Answer:
4. Demand characteristics.
Step-by-step explanation:
Demand characteristics refer to the situation where the subject of study change their behaviour according to what they think the experiment is about.
On the other hand experimenter bias, happens when the expertise of the experiment conducts the subject of the study indirectly. Volunteer bias, is thought to happen when there are volunteers on a study, who might have a different behaviour to the entire target group.
The answer to the question
<span>Decompose 6 107
There will be 2 ways, the Unit form and the standard form
Unit form – The place value form of the given number
=> 6 107
=> 6 thousands + 1 hundreds + 7 ones
=> 6 107
Standard form – Is the numerical form of the given number.
=> 6 107
=> 6000 + 100 + 7
=> 6 107
Since, this is a whole number, we no longer need to use the fraction. Fraction
is most likely applicable to decimal numbers.</span>
What we know:
-volume of 10,000 drops is 10 fluid ounces
Step 1: Divide 10,000 by 10 (to find how much we need to divide 10 by to get our answer)
10,000/10=1,000
Step 2: Divide 10 by 1,000 (to find our answer)
10/1,000=0.01
Our answer is 0.01. The volume of 10 drops of liquid is 0.01 fluid ounces.
The <em>x</em>-intercepts are the points on the plot of a function <em>f(x)</em> where the graph crosses the <em>x</em>-axis. In other words, they're the values of <em>x</em> that make <em>f(x)</em> = 0.
In this case, the <em>x</em>-intercepts are the two roots of the parabola,
(<em>x</em> - 4) (<em>x</em> - 5) = 0 … … … (this is what the hint is referring to)
==> <em>x</em> - 4 = 0 <u>or</u> <em>x</em> - 5 = 0
==> <em>x</em> = 4 <u>or</u> <em>x</em> = 5
The intercepts themselves are points (<em>x</em>, <em>f(x)</em>), so you can report them as (4, 0) and (5, 0).
