Answer:

Gross income = $38500

Adjusted gross income = $35800

Taxable income = $13000

Step-by-step explanation:

1. Gross income = wages + interest received

Gross income = $36,300 + $2200

Gross income = $38500

2. Adjusted gross income = Gross income - adjustments

Adjusted gross income = $38500 - $2700

Adjusted gross income = $35800

3. Taxable income = adjusted income - (exemption + deductions)

Taxable income = $35800 - ($4050 + $6300 + $7800 + $2900 + $1750)

Taxable income = $35800 - $22800

Taxable income = $13000

Complete Question

In response to concerns about nutritional contents of fast foods, McDonald's has announced that it will use a new cooking oil for its French fries that will decrease substantially trans fatty acid levels and increase the amount of more beneficial polyunsaturated fat. The company claims that only 3 out of 100 people can detect a difference in taste between the new and old oils. Assuming that this figure is correct (as a long-run proportion), what is the approximate probability that in a random sample of 1000 individuals who have purchased fries at McDonald's, at least 40 can taste the difference between the two oils? (2.5 pts.)

Answer:

The probability is  [tex]P(\^ p \ge 0.04 ) = 0.03216[/tex]

Step-by-step explanation:

From the question we are told that

   The population proportion is  [tex]p = \frac{3}{100} = 0.03[/tex]

    The sample size is  n  = 1000

 Generally the mean of this sampling distribution is  [tex]\mu_{x} = 0.03[/tex]

Generally the standard deviation of this sapling distribution is  mathematically evaluated as  

        [tex]\sigma = \sqrt{\frac{p (1 - p)}{n} }[/tex]

=>      [tex]\sigma = \sqrt{\frac{0.03 (1 - 0.03)}{1000} }[/tex]

=>      [tex]\sigma = 0.0054[/tex]

Generally the sample proportion when the number of those that can taste the difference is 40  is mathematically represented as

      [tex]\^ p = \frac{40}{1000} = 0.04[/tex]

Generally the approximate probability that in a random sample of 1000 individuals who have purchased fries at McDonald's, at least 40( [tex]\^ p = 0.04[/tex]) can taste the difference between the two oils is mathematically represented  as

     [tex]P(\^ p \ge 0.04 ) = 1 - P(\^ p < 0.04 )[/tex]

Here

      [tex]P(\^ p < 0.04 ) = P(\frac{ \^ p - \mu_{x}}{\sigma } < \frac{0.04 - 0.03}{0.0054} )[/tex]

[tex]\frac{\^ p -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ \^ p )[/tex]

=>   [tex]P(\^ p < 0.04 ) = P(Z < 1.85 )[/tex]

From the z table the probability of  (Z < 1.85  ) is

      [tex]P(Z < 1.85 ) = 0.96784[/tex]

So

    [tex]P(\^ p < 0.04 ) = 0.96784[/tex]

So

   [tex]P(\^ p \ge 0.04 ) = 1 - 0.96784[/tex]

=> [tex]P(\^ p \ge 0.04 ) = 0.03216[/tex]

Answer:

x i a 90 degree anglt

Step-by-step explanation:

Answer:

80

Step-by-step explanation:

Sum of all angles = 360°

85° + x + 35° + 2x = 360°

3x + 120° = 360°

3x = 360° - 120°

3x = 240°

x = 80°

Answer:

The critical value tα/2 that corresponds to a​ 98% confidence level with 1000 degrees of freedom is 2.33.

Step-by-step explanation:

From the question we are told that

   The critical value is  [tex]t_{\frac{\alpha }{2} } = 2.33[/tex]

From the student's t distribution table the probability of     [tex]( t > 2.33)[/tex] at a degree of freedom of  1000 is  

        [tex]\frac{\alpha }{2} = (t > 2.33 ) = 0.01[/tex]

Hence the level of significance is mathematically evaluated as

        [tex]\alpha = 2 * 0.01[/tex]

=>    [tex]\alpha = 0.02[/tex]

Generally the confidence level  is mathematically represented as

      [tex]C = 1- \alpha[/tex]

=>  [tex]C = 1- 0.02[/tex]

=>  [tex]C = 0.98[/tex]

Converting to  percentage

=>  [tex]C = 0.98 * 100[/tex]  

=>  [tex]C = 98\%[/tex]

Answer:

38 cubes

Step-by-step explanation:

The volume is calculated by multiplying the length x width x height. So the volume of this box is 30 cm3.

Assuming the cube is 1 x 1 x 1 (volume= 1cm3), then 30 cubes would be able to fit into the box. (30/1 = 30)

However, if the cube is 2x2x2, it would be able to fit 8 cubes.

Answer:

15x20/300

Step-by-step explanation:

you multiply 15 and 20 then didvide that answer to 300

These are the  points (20,0), (0,20), (20,5) are a few points which represent the number of hours a student can work each job to meet his goal.

Let ;

The hour spent in mow lawns is represent by x,

And represent the hour spent for gardening by y.

According to the question;

He charges $15 per hour to work mow lawns .

And $20 per  hour to gardening .

Total no. of hours allowed to work = 20 hours per week

Then the inequality to represent the cost constraint will be,

15x+20y ≥ 300

Since,

He cannot work for more than 15 hours per week, the inequality to represent the time constraint will be,

x + y ≤ 20

On solving the inequalities,

15(20-y) + 20y = 300

300 - 15y + 20y = 300

5y= 0

y = 0

For value of x put y = 0

x + 0 = 20

It states if he work only in mows law for 20 hours he can earn $15 =(15)(20) =$300

All pairs of positive numbers whose sum is less than 20, are solutions to the given system of inequalities.

A pair of negative numbers will also solve both constraints, but is not applicable in this situation because a student, cannot work for negative hours, or  for a negative amount of money.

So, (20,0), (0,20), (20,5) are a few points which represent the number of hours a student can work each job to meet his goal.
