Answer:

Step-by-step explanation:

340/25 = 13.6 = 13 hours and 10 min

30 x 13.6 = 408 hours

25x+30y= 340 and y=2x can be used to determine the number of hours cooper worked and the number of hours isaiah worked. Where x Isaiah 's working hours and y is cooper's working hours.

Step-by-step explanation:

Isaiah ironing rate per hour = 25 shirts

Cooper ironing rate per hour = 30 shirts

Total shirts pressed = 340

Let,

Isaiah´s number of hours = x

Cooper's number of hours = y

According to given statement;

25x+30y=340   Eqn 1

Hudson worked twice many hours as grace.

y = 2x    Eqn 2

<u>Define Variables:</u>

Let x = the number of hours Isaiah worked

Let y = the number of hours Cooper worked

Isaiah can iron 25 shirts each hour, so in x hours he can iron 25x shirts. Cooper can iron 30 shirts each hour, so in y hours he can iron 30y shirts. The total number of shirts ironed 25x+30y equals 340

Since Cooper worked twice as many hours as Isaiah, Cooper worked <em>more </em>hours, so if we multiply 2 by the number of hours Isaiah worked, we will get the number of hours Cooper worked, meaning y equals 2x.

<u>System of Equations:</u>

25x + 30y = 340

y = 2x

vitfil [10]

Answer:

x=-9

Step-by-step explanation:

5x+8-3x=-10

Simplify to get 2x+8=-10

Find what 2x equals to by taking away 8, 2x = -18.

Divide by 2 to find x, x = -9

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to *
torisob [31]

Answer:

10

Step-by-step explanation:

Coefficient of variation is a measure of dispersion, showing the variability of data in relation to the mean.

The Coefficient of variation compares the degree of variation between data points. The coefficient of variation is the ratio of mean to standard deviation. It is given by the formula:

Coefficient of variation = mean / standard deviation

Coefficient of variation = 50 / 5

Coefficient of variation = 10
