Solution:
Yes , what mathematics say that every real number has at least two factors apart from number 1 and -1.
The number zero has infinite factors.
The number 1 and -1 which is neither prime nor composite has only 1 factor i.e itself.
Prime integers has only two factors one and itself.
Non prime integers has more than two factors.
But when you say a number apart from natural, whole and integers it includes rational ,and irrational and when we combine them The set is called Real number. .So, Yes this statement is true for rational and irrational also.
So, yes Kia is not absolutely true, but if she has written the statement in this form: Apart from 1 and -1 , every number has at least two factors then it would have been a true statement.

Answer:
x = 5
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other. This means ...
PQ = PS
2x +15 = 5x
15 = 3x . . . . . . subtract 2x
5 = x . . . . . . . divide by 3
B) negative. Is the answer
Answer:
2) 11
3) 21
4) 7
Step-by-step explanation:
2) (-6) -(-17) = 17 - 6 = 11
3) 19 - (-2) = 19 + 2 = 21
4) (-13) + 20 = 20 - 13 = 7
Answer:
b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.
Step-by-step explanation:
Confidence interval:
Confidence level of x%
We build from a sample.
Between a and b.
Intepretation: We are x% sure that the population mean is between a and b.
In this question:
90%
45 CEO's
Between ($139,048, $154,144).
So
We are 90% sure that the mean salary of all CEO's falls within this interval.
The correct answer is:
b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.
