Generally the standard deviation is mathematically represented as

substituting value

The percentage of a cucumber give the crop amount between 778 and 834 kg is mathematically represented as

Generally 
So


From the z-table the value for 
and
So


The percentage is

The probability of cucumber give the crop exceed 900 kg is mathematically represented as

substituting values


From the z-table the value for 
Answer:P=2x + 2y + 8
Step-by-step explanation: Perimeter (p) =2L+ 2w
P= 2(x+5)+2(y-1)
Remove bracket
P=2x+ 10 +2y - 2
P=2x+2y+8

We know that
[scale factor]=1/2
[dilated area of circle]=[original area of circle]*[scale factor]²
so
[dilated area of circle]=[original area of circle]*[1/2]²
[dilated area of circle]=[original area of circle]*[1/4]
therefore
the answer is
<span>The area will be 1/4 the original</span>
Answer:
Hey there!
The range is the possible y values, so the range of this graph would be all real numbers less than or equal to -6.
