Answer:

15.69% decrease

Step-by-step explanation:

To find the percent change, we take the original price and subtract the new price

2.55 -2.15 = .40

Divide by the original price

.40/2.55

.156862745

Multiply by 100%

15.6862745 %

Since the price went down, this is a decrease

15.69% decrease

Use the row of numbers shown below to generate 12 random numbers between 01 and 99. 11097, 51877, 41665, 78465, 79932, 54899, 72
Nikolay [14]

The suitable numbers are:

11  09  75  18  77  41  66  57  84  65  79  93

Step-by-step explanation:

The random number line is used to generate random numbers between the given range

As the numbers have to be chosen  between 01 to 99, two digit pairs will be made.

Every time a pair is chosen, it is checked whether it falls in the range or not. If it falls in the range, it is selected otherwise the number is ignored.

So,

Given random number line is:

11097, 51877, 41665, 78465, 79932, 54899, 72970, 71789

The pairs will be:

11  09  75  18  77  41  66  57  84  65  79  93  25  48  99  72  97  07  17 89

Hence,

The suitable numbers are:

11  09  75  18  77  41  66  57  84  65  79  93
