Today the price of a new cell phone is $129 in 2000 the price of a similar cell phone was $240 what is the percent of the change

netineya [11]

Answer:

46.25% is the percent of the change in the price of a cell phone from 2000 to today.

Step-by-step explanation:

Cost of a cell phone in the year of 2000. C= $240

Cost of a same cell phone today, C'= $129

The percent of the change in price:

$\frac{C-C'}{C}\times 100$ :

$\frac{\$240-\$129}{\$240}\times 100=46.25\%$

46.25% is the percentage of the change in the price of a cell phone from 2000 to today.

Use the counting principle to determine the number of elements in the sample space. The possible ways to complete a multiple-cho

nadezda [96]

Answer:

The correct answer is 4294967296 possible ways to complete such a test.

Step-by-step explanation:

Step 1

The first step is to define the fundamental principle of counting. The fundamental principle of counting states that if a process can be carried out in n steps, where there are $n_1$ ways to complete the first step, $n_2$ ways to complete the second step, $n_3$ , and $n_k$ ways to complete the $k^{th}$ step, this process can be carried out in $n_1\times n_2\times n_3\times ...\times n_k$ ways.

Step 2

We use the fundamental principle of counting with $n=4$ for a total of $k=16$ steps. This test can be carried out in $4^{16}=4294967296$ ways. This comes from multiplying 4 by itself 16 times.
