Answer:
Isosceles trapezoid
Step-by-step explanation:
Plotting the points show us that this shape is at least a trapezoid, by the fact that only one pair of parallel sides.
To show that it is isosceles is done by finding the lengths of the diagonals, which takes quite long, but here, it is very clear that the two non-parallel sides are congruent, and the parallelogram is perfectly symmetrical.
Answer:
3300
Step-by-step explanation:
Formula
Gross Salary = Basic + Commission
Givens
Basic = 3000
% = 12%
Solution
Gross = 3000 + 12/100 * 2500
Gross = 3000 + 30000/100
Gross = 3000 + 300
Gross = 3300

Answer:
9.48683298051
Step-by-step explanation:
Answer:
mean: 4
median: 5
mode: 5
Step-by-step explanation:
Hi there!
Let's first start with the mean
the mean is the average of all of the numbers; we add up how many hours each week each student spent playing video games and then divide it by how many people responded (9)
(0+5+7+5+3+0+9+5+2)/9
add all of the numbers on top
36/9
divide
4
the mean is 4
now find the median, or the value that separates the upper half from the lower half of the data (it's the "center" value).
first, list the numbers in order from least to greatest
0,0,2,3,5,5,5,7,9
now get rid of the largest number and the smallest number (0 and 9)
the set is now:
0,2,3,5,5,5,7
now get rid of the largest and smallest number in the new set (0 and 2)
the set becomes:
2,3,5,5,5
get rid of the largest and smallest number in the new set (2 and 5)
3,5,5
get rid of the largest and smallest number in the new set (3 and 5)
5
the median is therefore 5
the mode is the number that occurs most frequently in the data set
here's our list again of all of the numbers from least to greatest:
0,0,2,3,5,5,5,7,9
we can count how many times each number appears to find the mode
0: 2 times
2: 1 time
3: 1 time
5: 3 times
7: 1 time
9: 1 time
since 5 appeared the most times, then the mode is 5
hope this helps!
