Answer: 332

Explanation:

Lowest value = $43,000

Highest value = $61,600

Range = ( HV - LV ) / 4

= ( $61,600 - $43,000 ) / 4

= $4650

Where p = $4650

Required sample size (n)

n = ( Za /2 × P/E )²........... equation 1

Using 95% confidence level

Za/2 = Z 1 - 0.95

= Z0.025

= 1.96 using Z-table

Substituting Z into equation 1

n = ( 1.96 × 4650/500 )²

= ( 1.96 × 9.3 )²

= 332.25

To the nearest whole number

= 332

The goals scored per game by a soccer team represent the first quartile for all teams in a league. what can you conclude about t
nirvana33 [79]

Actually the quartile represents in what rank or order the team is when all the goals per team is arranged in ascending order. So for example since the team is on the first quartile, so this means it is on the 25% of the ranking. Hence we can say that:

“the team scored fewer goals per game than 75% of the teams in the league”

you deposit $6000 in an account earning 2% interest compounded continuously. how much will you have in the account in 10 years?
Gre4nikov [31]

Future Value is $7,327.20

<h3>What is compound interest ?</h3>

Compound interest is the interest on deposits that is computed using both the original principal and the interest accrued over time.

It is thought that the concept of "interest on interest" or compound interest first appeared in Italy in the 17th century. Compared to simple interest, which is just charged on the principal amount, it will cause a sum to grow more quickly.

Money grows more quickly when it is compounded, and compound interest increases as the number of compounding periods increases.

CI formula :  A = P(1 + r/n)^nt

where,

P = principal balance,

r = interest rate,

n = number of times interest is compounded per time period and

t = number of time periods.

To solve this question :

A = P(1 + r/n)^nt

= 6,000 (1 + 0.02/12) 120

= USD 7,327.20

The profit, P, in dollars for manufacturing n units of a certain product is given by the formula P = 3n2 - 90n - 720. (Assume th
sesenic [268]

Answer:

n=40

Explanation:

We want to know the value of n when P=480

P=3n^2-90n-720\\480=3n^2-90n-720\\3n^2-90n-720-480=0\\3n^2-90n-1200=0\\3(n^2-30n-400)=0\\n^2-30n-400=0

From here, we can find the factors of the quadratic equation, we need two numbers that multiplied give -400 and added -30. Since they are factors of 400, we can choose -20x20 or -40x10. When adding -20 and 20 the result is zero, but the sum of -40 and 10 is -30. Then:

n^2-30n-400=0\\(n-40)(n+10)=0\\

The solutions of the quadratic equation aren-40=0 and n+10=0:

n_1=40\\n_2=-10

Since n is a positive integer:

n=40

An employee of a firm has a job where the employee can easily adjust the number of hours they work for the employer per year. Th
USPshnik [31]

Answer:

The answer to both a and b is in the explanation below

Explanation:

a) The increase in wage can either decrease or increase the hours worked. This is became an increase in wage has both substitution effect and income effect that work in different directions. Substitution effect An increase in wage increases the opportunity cost of leisure, thereby making the worker increase number of hours worked. Income effect The increase in wage also makers the worker richer, thereby making the worker decrease number of hours worked.

Since no information about worker's preferences is given, we do not Imow which effect will dominate the other effect and, therefore, we do not know what the net impact of the increase in wage will be.

b) The bonus will only have income effect. The bonus will make the workers richer, thereby making the worker decrease number of hours worked.

If in part a), the substitution effect and income effect are equal in magnitude, then there will be no change in the number of hours worked. The number of hours worked will remain the same at 2000 hours. Since the employer would be paying $5 extra on each hour worked, the cost to the employer of increase in wage would be $10,000 (=2000 x $5), which is the same as the bonus in part b).
