(X1=1, y1=7) and (x2= -4, y2 =-8)

Slope = ( y2-y1)/(x2-x1)= (-8-7)/(-4-1)= -15/-5=3

Slope is 3

Answer:

Correct option: A. P=0.057

Step-by-step explanation:

Binomial Distribution

The binomial distribution fits the case of n independent events each one with a probability of success equal to p where k successes have been achieved.

The PMF (Probability Mass Function) of the binomial distribution is

$\displaystyle P(k,n,p)=\binom{n}{k}p^kq^{n-k}$

Where $q = 1-p$

The individual probability that an electronic device does not function properly is p=0.1. We know n=10 devices have been bought and we want to compute the probability that 7 devices function properly. Please notice that this is not the value of k since p is the probability of failure. The correct value of k=10-7=3. The required probability is

$\displaystyle P(3,10,0.1)=\binom{10}{3}0.1^30.9^{10-3}$
