Answer:

Jumper, y = 172

Shirt, x = - 105

Step-by-step explanation:

Let :

Shirt = x

Jumper = y

5x + 4y = 163 - - (1)

3x + 2y = 29 - - - (2)

Multiply (1) by 3 and (2) by 5

15x + 12y = 489 - - - (3)

15x + 10y = 145 - - - (4)

Subtract :

12y - 10y = 489 - 145

2y = 344

y = 344 / 2

y = 172

Put y = 172 in (3)

15x + 12(172) = 489

15x + 2064 = 489

15x = 489 - 2064

15x = - 1575

x = - 105

The values ;

Jumper, y = 172

Shirt, x = - 105

We weren't supposed to obtain a negative value, kindly check if the parameters given are correct.

Ulleksa [173]

Based on the net working capital and the current assets, the current ratio of the firm is 2.92

<h3>What is the firm's current ratio?</h3>

First, find the current liabilities:

= Current assets - Net working capital

= 3,500 - 2,300

= $1,200

The current ratio is:

= Current assets / Current liabilties

= 3,500 / 1,200

= 2.92

Julia makes friendship bracelets. She was recently given nine bracelets from different people. At Christmas, she plans to give a
sergey [27]

Answer:

The number of bracelets with she start are 48.

Step-by-step explanation:

Given:

Julia was recently given 9 bracelets. She plans to give 1/3 of her bracelets. She will be left with 23.

Now, we need to find with how many did she start.

Let the bracelets with she start be x.

She plans to give \frac{1}{3}ofx = \frac{x}{3}.

According to question:

x-9-\frac{x}{3}=23

On solving the equation:

\frac{3x-27-x}{3} =23

<em>Multiplying both sides by 3 we get:</em>

3x-27-x=69

2x-27=69

<em>Adding both sides by 27 and then dividing by 2 we get:</em>

x=48

Therefore, the number of bracelets with she start are 48.

Lady_Fox [76]

Answer:

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean is:

M = \frac{a+b}{2}

The standard deviation is:

S = \sqrt{\frac{(b-a)^{2}}{12}}

Arrival time of 9:18 am and a late arrival time of 9:41 am.

9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.

Mean:

M = \frac{a+b}{2} = \frac{0+23}{2} = 11.5

Standard deviation:

S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(23 - 0)^{2}}{12}} = 6.64

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes
