Response bias results from the possibility that not all sophomore students provided accurate information about their drug use, which will immediately result in the response bias because of false data.
What is response bias?
Response bias is a catch-all phrase for a variety of inclinations for participants to give misleading or inaccurate answers to queries. These biases are common in studies involving participant self-report, such as structured interviews or surveys. The validity of questionnaires or surveys can be significantly impacted by response biases.
The idea that human subjects do not passively respond to stimuli but rather actively integrate several sources of information to develop a response in a specific scenario is central to the concept that response bias can be induced or caused by a variety of causes. As a result, practically every element of an experimental condition has the ability to sway a respondent.
Explanation:
The remedy is to conduct a survey by licensed social workers since licensed social workers didn't explicitly ask sophomore students about drug use; instead, they interacted with the students as their friends before gathering the data.

solve w^4 - 18w + 81 = 0
Answer:
No solution
Step-by-step explanation:
You can solve this in a few ways. One way is to graph the equation, and the solution is the x-value of the point of intersection. Another way would be to factor, which is more difficult to complete with a square bigger than 2.
By graphing, you can see a parabola that never touches that x-axis, which means no solution.
6−2(8−x)=2x−10
l don't understand the question
Answer: x has infinite number of solutions
Step-by-step explanation:
6−2(8−x)=2x−10
6-16-2(-x)=2x-10
-10+2x=2x-10
2x-10=2x-10 ==> x has infinite number of solutions
Evaluate 2X^2 + 3X -10 for the domain of {-2, 3}
The values of the expression at the domain {-2, 3} are {-8, 4}
How to evaluate the expression for the domain?The expression is given as
2x^2 + 3x - 10
The domain of the function is given as
{-2, 3}
Rewrite the domain as
x = {-2, 3}
Next, we substitute these values of x in the expression 2x^2 + 3x - 10
So, we have
x = -2:⇒ 2(-2)^2 + 3(-2) - 10 = -8
x = 2:⇒ 2(2)^2 + 3(2) - 10 = 4
Hence, the values of the expression at the domain {-2, 3} are {-8, 4}

What is the major determinant of the permeability of a membrane to a specific ion?
The major determinant of the permeability of a membrane to a specific ion is "the quantity of open ion channels that are specific to that ion."
What is ion channels?Certain cells, known as excitable cells, are distinguished by their capacity to produce electrical signals.
Some key features regarding the open ion channels are-
Although there are many different types of excitable cells, such as neurons, muscle cells, & touch receptor cells, they all use ion channel receptors to transform chemical or mechanical messages in to the electrical signals.Whenever an ion channel is open, ions to move in a single-file fashion into and out of the cell. Individual ion channels are ion-specific, which means that they typically allow only one type of ion to pass via them. The amino acids that line a channel, as well as the physical width of the channel, determine which ions can pass from the cell's exterior to its interior, or vice versa.To know more about the ion channels, here

Answer: GoodMorning: )✨Ok so We should Know that The top number in a fraction is always considered a numerator, and that It shows the number of parts we have. The bottom number in a fraction is considered a denominator. It shows the total number of parts into which anything is divided. For example, in the fraction 8/7, 8 is the numerator and 7 is the denominator.
Step-by-step explanation: Like In this fraction 7/3, 7 is the numerator and 3 is the denominator. In the fraction 9/7, 9 is the numerator and 7 is the denominator.The value placed above the horizontal line in a fraction is called a numerator. It signifies the number of parts taken out of the whole. The numeric value below the vinculum of a fraction is called the denominator. It represents the total number of equal parts as a whole.

If participant A's batting common is .312 and he had 596 at-bats , what number of hits did he get?
The number of hits A got is 186 hits.
A player's batting average is calculated by dividing the number of hits by the number of at-bats.
Player A batting average = 0.312
Number of at-bats A did = 596
We have to find the number of hits A got.
0.312 = Number of hits / 596
Number of hits = 0.312 x 596
= 185.952 hits.
Rounding to a whole number we get,

1/2 is the likelihood of rolling an odd or even number in probability.
What is probability and how is it calculated?
According to the probability formula, the probability of an event occurring, or P(E), is equal to the proportion of positive outcomes to all outcomes. P(E) is defined mathematically as favorable outcomes divided by total outcomes.A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.The event "rolling an odd number" contains three outcomes. There are 6 equally likely outcomes in the sample space. Divide to find the probability of the event.

Cherries cost 4 dollars per pound.my mother r lb of cherries and my father bought 2 lb of cherries.how much more money did my mother spent on cherries than my father
Mother spent (4r - 8) dollars more on cherries than did the father.
An expression using numbers and related operations is called a numerical expression.
According to the question, a pound of cherries costs $4.
Mom purchased r pounds.
The price of the cherry is calculated as follows: 4r = weight x $/lb.
Father purchased 2 pounds, thus the price of the cherries is 4 (2), or $8.
We remove the smaller value from the higher value, which is 4r - 8, where r must be more than two. Given that the mother spent more money on cherries than the father, the mother's cost of cherries is a greater value.

The gas mileeage in miles per gallon is 44.69 miles per gallon
How to convert 19 Km/L to miles per litresWe'll begin by converting 19 Km/L to miles per litres. This can be obtained as follow:
Gas mileage (in Km/L) = 19 Km/LGas mileage (in mile per litres) =?1 Km/L = 0.621371 mile per litre
Therefore,
19 Km/L = (19 Km/L × 0.621371 mile per litre) / 1 Km/L
19 Km/L = 11.806 miles per lire
How to convert 11.806 miles per litre to miles per gallonWe can convert 11.806 miles per litre to miles per gallon as follow:
1 mile per litre = 3.78541178 miles per gallon
Therefore,

Step-by-step explanation:
You want the value of the expression 2f(-3)-f(4), given that f(x) = 3x²-x+ 5.
Function evaluationA function is evaluated by putting the argument where the variable is, and simplifying the result. Polynomials are often easier to evaluate if they are written in Horner form.
f(x) = 3x² -x +5
f(x) = (3x -1)x +5
The values we need are ...
f(-3) = (3(-3) -1)(-3) +5 = (-10)(-3) +5 = 35
f(4) = (3(4) -1)(4) +5 = (11)(4) +5 = 49
