A clothing store has a section of jeans on sale. There is a 30% chance of picking a pair with a 30-inch inseam; a 25% chance of

Andrej [43]

The expected value of the inseam length of the jeans is found as

30% of 30+ 25% of 32+ 10% of 34+ 10% of 36 + 10% of 38 + 15% of 40

= $\frac{30}{100}\times30 +\frac{25}{100}\times32+ \frac{10}{100}\times34+ \frac{10}{100}\times36 +\frac{10}{100}\times38+ \frac{15}{100}\times40$

= $9+8+3.4+3.6+3.8+6=33.8$

Hence, the third option 33.8 is the correct expected value.

If f(x)=2x-4, what would be the answer if f(3)-1??

Vinil7 [7]

Answer:

Step-by-step explanation:

We have the function

$f(x) = 2x - 4$

and we want to know the value of $f(3) - 1$ .

The first step is to find $f(3)$ ; we can subtract 1 from it at the end! But what does $f(3)$ mean?

Basically, we're saying "what is the value of the function when $x = 3$ ?"

So, we simply replace $x$ with 3 in the function, and we get:

$f(3) = 2\times 3 - 4 = 2$ .

Finally, we subtract 1 to find $f(3) - 1 = 1$ .
