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.

find an equation of the line passing through the point (5 4) and parallel to the line whose equation is y= 2x-6
yKpoI14uk [10]

Answer:

y = 2x - 6

Step-by-step explanation:

Given

Equation: y = 2x - 6

Required

Determine the equation of Point: (5,4)

First, we need to determine the slope of y = 2x - 6

The general form of an equation is y = mx + b

Where m represents the slope;

Hence; m =2

Since the equation and the point are parallel. then they have the same slope (m).

m = 2

Next, is to determine the equation of the point, using the following formula:

m = \frac{y - y_1}{x - x_1}

Where

(x_1,y_1) = (5,4)

So, the equation becomes

2 = \frac{y - 4}{x - 5}

Cross Multiply

y - 4 = 2(x - 5)

Open Bracket

y - 4 = 2x - 10

Make y the subject of formula

y = 2x - 10 + 4

y = 2x - 6

Hence, the equation is y = 2x - 6
