Answer:

This is not necessarily evidence that the proportion of Americans who are afraid to fly has  decreaseddecreased  because belowbelow  0.10 because the proportion of sample, is nothing very close to 0.10.

Explanation:

n = 1100

p = 0.10

Using the formula np(1-p), we will have

= 1100(0.10)*(1 - 0.10)

= 1100*0.10*0.90

= 99

99 ≥ 10

This satisfies normal distribution condition. That is, proportion of sample are normally distributed.

mihalych1998 [28]

The amounts and types of education tax credits that Ariana and John can take without modified AGI limitation are as follows:

              Amount of Education Tax     Type of Education Tax Credits

For Kai      $1,000 ($2,500 x 40%)        The American Opportunity Credit

For Angel $1,560 ($7,800 x 20%)        The Lifetime Learning Credit

Total tax credit = $2,560 ($1,000 + $1,560)

<h3>What are the American Opportunity Credit and the Lifetime Learning Credit?</h3>

Whereas the American Opportunity Credit (Kia's) covers only the first 4 years of post-secondary education at 40% of $2,500 per student because Kia is a half-time student, the Lifetime Learning Credit applies to graduate schooling (Angel's) and covers 20% of the first $10,000 paid for tuition.

We must note that no taxpayer can claim both the American Opportunity Credit and the Lifetime Learning Credit for the same student in the same tax year.

Thus, the total education tax credit that Ariana and John can claim for both Kai and Angel is $2,560.

e-lub [12.9K]

Answer:

Effect on income= $4,500 increase

Explanation:

Giving the following information:

Special offer: 9,000 units of product S51 for $20.50 a unit.

Direct materials $ 3.10

Direct labor 1.50

Variable overhead 6.40

The customer would like modifications made to product S51 that would increase the variable costs by $5.00 per unit and that would require an investment of $36,000 in special molds that would have no salvage value.

<u>Because it is a special offer, we will not have into account the fixed costs.</u>

Unitary variable cost= 3.1 + 1.5 + 6.4 + 5= $16

Investment= 36,000

Effect on income= 9,000* (20.5 - 16) - 36,000

Effect on income= 40,500 - 36,000

Effect on income= $4,500 increase
