Answer:
The values of x and y is given by the equation
.
Step-by-step explanation:
Given : Five whole numbers are written in order 4 6 x y 10
, the mean and median of the five numbers are the same.
To find : The values of x and y ?
Solution :
Observations 4, 6, x, y, 10.
Mean is summation of observation divided by number of observation.
i.e. 


Median is middle term of observations.
Median of odd terms
term

term
The mean and median of the five numbers are the same.
i.e. 


The values of x and y is given by the equation
.
Two thirds is equal to 66.666666 etc. percent so 64 is pretty close to 66 so I would consider it right.

Answer:
<em>The area of Marlien's living room is 420 square ft</em>
Step-by-step explanation:
Before calculating the real dimensions of Marlien's living room, we must find the value of x.
Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.
The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:

Simplifying:
-10 + x - 2 = 2
x = 10 + 2 + 2
x = 14
Since x=14 feet, the dimensions of Marlien's living room are
width=x=14 feet
length=2x+2=30 feet
Thus the area is:
A = 14*30 = 420 square ft
The area of Marlien's living room is 420 square ft
Answer:
The correct answer is B) d=250t.
Step-by-step explanation:
B is the correct answer because the total distance (d) equals 250 multiplied by the minutes (t) the runner has ran.
