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.

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:

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.

The city will have 201 streetlights at the end of 32 weeks

Step-by-step explanation:

Here, we want to know the number of streetlights that the city will have at the end of 32 weeks

From the question, it is expected that 2 additional streetlights will be installed at the end of each week

So the number installed at the end of 32 weeks will be 32 * 2 = 64

So the number of streetlights at the end of 32 weeks will be;

64 + 137 = 201 streetlights

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:

Area of another sector=[tex]53.0292 in^2[/tex]

Perimeter of another sector=29.36 in

Step-by-step explanation:

We are given that

Radius, r=8.26 in

Arc length , l=12.84 in

Area of circular sector=[tex]\frac{arc\;length} {Circumference\;of\;circle}\times \pi r^2[/tex]

Area of circular sector=[tex]\frac{l}{2\pi r}\times \pi r^2=\frac{l}{2}\times r[/tex]

Where Circumference of circle=[tex]2\pi r[/tex]

Substitute the values

Area of circular sector=[tex]\frac{12.84}{2}\times (8.26}[/tex]

Area of circular sector=[tex]53.0292 in^2[/tex]

Area of another sector=[tex]53.0292 in^2[/tex]

Perimeter of circular sector=8.26+8.26+12.84

Perimeter of circular sector=29.36 in

Perimeter of another sector=29.36 in

As the radius of a sector decreases, the arc length increases to have an

equal area with a sector with a radius that is longer.

The measurements of another sector with the same perimeter and area are;

Reasons:

Radius of the sector, r = 8.26 inches

Arc length of the sector = 12.84 inches

Perimeter of sector = 2·r + Arc length

Perimeter of the given sector = 2 × 8.26 inch + 12.84 inch = 29.36 inch

Circumference of the circle = 2 × 8.26 × π = 16.52·π

Area of the given circle, A = π × 8.26² = 68.2276·π

Area of the sector, A = 53.0292 inch²

Therefore, we have;

2·R + A = 29.36 inches

[tex]\displaystyle \mathbf{\frac{A}{2\cdot \pi \cdot R} \times \pi \cdot R^2} = 53.0292[/tex]

A·R = 53.0292 × 2

[tex]\displaystyle New \ arc \ length, \ A = \mathbf{\frac{53.0292 \times 2}{R}}[/tex]

Which gives;

[tex]\displaystyle 2 \cdot R + \frac{53.0292 \times 2}{R} = 29.36[/tex]

[tex]\displaystyle R + \frac{53.0292 }{R} = 14.68[/tex]

R² + 53.0292 = 14.68·R

R² - 14.68·R + 53.0292 = 0

Factorizing with a graphing calculator, gives;

(R - 6.42)·(R - 8.26) = 0

R = 6.42 or R = 8.26

The measurement of R = 8.26 is for the first sector

Given that the sectors are different, we have;

The arc length, A = 29.36 - 2·R

∴ A = 29.36 - 2 × 6.42 = 16.52
