The expression is \boxed{6{x^9}} which is equivalent to \sqrt[3]{{216{x^{27}}}} a perfect cube.Option (b) is correct.

Further Explanation:

Given:

The expression is \sqrt[3]{{216{x^{27}}}}.

The options are as follows,

(a). 6{x^3}

(b). 6{x^9}

(c). 72{x^3}

(d). 72{x^9}

Calculation:

The given expression is \sqrt[3]{{216{x^{27}}}}.

Consider the given expression as A = \sqrt[3]{{216{x^{27}}}}.

Solve the above expression to obtain the simplest form.

\begin{aligned}A&= \sqrt[3]{{216{x^{27}}}}\\&= \sqrt[3]{{{{\left( 6 \right)}^3}{{\left( {{x^9}} \right)}^3}}}\\&=\sqrt[3]{{{{\left( {6{x^9}} \right)}^3}}}\\&= 6{x^9}\\\end{aligned}

The simplest form of the expression is 6{x^9}.

The expression is \boxed{6{x^9}} which is equivalent to \sqrt[3]{{216{x^{27}}}} a perfect cube.Option (b) is correct.

Option (a) is not correct as the \sqrt[3]{{216{x^{27}}}} is 6{x^9}.

Option (b) is correct as the \sqrt[3]{{216{x^{27}}}} is 6{x^9}.

Option (c) is not correct as the \sqrt[3]{{216{x^{27}}}} is 6{x^9}.

Option (d) is not correct as the \sqrt[3]{{216{x^{27}}}} is 6{x^9}.

Which angle in triangle DEF has the largest measure?​
nordsb [41]

Answer:

D is the largest angle

Step-by-step explanation:

The angle opposite the largest side is the largest and the angle opposite the smallest side is the smallest.

Since 12 is the largest side, angle D is the largest

8 is the smallest side, F is the smallest angle

Solve the problem. Use the Central Limit Theorem.The annual precipitation amounts in a certain mountain range are normally distr
bazaltina [42]

Answer:

0.8944 = 89.44% probability that the mean annual precipitation during 25 randomly picked years will be less than 112 inches.

Step-by-step explanation:

To solve this question, we use the normal probability distribution and the central limit theorem.

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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes 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.

Mean of 109.0 inches, and a standard deviation of 12 inches.

This means that \mu = 109, \sigma = 12

Sample of 25.

This means that n = 25, s = \frac{12}{\sqrt{25}} = 2.4

What is the probability that the mean annual precipitation during 25 randomly picked years will be less than 112 inches?

This is the p-value of Z when X = 112. So

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

By the Central Limit Theorem

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

Z = \frac{112 - 109}{2.4}

Z = 1.25

Z = 1.25 has a p-value of 0.8944.

0.8944 = 89.44% probability that the mean annual precipitation during 25 randomly picked years will be less than 112 inches.
