Answer:
A change from 600 to 780 represents a positive change (increase) of 30%
Since they are consecutive, we can define the two unknowns with ease.
The left page (has a smaller value) can be defined as X, and the right page can be defined as X+1.
So,
X + (X+1) = 293
2x+1 = 293
2x = 292
x = 146
So, as we defined before, the smaller page number is equal to x. Therefore, the smaller page number is 146, and the larger page number is 147.
Answer:
a) Least (V):69 Greatest (V):84
b) 74 78 79 82 84 are equally the higher frequency so we go with the lower value (V): 74 which is also the mode and modal.

Answer:
1320
Step-by-step explanation:
There are three "spots" for balls.
__ __ __
For the first "spot," and without replacement, meaning we don't put the balls back, there are 12 choices.
12 __ __
But for the next spot, there are only 11 choices. And for the next, there are only 10!
12 11 10
Since these are independent events, we multiply them together.
12 x 11 x 10 = 1320
There are 1320 possibilities!
How could we do it on the calculator, much faster? The question says "in order," so we know it's a <em>permutation,</em> not a <em>combination.</em> This is the nPr button on the calculator (math -> prb -> 2). Just type in 12 nPr 3 and you get the same answer, 1320.
