Answer:
D. 9%
Step-by-step explanation:
1.04 / 2 = 0.52
2.52 / 4 = 0.63 best 1
4.32 / 8 = 0.54
9.12 / 16 = 0.57 best 2
if base on the best deal 1 - 0.63
(0.63 - 0.57) / 0.63 = 0.0952 (≈ 0.09 i.e 9%)
<u>Answer</u>
18 and 12
<u>Explanation</u>
Factor is a number or algebraic expression that divides another number or expression evenly that is with no remainder.
Odd number have few factors so the can't be the answer.
WE are going to try the even numbers.
18 ⇒ 18, 9, 6, 3, 2, 1
16 ⇒ 16, 8, 4, 2, 1
12 ⇒ 12, 6, 4, 3, 2, 1
10 ⇒ 10, 5, 2, 1
Other number less than 10 has factors less than 5.
It can be seen from above that 18 and 12 have the most factors.
(a) Data with the eight day's measurement.
Raw data: [60,58,64,64,68,50,57,82],
Sorted data: [50,57,58,60,64,64,68,82]
Sample size = 8 (even)
mean = 62.875
median = (60+64)/2 = 62
1st quartile = (57+58)/2 = 57.5
3rd quartile = (64+68)/2 = 66
IQR = 66 - 57.5 = 8.5
(b) Data without the eight day's measurement.
Raw data: [60,58,64,64,68,50,57]
Sorted data: [50,57,58,60,64,64,68]
Sample size = 7 (odd)
mean = 60.143
median = 60
1st quartile = 57
3rd quartile = 64
IQR = 64 -57 = 7
Answers:
1. The average is the same with or without the 8th day's data. FALSE
2. The median is the same with or without the 8th day's data. FALSE
3. The IQR decreases when the 8th day is included. FALSE
4. The IQR increases when the 8th day is included. TRUE
5. The median is higher when the 8th day is included. TRUE
Y=17 is not a linear function,the term refers to two distinct but similar notions
