Answer:

48%

Step-by-step explanation:

let's say the initial price of an item is $100

if you take 40% off then you pay only $60

now if you take 20% off 60 you pay $48

$48 is 48% of 100

1. Solve for w in the equation W/5 = 25<br> A.W = 5<br> B.W = 125<br> C. W = 30<br> D.W = 20
vekshin1

Answer: <em>w = 125</em>

Explanation: Since <em>w</em> is being divided by 5, to solve for <em>w</em>,

multiply both sides of the equation by 5.

On the left side, the 5's will cancel

and on the right side, 25(5) is 125.

So <em>w = 125</em>.

IgorC [24]

Answer:

16.7% of GMAT scores are 647 or higher

Step-by-step explanation:

The Empirical Rule states that 68% of the values are within 1 standard deviation of the mean(34% above, 34% below). It also considers that 50% of the values are above the mean and 50% are below the mean.

In this problem, we have that the mean \mu is 547 and that the standard deviation \sigma is 100.

a. What percentage of GMAT scores are 647 or higher?

647 is 1 standard deviation above the mean.

So, 50% of the values are below the mean. Those scores are lower than 647.

Also, there is the 34% of the values that are above the mean and are lower than 647.

So, there is a 50% + 34% = 84% percentage of GMAT scores that are 647 or lower.

The sum of the probabilities must be 100

So, the percentage of GMAT scores that are 647 or higher is 100% - 84% = 16%.

What is the oblique asymptote of the function f(x) = the quantity of x squared plus x minus 2, all over x plus 1
Korvikt [17]
Hello,

y=ax+b is the asymptote
with
$a=  \lim_{n \to \infty}  \frac{f(x)}{x}=\lim_{n \to \infty}  \dfrac{x^2+x-2}{x^2+x}=1\\\\&#10;
$b= \lim_{n \to \infty} f(x)-ax= \lim_{n \to \infty} \frac{x^2+x-2}{x+1}-x= \lim_{n \to \infty} \frac{-2}{x+1}=0  $
