Option B is the correct answer.

An observational study is a research method in which the researcher observes and records behavior or data without directly manipulating the variables.

We have,

In an observational study, the researcher simply observes and records data as it naturally occurs, without interfering or influencing the study participants.

This type of study is often used in social science research, as well as in medical research and epidemiology, to study the relationships between variables and to identify patterns or trends in the data.

Observational studies can be either cross-sectional, where data is collected at a single point in time, or longitudinal, where data is collected over an extended period of time.

In this case,

The researchers are simply observing and collecting data without actively manipulating any variables or performing any interventions.

Thus,

The algebraic equation "0.40x = 400" represents the words: forty percent of Mrs. Garcia's score is 400 points. Mrs. Garcia's score is 1000.

Algebraic equation is an equation made up of variables and coefficients that can be used to solve mathematical problems or questions.

To formulate an algebraic equation, we designate a variable for unknown values.

Mrs. Garcia's score is unknown, and so

let x = Mrs. Garcia's score

Based on the information given on the problem, forty percent of Mrs. Garcia's score is 400 points. Forty percent can be written as 0.40.

40% of x is 400

0.40x = 400

Hence, the algebraic equation for that is 0.40x = 400.

Evaluating the value of x,

0.40x = 400

x = 400 / 0.40

x = 1000

Therefore, Mrs. Garcia's score is 1000.

Answer:

2.40G + 1.20C ≤15

Step-by-step explanation:

The inequality function is

Given that

The cost of goat milk for each liter is $2.40 = G

And, the cost of the cow milk for each liter is $1.20 = C

Now the equation would be

2.40g + 1.20c

Now this must be lower or equal than $15

So, the inequality function would be

2.40G + 1.20C ≤15

hence, the inequality function is 2.40G + 1.20C ≤15

Answer:

2.4G + 1.2C < or = to 15

Answer:

IJ is 5.8 ft

Step-by-step explanation:

Here, we want to calculate the length of IJ

to Find IJ, we need the appropriate trigonometric ratio

The trigonometric ratio to use in this case is the one that connects the opposite and the adjacent

from the question, IJ is the opposite

This is the side facing the given angle

HI is the hypotenuse which is the side facing the right-angle

HJ is the third side which is the adjacent

Mathematically;

That is the Tan

Tan 71 = IJ/2

IJ = 2 Tan 71

IJ = 5.8

There were substantial differences in alcohol and drug usage by the manner of administration, however, problem drinking and drug use were present in 21.1% and 2.8% of the group, respectively.

The topic of whether data from population surveys could be gathered more quickly and affordably than using paper questionnaires is brought up by the widespread accessibility of computer-based technologies like the Internet and Interactive Voice Response (IVR) systems. The issue extends to whether it is possible to assess the prevalence of such behaviors in the general population when dealing with potentially stigmatized behaviors like problematic alcohol and drug use without endangering the accuracy of the findings. This study evaluates the reliability, response rate, and problematic alcohol and drug use of the Internet and IVR versions of the AUDIT and DUDIT. Randomly chosen from the Swedish general population, 5000 people were contacted by mail and asked to respond to the AUDIT and DUDIT questionnaires online or over the phone.

The minutes it will take for the tank to be 3/5 full is 720 minutes.

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below. An example of a fraction is 3/5.

The first step is to determine how many gallons the tank would have when it is 3/5 full. To determine this value, multiply the volume of the tank by 3/5.

Gallons when the tank is 3/5 full = 3/5 x  48,000 = 28,800

Now, divide the speed of the water by the gallons in the tank when it is 3/5 full.

The angles 6 and 16 are same side exterior angles

=================================================

Explanation:

Erase everything but lines p, q, and s. Also, we'll keep angles 6 and 16 as well. Check out the diagram below.

As you can see from the diagram, lines p and q act like the parallel lines. Imagine we can shift line p to make it horizontal so it's parallel to line q. This might help show that angles 6 and 16 are same side exterior angles.

Note: Because line p is not parallel to line q, this means angles 6 and 16 are not supplementary (they don't add to 180).

Answer:

If Cora runs 1/2 mile per week and x is the number of weeks, then she will run 5+1/2x. Then determine how many weeks are in two and a half months (depends on which month it is as there are less weeks in February than in January!) but we could estimate 6.

For Hana, you will have 3+ 3/4 x

Step-by-step explanation:

First equation is y=5+1/2 x and then plug 6 in for x to solve for y. the second equation is y=3+3/4x and plug in 6.

The system of equations to describe this scenario are

The variable x means the number of weeks they ran and the y variable means the total distance they covered in miles .

The situation can be modelled like a linear equation.

Therefore,

y = mx + b

where

m = slope

b = y-intercept

Cora race will be as follows:

Hana race will be as follows:

The variable x which is the independent variable is the number of weeks each of them ran in the equation.

The variable y which is the dependent variable is the total distance covered in miles.

The smallest value of the other number will be 3 ×5× 11 =165

In the given statement is :

When the least common multiple of two positive integers is divided by their greatest common divisor, the result is 33. If one integer is 45.

To find what is the smallest possible value of the other integer

Now, According to the question

One of the numbers 3 ×3× 5 = 45

The lowest common multiple has to be a multiple of 45 i.e.,

3 ×3× 5 something when LCM is divided by the greatest common divisor

then the answer is 33 = 3 x 11 .

So the other number will have to be a multiple of 11

3 ×3× 5× 11 × ?/ some factor of 4 = 33

(3 ×5) ×3× 11 × 1 /3 × 5 = 33

So if the greatest common divisor is 3× 5 the given number is 3 ×3× 5
