Answer:

a) \(2^{4}\)

b) \(5^{3}\) x \(7^{2}\)

Step-by-step explanation:

You can group together like base values, so 3 x 3 x 3 x 3 x 3 becomes 3 to the power of 5. All it means is that you are multiplying the base value (in this case 3) by itself 5 times.

Index notation makes it easier in more complex equations to solve, as its simpler and doesn't take up as much space.

The one-sample chi-square test is used to determine whether the distribution of a single categorical variable significantly differs from what would be expected by chance. The statement is True.

The one-sample chi-square test is a statistical test used to determine if there is a significant difference between the observed frequency and the expected frequency in a single categorical variable. It compares the observed frequency distribution of a variable to the expected frequency distribution, assuming that the null hypothesis is true.

This test compares observed frequencies to expected frequencies and calculates a chi-square statistic to assess the significance of the difference.

Answer:

16 cans per minute

Step-by-step explanation:

Its simple 80 divided by 5 is 16 so ever minute 16 cans are packed.

The ratio of the cans to minutes is 80 : 5 or 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.

A machine can pack 80 cans in 5 minutes.

let's denote the number of cans with X and

Time with T

So we have to find the value of X : T

X = 80 and

T = 5 minutes

X : T = 80 : 5  or

X : T = 16 : 1   (divide by 5 on both sides)

It means the machine can pack 16 cans per minute.

Thus, the ratio of the cans to minutes is 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

Step-by-step explanation:

The Anwser is B

The function \[ g(x)=2 \sqrt{3 e^{-6 x}+2} \] is decreasing on all intervals.

To determine the intervals on which the given function is increasing or decreasing, we need to find the derivative of the function \( g(x) = 2 \sqrt{3 e^{-6 x}+2} \), denoted as \( g'(x) \).

To find the derivative, we can use the chain rule. The derivative of \( \sqrt{u} \) is \( \frac{1}{2\sqrt{u}} \cdot \frac{du}{dx} \). Let's apply the chain rule to find \( g'(x) \):

\[ g'(x) = \frac{d}{dx}\left[2 \sqrt{3 e^{-6 x}+2}\right] \]

Applying the chain rule, we get:

\[ g'(x) = 2 \cdot \frac{1}{2\sqrt{3 e^{-6 x}+2}} \cdot \frac{d}{dx}\left[3 e^{-6 x}+2\right] \]

\[ g'(x) = \frac{1}{\sqrt{3 e^{-6 x}+2}} \cdot \frac{d}{dx}\left[3 e^{-6 x}+2\right] \]

Now, let's find the derivative of \(3 e^{-6 x}+2\) with respect to \(x\):

\[ \frac{d}{dx}\left[3 e^{-6 x}+2\right] = 3 \cdot \frac{d}{dx}\left[e^{-6 x}\right] + \frac{d}{dx}\left[2\right] \]

Since \(e^{-6 x}\) is an exponential function, its derivative is \(e^{-6 x} \cdot (-6)\):

\[ \frac{d}{dx}\left[e^{-6 x}\right] = e^{-6 x} \cdot (-6) \]

The derivative of a constant term like \(2\) is \(0\):

\[ \frac{d}{dx}\left[2\right] = 0 \]

Substituting these values back into the equation for \(g'(x)\):

\[ g'(x) = \frac{1}{\sqrt{3 e^{-6 x}+2}} \cdot \left(e^{-6 x} \cdot (-6) + 0\right) \]

Simplifying:

\[ g'(x) = \frac{-6 e^{-6 x}}{\sqrt{3 e^{-6 x}+2}} \]

Now that we have the derivative, we can determine the intervals on which the given function \(g(x)\) is increasing or decreasing.

For the given function \(g(x) = 2 \sqrt{3 e^{-6 x}+2}\), the derivative \(g'(x) = \frac{-6 e^{-6 x}}{\sqrt{3 e^{-6 x}+2}}\).

To determine the intervals of increase and decrease, we need to find where \(g'(x)\) is positive or negative.

When \(g'(x) > 0\), the function is increasing.

When \(g'(x) < 0\), the function is decreasing.

Since the denominator \(\sqrt{3 e^{-6 x}+2}\) is always positive, the sign of \(g'(x)\) will be determined by the numerator \(-6 e^{-6 x}\).

Setting \(g'(x) > 0\) and solving for \(x\):

\[ -6 e^{-6 x} > 0 \]

Dividing both sides by \(-6\), we get:

\[ e^{-6 x} < 0 \]

Since \(e^{-6 x}\) is always positive, there are no values of \(x\) that satisfy \(e^{-6 x} < 0\).

Therefore, \(g'(x)\) is never positive and the function \(g(x)\) is never increasing.

Setting \(g'(x) < 0\) and solving for \(x\):

\[ -6 e^{-6 x} < 0 \]

Dividing both sides by \(-6\), we get:

\[ e^{-6 x} > 0 \]

Since \(e^{-6 x}\) is always positive, all values of \(x\) satisfy \(e^{-6 x} > 0\).

Therefore, \(g'(x)\) is always negative and the function \(g(x)\) is always decreasing.

Therefore, the given function \(g(x) = 2 \sqrt{3 e^{-6 x}+2}\) is decreasing on all intervals.

Hence, the function is decreasing on all intervals.

The Paired samples t-test is the most suitable statistical technique for comparing the mean span of the dominant and non-dominant hands in this study.

To investigate whether the span of a person's dominant hand is greater than that of their non-dominant hand, the most appropriate statistical technique would be the Paired samples t-test.

The Paired samples t-test is used when comparing the means of two related groups or conditions. In this case, the dominant and non-dominant hands are related because they belong to the same individuals in the study. By comparing the means of the dominant and non-dominant hand spans, we can determine if there is a significant difference between the two.

The other options listed, ANOVA (Analysis of Variance), Independent samples t-test, Wilcoxon's matched-pairs signed rank test, and Mann-Whitney U test, are not suitable for this scenario because they are designed for different types of comparisons:

- ANOVA is used when comparing the means of three or more independent groups, which is not the case here.

- Independent samples t-test is used when comparing the means of two independent groups, which is not the case here as the measurements are paired.

- Wilcoxon's matched-pairs signed rank test and Mann-Whitney U test are non-parametric tests that are used when the data do not meet the assumptions of parametric tests. However, in this case, we have paired measurements, and the paired samples t-test is the appropriate parametric test.

Therefore, the Paired samples t-test is the most suitable statistical technique for comparing the mean span of the dominant and non-dominant hands in this study.

The statement describes a set of interest in a study, which is the set of all elements being investigated or under consideration. It is not a sample, which refers to a subset of the population being studied.

The set of all elements of interest in a study is called the population. It refers to the entire group of individuals, objects, or measurements that are being studied and from which data can be collected. The population can be finite or infinite and can include people, animals, plants, materials, or any other object or concept of interest. In statistical analysis, researchers use samples of the population to make inferences or draw conclusions about the entire population. By selecting a representative sample, researchers can reduce the cost and time required for data collection and analysis while still obtaining valid and reliable results.

C (4, 5 )

5 ≥ 4 - 5

5 ≥ - 1 ← true

3(5) < - 6(4) + 3

15 < - 24 + 3

15 < - 21 ← false

The functions \(g(x) = x^{1/3} - 5\) and h(x) = -2x + 4 satisfy the condition f(x) = g(h(x)), and neither g(x) nor h(x) is solely x.

To find functions g(x) and h(x) such that f(x) = g(h(x)), where neither g(x) nor h(x) is solely x, let's start with the given function:

f(x) = ∛(-2x + 4) - 5

We can rewrite f(x) as:

f(x) = g(h(x))

To find h(x), we want to identify the inner function that transforms x into -2x + 4. So, let's set h(x) = -2x + 4.

Now, we need to find g(x) such that g(h(x)) = f(x). We want to express f(x) in terms of g(x).

Since h(x) = -2x + 4, we have:

g(h(x)) = g(-2x + 4)

We need to find a function g(x) that when applied to -2x + 4 will give us ∛(-2x + 4) - 5. To do this, we can set g(x) = \(x^{1/3}\) - 5.

Now we have:

\(g(h(x)) = (-2x + 4)^{1/3} - 5\)

Therefore, the functions \(g(x) = x^{1/3} - 5\) and h(x) = -2x + 4 satisfy the condition f(x) = g(h(x)), and neither g(x) nor h(x) is solely x.

The complete question is:

Given f(x) find g(x) and h(x) such that f(x) = g(h(x)) and neither g(x) nor h(x) is solely x \(f(x) = \sqrt[3]{- 2x + 4} -5\)

The surface area of the square pyramid is 115 square meters

From the question, we have the following parameters that can be used in our computation:

The square based pyramid

The formula for the surface area of a square pyramid is:

S = a² + 2al

where a is the length of one side of the square base and l is the slant height.

Area of 4 triangles

This is calculated as

A = 1/2 * 5 * 9 * 4 = 90

Area of the square

This is calculated as

A = 5 * 5 = 25

So, we have

Area = 90 + 25

Area = 115
