The option that is the better deal between both deals for apples, is 8 apples for $9.25.

The better deal on the apples would be the deal that gives the lower amount per apple. This means that the deal that leads to each individual apple having a lower price is the deal that should be considered best.

To find the price of an apple, you would need to divide the price of the deal given, by the number of apples in the deal.

The first deal would therefore have a per apple price of :

= Price of deal / Number of apples

= 6. 25 / 5 apples

= $ 1. 25 per apple

The second deal would be :

= Price of deal / Number of apples

= 9. 25 / 8 apples

= $ 1. 16 per apple

The better deal is therefore 8 apples for $9.25.

Statistical hypothesis testing employs the null and alternate hypotheses.

The alternative hypothesis of a test expresses the prediction of an effect or relationship based on your study, while the null hypothesis of the test does not yet predict an effect or an association between the variables.

A statement that there is no relationship between two variables is called a null hypothesis. Another hypothesis is that the two variables are statistically correlated.

Alternative unilateral (directional) or the bilateral (non-directional) hypotheses are also possible. Simple, complex, true, and false are the four main categories of null hypotheses. If the p-value is greater than the statistical significance level, null hypothesis is preferred.

The graph of the function g(x) = 3/4 f(x) on the same coordinate plane as f(x) = x is attached below.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

To graph the function g(x) = 3/4 f(x) on the same coordinate plane as f(x) = x, we need to perform the transformation of stretching the graph of f(x) by a factor of 3/4.

Determine the scale factor for the transformation. In this case, the scale factor is 3/4.

Starting at the x-intercepts and y-intercepts (if there are any), plot the points on the coordinate plane using the scale factor to stretch or shrink the graph as needed.

For example, the point (0,0) on the graph of f(x) becomes the point (0,0) on the graph of g(x). The point (1,1) on the graph of f(x) becomes the point (1, 3/4) on the graph of g(x).

Connect the plotted points with a smooth curve to obtain the graph of g(x).

In an arithmetic sequence the difference between the consecutive terms is always constant. Using arithmetic sequence, it is easier to predict a term in the given sequence or progression. Following is the equation used:

\(A_{n}\)= A₁ + (n-1) d

Where,

\(A_{n}\) = nth term of the sequence

A₁ = first term of the sequence

n =  terms given in the sequence

d = common difference between progressive terms

Now, in the given question,

\(A_{n}\) = the distance travelled by car in 1 hour

A₁ = 300m (initial distance)

n = 60 minutes

d = 120m (difference between the progressive distance at each minute)

Since, \(A_{n}\) = A₁ + (n-1) d

\(A_{n}\) = 300+(59)*120

For fixed population standard deviation and level of significance, the minimum sample size needed to guarantee a given margin of error decreases as the margin of error increases.

The square root of the variance for the given set of numbers is what the standard deviation examines. It is employed to compute a confidence interval for making judgments (such as accepting or rejecting a hypothesis).

Here, the population standard deviation, and level of significance are the same.

As the margin of error increased.

So, with the increase in the value of the margin of error, there will surely decrease in the value of the sample size

The critical value that is used to construct a confidence interval for a proportion depends upon C. the confidence level and the sample size.

The critical value used to construct the confidence interval for proportion depends on:

1) The sample size:

The probability changes as the sample size changes as the distribution of the test statistics is dependent on sample size, thus the critical value will depend on sample size.

2) The confidence level:

The critical value is always calculated by using the confidence level, so it is dependent on it.

The sample proportion is the observed value which is used to perform the test, but not to construct the critical value.

The function f(x) = x⁴ - 8x² + 6 is increasing on the intervals (-2, 0) and

(2, ∞), decreasing on the intervals (-∞, -2) and (0, 2), has a local minimum at x = -2 with a value of -10, a local maximum at x = 0 with a value of 6, and has inflection points at x = -2 and x = 2.

To find the intervals of increasing and decreasing for the function

f(x) = x⁴ - 8x² + 6, we first take the derivative. The derivative is

f'(x) = 4x³ - 16x. We then find the critical points by setting f'(x) equal to zero:

4x³ - 16x = 0. Factoring out 4x, we get

4x(x² - 4) = 0, which gives us

x = 0,

x = -2, and

x = 2 as critical points.

Next, we test the intervals between the critical points and endpoints by choosing test values and evaluating the sign of the derivative. We find that f is increasing on the intervals (-2, 0) and (2, ∞), and decreasing on the intervals (-∞, -2) and (0, 2).

To find the local maximum and minimum values, we evaluate the function at the critical points and find that

f(-2) = -10 and

f(0) = 6, indicating a local minimum and maximum, respectively.

For inflection points, we look at the concavity of the function. Taking the second derivative,

f''(x) = 12x² - 16. Setting f''(x) equal to zero, we find x² = 4, which gives us

x = -2 and x = 2. By analyzing the concavity on the intervals, we determine that the function changes concavity at x = -2 and

x = 2.

Therefore, the function

f(x) = x⁴ - 8x² + 6 is increasing on the intervals (-2, 0) and (2, ∞), decreasing on the intervals (-∞, -2) and (0, 2), has a local minimum at

x = -2 with a value of -10, a local maximum at x = 0 with a value of 6, and inflection points at x = -2 and

x = 2.

Now multiply by the height to find volume

10140 km^2  * 15 km  = 152100 km^3

To differentiate the function f(x) = x^5), we can use the power rule of differentiation. According to the power rule, if we have a function of the form f(x) = x^n), where (n) is a constant, then its derivative is given by:

[f(x) = nx^{n-1}]

Applying this rule to f(x) = x^5), we have:

[f(x) = 5x^{5-1} = 5x^4]

Therefore, the derivative of f(x) = x^5) is (f(x) = 5x^4).
