A set of weights includes a 10 lb barbell and 8 pairs of weight plates. Each pairof plates weighs 20lbs. If x pairs of plates ar

Leni [432]

It is given that the weight of the barbel is given by:

$f(x)=20x+10$

It says that there are eight pair of weights so x can take values from 0 to 8 and f(x) can take the values as follows:

$\begin{gathered} x=0,f(x)=10 \\ x=1,f(x)=30 \\ x=2,f(x)=50 \\ x=3,f(x)=70 \\ x=4,f(x)=90 \\ x=5,f(x)=110 \\ x=6,f(x)=130 \\ x=7,f(x)=150 \\ x=8,f(x)=170 \end{gathered}$

So the range is:

$\mleft\lbrace10,30,50,70,90,110,130,150,170\mright\rbrace$

Option B is correct.

Answer:

11,232,000 license plates are possible.

Step-by-step explanation:

The order in which the symbols are chosen is important(ABC is a different plate than BAC), which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

3 letters from a set of 26.

3 digits from a set of 10. So

$T = P_{26,3}P_{10,3} = \frac{26!}{23!} \times \frac{10!}{7!} = 11232000$

11,232,000 license plates are possible.
