Assuming that the 4.8% interest rate is an annual interest rate, then, after one year, with a principal of $3,000 we would be able to win 4.8% of $3000:
![3000\times\frac{4.8}{100}=144](https://tex.z-dn.net/?f=3000%5Ctimes%5Cfrac%7B4.8%7D%7B100%7D%3D144)
Divide 144 over 12 to find the monthly earnings:
![\frac{144}{12}=12](https://tex.z-dn.net/?f=%5Cfrac%7B144%7D%7B12%7D%3D12)
Therefore, with a principal of $3,000 we would be earning $12 interest in 1 month.
For the earnings on the first month to be equal to $10, then you would have to win $120 annually, and $120 must be 4.8% of the principal. To find which quantity satisfies that 4.8% of it is equal to $120, divide 120 over 4.8%:
![\frac{120}{4.8\text{ \%}}=\frac{120}{(4.8/100)}=\frac{100}{4.8}\times120=2500](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B4.8%5Ctext%7B%20%5C%25%7D%7D%3D%5Cfrac%7B120%7D%7B%284.8%2F100%29%7D%3D%5Cfrac%7B100%7D%7B4.8%7D%5Ctimes120%3D2500)
Therefore, the principal must be equal to $2500 for you to win $10 on the first month, and it would indeed be correct to say that if you open an account with $3000 you will earn at least $10 interest in 1 month.

Step-by-step explanation:
Answer:
809.4cm²
Step-by-step explanation:
Given the following :
Systematic error = 3.8cm (The measured length is always more than the actual length.)
Most probable dimension :
Width = 85.7 cm
Length = 123.5 cm
Hence most probable area of Rectangle :
Area = Length × Width
Area = 85.7cm × 123.5cm = 10583.95 cm²
Dimension due to Systematic error :
Length = (85.7cm + 3.8cm) = 89.5cm
Width = (123.5cm + 3.8cm) = 127.3cm
Area = Length × width
Area = ( 89.5cm × 127.3) = 11393.35cm²
Systematic error of the area :
value of area with Systematic error - Probable value of area :
11393.35cm² - 10583.95 cm² = 809.4cm²
