5 times as many. Since dog B has 2 and dog A has 10, A = 2 * X, since you’re solving for the multiplication comparison. 10/2 = 5, so you’ve got 5 times as many.

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.

There are 25 boxes of paper. each box has 789 pieces of paper. how many pieces of paper are in all?

nika2105 [10]

This is a pretty basic multiplication problem.

If one box has 789 pieces of paper in it and there are 25 boxes, you will simply multiply 789 x 25

789 x 25 = 19,725.

This shows that there are 19,725 pieces of paper in the 25 boxes of paper.

A mountain bike costs $675. If the sales tax is 8%, find the total cost of the bike. Round to the nearest cent, if

lisov135 [29]

Answer:

$729.00

Step-by-step explanation:

The tax is ...

0.08 × $675 = $54.00

So, the total cost of the bike is ...

$675 +54 = $729.00
