Answer:
$378.39
Step-by-step explanation:
The balance was $294 for 7 days, $453 for 16 days, $303 for 8 days, so the average daily balance is ...
(7(294) +16(453) +8(303))/(7+16+8) = 11730/31 = 378.39
The average daily balance for the billing period was $378.39.
You group the like terms and multiply, and remember that when you multiply two like terms like x^4 times x^3 you ADD the exponents, so you would have x^7.
For this problem:
so for the x's: -3x^2(4x^3) = -12x^5;
now for the y's: y^2(y^4) = y^6;
so your final answer is -12x^5y^6
Answer:
Get a list of all the music students in the eighth grade. Randomly select enough students to get a sample from the population. Ensure that the selection is completely random so the sample is not biased.
Answer:
I'll just answer all three for you. Part A: y=5x+0 Part B: $32.50. Part C: 9 hours and 30 minutes.
Step-by-step explanation:
Part A: The $5 is the independent variable, because it adds every hour. So the equation is y=5x+0, because hse starts with no money at the begginning.
Part B: 5x6.5=32.50.
Part C: 5x9.5=47.50
