The amount of the tv in 3 years which depreciates at a rate of 4% per year is £708 .
Compound interest is interest calculated on the principal and the interest accrued in previous periods. It differs from simple interest where interest is not added to the principal when calculating interest for the next period. In mathematics, compound interest is usually represented by C.I.If the interest is compounded annually, then amount is given by [tex]A=P(1+\frac{r}{100} )^t[/tex] where " A " = Amount , " R " = annual interest rate , "T" = number of years , " P" is principal amount .
We have given principal amount = £800 , rate = 4% and time = 3 years .
Putting above values in equation (1) , we get
[tex]A=800(1-\frac{4}{100} )^3\\A= 800(1 -0.04)^3\\A=800(0.96)^3\\A=800\times 0.88\\A= \£707.78[/tex]
Note that the minus sign is due to depreciation .
On rounding off , amount will be £708 .

Scientists often write very large or very small numbers using exponents. How might a scientist write the number shown using exponents?
Answer:
It makes comparing magnitudes easier. It is much easier to estimating numbers easier. you can easily say that 0.0000000009 is smaller than 0.0000001 and even say but how much, and it reduces the amount of time you have to read the number, since instead of having 0s, you have the amount of 0s.

Bernite is selling candy bars for a school fundraiser. The school paid $20.00 for a box of 15 king-size candy bars and Bernite sells then for $2.00 each. What is the relationship the amount of candy sold and the amount of money earned? (Multiple answer choice)
a. The relationship is linear
b. The relationship is non-linear
c. The relationship is proportional
d. The relationship always results in a positive profit.
e. The relationship always results in a negative profit
Answer:
e. The relationship always results in a negative profit
b. The relationship is non-linear
Step-by-step explanation:
From the question above it could be found that, the relationship always result in negative profit. This is because:
To the school purchase,
Selling price of Candy bars in a box = $20.00
On the other hand,
Each Candy bar cost = $2.00
No of Candy bars in a box = 15
Total cost = $2.00 x 15 = $30.00
Loss (negative profit) = Total cost - Selling price
= $30.00 - $20.00 = $10.00
This also shows that, the relationship is non-linear because there is no direct relationship between the selling price and the expected profit that was supposed to have been earned.
Ten students are chosen from a statistics class of 22 students. Let X be the number who got an "A" in the class. Is this a binomial distribution, and if so, what is the number of trials?
Answer:
Yes, this is a Binomial distribution, and the number of trials is 10.
Step-by-step explanation:
From the given information:
We are being told that ten students are chosen from a statistics class of 22 students.
If X represents the random variable for the number of students who got an "A" in the class.
Then we have two possible outcomes;
Number of students that got an "A" = (Success)
Number of students that did not get an "A" = (Failure)
Thus, this is a Binomial distribution because it consists of two outcomes, and the number of trials is 10.

30% of 15000 = 4500
15000 - 4500 = 10500 rupees

Step 1: Simplify both sides of the equation.
11+x+13=40
(x)+(11+13)=40(Combine Like Terms)
x+24=40
x+24=40
Step 2: Subtract 24 from both sides.
x+24−24=40−24
x=16
Answer:
x = 16
Step-by-step explanation:
11 + x + 13 = 40
x + 24 = 40
x = 40 - 24
x = 16

As society advances, what changes to the percentage sales tax structure do you envision will need to be adjusted and what would be the best way to make the adjustment?
As society gets more advanced, there would need to be a change to the percentage tax structure to make it more progressive so that the rich pay more taxes.
The best way to make this adjustment is by passing laws.
How should taxes change as society advances?
As the society advances, there will be those who are richer and wealthier than others. They would need to take more care of society and the people who are not as fortunate as them because society would become more empathetic.
For this to happen, society would have to enact progressive tax rates where people who are wealthier pay more. This adjustment is best done by passing relevant taxation laws.

pamela ran 7/10 mile on Tuesday and 3/8 mile on Thursday. How much fatter did she run on Tuesday ?
Answer:
[tex]Difference = \frac{13}{40}[/tex]
Step-by-step explanation:
Given
[tex]Thursday = \frac{3}{8}\ mile[/tex]
[tex]Tuesday = \frac{7}{10}\ mile[/tex]
Required
How much farther is she on Tuesday
To do this, we simply calculate the difference between distance covered on both days.
[tex]Difference = Tuesday-Thursday[/tex]
[tex]Difference = \frac{7}{10} - \frac{3}{8}[/tex]
Take LCM
[tex]Difference = \frac{28- 15}{40}[/tex]
[tex]Difference = \frac{13}{40}[/tex]
