The given expression is

$|y|+4-y\cdot x$

Let's replace x = 7 and y = -2.

$\begin{gathered} |-2|+4-(-2)\cdot7 \\ 2+4+14 \\ 20 \end{gathered}$ <h2>Therefore, the value of the expression is 20.</h2>

To avoid detection at customs, a traveler places 6 narcotic tablets in a bottle containing 9 vitamin tablets that are similar in

lukranit [14]

Answer: $\dfrac{26}{27}$

Step-by-step explanation:

Given : To avoid detection at customs, a traveler places 6 narcotic tablets in a bottle containing 9 vitamin tablets that are similar in appearance.

Proportion of success : $p=\dfrac{6}{9}=\dfrac{2}{3}$

Sample size taken by customs oﬃcial : n= 3

Let x be a binomial variable that represents the tablets in the bottle.

Using Binomial probability formula :-

$P(X=x)=^nC_xp^x(1-p)^{n-x}$

The probability that the traveler will be arrested for illegal possession of narcotics = $P(x\geq1)=1-P(x=0)$

$1-^3C_0(\dfrac{2}{3})^0(1-\dfrac{2}{3})^3\\\\=1-(1)(1)(\dfrac{1}{3})^3\ [\becuase ^nC_0=1]\\\\=1-\dfrac{1}{27}=\dfrac{26}{27}$

Hence, the probability that the traveler will be arrested for illegal possession of narcotics = $\dfrac{26}{27}$

Find the median of the data set below? -12/4, 18/5, -2.5, 1/5, 10

nirvana33 [79]

-12/4= -3

18/5= 3.6

-2.5= -2.5

1/5= .2

10= 10

Ordered) -12/4, -2.5, 1/5, -2.5, 10

The median is 1/5 since it's in the middle of all five numbers.

Hope I could help! :)
