Answer:

We need to put $801.88 amount in the bank.

Step-by-step explanation:

given that

t=3 yr

Need amount $850 after 3 yr so P= $850

Interest rate=2%

We know that for simple interest

$P=A\left(1+\dfrac{rt}{100}\right)$

Where r is the Interest rate,t is the time,A is the present amount and P is principle amount after t time.

Here given that P= $850

So now putting the values

$850=A\left(1+\dfrac{2\times 3}{100}\right)$

So A=$801.88

We need to put $801.88 amount in the bank.

Calculate the fraction of this recurring decimal.

Agata [3.3K]

<h3>Answer: 76/4995</h3>

========================================================

Explanation:

x = 0.0152152...

10x = 0.152152...

10000x = 152.152...

Subtract the last two equations to find that

10000x-10x becomes 9990x on the left side
152.152... - 0.152152... becomes 152 on the right side

We're left with the equation 9990x = 152 which solves to x = 152/9990

Divide both parts of that fraction by 2 so that the fraction fully reduces to 76/4995 which is the final answer

You can use your calculator to see that 76/4995 = 0.0152152152152... which confirms the answer.

Find the determinancof the matrix Q.

stepan [7]

Using a Laplace expansion along the first column, we have

$\det Q=2\det\begin{bmatrix}2&1\\-1&6\end{bmatrix}+3\det\begin{bmatrix}3&4\\-1&6\end{bmatrix}+5\det\begin{bmatrix}3&4\\2&1\end{bmatrix}$

The determinant of a 2x2 matrix is trivial,

$\det\begin{bmatrix}a&b\\c&d\end{bmatrix}=ad-bc$

So we have

$\det Q=2\cdot13+3\cdot22+5\cdot(-5)=67$

Mais teacher gives 4 quizzes each worth 5 points after three quizzes she has the score 4, 3, and 4. What does she need to get on

skad [1K]

Answer:

Therefore, she must get 5 points from the last quiz to have a mean score of 4

Step-by-step explanation:

Mean is the average of a set of data, it is the sum of the data divided by the number of data.

To have a mean of 4 from 4 quizzes;

Let x represent the total;

mean = x/4

4 = x/4

x = 4 × 4 = 16

To have a mean of 4 he must have a total score of 16.

Let y represent her score in the last quiz;

16 = 4+3+4+y

16 = 11+y

y = 16-11 = 5

Therefore, she must get 5 points from the last quiz to have a mean score of 4
