20 kg bag of bananas for $10

Andrew [12]

20 kg bag of bananas for 10 dollars This is the given situation in which in every 20 kilogram of bananas, the costs is 10 dollars. Now, let us calculate how much each kg of banana costs will. Let’s solve for the unit rate of this given data: => 20 kg bag of banana => 10 dollars = cost Now, let’s divide this to get the answer that we need. => 20 / 10 => 2 bananas per dollars = 2 banana/dollars Or 10 / 20 => 0.5 dollars/1kg of banana

Answer:

4.46% probability that the pressure will exceed this value.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Gaussian distribution with a mean value of 69 psi and a standard deviation of 10 psi.

Gaussian distribution = normal.

This means that $\mu = 69, \sigma = 10$

If it is important that the pressure stays below 86 psi, what is the probability (in percent) that the pressure will exceed this value?

As a proportion, this probability is 1 subtracted by the pvalue of Z when X = 86. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{86 - 69}{10}$

$Z = 1.7$

$Z = 1.7$ has a pvalue of 0.9554

1 - 0.9554 = 0.0446

0.0446*100 = 4.46%

4.46% probability that the pressure will exceed this value.
