A researcher conducts an experiment to determine whether moderate doses of St. John's Wort have any effect of memory for college students. For this study, what is the independent variable

Answers

Answer:

Consumption of moderate doses of St. John's Wort

Step-by-step explanation:

A variable that changes without depending on the other variable is called the independent variable and the variable that changes relative to the independent variable is called the dependent variable.

Here the effect of St. John's Wort on memory is being studied.

So, the independent variable would be the consumption of moderate doses of St. John's Wort and the dependent variable would be the effect it has on the person's memory.

John has $5 in his bank account when he gets a job. He begins making $109 a day. A student found that the equation that represents this situation is y = 5x + 109.

Answers

Answer:

the student answer is incorrect

Correct answer: y = 109x + 5

Step-by-step explanation:

He STARTS with $5, which means it says aside. Since he REPEATEDLY recieves $109 EVERY day, it is as 109x because you don't know how much days there are. So the correct equation is y = 109x + 5.

Hope this helps!

Answer:

x = 18

Step-by-step explanation:

2x/ 3 - 7 = 5 (multiply both sides by 3 to get rid of the 3 under the 2x)

2x - 21 = 15 ( add 21 to both sides)

2x = 36 (divide both sides by 2)

x = 18

Where: [tex]a \to[/tex] Real part and

[tex]bi \to[/tex] Imaginary part

From the given numbers, [tex]4 + 9i[/tex] is a complex number

The given numbers are:

[tex]2 + \sqrt 3[/tex]

[tex]4 + 9i[/tex]

[tex]\pi[/tex]

By comparing [tex]a + bi[/tex] with the given numbers;

We can conclude that: [tex]4 + 9i[/tex] is a complex number

Because it has a real part (4) and an imaginary part (9i)

3x - y = 6
3x = 6 + y
y = 3x - 6, slope = 3
Y = 3x + b
-6 = 3(-4) + b
-6 = -12 + b, b = 6
Solution: y = 3x + 6

Answer:

the desired equation is 3x - y = -6

Step-by-step explanation:

Recall that parallel lines have the same slope. Thus, the desired line has an equation of the form 3x - y = C, where C is determined by the coordinates of the point (-4, -6).

3x - y = C becomes 3(-4) - (-6) = C after substitution of -4 and -6 for x and y respectively. Then -12 + 6 = C, and C = -6.

Thus, the desired equation is 3x - y = -6

Answer:

perimeter = 2(8x+3) + 2(5) area= (8x+3) • 5

Step-by-step explanation:

perimeter = 2(length) + 2(width)

if length equals (8x+3) and width equals 5 then you would just plug those numbers into the equation which gives you...

perimeter = 2(8x+3) + 2(5)

area = length • width

like i previously said above if length equals (8x+3) and width equals 5 than you would just plug those numbers into the equation which gives you...

Answer: She has 5/12 left of her book to read as well

Step-by-step explanation:

Martha read 1/6 books on Saturday and 5/12 books on Sunday, then the books left to read will be 5/12.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given information in the question,

Books read by Martha on Saturday = 1/6

Books read by Martha on Sunday = 5/12

Then, the number of books left to read is,

1 - (1/6 + 5/12)

Take LCM as 12,

[12 - (2 + 5)]/12

= (12 - 7)/12

= 5 / 12

The graph shows the square root of the parent function. which statement is true?
A. 0,0) is the x- and y-intercept of the function
B. 0,1) is the x- and y-intercept of the function
C. This function has no intercepts
D. 1,1) is the x- and y-intercept of the function

Answers

Answer: A is correct

Step-by-step explanation:

The graph shows the square root of the parent function and function has no intercepts

What is the parent function?

A parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.

What are intercept?

Using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

According to the question

Graph shows the square root of the parent function.

i.e ,

y = [tex]\sqrt{x}[/tex]

As,

This equation will never touch the x-axis or the y-axis, so the function does not have an x- or y- intercept.

Therefore,

This function has no intercepts ,

Hence, The graph shows the square root of the parent function and function has no intercepts .

Count the rise over run from somewhere the line is matched up with a whole point, like 20 or 60. The next place the point is a whole (if starting from 20) is 60. Run is 4. The Rise from 20 to 60 is 1

Answer:

[tex]\frac14[/tex]

Step-by-step explanation:

Hello!

Slope can be calculated by the formula [tex]\frac{Rise}{Run}[/tex].

Rise is the change in y between two pointsRun is the change in x between two points

We need two points to calculate the slope.

The two points I'm picking are (20,10) and (60,20)
