If you borrow $675 for six years at a interest rate of 10% how much interest will you pay
murzikaleks [220]

Answer:

the answer is $40.5

Step-by-step explanation:

the basic formula of finding our interest is I = PxRxT

P (principal) = 675

R (rate) = 10%  (we have to turn it into a decimal which is 0.010)

T (time) = 6 years

so :

I = 675 x 0.010 x 6

I = 40.5

A tennis racket at at sport city costs $180 and is discounted 15% the same model racket costs$200 at tennis world and is on sale
MaRussiya [10]
Mate, stop repeating questions, wait until your question has been answered.


15% of 180 is (180 * 0.15) = 27.

180 - 27 = $153 paid.


20% of 200 = (200 * 0.2) = 40.

200 - 40 = $160 paid.


Therefore Sport City offered the better deal.

If we wanted to create a new 90% confidence interval from a different sample for the proportion of those with a two on one date
slava [35]

Answer: 271

Step-by-step explanation:

The formula we use to find the sample size is given by :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

, where z_{\alpha/2} is the two-tailed z-value for significance level of (\alpha)

p = prior estimation of the proportion

E = Margin of error.

If prior estimation of the proportion is unknown, then we take p= 0.5 , the formula becomes

n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2

n=0.25(\dfrac{z_{\alpha/2}}{E})^2

Given :   Margin of error : E= 0.05

Confidence level = 90%

Significance level \alpha=1-0.90=0.10

Using z-value table , Two-tailed z-value for significance level of 0.10

z_{\alpha/2}=1.645

Then, the required sample size would be :

n=0.25(\dfrac{1.645}{0.05})^2

Simplify,

n=270.6025\approx271

Hence, the required minimum sample size =271
