Answer:

There are 5 black counters in the bag.

Step-by-step explanation:

15 green counters in the bag

The proportion of green counters is given by:

[tex]p = 1 - (\frac{1}{3} + \frac{1}{6}) = 1 - (\frac{2}{6}+\frac{1}{6}) = 1 - \frac{3}{6} = 1 - \frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}[/tex]

So, we have that, the total is x. So

[tex]\frac{x}{2} = 15[/tex]

[tex]x = 30[/tex]

There are 30 total counters.

How many black counters are in the bag ?

A sixth of the counters are black. So

[tex]\frac{1}{6} \times 30 = \frac{30}{6} = 5[/tex]

There are 5 black counters in the bag.

Step-by-step explanation:

        a). It will take 16 hours to earn $144.

        b). It will take 24.67 hours to earn $222

        c). In a 40 hours week he will earn $360.

             In a 7 hours day he will earn $63.

          Proportionality law states,

          y ∝ x

          y = kx  [here, k = proportionality constant]

If Adam earns $36 in 4 hours,

36 = 4k

k = 9

Therefore, expression for total earnings will be,

y = 9x

a). For y = $144,

    144 = 9x

     x = 16 hours

b). For y = $222,

    222 = 9x

     x = 24.67 hours

c). For 40 hour week,

    y = 9(40) = $360

    Adam will earn $360 in a week by the rate $9 per hour.

    For 7 hour day,

    y = 9(7) = $63

    Adam will earn $63 in a day by the rate of $9 per hour.

            Therefore, a). It will take 16 hours to earn $144.

                               b). It will take 24.67 hours to earn $222.

                               c). In a 40 hours week he will earn $360.

                                    In a 7 hours day he will earn $63.

Answer:

Step-by-step explanation:

Given:

Width of a garden = 10 feet

Length of the garden = 14 feet

Area of the garden and the walkway together = 396 square feet.

To find:

The width of the walkway.

Solution:

A cement walkway is added around the outside of the garden.

Let x be the width of the walkway.

The width of the garden with walkway = 10+2x

The length of the garden with walkway = 14+2x

Area of a rectangle is

[tex]Area=length\times width[/tex]

Area of garden and the walkway together is

[tex]Area=(14+2x)\times (10+2x)[/tex]

[tex]396=140+28x+20x+4x^2[/tex]

[tex]396=140+48x+4x^2[/tex]

[tex]396=4(35+12x+x^2)[/tex]

Divide both sides by 4.

[tex]99=35+12x+x^2[/tex]

[tex]0=35-99+12x+x^2[/tex]

[tex]0=-64+12x+x^2[/tex]

Splitting the middle term, we get

[tex]x^2+16x-4x-64=0[/tex]

[tex]x(x+16)-4(x+16)=0[/tex]

[tex](x+16)(x-4)=0[/tex]

Using zero product property, we get

[tex](x+16)=0\text{ and }(x-4)=0[/tex]

[tex]x=-16\text{ and }x=4[/tex]

Width of walkway cannot be negative. So, x=4.

Therefore, the width of the walkways is 4 feet.

Answer:

The price of the robotics kit should be $34 dollars

Step-by-step explanation:

First we have to find out what 25% and 15% of 40 is.

25% of 40 = 10

15% of 40 = 6

Next we have to add 10 plus 6 then subtract 40 by it.

10 + 6 = 16

40 - 16 = 34

So, the robotics kit should cost 34 dollars after both discounts.

Answer:

The 99% confidence interval for the mean time spent waiting in line by all passengers at this airport is between 12.84 minutes and 23.16 minutes. It means that we are 99% sure that the truw mean waiting time for all passengers in this airport is in this interval.

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 36 - 1 = 15

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.947

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.947\frac{7}{\sqrt{16}} = 5.16[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 18 - 5.16 = 12.84 minutes

The upper end of the interval is the sample mean added to M. So it is 18 + 5.16 = 23.16 minutes

The 99% confidence interval for the mean time spent waiting in line by all passengers at this airport is between 12.84 minutes and 23.16 minutes. It means that we are 99% sure that the truw mean waiting time for all passengers in this airport is in this interval.

Answer:

Original price was $2163

Step-by-step explanation:

Let original price be x

23% of x = 497.42

23/100 × x = 497.42

23x/100=497.42/1

Cross multipy,

23x × 1 = 497.42 × 100

23x=49742

x=49742/23

x=2,163 approximately

Answer:

The solution to the system of equations be:

(x, y) = (16, 2)

Step-by-step explanation:

Given the system of equations

2 + 2y = 6

2x - 3y = 26

Isolate y for 2+2y=6

2+2y=6

subtract 2 from both sides

2+2y-2 = 6-2

2y = 4

divide both sides by 2

2y/2 = 4/2

y = 2

now substitute y = 2 in 2x - 3y = 26

2x - 3y = 26

2x - 3(2) = 26

2x-6=26

add 6 to both sides

2x-6+6=26+6

2x = 32

divide both sides by 2

2x/2 = 32/2

x = 16

Therefore, the solution to the system of equations be:

(x, y) = (16, 2)
