Answer:
The correct statements are A & C.
Step-by-step explanation:
<u>Standard deviation:</u>
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
- A low standard deviation means that most of the numbers are close to the average.
- A high standard deviation means that the numbers are more spread out
Statement A is correct, City A's heights are more spread than City B's, because. City A's standard deviation is greater than City B.
Statement C is correct, because city A's mean is lesser than City B.
Answer:
He is incorrect in this statement because 38 and 40 both have factors, other than 1 x itself. Prime numbers are numbers the only have 1 factor pair, and that is 1 x itself. Factors are the numbers you multiply to get the end result, and an example is 10x4=40. The factors of 40 are 8x5, 4x10, 2x20, and of course, 1x40. The factors of 38 are 2x19, and 1x38.
