The question seems incomplete, but if you are trying to figure out how much each dress costs, The answer would be $30.


To find the answer all you need to do is;
1. Subtract the price of the jeans ($40) From the total price.
160-40=120

2. Now we know the total price of the Dresses, and we also know she bought 4 of them, this means we can divide the total price ($120) of dresses, by the number (4) of dresses bought.
120/4 = 30.

So therefor, each dress costs $30 Dollars.

Hope this Helps! - Giz

alina1380 [7]

Answer:

250 is the initial value and 1.085 is the growth factor.

Step-by-step explanation:

A rare coin's value can be modeled with the equation

W(x) = 250(1.085)^{x} ................. (1)

where x represents the number of years since the coin was first purchased and W(x) is the current worth of the coin.

Now, this equation (1) is an exponential growth function.

Here, 250 is the initial value as we get W(x = 0) = 250 and 1.085 is known as the growth factor which can not be equal to 1. (Answer)

ra1l [238]

Answer: (103.3515,\ 112.6485)

Step-by-step explanation:

According to the given information, we have

n= 40

\sigma=15\\\\\overline{x}=108

Critical z-value for 95% confidence = z_{\alpha/2}=1.96

Confidence interval :

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=108\pm (1.96)\dfrac{15}{\sqrt{40}}\\\\\approx108\pm4.6485\\\\= (108-4.6485,\ 108+4.6485)\\\\=(103.3515,\ 112.6485)

Hence, the 95 percent confidence interval for this result : (103.3515,\ 112.6485)
