Which statement about the data is true?
A. The median is 4, and the interquartile range is 10
B. The median is 4, and the interquartile range is 5
C. The median is 5, and the interquartile range is 10
D. The median is 5, and the interquartile range is 5
Answers
Answer:
Letter B is the correct answer. Median is 4 and IQR is 5.
Step-by-step explanation:
The median is 4 and the interquartile range is 6. The correct option is B.
What is an interquartile range?The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.
The median is the middlemost value of the numbers arranged in ascending orders. If the number of the data is an odd number so the median will be a middle number if the number of the data is even then the median is the mean of the middle two numbers.
The data is given below:-
0,0,0,1,1,3,3,3,4,4,4,6,6,7,7,7,8,8,9,10
Median = (4 + 4) / 2 = 4
The interquartile range is calculated as:-
0,0,0,1,1,3,3,3,4, | 4,4 |, 6,6,7,7,7,8,8,9,10
Lower range upper range
IQR = 7 - 1 = 6
Therefore, the median is 4 and the interquartile range is 6. The correct option is B.
The complete options are given below:-
A. The median is 4, and the interquartile range is 5
B. The median is 4, and the interquartile range is 6
C. The median is 5, and the interquartile range is 6
D. The median is 5, and the interquartile range is 5

True or false:a. If the proportion of defectives in the sample is less than 12%, it is reasonable to conclude that the new process is better.b. If the proportion of defectives in the sample is only slightly less than 12%, the difference could well be due entirely to sampling variation, and it is not reasonable to conclude that the new process is better.c. If the proportion of defectives in the sample is a lot less than 12%, it is very unlikely that the difference is due entirely to sampling variation, so it is reasonable to conclude that the new process is better.
Answers
Answer:
false
Step-by-step explanation:
In a population, the percentage or fraction which is not conforming to (defeating) is defined as a ratio of the population's figures of non-conforming goods to the sum of goods in the inhabitants, and the further discussion can be defined as follows:
In option A, it is wrong because the proportion of both the sample is simply an approximation. The real percentage could be more than 12%. Furthermore, the conclusion also that the new procedure is better cannot be reasonably concluded.In options (b and c) both are correct because it is based on the explanation of whether, if the fraction of defective differences is bigger, we can only determine that its new procedure is better or not as a minor difference may occur from the variance of samples.Learn more:

Answer:
B. f(x) = x² + 10x + 17
Step-by-step explanation:
Given:
f(x) = (x + 5)² - 8
Required:
Write in standard form
SOLUTION:
f(x) = (x + 5)² - 8
Expand (x + 5)²
f(x) = (x + 5)(x + 5) - 8
f(x) = x(x + 5) +5(x + 5) - 8
f(x) = x² + 5x + 5x + 25 - 8
Add like terms
f(x) = x² + 10x + 17

a) How much-water will be in the water storage facility
in 25 minutes?
B.) write an equation to find the number of gallons,y,in the storage facility after x minutes.
Answers
Answer: See explanation
Step-by-step explanation:
a) How much-water will be in the water storage facility in 25 minutes?
Since the city water workers begin filling it at a rate of 500 gallons per minute, in 25 minutes they'll have filled:
= 500 × 25
= 12500 gallons
It immediately begins sending some of its water into the city's water pipes at a rate of 150 gallons per minutes. In 25 minutes, they'll have sent:
= 150 × 25
= 3750 gallons
Amount that'll be left in the tank will be:
= 12500 - 3750
= 8750 gallons
b. Write an equation to find the number of gallons,y,in the storage facility after x minutes. This will be:
y = (500 × x ) - (150 × x)
y = 500x - 150x
y = 350x

Find the series:0,2,6,12,20and.......?
Answers
Answer:
The series is represented by sum [tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex]. The remaining element of the series is 30.
Step-by-step explanation:
This exercise consist in deriving the function which contains every element of the given series. The sum that contains all elements of the series { 0, 2, 6, 12, 20,...} is represented by the following formula:
[tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex] (1)
Where [tex]n[/tex] is the cardinal associated with the element of the series.
Lastly, we proceed to evaluate the sum for the first five elements:
n = 0
[tex]f(0) = 0[/tex]
n = 1
[tex]f(1) = 0 +2[/tex]
[tex]f(1) = 2[/tex]
n = 2
[tex]f(2) = 0 + 2 + 4[/tex]
[tex]f(2) = 6[/tex]
n = 3
[tex]f(3) = 0 + 2 + 4 + 6[/tex]
[tex]f(3) = 12[/tex]
n = 4
[tex]f(4) = 0+2+4+6+8[/tex]
[tex]f(4) = 20[/tex]
The series is represented by sum [tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex].
Lastly, the missing element is found by evaluating the function at [tex]n = 5[/tex], that is:
n = 5
[tex]f(5) = 0 + 2 + 4 + 6 + 8 + 10[/tex]
[tex]f(5) = 30[/tex]
The remaining element of the series is 30.

What is fraction?fraction, In arithmetic, a number expressed as a quotient, in which a numerator is divided by a denominator.
In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
If we divide 1/3 by 2, which is not possible
Fraction also multiplication only.
To make the division into multiplication we have to reciprocal the number on the right side of the division
So,
1/3÷2
=1/3*1/2
= 1/6
Hence, 1/3 divided by 2 in fraction form gives 1/6.
