How long will it take to earn $1800 in interest if $6000 is invested at a 6% annual interest rate? how many years

Simora [160]

Answer:

Total interest will $1800 after 5 years.

Step-by-step explanation:

It is given that the principle amount is $6000.

Rate of interest rate is 6% per annum.

Total interest is $1800.

Formula for simple interest is

$I=\frac{P\times r\times t}{100}$

Where, P is principle, r is rate of interest in percent and t is time in years.

Substitute P=6000, r=6 and I=1800 in the above formula.

$1800=\frac{6000\times 6\times t}{100}$

$1800=\frac{36000t}{100}$

$1800=360t$

Divide both sides by 360.

$\frac{1800}{360}=t$

$5=t$

Therefore the total interest will $1800 after 5 years.

A simple random sample of size nequals40 is drawn from a population. The sample mean is found to be 103.9, and the sample stand

yan [13]

Answer:

There is enough evidence to support the claim that the population mean is greater than 100

Step-by-step explanation:

Step 1: We state the hypothesis and identify the claim

$H_0:\mu=100$ and $H_1:\mu \:>\:100$ (claim)

Step 2: Calculate the test value.

$t=\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }$

$\implies t=\frac{103.9-100}{\frac{21.9}{\sqrt{40} } }=1.1263$

Step 3: Find the P-value. The p-value obtained from a calculator is using d.f=39 and test-value 1.126 is 0.134

Step 4: We fail to reject the null hypothesis since P-value is greater that the alpha level. (0.134>0.05).

Step 5: There is enough evidence to support the claim that the population mean is greater than 100.

Alternatively: We could also calculate the critical value to obtain +1.685 for $\alpha=0.05$ and d.f=39 and compare to the test-value:

The critical value (1.685>1.126) falls in the non-rejection region. See attachment.

NB: The t- distribution must be used because the population standard deviation is not known.

Which number produces a rational number when added to 0.3?

Afina-wow [57]

Basically you need to find the answer choice that is rational. That way the sum will also be rational.

√7 is irrational as well as π and 0.5050050005...

2/4 is the only rational option.

Which algebraic expression is a polynomial with a degree of 4? 5x4 startroot 4 x endroot x5 – 6x4 14x3 x2 9x4 – x3 – startfracti

Paha777 [63]

The algebraic expression of a polynomial with a degree of 4 is 9x⁴ – x³ – x/5

<h3>How to determine the polynomial?</h3>

For a polynomial to have a degree of 4, the following must be true:

All exponents must be whole numbers
The highest exponent must be 4

Using the above highlight, the algebraic expression of a polynomial with a degree of 4 is 9x⁴ – x³ – x/5
