Answer: 25

Step-by-step explanation:

From the question, we are told that a producer of electronic book readers is performing a quality check to make sure that the reader's backlight is working correctly. Then, the plant manager tests 2,000 readers on Monday and finds that 8 have defective backlights. The fraction 1/x is the experimental probability of a book reader having a defective backlight. What is the value of x?

Number of tested readers= 2000

Defective backlight = 8

Probability of having a defective backlight will be the number of defective backlight divided by the number of readers tested. This will be:

= 8/200

We reduce the nice fraction to its lowest term.

8/200 = 1/25

Therefore x will be 25

An outlier is a data value that is numerically distant from ________ of the other data points in a set of data
laila [671]

In the statement regarding outlier we have to fill "most" to complete the statement.

Given An outlier is a data value that is numerically distant from_________ of the other data points in a set of data.

We have to fill the blank. We can fill " most" in the blank.

If a number in data is more than 1.5 times the length of the box away from either of the upper and lower quartile of the distribution then that number is said to be an outlier.

There are two types of outliers: upper outliers, lower.

If any values in the data set are greater than the upper boundary then those values are the upper outliers.

If any values in the data set are less than the lower boundary then those values are called lower outliers.

Lower quartile =Q_{1}-1.5*IQR

Upper quartile=Q_{3}+1.5*IQR

Hence we have to use most in the sentence to complete it.

Which of the following algebraic expressions is not simplified?
AlladinOne [14]

Answer:

Option D. a^2+6ab-2ba

Step-by-step explanation:

Option D because we have like terms: 6ab and -2ba=-2ab, then

a^2+6ab-2ba=a^2+6ab-2ab

Simplifying on the right side of the equation adding like terms:

a^2+6ab-2ba=a^2+4ab
