Simply just multiply 9 days by 3 meals by 2 people. it's 54
The answer to your question would be true.
Similarly to fact that a two-order uses two equations, and a three-order system uses three, so a four-order uses four. Basically, just remember that the number of equations matches the number of the order.
Solution :
Transforming given equations :
From above equations we can see that equation 1) has largest percentage growth rate and the percent growth rate is 12% .
Hence, this is the required solution.
Answer:
Standard Deviation = 5.928
Step-by-step explanation:
a) Data:
Days Hours spent (Mean - Hour)²
1 5 61.356
2 7 34.024
3 11 3.360
4 14 1.362
5 18 26.698
6 22 84.034
6 days 77 hours, 210.834
mean
77/6 = 12.833 and 210.83/6 = 35.139
Therefore, the square root of 35.139 = 5.928
b) The standard deviation of 5.928 shows how the hours students spend outside of class on class work varies from the mean of the total hours they spend outside of class on class work.
The number is 30
100%=70 x%=21
Solve for the equation and it gets 30
