Which sentence correctly compares the number of 1 4 4 1 -pound and 1 2 2 1 -pound packages that the deli can slice from a 12

frutty [35]

The statements aren't given; however the number of 1/2 and 1/4 - pound package have been calculated below.

Answer:

Step-by-step explanation:

Given :

A 12 pound block :

Number of 1/2 pound packages that can be obtained :

12 ÷ 1/2 ;

12 * 2/1 = 24 (1/2 - Pound package) can be obtained.

Number of 1/4 pound package that can be obtained :

12 ÷ 1/4

12 * 4 /1 = 48 (1/4 - Pound package) can be obtained

We can obtain twice the number of 1/2 - pound package by using the 1/4 - pound slicing.

A boiler has five identical relief valves. The probability that any particular valve will open on demand is 0.93. Assume indepen

noname [10]

Answer:

There is a 99.99998% probability that at least one valve opens.

Step-by-step explanation:

For each valve there are only two possible outcomes. Either it opens on demand, or it does not. This means that we use the binomial probability distribution to solve this problem.

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:

$n = 5, p = 0.93$

Calculate P(at least one valve opens).

This is $P(X \geq 1)$

Either no valves open, or at least one does. The sum of the probabilities of these events is decimal 1. So:

$P(X = 0) + P(X \geq 1) = 1$

$P(X \geq 1) = 1 - P(X = 0)$

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

$P(X = 0) = C_{5,0}.(0.93)^{0}.(0.07)^{5} = 0.0000016807$

Finally

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0000016807 = 0.9999983193$

There is a 99.99998% probability that at least one valve opens.
