certain computer virus can damage any file with probability 35%, independently of other files. Suppose this virus enters a folde

Ksivusya [100]

Answer:

0.623 is the probability that between 800 and 850 files get damaged.

Step-by-step explanation:

We are given the following information:

We treat virus can damage computer as a success.

P( virus can damage computer) = 35% = 0.35

The conditions for normal distribution are satisfied.

By normal approximation:

$\mu = np = 2400(0.35) = 840\\\sigma = \sqrt{np(1-p)} = \sqrt{2400(0.35)(1-0.35)} = $$23.36$

We have to evaluate probability that between 800 and 850 files get damaged.

$P(800 \leq x \leq 850) = P(\displaystyle\frac{800 - 840}{23.36} \leq z \leq \displaystyle\frac{850-840}{23.36}) = P(-1.712 \leq z \leq 0)\\\\= P(z \leq 0.428) - P(z < -1.712)\\= 0.666 - 0.043 = 0.623 = 62.3\%$

$P(800 \leq x \leq 850) = 62.3\%$

0.623 is the probability that between 800 and 850 files get damaged.

The semicircle is 25pi or 78.54

The rectangle is 120 (12*10)

The triangle is 24 (.5*12*4)

So the total is 222.54 (78.54+120+24)

F(x) = 3x + 5<br> g(x) = 4x? - 2<br> h(x) = x² – 3x + 1<br> Find f(x) + g(x) – h(x)

inysia [295]

Answer:

3x²+6x+2

Step-by-step explanation:

f(x)+g(x)-h(x)

=(3x+5)+(4x²-2)-(x²-3x+1)

=3x+5+4x²-2-x²+3x-1

=6x²+2+3x

=3x²+6x+2 (rearrange)
