Answer:
a. 2.13. b. (30.53, 34.79). c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.
Explanation:
The size of the sample is 42 and the mean of the sample is ∑
= 32.66 and the standard deviation of the sample (σ) is √[∑(
-μ)^2 - 1] = √46.6092 = 6.8271
a. α = 1 - (95/100) = 0.05; α/2 = 0.025; the degree of freedom = n-1 = 42-1 = 41; tα/2 = t0.025 = 2.02. Thus, the error margin = (tα/2)*(σ/√n) = 2.02*(6.83/√42) = 2.1279
b. Lower level limit = 32.66 - 2.1279 = 30.5321; Upper level limit = 32.66+2.1279 = 34.7879. The interval estimate = (mean± margin of error) = (30.53, 34.79).
c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.
Answer: 9.7%
Explanation:
Given Data
Rf = Risk free return = 6%,
Rpm = Risk premium = 4%,
Beta = 0.9
Wd = Debt = 20%
rd = cost of debt = 8%
We = equity = 80%
Re = Rf + Beta (Rpm)
= 0.06 +0.9 (0.04)
= 0.096 * 100
= 9.6%
Unlevered Equity Cost ;
ReU= Wd × rd + We × re
= 0.20 × 8% + 0.80 × 9.6%
= 9.28%
Levered Equity Cost:
New Debt = 60%,
New Equity = 40%,
New rd = 9%
ReL = ReU + (ReU - rd) (D ÷ E)
= 9.28% + (9.28% - 9%) (0.60 ÷ 0.40)
= 0.097 * 100
= 9.7%
Answer:
They were 10 friend
Explanation:
We can construct the equation system as follows:

we can solve for the number of friend by using subtritution:






we get a quadratic formula we solve for the positive root
f = 10
We know check if the root is correct:
800 / 10 = 80
800 / (10 - 2) = 100
Answer:
The answer is Instrumental behavior. It is an action performed to reach a goal, such as to obtain a food item, achieve some other kind of reward, or remove a punishment; the behavior causes the desired outcome. Problem-solving is a subset of instrumental behavior, invoked when a direct action (such as reaching for an object) cannot achieve the goal and an indirect approach must be used (such as opening a container to get the object). To paraphrase Thorndike, a problem exists when the goal that is sought is not directly attainable by the performance of a simple act available in the animal's repertoire.

Can totally vary. Normally, it can create 1,000 dollars up to 2,000 dollars if it's a good investment.
