(b) Estimate . Explain how you determined these amounts.
(c) Jade said that the amount of money Ebony took out of her account each day between Day 8 and Day 12 was the same amount of money she put into her account each day between Day 0 and Day 4. Recall that Day 12 is when the balance first reached $0. Without doing any calculations, how could you show Jade why that cannot be true?
Answer:
Step-by-step explanation:
a) On day 4, her balance = $400
on day 5, her balance = $0
on day 6, her balance = $400
on day 7, her balance = $0
on day 8, her balance = $400
From the above illustration, Ebony withdraws all the money and deposits the same amount, each every other days.
c) I do not think so, perhaps, she must have been doing that previously, between day 4 and day 8, but have changed her way of withdrawals and savings between day 8 and day 12.
Explanation:
The average balance from Day 4 to Day 8 was $400 because her balance remained the same in that period. The balance didn't change per day, making the estimated daily change $0. Jade's statement couldn't be true as withdrawing the same amount spent from Day 8 to Day 12 would result in negative balance.
The question touches on averages, and understanding bank balance trends in a period.
(a) The average daily balancefrom Day 4 to Day 8 can be determined by simply taking the balance on these days and dividing by the number of days. In this case, the balance is $400 and the number of days is 4 (Day 4 inclusive to Day 8). So her average daily balance was $400.
(b) The estimated daily balance changefrom Day 4 to Day 8 can be calculated by finding the difference between the balances on these days and dividing by the number of days. However, because her balance remained the same during this period, the change per day was $0.
(c) As for Jade's statement, it cannot be true because if the same amount was deposited from Day 0 to Day 4 to reach $400, withdrawing the same amount from Day 8 to Day 12 would not result in a $0 balance but rather in a balance of $-400, given that Ebony's balance would go into the negatives.

B. The chronological structure explains how the use of natural resources has evolved and expanded over time.
C. The problem-and-solution structure establishes how the problem came to be, describes the potential outcomes, and suggests actions for resolution.
D. The cause-and-effect structure tells how each type of natural resource is used and explains the specific effects of the resources’ usage on the environment.
Answer:
I believe the correct answer is C. The problem-and-solution structure establishes how the problem came to be, describes the potential outcomes, and suggests actions for resolution.
Explanation:
Roosevelt's famous speech about conservation does indeed refer to history - both American and the whole world's history. But it only does so in order to provide a deeper insight into the nature of the problem. He uses historic references to outline the problem (exhaustion of resources). Then, he proposes solutions to this problem.
True, America's natural resources were a great driver of economic and national growth. However, according to Roosevelt, if Americans don't adopt a new perspective and start thinking about their posterity, soon there won't be much left to work with. There are two categories of resources, each of which require a separate course of action:
The number of barrettes that Ritaleft after she gave 5 barrettes to Zoewill be 28.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Rita had 24 more barrettes than Zoe. after she gave 5 barrettes to Zoe, Rita had twice as many barrettes as Zoe.
Let 'x' be the number of barrettes that Rita has and 'y' be the number of barrettes that Zoe has. Then the equations are given as,
x = y + 24 ....1
(x - 5) = 2(y + 5)
x - 5 = 2y + 10
x = 2y + 15 ....2
From equations 1 and 2, then we have
2y + 15 = y + 24
2y - y = 24 - 15
y = 9
Then the value of 'x' is given as,
x = 9 + 24
x = 33
The number of barrettes that Rita left is given as,
⇒ 33 - 5
⇒ 28
The number of barrettes that Ritaleft will be 28.
More about the solution of the equation link is given below.

Zoe originally had 9 barettes.
Rita originally had 33 barettes.
Zoe then had 14 barettes.
Rita then had 28 barettes.
28/2=14
A because it is the only one that makes sense.
A. cause and effect
Is indeed Correct!
