqrt%7B1-r%5E2%7D%20%7D%20%5C%5C%3D%5Cfrac%7B-0.1975%5Csqrt%7B11-2%7D%20%7D%7B%5Csqrt%7B1-0.1975%5E2%7D%20%7D%5C%5C%3D%5Cfrac%7B-0.5625%7D%7B%7B0.9803%7D%20%7D%20%5C%5C%3D-0.5738)
p =0.298
Since p value >0.10, at 90% significance level we accept that there is no association.
Answer:
b. 2 feet
Step-by-step explanation:
The formula for volume of a cylinder is: V=πr^2h
Start by plugging in what they give you
V=πr^2h
314 =π(r)^2(25)
314 = 25π(r)^2
divide both sides by 25π, which is 78.5
4 = r^2
take the square root of both sides
r = 2
