Answer:

option B  and C

Step-by-step explanation:

Lets check each function

 Lets simplify \frac{x^2-25}{x+5}

factor the numerator

x^2-25 = (x+5)(x-5)

\frac{(x+5)(x-5}{x+5}

Cancel out x+5  so we are left with x-5

When x=-5  then f(x) = x-5= -5-5 = -10

To make the function continuous at x=-5  the value of f(x) should be -10

So option B is correct

Now we check with option C  and D

Lets simplify \frac{x^2+10x+25}{x+5}

factor the numerator

x^2+10x+25 = (x+5)(x+5)

\frac{(x+5)(x-5}{x+5}

Cancel out x+5 , so we are left with x+5

When x=-5  then f(x) = x+5= -5+5 = 0

To make the function continuous at x=-5  the value of f(x) should be 0

So option C is correct

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
