2/3(n + 9) = 12 What is N? n = _

1 answer:

4 0

N + 9 = 12 means N is a number which, when added to 9, must give the answer 12. So N can only be the number 3 because only 3 + 9 is equal to 12.

9) (-12) – 3 5-15. 10) (-2) – 5. = -7. 11) (-9)–1 = -10. 12) 3-1. = 2. 13) 10- (-3) = 13 ... n-4 = 22. 9) the product of c and 10 is 24. 10) the sum of a number and 7 is 44 ... 17) (-5)-(-9) . ” (+8)+6-7. 18 (-26) – (-5) -7. 18) (-3). (-1). 24. 19) ī. ” (-2). 3 -2. -3.

Answer:

Yes, there is one outlier (lower)

Step-by-step explanation:

Looking at the distribution of the lower/smallest observation, we can see that there is a values in the lower/smallest that is very far from others. See the attached box-plot for understanding.

The median is the line in the middle of the box-plot.

The Lower fourth is the lower whisker line and upper fourth is the upper whisker line. The lower box (just below the median) line is the 1st quartile and the upper box line (just above the median) is 3rd quartile.

Answer:

m = 3

Step-by-step explanation:

Assuming these shapes are similar, you can set up a proportion:

$\frac{8}{12} =\frac{2}{m}$

→Cross multiply:

$\frac{8m}{24}$

→Divide 24 by 8:

m = 3

Using permutations and the probability concept, it is found that there is a 0.0417 = 4.17% probability that Nia is chosen as president.

A probability is the number of desired outcomes divided by the number of total outcomes.

As there are different roles, the order in which the students are chosen is important, hence, the permutation formula is used to solve this question.

Permutation formula:

The number of possible permutations of x elements from a set of n elements is given by:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

Desired outcomes:

Nia's president.

For the other roles, 3 students from a set of 23, hence:

$D = P_{23,3} = \frac{23!}{20!} = 10626$

Total outcomes:

4 students from a set of 24, hence:

$T = P_{24,4} = \frac{24!}{20!} = 255024$

Then:

$p = \frac{D}{T} = \frac{10626}{255024} = 0.0417$

0.0417 = 4.17% probability that Nia is chosen as president.
