Answer:
To find the slope of this equation you want to put it into y=mx+b form
So in 5y=-x+2, you need to get the y by itself
Divide both sides by 5
y=-1/5x+2/5,
Slope equals -1/5x
Hope this helps ;)
It also means that a rhombus is formed from 2 identical equilateral triangles ( 2 identical 30 - 60 - 90 triangles forms one equilateral ) and a side of that triangle measures : 30 feet.
Answer:
The perimeter of the garden : 4 * 30 = 120 feet
Answer:
Length =
Breadth =
Step-by-step explanation:
Let be the length of the garden
and be the width of the garden
From the details of the cost in the question we get
Now area of the garden is
Differentiating with respect to x we get
Equating with 0
Double derivative of the area is
So, area is maximum at
So, the length and breadth of the rectangle is .
Mean: 10.5
Median: 10.5
Range: 5
--------------------------------------------
<u></u>
To find the mean you order the numbers then add then divide.
<u>Add</u>
8+9+10+10+10+11+11+11+12+13=105
<u>Divide</u>
105÷10=10.5
Mean = 10.5
--------------------------------------------
<u></u>
Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers.
Find the middle number. Put your left finger on 8 and your right finger on 13. Move your left finger to the right to 10 and move your right finger to 11.
the middle number is 10.5 so therefore it is the median.
--------------------------------------------
<u></u>
To find the range you subtract the biggest number to the smallest number.
<u>Subtract</u>
13-8=5
Therefore 5 is the range
