1 answer:
Answer:
$619.75
Explanation:
This is a problem of future value with compounded interest.
The equation that describes the future value of an amount (P) deposited for a period of 'n' years at an annual rate (r) compounded quarterly is:
For a $550 investment at 4% per year for 3 years, the future value is:
In 3 years, Jose will have $619.75 available towards the down payment for his motorcycle.

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:
O The size of the labor force is 40 million
Explanation:
Given:
Participation rate is 75%
Unemployment rate is 10%
Employment rate is 67.5%
The number of employed is 27 million.
As the employment rate is 67.5% of the size of the labor force which means that 27 million people are employed, we can say that number of people are employed equals to 67.5 percent of the total size of the labor force and we can write it numerically as:
27 = size of the labor force 67.5%
27 = size of the labor force
27 = size of the labor force
Dividing both side by 0.675
Size of the labor force = 40 million
Therefore, (O The size of the labor force is 40 million) option is correct.
