The answer is B because the hours would be the bottom intervals of 1 and the distance traveled (in miles) is the constant of 5.25. So, overall in one hour, you would’ve traveled 5.25 miles. (It’s like driving a car... you’d be going at a speed of 5.25 mph (which is kinda slow).

Consider the following binomial experiment. A company owns 4 machines. The probability that on a given day any one machine will

const2013 [10]

Answer:

There is a 73.11% probability that at least 2 machines will break down on a given day.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem we have that:

There are 4 machines, so $n = 4$ .

The probability that on a given day any one machine will break down is 0.53. This means that $p = 0.53$ .

What is the probability that at least 2 machines will break down on a given day?

$P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{4,2}.(0.53)^{2}.(0.47)^{2} = 0.3723$

$P(X = 3) = C_{4,3}.(0.53)^{3}.(0.47)^{1} = 0.2799$

$P(X = 4) = C_{4,4}.(0.53)^{4}.(0.47)^{0} = 0.0789$

$P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.3723 + 0.2799 + 0.0789 = 0.7311$

There is a 73.11% probability that at least 2 machines will break down on a given day.

PLEASE REMEMBER PUT THEM IN THE CORRECT ORDER

antiseptic1488 [7]

1.) set up the problem as if there were no decimals

4.) Multiply

2.) count the numbers behind the decimals in the problem

3.) count over that number of spaces from the right in your to place the decimal
