Mean-20.3+12.5+7.9+17.5+15.6+14.1= 87.6
87.6/6=20.1
Median- 7.6+17.5/2= 12.55
You work out 500-82=418
Next you do 300-61=239
Finally you add 239+412=657
Answer:
7 : 9
Step-by-step explanation:
Let the first mat has a length of the sides 7x, 7y, and 7z and the second mat has a length of the sides 9x, 9y and 9z.
{Since the scale factor of the two triangular mats is
}
Hence, the perimeter of the first mat will be (7x + 7y + 7z) and the perimeter of the second mat will be (9x + 9y + 9z).
Therefore, the ratio of the perimeters of the two mats will be (7x + 7y + 7z) : (9x + 9y + 9z) = 7(x + y + z) : 9(x + y + z) = 7 : 9. (Answer)
The domain of the parabola is all real numbers
the range is [3 to infinity) or all real numbers above 3
Answer:
Step-by-step explanation:
4.6 pounds of pecans 1 pound of pecans
_________________ = ______________
50. 89 dollars x dollars
Set up an equation like this.
Cross multiply
4.6(x)=50.89(1)
divide both sides by 4.6
x=11.06 (about)
So I pound of pecans costs about 11.06 dollars
