\large\bold{\underline{\underline{  \: x = 5  \frac{2}{3}   }}}

\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}

3x - 4 = 13

➺ \: 3x = 13 + 4

➺ \: 3x = 17

➺ \: x =  \frac{ 17}{3}

➺ \: x = 5  \frac{2}{3}

\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}

➺ \: 3x - 4 = 13

➺ \: 3 \times 5 \frac{2}{3}   - 4 = 13

➺ \: 3 \times  \frac{17}{3}  - 4 = 13

➺ \: 17 - 4 = 13

➺ \: 13 = 13

➺ L. H. S. = R. H. S.

Hence verified.

In a network of 30 computers, 4 have a copy of a particularly critical file to sustain an organization's regular operations. Sup
posledela

The probability that all 4 computers with the critical file fail in this incident

P(x=4)=0.00085

This is further explained below.

<h3>What is the probability that all 4 computers with the critical file fail in this incident? </h3>

Generally,  is  mathematically given as

$H \rightarrow(n, m)$

p.d.F. of Hyper Geometric distribution

given, $N=39, n=4, M=8, x=4$

\begin{aligned}P(x=4) &=\frac{8}{4} \frac{39}{39} \\&=\frac{70 \times 1}{82251}\end{aligned}$$

\begin{aligned}&P(x=4)=8.5106 \times 10^{-4} \\&P(x=4)=0.00085\end{aligned}

In conclusion, P(x=4)=0.00085

Multiply(4×10^4)(3.63×10^-4) in scientifc notation
soldier1979 [14.2K]
Rewrite 
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0 

14.52

Hope this helps :)

assume the substance has a half-life of 11 years and the initial amount is 126 grams.How long will it be until only 15 % remains
Mumz [18]
(126) times (1/2 to the x/11 power) = 15% times 126

(1/2) to the x/11 power = 0.15

Take the log of both sides :

(x/11) times log(1/2) = log(0.15)

Multiply both sides by 11 :

'x' times log(1/2) = 11 x log(0.15)

Divide both sides by " log(1/2) " :

x = 11 x log(0.15)/log(1/2) = <em><u>30.107 years</u></em> (rounded)

That's the time it takes for <em><u>any-size</u></em> sample of this substance
to decay to 15% of its original size.
