Tell which measure of central tendency best describes the data. Time spent on Internet (min/day): 75 38 43 120 65 48 52 A. Mean B. Median C. Mode

Answers

Answer 1

Answer:

Answer:

B. Median

Step-by-step explanation:

We have been given data about time spent on Internet (min/day). We are asked to determine the best measure of central tendency for the given data.

Data: 75, 38, 43, 120, 65, 48, 52,

We can see that our given data has a very large value outlier (120), so it will increase the mean.

There is no mode for the given data set as no value repeats.

We know that median is best measure for data set with large valued outliers because median is not affected by outliers.

Therefore, option B is the correct choice.

Answer 2

Answer:

The measure of central tendency that best describes the data is B. Median.

Which measure of central tendency best describes the data on time spent on the Internet?

Mean:

= (75 + 38 + 43 + 120 + 65 + 48 + 52) / 7

= 69.86

Median:

We arrange data in ascending order: 38, 43, 48, 52, 65, 75, 120. Since there are seven values, the median is the middle value: 52

Mode: There is no value that appears more than once in the data set.

Therefore, the measure of central tendency that best describes the data is B. Median.

Which are natural numbers, integers, rational numbers, irrational numbers and real numbers?0, 1, 1/12, 1/16, 1/20

Answers

-Natural numbers are 0+ (no negative or decimals)
-Integers are any number that is not 0 or a fractional number (# with decimals/fractions)
-irrational numbers are numbers with decimals that go on forever and that do not repeat themselves
-rational number is any number that is predictable. So negative numbers, 0 and any number above 0 and decimals that are predictable (ex: 5.2) or any repeating decimal not decimals that goes on forever bu does not repeat them self for example π-real numbers are any digit that is rational. This includes negative numbers and fraction.

so to answer your question

0: Natural number, real number, rational
1: Natural number, Integer, real number, rational
1/12: real number, rational
1/16: real number, rational
1/120: Real number, rational

-Calypso, 8th

natural numbers are counting numbers (1,2,3,4,5...), not including 0

integers are natural numbers plus their negatives and zero (-3,-2,-1,0,1,2,3..)

rational numbers can be written in form a/b where b is not equal zero, terminating and repeating decimals can be written in this form

irrational numbers cannot be written in form a/b, they are non-terminating decimals

real numbers are rational+irrational numbers, not including imaginary numbers

basially
natural numbers are in integers which are in rational numbers which are not integers and those make up real numbers

so

0 is a whole number but that wasn't listed so it is an integer, rational number and a real number

1 is a natural number, an integer, a ratioal number, and a real number

1/12 is in form a/b, so it is a rational number and a real number

1/16 is also in form a/b, so it is a rational number and a real number

1/20 is also in form a/b, so it is a rational number and a real number

Write a fraction that is a multiple of 4/5.

Answers

so if we assume that the ending fraction has to be equal to the origonal fraction then we multiply it by 1 or x/x where x=x

so 4/5 times 2/2=8/10
4/5 times 3/3=12/15
and so on

The Frostburg-Truth bus travels from Frostburg Mall through the city's center to Sojourner Truth Park. The mall is 4 miles east and 5 miles north of the city's center. Truth Park is 4 miles west and 2 miles south of the city's center. How far is it from Truth Park to the mall to the nearest tenth of a mile?

Select one:
a. 10.6 miles
b. 6.4 miles
c. 4.5 miles
d. 3 miles

Answers

the mall if 4 miles east and 5 miles north, which means that the city's center is 4 miles west and 5 miles south to the mall. Truth is 4 miles west and 2 miles south of the city's center. This means that:

The mall is 3 miles south of where Truth is (as the west cancel out)

d. 3 miles is your answer

If x is a real number such that $x^3 = 729$ , then $x^2+√(x)$ equals?

Answers

$x^3 = 729 \n \n x^2+√(x) =? \n \n x^3 - 729=0 \n \n x^3-9^3 = 0\n \n(x-9)(x^2+9x+81)=0$

$x^2+9x+81 =0 \ \ or \ \ x-9 = 0\n \n\Delta =b^2-4ac =9^2-4\cdot 1\cdot 81=81- 324 =-243 \n \n and \ we \ know \ when \ \Delta \ is \ negative, \ theres \ no \ solution \n or \n x-9=0 \n \nx=9$

$a^3-b^3=(a-b)(a^2+ab+b^2) \n\n \n x^2+√(x) = 9^2+√(9)=81+3 = 84$

First, we find the value of 'x.'
$x^(3)=729 \n x= \sqrt[3]{729}$
x=9

$x^(2) + √(x)$
$9^(2)$ + $√(9)$
81+3
= 84
$x^(2) + √(x)$ =84

The pattern is semi-complicated and hard to explain.
From the first number to the second, they subtracted 8. Then added 4. Then subtracted 9. And added 4. And subtracted 10. And added 4.
So I subtracted 11. Then added 4. And subtracted 12. Then added 4. Etc.
