Answer:

a)[tex]1.3887943865 \times 10^{-11}[/tex]

b)P(X>5)=1

Step-by-step explanation:

[tex]P(X=x)=\frac{e^{-\lambda} \lambda^k}{k!}[/tex]

We are given that Messages arrive at a computer at an average rate of 25 messages per second.

[tex]\lambda = 25[/tex]

a) Find the probability that no message arrive in 1 second.

[tex]P(X=0)=\frac{e^{-25} (25)^0}{0!}\\P(X=0)=\frac{e^{-25} (25)^0}{0!}\\P(X=0)=1.3887943865 \times 10^{-11}[/tex]

b) Find the probability that more than 5 messages arrive in a 10-second period.

[tex]P(X>5)=1-P(X \leq 5)[/tex]

[tex]P(X>5)=1-\sum_{0}^{10} (P(X=0)+P(X=1)+........+P(X=5))[/tex]

P(X>5)=1

Answer:

399/500

Step-by-step explanation:

the reason for this is because the area of the devision "1000 randomly selected flights of a major airline showed that 798 of the flights arrived on time" means that this is divided into places to make a full example

The probability of event of a flight arriving on time will be -

P(A) = 399/500.

Probability is the extent to which an event is likely to occur and is measured by the ratio of the favorable cases to the total number of cases possible.

Given is a study of 1000 randomly selected flights of a major airline which showed that 798 of the flights arrived on time.

Let event A represents the arrival of flight on time.

Total number of favorable cases = 798

Total number of possible cases = 1000

Then the probability of event A will be -

P(A) = 798/1000 = 399/500

Therefore, the probability of event of a flight arriving on time will be -

P(A) = 399/500

Answer:

Option (B)

Step-by-step explanation:

Properties of a rational number:

1). A decimal number which has the repeating numbers after decimal is a rational number.

Example: 2.134134134......

Here 134 is repeating after decimal so the number is a rational number.

2). A decimal number which can be written as a fraction is a rational number.

Example: 0.25 = [tex]\frac{1}{4}[/tex]

Here 0.25 can be written as a fraction [tex]\frac{1}{4}[/tex] therefore, its a rational number.

In the given options,

Option A

No repeating numbers in first number therefore its an irrational numbers.

Option B

0.684 = [tex]\frac{171}{250}[/tex]

Option C

First number is an irrational number.

Option D

First number is an irrational number.

Therefore, Option (B) is the answer.

Answer: The maximum height of the ball was 2.5 seconds after it was thrown.

Step-by-step explanation:

As shown in the table, the ball started coming down after the third second and yet the height at both the second and third seconds were the same. This means that the ball hit its highest extent between the second and third seconds.

Taking an average of these digits will give;

= (2 + 3) / 2

= 2.5 seconds

The ball therefore hit its highest level at 2.5 seconds and then started its descent.

Step-by-step explanation:

slope in this case is 2/3

this equation is in slope intercept form

y=mx+b

m is slope

and b is y-intercept

so

m =2/3

b=-4

Answer: The slope is 2/3 (0.666...)

Step-by-step explanation: The slope is the coefficient of X in slope-intercept form. y=2/3x-4 is in slope-intercept form (y=mx+b) m = slope, b = y-intercept (the Y value when the X is equal to 0)

Answer:

The answer is below

Step-by-step explanation:

The number of vacation days taken by employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days. For the next employee, what is the probability that the number of days of vacation taken is less than 10 days? More than 21 days?

Answer: Z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. It is given by the equation:

[tex]z=\frac{x-\mu}{\sigma}\\ \\x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]

Given that: μ = 14, σ = 3

a) For x < 10

[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{10-14}{3}=-1.33[/tex]

From the normal distribution table, P(x < 10) = P(z < -1.33) = 0.0918

b) For x > 21

[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{21-14}{3}=2.33[/tex]

From the normal distribution table, P(x > 21) = P(z > 2.33) = 1- P(z < 2.33) = 1 - 0.9901 = 0.0099

Answer:

x = 21

Isolate the variable by dividing each side by factors that don't contain the variable.

The function that Annie can use to calculate both price changes is f(p) = 1.85p+10. Therefore, option A is the correct answer.

Given that, a discount function on each price, d(p)=0.85p and then increase the resulting price is r(p)=p+10.

A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.

Now, the function that Annie can use to calculate both price changes

f(p) = d(p)+r(p)

⇒ f(p) = 0.85p+(p+10)

⇒ f(p) = 1.85p+10

The function that Annie can use to calculate both price changes is f(p) = 1.85p+10. Therefore, option A is the correct answer.

Step-by-step explanation:

Answer:

[tex]a=1[/tex]

[tex]b=-1[/tex]

Step-by-step explanation:

Once [tex](x-1)^2[/tex] is a factor and [tex](x-1)^2 = (x-1)(x-1)[/tex], we have that two roots of the cubic equation are equal to 1. So,

[tex]ax^3+bx^2+1 = (x-1)(x-1)(x-d)=0[/tex]

As [tex]d[/tex] the unknown root.

Expanding

[tex]ax^3+bx^2+1 = (x-1)(x-1)(x-d)=0[/tex]

[tex]ax^3+bx^2+1 = (x^2-2x+1)(x-d)=0[/tex]

[tex]ax^3+bx^2+1 = x^3-2x^2+x-dx^2+2dx-d=0[/tex]

Now, comparing the two expressions, we have

[tex]ax^3+bx^2+1 = x^3+(-2-d)x^2+(1+2d)x-d=0[/tex]

Therefore, know we know

[tex]a=1[/tex]

[tex]b=-2-d[/tex]

[tex]d=-1[/tex]

So,

[tex]b=-2-(-1)=-2+1=-1[/tex]
