Start off by ordering the numbers from least to greatest:
8, 8, 8, 10, 14, 15
Now we can find that...
the mean (average) is 10.5
the median (middle) is 9
the mode is (most repeated number) is 8
and the range (difference of the largest and smallest number) is 7
The problem statement tells us ...
... paycheck = 4000 + 0.09×sales
and that the paycheck amount is 11650. Substituting that into the above equation and solving for sales, we have ...
... 11650 = 4000 + 0.09×sales
... 7650 = 0.09×sales . . . . . . . . . . subract 4000
... 7650/0.09 = sales = 85000 . . . divide by 0.09
John's sales during that month were $85,000.
15x6% and then add that to 15
And that’s your answer
8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
Given:
square shape.
diagonal = 44 inches
The frame is square shape therefore its side lengths are equal. We need to solve for the side length using the diagonal.
a = √2 d/2
a = √2 44/2
a = √2 22
a = 1.414 * 22
a = 31.112 or 31 inches
Perimeter: 31 inches * 4 sides = 124 inches
