Answer:

The answer is number 3.

Step-by-step explanation:

To get n by itslef, you have to divide -9 by both sides of the equation, however, since the -9 is in-between the two lines on the outside of it, it is therefore an absolute number. Usually when you divide both sides of an equation like this by a negative number, you would flip the less than symbol (>), but since the -9 is an absolute number, the negative does not count for anything. When you divide 63 by 9, you do not have to flip the less than symbol.

- Hope this helps.

Answer:

a. 0.6899

b. 0.1642

Step-by-step explanation:

a. Given the probability of success is 0.94 for an expert and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.94\times0.94\times0.94\times0.94\times0.94\times0.94\\\\=0.6899$

Hence, the probability of correctly identifying the 6 matches is 0.6899

b.Given the probability of success is 0.74 for a novice and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.74\times0.74\times0.74\times0.74\times0.74\times0.74\\\\=0.1642$

#Hence, the probability of correctly identifying the 6 matches is 0.1642

*I have used the sample size of 6(due to conflicting info/question size).

68 * 27 - 81 + ? = 600

tankabanditka [31]

The missing term is -1155.

Step-by-step explanation:

Given expression is

68 * 27 - 81 + ? = 600

Let the missing term be x

$68*27-81+x=600\\1836-81+x=600\\1755+x=600$

Subtracting 1755 from both sides

$1755-1755+x=600-1755\\x=-1155$

Therefore,

The missing term is -1155.
