Construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDLcholesterol?

sample mean = x-bar = 4.7
ME = 1.96*15.6/sqrt(43) = 4.663

95% CI: 4.7 - 4.663 < u < 4.7 + 4.663

What is X when 19,695 divided by X-15,605 = 100

Zepler [3.9K]

Step-by-step explanation:

$\frac{19695}{x - 15605} = 100$

$19695 = 100(x - 15605)$

$19695 = 100x - 1560500$

$19695 + 1560500 = 100x$

$15801 95 = 100x$

$\frac{1580195}{100} = x$

$x = 15801.95$

Felipe borrowed $8000 at a rate of 16.5%, compounded monthly. Assuming he makes no payments, how much will he owe after 7 years?

Gelneren [198K]

Answer:

$25,193.17

Explanation:

Given:

• Principal Felipe borrowed, P=$8000

• Annual Interest Rate, r=16.5%=0.165

• Compounding Period, k=12 (Monthly)

• Time, t=7 years

We want to determine how much he will owe after 7 years.

In order to carry out this calculation, use the compound interest formula below:

$A(t)=P\mleft(1+\frac{r}{k}\mright)^{tk}$

Substitute the values defined above:

$A(t)=8000\mleft(1+\frac{0.165}{12}\mright)^{12\times7}$

Finally, simplify and round to the nearest cent.

$\begin{gathered} A(t)=8000(1+0.01375)^{84} \\ =8000(1.01375)^{84} \\ =\$25,193.17 \end{gathered}$

After 7 years, Felipe will owe $25,193.17.
