(D) H_0H0: The direction of the ball and whether it results in a hit or an out are independent.
Step-by-step explanation:
Given that
There is 300 balls random sample is taken
We need to find out the appropriate null hypothesis that lies between the ball direction and lead to a hit or an out
So
Based on the given options, the option d is correct as the ball direction and its results either be hit or on out would represent that they are independent
Therefore the option d is correct

Answer:
Below
Step-by-step explanation:
You can use sine law to solve this : sina / A = sinb / B
We will first find side x
We know that since this is a special triangle that side will = 28, but we can prove this mathematically :
sin(45) / 28 = sin(45) / x
= 28 sin(45) / sin(45)
x = 28
Now to find side r just use Pythagorean theorem a^2 + b^2 = c^2 :
c^2 = 28^2 + 28^2
= 1568
Square root this number
r = 39.597
The just round to however your teacher wants
If you didn't already know about special triangles, an isosceles right triangle like this one has a ratio which is the two legs will equal each other, while the hypotenuse is √2a . You could have also used this to solve.
Hope this helps! Best of luck.
