Answer:

(3,10)

Step-by-step explanation:

From f(x)=10 you can see that the value of y,which is equal to f(x), is 10.

Therefore, the only option you could pick is that where y=10,which is the case for option (3,10).

Step-by-step explanation:

total size of sample = 10,000

men women

voted 2777 3466

did not vote 1444 2313

By chi square test we can find the relationship between gender and participation in the election

$X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}$

where

a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

$X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}$

$X^2 = = 35.159$

Answer:

$75\sqrt{2}(\sqrt{3}-1)$

Step-by-step explanation:

In every right triangle, a leg is given by the multiplication of the sine of its opposite angle and the hypothenuse.

In this case, the opposite angle of x is 15°, and the hypothenuse is 300. So, we have

$x = 300\sin(15) = 75\sqrt{2}(\sqrt{3}-1)$
