It's biased. Grumpy people have a right to have their opinions known just as well as cheerful people. Grumpy looks are momentary. They can be brought about (especially at a University) by math problems that are illusive, by girl friends (or boy friends), that are illusive, by something for lunch that was barely edible, by any number of things.
She should ask people on some sort of other scale that is more random.
Answer:
1 unit of X must be sacrifised to gain a unit of Y, with satisfying Budget Constraint .
Explanation:
Budget Line shows the product combinations that a consumer can buy with given prices & money income (spending all) . Equation : P1X1 + P2X2 = M
Price ratio slope of the budget line i.e = P1/P2 : shows the amount of a good needed to be sacrifised to gain a unit of the other good , given prices & income.
So, Price Ratio : PX / PY = 2 / 2 = 1 in this case; implies 1 unit of Good X is needed to be sacrifised to gain a unit of good Y with given prices & income.
Answer:
7.9%
Explanation:
The rate of return is the ratio of return to the amount invested.
Since the property earns $4,650 per month,
Therefore;
$4,650 × 12 = $55,800
To get the annual rate of return,
= Monthly returns on property/Value of profit×100%
= $55,800/$710,000
=7.9%
Answer: The answer is as follows:
Explanation:
Given that,
Total reserves = $200 billion
Required reserves = 12.5 % of checking deposits
Therefore,
(a) Money multiplier = 
= 
= 8
(b) Money supply = Money multiplier × Total reserves
= 8 × $200 billion
= $1,600 billion
(c) Now, if Fed increases the required reserves to 16% of deposits.
New Money multiplier = 
= 
= 6.25
New Money supply = Money multiplier × Total reserves
= 6.25 × $200 billion
= $1,250 billion
Money supply decreases to $1,250 billion.
Answer:P value = 1 - 0.9793 = 0.0207
Explanation:
we can use Z value and normal distribution to find P value. P value is the area of beyond the value of Z value
sample mean (x.bar) = $52.20
Population mean (U) = $50
Sample Standard deviation (Sd) =$ 6.10
sample (n) = 25
Z =
=
Z = 2.50/1.22 = 2.049280328 = 2.049
area (normal distribution table) = 0.9793
P value = 1 - 0.9793 = 0.0207
