1-9 = 9 digits
10-99 = 180 digits
So if we continue the pattern to 99, there are 189 digits, and the last 5 digits would be 79899. Counting backwards: 189th = 9, 188th = 9, 187th = 8, 186th = 9, 185th = 7.
The 185th digit is 7.
Answer:
Cluster sampling
No
Step-by-step explanation:
Missing part of Question
Find:
a) Which type of sample is this?
b) Is it the correct choice ?
Solution:
- Simple random sample is the one in which every individual would have equal chance of being selected.
- Stratified random sample draws simple random sample from the independent sub-groups.
- Systematic sampling is letting every kth individual be in the sample ( k as an integer )
- Convenience sampling is used for example voluntary response or a sub-group from the population.
a)
Cluster sampling was used in our case because one of all the teams were chosen and this entire team is in this sample.
b)
No. This method has limitation of giving us a shortsighted view which lacks the overview on the use of performance-enhancing drugs, we can only use this sample to draw conclusions on the team.
(4, -1) ---> x = 4 and y = -1
If you look at the graph you can se this
Mark points (0, 2) and (8, -4) in the coordinate plane
Plot the line going through both of these points.
Read the coordinates of the intersection of the line so you can see the solution!
Answer: the hourly fee for the rototiller is $3
Step-by-step explanation:
Let h represent the hourly fee for renting the rototiller.
The rental company charged an initial fee of $43 with an additional fee per hour. Assuming that they rented the rototiller for x hours. This means that if they rented the rototiller for x hours, the total amount that they would pay is
43 + hx
If they paid $64 after renting the rototiller for 7 hours, the equation that models this problem would be
43 + 7h = 64
7h = 64 - 43 = 21
h = 21/7 = $3
I think the best answer would be letter B. Y= 20x and Y= 30x+120. So by calculating it through substitution you will come up to 20x = 30x+120. By simplifying the equation it will give you an answer of 12 days.
