Partitioning means to find the dividing point between two points.
This is done by prorating the difference in x- and y-coordinates, and adding to the first.
We will take the first point (from A to B) as A(16,8).
The difference is B-A, i.e.
(1,3)-(16,8) = (-15,-5)
2/5 of the difference is (2/5)*(-15,-5) = (-6,-2)
Add the difference to the first coordinates (point A) gives
Point of division = (16,8)+(-6,-2) = (16-6, 8-2) = (10,6)
Answer:
C) 201
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
Assuming n > 30, we can approximate CV with a normal distribution. At P = 99%, CV = 2.576.
SE = σ / √n
SE = 1100 / √n
Therefore:
200 = 2.576 × 1100 / √n
n = 201
In 2008, up to 405 messages could be sent without spending more than $ 100.
Since in 2008, text messages were charged per text, and some carriers charged $59 for a basic text package of 200 texts and 20 cents per text after that, while today, most packages include unlimited text and data but cost closer to $ 100 a month, to determine the range of text messages you can send with the 2008 plan without spending more than $100, the following calculation must be performed:
- (41 / 0.2) + 200 = X
- 205 + 200 = X
- 405 = X
Thus, in 2008, up to 405 messages could be sent without spending more than $ 100.

Answer: d)8
Step-by-step explanation: 8 times 3 equals 24 which would be how many betty has while katie has just 8 adding it together making a total of 32
Answer:
1: 24 girls
2: 640
3: 300
4: 3/10
5: 42
Step-by-step explanation:
1: 2/5 × 40
80÷ 5
16
girls = 40- 16
= 24
2: 1/3 × 960
960 ÷3
= 320
Left = 960 - 320
= 640
3: 3/8 × 480
1440 ÷ 8
= 180.
Left = 480 - 180
= 300
4: 2/5 × 3/4
= 6/20
= 3/10
5: 2/5 × x = 18
2x = 28 × 5
2x = 140
x = 70
70 - 28
= 42
