Can y’all tell me what all numbers are rational or irrational
murzikaleks [220]

The irrational numbers among these given are:

\sqrt{83}, 24\pi, 90.790170..., \sqrt{109}

The remaining numbers are all rational.

<h3>What are rational and irrational numbers?</h3>

  • Rational numbers are numbers that can be represented by fractions, such as terminating decimals.
  • Irrational numbers are numbers that cannot be represented by fractions, such as non-terminating decimals and non-exact roots.

The irrational numbers in this problem are:

  • Square root of 83, as it is a non-exact root.
  • 24π, as π is a non-terminating decimal.
  • 90.790170, which is a non-terminating decimal.
  • Square root of 109, as it is a non-exact root.

The amount of potato chips an 18-ounce bag contains follows a normal distribution with a mean of 18.5 ounces and a standard devi
bekas [8.4K]

Answer:

100% probability that the sample mean weight of these 100 bags is less than 18.6 ounces

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are 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.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question, we have that:

\mu = 18.5, \sigma = 0.2, n = 100, s = \frac{0.2}{\sqrt{100}} = 0.02

What is the probability that the sample mean weight of these 100 bags is less than 18.6 ounces

This is the pvalue of Z when X = 18.6. So

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

By the Central Limit Theorem

Z = \frac{X - \mu}{s}

Z = \frac{18.6 - 18.5}{0.02}

Z = 5 has a pvalue of 1

100% probability that the sample mean weight of these 100 bags is less than 18.6 ounces

Two word problems :)
Likurg_2 [28]
7 out of 50 people so to find the whole amount u must multiply 50x8 to =400 and multiply 7x8 =56 therefore 56 out of 400 have traveled to a foreign country. however 56 is not MORE THAN 56. if it said 56 or more he would be correct but because he says more than 56 he is incorrect. hope that helps!
