(b) What is the probability of no deaths in a corps over 7 years?

Round your answers to four decimal places (e.g. 98.7654).

Answer:

**Answer:**

(a) The probability of more than one death in a corps in a year is **0.1252**.

(b) The probability of no deaths in a corps over 7 years is **0.0130**.

**Step-by-step explanation:**

Let *X* = number of soldiers killed by horse kicks in 1 year.

The random variable .

The probability function of a Poisson distribution is:

(**a**)

Compute the probability of more than one death in a corps in a year as follows:

P (X > 1) = 1 - P (X ≤ 1)

= 1 - P (X = 0) - P (X = 1)

Thus, the probability of more than one death in a corps in a year is **0.1252**.

(**b**)

The average deaths over 7 year period is:

Compute the probability of no deaths in a corps over 7 years as follows:

Thus, the probability of no deaths in a corps over 7 years is **0.0130**.

Polygraph lie-detector machines are commonly used in criminal investigations. The device measures nervous excitement, operating on the idea that if a person is telling the truth they will remain calm. The American Polygraph Association claims that polygraphs accurately identify liars 90% of the time. In other words, if a person lied the test results will be positive 90% of the time. Although the polygraph test is good at identifying liars, there is a 50% chance that the polygraph test will say a truthful person is lying. A police force wants to predict the accuracy of lie-detector tests for 1,000 suspected criminals. Assume that 700 per 1,000 suspected criminals tell the truth during polygraph tests.

function f(x) = 2x + 20. How much money will Richard pay this month if he rents 5 video

games?

**Answer:**

Richard will pay $30.

**Step-by-step explanation:**

Because "x" is equivalent to the amount of video games he rents, you would replace "x" with 5. Do the math, and you would get 10+20=30! Hope this helps!

he will pay $30 this month

Answer: 16^2 + 12^2

Step-by-step explanation:

20^2 = 400

16 x 16 = 256

12 x 12 = 144

256 + 144 = 400

**Answer:**

(-4)-2/7=-30/7

**Step-by-step explanation:**

**Answer:**

**B -3.**

**Step-by-step explanation:**

The slope = (y2-y1)/(x2-x1)

= (-2-4)/(8-6)

= -6/2

= -3.

The sequence is alternatingly decreasing and increasing.

3 - 9 = -6

-6 + 18 = 12

12 - 8 = 4

4 + 16 = 20

Therefore, next term will be:

20 - 7 = 13

3 - 9 = -6

-6 + 18 = 12

12 - 8 = 4

4 + 16 = 20

Therefore, next term will be:

20 - 7 = 13
