A bank says you can do or your money in 10 years if you put 1000 in in a simple interest account.What annual interest rate does
devlian [24]

Answer:

r=10\%

Step-by-step explanation:

<u><em>The correct question is</em></u>

A bank says you can double your money in 10 years if you put $1,000 in a simple interest account. What annual interest rate does the bank pay?

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=10\ years\\ P=\$1,000\\ A=\$2,000\\r=?

substitute in the formula above

2,000=1,000(1+10r)

Solve for r

Divide by 1,000 both sides

2=1+10r

Subtract 1 both sides

10r=2-1

10r=1

Divide by 10 both sides

r=1/10

r=0.10

Convert to percentage (multiply by 100)

r=0.10*100=10\%

The equation for the line of best fit is f(x) ≠1. 8x ⒠5. 4 for the set of values in the table. A 2-column table with 7 rows.
AleksandrR [38]

The equation for the line of best fit, the good approximation for x when f(x) = 30 is 20.

Given that

The equation for the line of best fit is f(x) = 1.8x − 5.4 for the set of values in the table.

A 2-column table with 7 rows.

The first column is labeled x with entries 4, 5, 6, 6, 8, 9, 10.

The second column is labeled f(x) with entries 5, 2, 5, 6, 8, 7, 18.

We have to determine

Using the equation for the line of best fit, what is a good approximation for x when f(x) = 30?

According to the question

The quadratic regression equation can be expressed as;

\rm f(x) = 1.8x - 5.4

Then,

The approximation for x when f(x) = 30 is,

\rm f(x) = 1.8x - 5.4\\\\\rm 30= 1.8x - 5.4 \\\\ 1.8x= 30+5.4\\\\1.8x=35.4\\\\x = \dfrac{35.4}{1.4}\\\\x=19.67\\\\x=20 \ approx

Hence, the equation for the line of best fit, the good approximation for x when f(x) = 30 is 20.
