Answer:
Collection of numerical information is called Statistics
Step-by-step explanation:
From the Oxford dictionary, the definition of statistics (science) is: "the practice or science of collecting and analyzing numerical data in large quantities, especially to infer proportions in a whole from those in a representative sample".
While the definition of statistic (data) is: "a fact or piece of data obtained from a study of a large quantity of numerical data".
Statistics is a science, not a method, therefore answer can´t be a).
Not all sample data is necessarily a statistic, therefore answer can´t be b).
All statistics are numerical information.
Not all statistics are population data, therefore answer can´t be d).
Cleaned data is information filtered with a specific criterion, but not necessarily used in a statistic.
The most probable answer is c.
It would be C because |-6| + |4| is basically 6+4 because the lines make the number positive. 6+4 is 10, which is the x value for the point. That 4 unites us the distance between the points.
No
A regular polygon has interior angles that are all equivalent. Because the interior angles of a polygon must add up to 360 degrees and since 55 cannot evenly go into 360, it is not possible for all the interior angles to be 55 degrees.
Answer:
a. $5.43
b. $141.25
c. $8.75
Step-by-step explanation:
First you find the total amount you it cost for all the items
$135.82 + 4% = $141.25
You give three $50 dollar bills
50 * 3 = 150
$150 is the amount you give
--------------------------------------
141.25 - 135.82 = 5.43
$5.43 is the amount of the sale price
---------------------------------------
To find the amount is cost for all the items you add the sales tax + the original price
$135.82 + 4% = $141.25
$141.25 is the amount including the tax
---------------------------------------
Subtract
150 - 141.25 = 8.75
So you will get $8.75 back
Answer:
27π cm²
Step-by-step explanation:
step 1
Find the area of the complete circle
The area of the circle is equal to
A=πr²
we have
r=9 cm
substitute
A=π(9)²=81π cm²
step 2
Remember that the area of complete circle subtends a central angle of 360°
so
using proportion
Find the area of a sector formed by a central angle that measures 120°
81π/360°=x/120°
x=120°*81π/360°
x=27π cm²
