Answer:
d. not raising her hand when the teacher asks a question.
Explanation:
Social loafing is having the tendency to do less effort while in a group compared to when you're alone.
Not raising your hand when teacher asks a question is such behavior, because you don't want to make it look like you're interested or working.
<u>Answers A and B are the opposite of social loafing,</u> since you would be paying attention and work publicly by assisting others.
<u>Answer C doesn't have a direct relationship with social loafing</u>, but a loafer will usually not sit in front of the class, he's sit in the back, trying to be ignored.
Complete question :
If the price of an apple is $0.50, the marginal utility per dollar spent for the fifth apple is:
Number of apples ____total utility
2__________________130
3__________________180
4__________________220
5__________________250
6__________________270
7__________________280
Answer:
60
Explanation:
The marginal utility simply refers to the change or extra satisfaction derived with change in consumption.
Hence, the marginal utility of the fifth apple equals :
Difference /change or extra satisfaction derived by consuming one more than 4 apples = (total utility of 5th apple - total utility of 4th apple)
= (250 - 220) = 30
Hence, marginal utility per dollar :
Marginal utility / price per apple
Price per apple = $0.5
Marginal utility of 5th apple = 30
Therefore,
30 / 0.5
= 60
H+ conc = antilog to negative pH
H+ conc of pH 3 = 1 x 10^-3 M
One unit pH change of the H+ concentration is by a factor of 10. Since pH 3 to pH 5 is 2 unit changes, pH 3 then has one hundred<span> times more H+ concentration than a pH of pH 5. </span>
