Mean, Median, and Mode
Mean - Add all the numbers then divide by the number of numbers you added.
Median - The center of a set of numbers. (In a, b, c, d - b+c/2 is the median.)
Mode - The number that appears the most in a set of numbers.
They are called measures of center because they are statistics that describe the center of a set of data.
Answer:
8.5 $
Step-by-step explanation:
Let Kiran 's salary is x $ per hour
hence cousin 's salary is x+ 30% of x per hour
or x+0.3x or 1.3x per hour
cousin 's earning 27(1.3x) = 35.1 x
kiran 's earning 23x
hence 35.1x +23x = 493.85
58.1x = 493.85
x = 493.85/ 58.1
x = 8.5 $
Answer:
$780
Step-by-step explanation:
600*.30=180
600+180=780
Answer:
(-1-√33)/2, (-1+√33)/2
Step-by-step explanation:
If one of them is x, then it satisfies ...
x + -8/x = -1
x^2 -8 = -x . . . . . multiply by x
x^2 +x = 8 . . . . . add x+8
x^2 +x + 1/4 = 8+1/4 . . . . complete the square
(x +1/2)^2 = 33/4
x + 1/2 = ±(1/2)√33 . . . . . . take the square root
x = (-1/2)(1 ± √33) . . . . . . . subtract 1/2
The numbers are approximately ...
-3.37228, 2.37228
