Answer:
(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:
x=6
Step-by-step explanation:
We know that point C is in the middle of point A and point B.
That means that when these two equations are added they should be equal to the length of AB which is 41.
5x+3x-7=41
add 7 to both sides
8x=48
divide both sides by 8.
x=6

Answer:
The probability of failure of both the bulbs is 0.4323.
Step-by-step explanation:
For an exponential distribution the distribution is given by
The value of λ is related to the mean μ as λ=1/μ,
Let us denote the 2 bulbs by X and Y thus the probability distribution of the 2 bulbs is as under
Similarly for the bulb Y the distribution function is given by
Thus the probability for both the bulbs to fail within 1500 hours is
