(a)  P= \frac{A}{e^{rt}} 

(b) e^{rt}= \frac{A}{P} 

ln e^{rt}= ln(\frac{A}{P}),  
rt=  ln(\frac{A}{P}),   t= \frac{ ln(\frac{A}{P})}{r}, or,   t= \frac{ lnA - lnP}{r},

A man wins in a gambling game if he gets two heads in five flips of a biased coin. the probability of getting a head with the co
Semenov [28]

The probability the man will win will be 13.23%. And the probability of winning if he wins by getting at least four heads in five flips will be 36.01%.

<h3>How to find that a given condition can be modeled by binomial distribution?</h3>

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

P(X = x) = ⁿCₓ pˣ (1 - p)⁽ⁿ⁻ˣ⁾

A man wins in a gambling game if he gets two heads in five flips of a biased coin. the probability of getting a head with the coin is 0.7.

Then we have

p = 0.7

n = 5

Then the probability the man will win will be

P(X = 2) = ⁵C₂ (0.7)² (1 - 0.7)⁽⁵⁻²⁾

P(X = 2) = 10 x 0.49 x 0.027

P(X = 2) = 0.1323

P(X = 2) = 13.23%

Then the probability of winning if he wins by getting at least four heads in five flips will be

P(X = 4) = ⁵C₄ (0.7)⁴ (1 - 0.7)⁽⁵⁻⁴⁾

P(X = 4) = 5 x 0.2401 x 0.3

P(X = 4) = 0.3601

P(X = 4) = 36.01%

Write the x-intercept of the graph of -6x + y = 8.
Trava [24]

Answer:

x-intercept:  x = -4/3

Step-by-step explanation:

x-intercept when y = 0

-6x + 0 = 8

so

-6x = 8

x = 8/-6

x = -4/3
