The missing options are given below.

A. S/3 + 10

B. S/2 + 10

C. S + 10

D. - S/3 + 10

to convert 25min into hours we divide 25 by 60 so the answer would be 0.416 hours

the formula to find the distance is we multiply speed and time so

distance=4km/p X 0.416 hours =1.664

so now we have the first answer

now we do the same thing for the other part of the question

distance= timeXspeed

distance=0.416X3=1.248

then we add to find total distance

1.248+1.644=2.912

2.912 is the total distance

Answer:  6x+4x +13x+6 equal

The value of angle S is 53°

Exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of two remote interior angles.

With this theorem we can say that

7x+2 = 4x+13+19

collecting like terms

7x -4x = 13+19-2

3x = 30

divide both sides by 3

x = 30/3

x = 10

Since x = 10

angle S = 4x+13

angle S = 4(10) +13

= 40+13

= 53°

Therefore the measure of angle S is 53°

Given the quadratic inequality;

x² + 2x - 8 ≥ 0

We have to determine the value(s) for x

Using factorization, we have to determine the pair factors of -8 that sums up to 2, they are 4 and -2

Substitute the values into the expression

x² + 4x - 2x - 8

Factor out the common terms

x(x + 4) - 2( x + 4)

We then have;

(x + 4) ( x -2) ≥ 0

The values for x are;

x + 4 ≥ 0

x ≥ -4

And

x - 2 ≥ 0

x ≥ 2

Thus, the values of x in the quadratic inequality are x ≥ -4 and x ≥ 2

The type of sampling that relies upon knowledge of the distribution or proportion of population characteristics in order to choose a sample that assures representativeness of these characteristics is called stratified sampling.

In stratified sampling, the population is divided into different subgroups or strata based on specific characteristics or variables. The proportion of each subgroup in the population is known, and a sample is then selected from each stratum. This ensures that the sample is representative of the population in terms of the specific characteristics being studied.

To perform stratified sampling, follow these steps:
1. Identify the relevant characteristics or variables that you want to study.
2. Divide the population into distinct strata based on these characteristics.
3. Determine the proportion or distribution of each stratum in the population.
4. Select a random sample from each stratum, ensuring that the sample size is proportional to the size of the stratum in the population.
5. Combine the samples from each stratum to create the overall representative sample.

In conclusion, stratified sampling is a type of sampling method that ensures representativeness of population characteristics by dividing the population into subgroups and selecting samples from each stratum based on their proportion in the population.

The crank angle value when the piston is at Top Dead Center (TDC) is 0 radians or 0 degrees. The maximum ratio of the crank radius to the connected length is 0.3.

The crank angle value refers to the angle between the crankshaft and a reference point when measuring the position of the piston. When the piston is at Top Dead Center (TDC), it is at its highest point in the cylinder. The crankshaft is positioned such that the connecting rod is aligned with the crank radius and the piston is at the topmost position. This corresponds to a crank angle value of 0 radians or 0 degrees.

Regarding the maximum ratio of the crank radius to the connected length, this value is given as 0.3. The crank radius is the distance from the center of the crankshaft to the center of the crank pin, and the connected length is the distance from the center of the crank pin to the center of the piston pin. The maximum ratio of 0.3 indicates that the crank radius is 0.3 times the connected length.

It's important to note that these values are specific to the context of the problem statement provided. Different engines or mechanisms may have different values for the crank angle at TDC and the maximum ratio of crank radius to connected length.

If the assumption for using the chi-square statistic, which specifies the number of frequencies in each category, is violated, the researcher has a few options to address this issue:

1. Combine categories: If some categories have very low expected frequencies, they can be combined with adjacent categories to increase the expected frequencies. This helps to meet the assumption of having a minimum expected frequency in each category.

2. Recategorize data: The researcher can also recategorize the data by collapsing categories or creating new categories that have more balanced frequencies. This can help to ensure an adequate number of observations in each category.

3. Use alternative statistical tests: If the assumptions for using the chi-square statistic cannot be met, the researcher can consider using alternative statistical tests. For example, if the data have a small sample size or violate the assumption of expected frequencies, Fisher's exact test or Monte Carlo simulation can be used as alternatives.

It is important for the researcher to carefully consider the specific circumstances and consult with a statistician to determine the most appropriate approach when the assumptions for using the chi-square statistic are violated.

The equation of the parabola that models the situation is given by:

(x - 1)² = -16(y - 5).

The equation of a quadratic function, of vertex (h,k), is given by:

(x - h)² = 4p(y - k).

The focus is located at point (h, k + p).

For this problem, to find the values of the parameters h and k, we have that:

Hence:

h = 1, k = 5.

And:

(x - 1)² = 4p(y - 5).

For the focus, and subsequently to find parameter p, we have that:

Hence:

k + p = 1.

5 + p = 1

p = -4.

Then the equation of the parabola that models this situation is given by:

(x - 1)² = 4p(y - 5).

(x - 1)² = 4(-4)(y - 5).

(x - 1)² = -16(y - 5).

The function f represents the cost of renting the tractor, is f(x) = 40x + 100 and the function g represents the cost if the hourly rate were doubled is g(x) = 80x + 100

The slope of the graph g is double of the graph f, and difference of y intercept of both the graph is multiple of 40.

A function is defined as a relation between a set of inputs having one output each.

Given that, The cost of renting a landscaping tractor is a $100 security deposit plus the hourly rate is $40/hour

According to question,

Function f representing total cost for x hours is f(x) = 40x + 100

Function g representing total cost for x hours is g(x) = 80x + 100

Comparing with y = mx + c we get

Slope for f(x) = 40

Slope for g(x) = 80

Hence, The slope of the graph g is double of the graph f, and difference of y intercept of both the graph is multiple of 40, also The function f represents the cost of renting the tractor, is f(x) = 40x + 100 and the function g represents the cost if the hourly rate were doubled is g(x) = 80x + 100
