The lifetime of bacteria follows the Weibull distribution. The probability that the bacteria lives for more than 10 hours is 0.6 and that it lives more than 20 hours is 0.3. We want to find the probability that among 300 bacteria more than 200 live longer than 10 hours. Which of the following works best to compute this?

a) P(XN < 200; Mu = 180, Sigma = 180)

b) P(XB > 200; p=0.6, n=300)

c) P(XB > 200.5; p=0.6, n=300)

d) P(Tw > 10; a and b to be computed from data

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
