It is known that 60% of all brand a external hard drives work in a satisfactory manner throughout the warranty period (are "successes"). suppose that n = 15 drives are randomly selected. let x = the number of successes in the sample. the statistic x/n is the sample proportion (fraction) of successes. obtain the sampling distribution of this statistic. [hint: one possible value x/n is 0.2, corresponding to x = 3. what is the probability of this value (what kind of random variable is x)? ] (round your answers to three decimal places.)

3x + 4y -25 =0 represents the amount of change sianna should recieve

you just switch the numbers basically so it would be 3/17

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

since there are the same amount of marbles of getting a blue one wold be low as far from that it would also be low!
