Answer: $8 flat rate
Step-by-step explanation: First subtract 24.50 from 48.50 to find the amount that was charged for the 3 additional books.
48.50 - 24.50 = 24
So the remaining 3 books costed a total of $24
Next, we need to divide 24 by 3 to determine how much each additional book costs.
24/3 = 8
So, the flat rate after the first book is purchased is $8 per additional book.
Answer:
0.141
Step-by-step explanation:
There are ₇C₁ ways to choose 1 woman from 7.
There are ₅C₃ ways to choose 3 men from 5.
There are ₁₂C₄ ways to choose 4 people from 12.
So the probability is:
₇C₁ ₅C₃ / ₁₂C₄
7 × 10 / 495
0.141
Answer:
- y = 1.8x +53.7
- 73.5 in 2005
Step-by-step explanation:
The 2-point form of the equation of a line is useful here. It tells you that for the points (x1, y1) and (x2, y2) the line can be written as ...
y = (y2 -y1)/(x2 -x1)(x -x1) + y1
For your given points, this is ...
y = (60.9 -57.3)/(4 -2)(x -2) +57.3
y = 1.8(x -2) +57.3
y = 1.8x +53.7 . . . . . simplify
__
For x = 11 (in 2005), the predicted value is ...
y = 1.8·11 +53.7
y = 73.5
