Answer:
x Superscript 9 Baseline (RootIndex 3 StartRoot y EndRoot)
OR x^9/(∛y)
Step-by-step explanation:
Given the indicinal equation
(x^27/y)^1/3
To find the corresponding expression, we will simplify the equation as shown:
(x^27/y)^⅓
= (x^27)^⅓/y⅓
= {x^(3×9)}^⅓/y⅓
= x^9/y⅓
= x^9/(∛y)
The right answer is x Superscript 9 Baseline (RootIndex 3 StartRoot y EndRoot)
Answer:
Option C is correct.
Environmental regulation has led to dramatic improvements in air and water quality.
Step-by-step explanation:
- The national forests are protected from the exploitive ""dual use policy.
The dual use policy on any idea, technology, breakthrough etc. means such concept can be used for its intended purpose and for military use.
Natural forests are not excluded from this dual use policy & plenty forest exploiters hide under this policy to literally exploit natural forests.
- The Environmental Protection Agency was elevated to cabinet status in 1998 by President Clinton and the Republican Congress
This is not true as the EPA is still not a Cabinet department, but the Administrator is normally given cabinet rank.
- Environmental regulation has led to dramatic improvements in air and water quality.
Regulations have led plenty industries at the forefront of pollution to sit up and fix up. Strict laws and hefty fines have discouraged various water and air pollution means since those regulations came into place. This is the only correct statement about environmental policy amongst the options.
- Policymakers always give more consideration to environmental protection than to economic development when the two conflict.
This is true sometimes, but 'always'!? No, policymakers do not always give more consideration to environmental protection than to economic development when the two conflict.
Using the normal distribution, we have that:
- The distribution of X is
.
- The distribution of
is
.
- 0.0597 = 5.97% probability that a single movie production cost is between 55 and 58 million dollars.
- 0.2233 = 22.33% probability that the average production cost of 17 movies is between 55 and 58 million dollars. Since the sample size is less than 30, assumption of normality is necessary.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
In this problem, the parameters are given as follows:

Hence:
- The distribution of X is
.
- The distribution of
is
.
The probabilities are the <u>p-value of Z when X = 58 subtracted by the p-value of Z when X = 55</u>, hence, for a single movie:
X = 58:


Z = 0.05.
Z = 0.05 has a p-value of 0.5199.
X = 55:


Z = -0.1.
Z = -0.1 has a p-value of 0.4602.
0.5199 - 0.4602 = 0.0597 = 5.97% probability that a single movie production cost is between 55 and 58 million dollars.
For the sample of 17 movies, we have that:
X = 58:


Z = 0.19.
Z = 0.19 has a p-value of 0.5753.
X = 55:


Z = -0.38.
Z = -0.38 has a p-value of 0.3520.
0.5753 - 0.3520 = 0.2233 = 22.33% probability that the average production cost of 17 movies is between 55 and 58 million dollars. Since the sample size is less than 30, assumption of normality is necessary.
