Answer:
69.5%
Step-by-step explanation:
A feature of the normal distribution is that this is completely determined by its mean and standard deviation, therefore, if two normal curves have the same mean and standard deviation we can be sure that they are the same normal curve. Then, the probability of getting a value of the normally distributed variable between 6 and 8 is 0.695. In practice we can say that if we get a large sample of observations of the variable, then, the percentage of all possible observations of the variable that lie between 6 and 8 is 100(0.695)% = 69.5%.
Which list of values is ordered from least to greatest? A. |-6|, 0, 2, -|-5| B. -|-5|, |-4|, 2, 5 C. -9, -|-2|, 0, |9| D. |-10|,

Answer:
C
Step-by-step explanation:
A simplifies to 6, 0, 2, -5
B simplifies to -5, 4, 2, 5
C simplifies to -9, -2, 0, 9
D simplifies to 10, -4, 1, 7
Only C is ordered from least (-9) to greatest (9).
Step-by-step explanation:
it is a multiple of 21.
the highest common factor of 2 numbers is the longest combination of prime factors they have in common.
the prime factors of 21 are simply
3×7
if another number A shares this as the longest combination of prime factors, that means it contains 3×7 itself in its prime factors.
and that means this number A can only be a multiple of 3×7 (= 21), as other prime factors present would be the factor of 21.
