points scored and High represents the highest points scored by a single
team member.

PART A:
The range, the IQR (inter-quartile range) and the standard deviations are measures which are used to measure the spread of a data set.
A dataset is more consistent relative to another data set when the standard deviation is less than that of the other data set.
From the table, it can be seen that Team C has the least standard deviation.
Therefore, </span><span>If
the club wants to award the team that has the most consistent scoring
among its team members,
team C should be chosen.
PART B
The mean and the median is a measure of center of a data set.
The mean describes the average of a data set.
From the table, it can be seen that Team B has the highest average score.
Therefore, </span><span>If the club wants to award the team with the highest average score,
team B should be chosen.</span>
Printing Press 1: 6000/20 minutes which is 300/minute
Printing Press 2: 15000/60 minutes which is 250/minute
The faster press (the first one) would print 50 more copies per minute than the slower one (the second one).
4)
x + 5 < 14
Subtract 5 on both sides
x + 5 - 5 < 14 - 5
x < 14 - 5
x < 9
Answer is D.
5)
< (less than) and > (greater than) have empty circles because the number is not included.
For example, x > 5
5 is not a solution because we are looking for all x that is greater than 5.
≤ (less than or equal to) and ≥ (greater than or equal to) have a closed circle because the number is included.
For example, x ≤ 7
7 is a solution because we are looking for all x that is less than or equal to 7.
Answer is C.
6)
4(x-1) ≥ 8
Divide 4 on both sides
(x-1) ≥ 2
Add 1 on both sides
x ≥ 3
Answer is D.
Answer:
its not a whole number
2020 divided by 44 in decimal = 45.90
2020 divided by 44 in fraction = 2020/44
2020 divided by 44 in percentage = 4590.90909091%
