Do you think that the 330 triathletes who responded to the survey may be considered a random sample from the population of triat

PSYCHO15rus [73]

Depending on how many could have taken the survey, it would be a random sample of the population of triathletes. However, if these surveys were conducted at a single event that was in an area where only a small range or area of triathletes attended, it may not be a good random sample.

When the price of candy bars is $1.00, the quantity demanded is 500 per day. When the price falls to $0.80, the quantity demande

Wittaler [7]

Answer:

The demand for candy bars is inelastic

Explanation:

The midpoint rule calculate the price elasticity of demand as percentage change in quantity divided by the percentage change in price:

<u>% change in quantity </u>

$\frac{Q_2-Q_1}{ \frac{Q_2 + Q_1}{2} } \times 100$

The quantity demanded increased from 500 to 600. We have

$Q_1 = 500 \: and \: Q_2 = 600$

$\implies \frac{600 - 500}{ \frac{600 + 500}{2} } \times 100 \\ = \frac{100}{ \frac{1100}{2} } \\ = \frac{100}{550} \\ = \frac{2}{11}$

<u>% change in price</u>

$\frac{P_2-P_1}{ \frac{P_2 + P_1}{2} } \times 100$

The price changed from 1 dollar to 0.8 dollars.

$\frac{0.8 - 1}{ \frac{0.8 + 1}{2} } = - \frac{2}{9}$

Price elasticity if demand is

$\frac{ \frac{2}{11} \%}{ - \frac{2}{9} \%} = - \frac{9}{11} = - 0.82$

The negative sign tells us that there is an inverse relationship between price and quantity demanded.

Since 0.82 is less than 1, the demand for candy bars is inelastic

Jack's manufacture company have experienced inflation for the past three years as follows: the first year's periodic inflation r

ankoles [38]

Answer:

8.09%

Explanation:

Year Inflation rate 1 + Inflation rate

1 0.03 1.03

2 0.04 1.04

3 x 1+x

Average rate 0.05 0.05

1 + Average rate = [(1+r1)*(1+r2)*(1+r3)]^(1/3)

1.05 = [1.03*1.04*(1*x)]^(1/3)

[1.0712*(1+x)] = (1.05)^3

[1.0712*(1+x)] = 1.157625

1 + x = 1.157625 / 1.0712

1 + x = 1.080681

x = 1.080681 - 1

x = 0.080681

x = 8.09%

Thus, the periodic Inflation rate in year 3 is 8.09%

andre [41]

Answer:

The correct answer is: Chain.

Explanation:

A chain network is a hierarchical structure in which each component of the chain or employee must transmit a message to its immediate hierarchical coworker. Chain networks can flow upwards or downwards in both cases working with the same pace of communication. Chain networks are usually implemented in bureaucratic institutions where the hierarchical structure is well-defined and the decision-making is centralized.

Terri, age 16, is a dependent of her parents in 2020. During the year, Terri earned $5,000 in interest income and $3,000 from pa

aleksandrvk [35]

Answer:

A. $4,650

B. $1,750

C. $2,900

Explanation:

A. Calculation to determine Terri's taxable income

TAXABLE INCOME

Earned income $3,000

Add Unearned income $5,000

Gross income & AGI $8,000

($3,000+$5,000)

Less: Standard deduction ($3,350)

(Greater of either $3,000 or $1,050 income earned +$350)

Taxable income $4,650

($8,000-$3,350)

Therefore Terri's taxable income is $4,650

b. Calculation to determine How much of Terri's income is taxed at her rate

TAXED AT TERRI'S RATE

Taxable income $4,650

($8,000-$3,350)

Less: amount taxed at parents' rate ($2,900)

($5,000-$2,100)

Taxed at Terri's rate $1,750

Therefore The amount of Terri's income that is taxed at her rate is $1,750

c. Calculation to determine How much is taxed at her parent's rate

TAXED AT PARENTS' RATE:

Net unearned income=$5,000-$2,100

Net unearned income= $2,900

($5,000-$2,100)

Therefore The amount of Terri's income that is taxed at her parent's rate is $2,900
