The test scores of 8 students are shown in the table above. Let m be the mean of the scores and M be the median of the score. What is the value of M-m?
Answers
Answer:
0
Step-by-step explanation:
Both M and m equal 81
The resultant value of the difference of Median and Mean will be 0.
Define Mean, Median and Mode for a given set of data.The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
The mode is the number that occurs most often in a data set.
Given is the test scores of 8 students are shown in the table.
We can write the data in the order least to greatest as -
67, 75, 75, 75, 87, 87, 91, 91
Mean = 648/8 = 81
Median = (75 + 87)/2 = 81
So, we can write (Median- Mean) as 81 - 81 = 0
Therefore, the resultant value of the difference of Median and Mean will be 0.

Center (-1,-5) radius= 2
Center (1,-5) radius= 2
Center (-1, 5) radius= 4
Center (-1, 5) radius= 2
Answers
Answer:
The equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where h, k, is the center and r is the radius.
So, in this case: the center is (-1, 5) and the radius is 2.

After 10% tax, the phone cost $220. What was the original price?
Answers
Answer:
$198
Step-by-step explanation:
To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!

Five years ago, Charlie was twice older than Priya. What are their ages now if in 3 years the um of their ages will be 76?
Answers
Answer:
Charlie is 45 and Priya is 25
Step-by-step explanation:
Answer:
present age of charlie is 45 years
present age of priya is 25 years
Step-by-step explanation:
Let start from five years ago
Let at that age of Priya was x years
given that
Charlie was twice older than Priya
age of Charlie = 2x
_____________________________________________
present age of charlie = age 5 years ago + 5 years = 2x + 5
present age of priya = age of priya 5 years ago + 5 years x + 5 = x + 5
_________________________________________________
age of charlie 3 years from now = present age of charlie + 3 years
age of charlie 3 years from now =2x + 5 + 3 = 2x + 8
age of priya 3 years from now = present age of priya + 3 years
age of priya 3 years from now =x + 5 + 3 = x + 8
Given that
in 3 years the sum of their ages will be 76
thus
sum of their ages in 3 years from now = x + 8 + 2x + 8 = 76
=> 3x + 16 = 76
=> 3x = 76-16 = 60
=> x = 60/3 = 20
Thus,
present age of charlie = 2x + 5 = 2*20 + 5 = 45 years
present age of priya = x + 5 = 20 + 5 = 25 years

Segment AB and segment CD intersect at point E. Segment AC and segment DB are parallel. If m∠A=41m∠A=41o and m∠D=56m∠D=56o, find the m∠AECm∠AEC.
Answers
Answer:
m∠AEC = 83°
Step-by-step explanation:
∠C and ∠D are alternate angles and are congruent because segment AC is parallel to DB
Therefore, m∠C = 56°
Sum of measures of angles of a triangle is 180.
So, m∠A + m∠C + m∠AEC = 180
41 + 56 + m∠AEC = 180
m∠AEC + 97 = 180
m∠AEC = 83°
