The quality of computer disks is measured by sending the disks through a certifier which counts the number of missing pulses. A

certain brand of computer disks averages 0.1 missing pulse per disk. Let the random variable X denote the number of missing pulses. Find the probability distribution of X.

Answer:

Poisson distribution.

Step-by-step explanation:

We have the mean number of missing pulses per disk, which means that the distribution for X, the number of missing pulses, will be the Poisson distribution.

It is not the binomial distribution because we are not given the probability of a missing pulse on a disk, but the mean number of missing pulses.

John wrote the numbers 678,901 and 67,890. How many times greater is the value of 7 in 678,901?​
worty [1.4K]

Answer:

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890

Step-by-step explanation:

step 1

we have

678,901

Write in expanded form

678,901=600,000+70,000+8,000+900+1

The value of 7 is 70,000

step 2

we have

67,890

Write in expanded form

67,890=60,000+7,000+800+90

The value of 7 is 7,000

step 3

Divide 70,000 by 7,000

\frac{70,000}{7,000}=10

therefore

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890

Given ABC with A(0, 0), B(2, 3),<br> and C(4,0), prove ABC is isosceles
Likurg_2 [28]

Step-by-step explanation:

1. if to calculate the length of AB; AC and BC, then:

|AB|=\sqrt{(2-0)^2+(3-0)^2} =\sqrt{13}.

|AC|=\sqrt{(4-0)^2+(0-0)^2} =4.

|BC|=\sqrt{(2-4)^2+(0-3)^2}= \sqrt{13}.

2. if to compare the calculated lengths, then:

AB=BC. It means the given triangle is isosceles.

PT=7x-24 and TQ=6x-2, Find PT.
KengaRu [80]
Though we cannot exactly find PT, we can find it in terms of TQ. Multiply the second equation by 7/6 to get 7TQ/6=7x-7/3. Subtracting 65/3 from both sides, we get 7TQ/6-65/3=7x-24. Since the right side is equal to PT, PT=7TQ/6-65/3.
