A stock brokerage has four computers that are used for making trades on the New York Stock Exchange. The probability that a computer fails on any single day is 0.005. Failures occur independently. Any failed computers are repaired after the exchange closes, so each day can be considered an independent trial.(a) What is the probability that all four computers fail on one day?(b) What is the probability that at least one computer fails on a day?(c) What is the mean number of days until a specific computer fails?

Answers

Answer:

A) 0 , B) 0.0199 , C) 200

Step-by-step explanation:

Let X denotes no. of computers fail on day

X ~ Bin (n = 4 , p = 0.05)

A] P (X = x) = (n c x) p^x q^n-x

P (X = 4) = (4 c 4) (0.005)^4 (0.995)^0

(0.05)^4 ~ 0

B] P (X > 1) = 1 - P (X < 1) = 1 - P (X = 0)

1 - { ( 4 c 0) (0.005)^0 (0.995)^ 4 }

1 - (0.995)^ 4 ~ 0.0199

C] Let Y depict mean number of days until a specific computer fails

Y ~ Geom (p = 0.005)

Mean = E (Y) = 1/p = 1/0.05 = 200

Solve the following inequality for k. Write your answer in simplest form.4k + 2(3k + 8) <3k + 10 – 8

Answers

Answer:

k < -2

Step-by-step explanation:

Step 1: Write inequality

4k + 2(3k + 8) < 3k + 10 - 8

Step 2: Solve for k

Distribute: 4k + 6k + 16 < 3k + 10 - 8
Combine like terms: 10k + 16 < 3k + 2
Subtract 3k on both sides: 7k + 16 < 2
Subtract 16 on both sides: 7k < -14
Divide both sides by 7: k < -2

Answer:

10k+16<3k+2

10k-3k+16<2

7k<2-16

k<-2

To graph the function g(x) = (x – 5)2 – 9, shift the graph of f(x) = x2 5 units and 9 units.

Answers

Answer:

The graph of f(x) shifts 5 units right and 9 units down to graph g(x).

Step-by-step explanation:

The general form of the parabola is

$h(x)=a(x-h)^2+k$

Where, (h,k) is the vertex of the parabola and a is stretch factor.

The parent function is

$f(x)=x^2$

The vertex of the parabola is (0,0).

The given function is

$g(x)=(x-5)^2-9$

The vertex of the parabola is (5,-9).

The vertex of the parabola shifts from (0,0) to (5,-9), therefore the graph of f(x) shifts 5 units right and 9 units down to graph g(x).

To graph the function g(x) = (x – 5)2 – 9, shift the graph of f(x) = x2 ✔ right
5 units and ✔ down 9 units.
