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.

Determine from the balanced chemical reaction if
the derived mole ratio is correct or incorrect.
It's incorrect. There are 6 moles of NaBr produced for every 3 moles of Na₂S among the reactants (as well as 2 moles of FeBr₃), so the mole ratio of NaBr to Na₂S should be 2 : 1, not 1 : 1.

You are hiking in the woods at a rate of 3 mph. The function y=3x describes how many miles y you walk in x hours. create an input table with 3 domain values
Answer:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
Step-by-step explanation:
Given
[tex]y = 3x[/tex]
Required
Create a table that represents this scenario
Because x represents time, x can not be negative. So, the domain of x is:
[tex]x \geq 0[/tex]
Assume [tex]x = 1[/tex]
[tex]y = 3 * 1 = 3[/tex]
Assume x = 4
[tex]y=3*4 = 12[/tex]
Assume x = 6
[tex]y=3*6 = 18[/tex]
Hence, the table is:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18

Identify which of these types of sampling is​ used: random,​ systematic, convenience,​ stratified, or cluster. To determine her stress level​, Charlotte divides up her day into three​ parts: morning,​ afternoon, and evening. She then measures her stress level at 2 randomly selected times during each part of the day.
Answer:
stratified sampling
Step-by-step explanation:
Note, in the stratified sampling sample method, the population is divided into smaller strata or smaller groups, and then a sample is selected randomly.
In this scenario, the population is a day (24 hours), so dividing the population (day) into three parts; morning, afternoon, and evening represents the various strata. Hence, since Charlotte, the researcher measures her stress level at 2 randomly selected times during each part of the day, she would be using the stratified sampling method.

Find the value of x in the
following parallelogram:
2x
х
х
2x
Answer:
60°
Step-by-step explanation:
The sum of the angles in any quadrilateral is 360°. In a parallelogram the sum of neighboring angles is 180°. Therefore:
2x + x = 180°
3x = 180°
x = 60°
The value of x is 60.
What is properties of parallelogram?Parallel sides define an object.Congruent opposites are present.Angles at opposites are congruent.Consecutive angles on the same side called supplementary angles.A parallelogram is divided into two congruent triangles by each of its diagonals.A parallelogram's diagonals cut each other in half.Given:
Angles x, x, 2x, 2x.
Using the property of parallelogram, the adjacent angles of parallelogram sum to 180.
x+ 2x= 180
3x= 180
x= 180/3
x= 60
Hence, the value of x is 60.

The margin of error will be 5. Option C is corect.
What is the margin of error?
In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings.
The interval is;
(35,45)
Half of the breadth of the total confidence interval is the margin of error.
MOE = (45-35)/2
MOE =5
The margin of error will be 5.
Hence option C is corect.

Answer:
D : Obtuse
Step-by-step explanation:
A right angle is 90 degrees.
An acute and obtuse angle are found by looking at the angle between the sides being looked at.
If the angle is GREATER i.e. Angle > 90 , then it is obtuse.
If the angle is LESS THAN i.e. Angle < 90 , then it is acute.
This angle is apparently greater than 90 degrees and therefore is obtuse.

During a thunderstorm, 4
inches of rain fell in 2 1/2
hours. What was the rate of rainfall in inches per hour?
Answer: 1.6 in per hour
Answer:
hourly rate.
Step-by-step explanation:
As others have noted, it is a simple mathematical division problem (4/2.5) and the average is 1.6 inches per hour.
However, if this is for sizing civil works such as culverts or plumbing storm water drainage systems to mitigate flooding, the highest rate per hour must be known and usually the highest ten minutes rainfall rate expressed as an hourly rate.
For example, if 4.0 inches fell over that 2.5 hours, nothing says that a rain band did not dump 3 inches in the first hour, (3 inches per hour cumulative) or 0.75 inches in a ten minute period (4.5 inches per hour rate), with the remainder of the storm tapering off to lesser rates. So the average is correct, but the peak hour is much more important for practical purposes.
