In this scenario, we'll define the following variables:
x: total volume of potting soil in liters.
y: quantity of potting soil allocated to each pot in liters.
To determine the number of pots, we can use the expression:
Substituting in the respective values yields:
Reformatting gives us:
When rounding down to the nearest whole number, we find:
The conclusion is:
Yao Xin is capable of filling 18 pots.
Response:
MAD value comes out to be 3.
Detailed Breakdown:
The given sales forecasts for the last four months are 5, 6, 11, and 12 units.
To calculate the Mean Absolute Deviation (MAD) for these forecasts:
The average of the forecasts across four months is
.
Thus, the total of absolute differences between the forecast values and the average is = |5 - 8.5| + |6 - 8.5| + |11 - 8.5| + |12 - 8.5| = 3.5 + 2.5 + 2.5 + 3.5 = 12.
Hence, the MAD value will be =
(Final Answer)
Y = 6
Here’s a step-by-step explanation:
On the initial day of ticket sales, the school sold 3 adult tickets and 8 student tickets for a total of $72.
On the following day, the school collected $152 from 7 adult tickets and 16 student tickets.
What is the price of a student ticket?
Day 1: 3x + 8y = 72
Day 2: 7x + 16y = 152
This leads to a system of equations.
By manipulating these equations, we find:
Ultimately, y = 6.
If you wish to continue from this point, substituting y into the equation will give the value for x.
Detailed explanation:
Question 4 provides clear information,
thus resolving Question 4:
1 euro equals $1.17.
Consequently, €20.46 is calculated as 20.46 multiplied by 1.17, which equals $23.93.
1 pound equals $1.28.
Thus, £12.60 translates to 12.60 multiplied by 1.28, yielding $16.128.
Therefore, the MP3 in pounds is $7.81 cheaper in dollars.
