Answer: 68.27%
Step-by-step explanation:
Given : Mean value of land and buildings per acre from a sample of farms :
The data set has a bell-shaped distribution. i.e. it follows Normal distribution.
Using 
, for x= 1300 , we have
For x= 1700 , 
Using standard normal z-value table,
P-value = P(-1<z<1)=
[Round to nearest 4 decimal places.]
i.e. The percent of farms whose land and building values per acre are between $1300 and $1700 = 68.27%
Answer:
x = 12.75
Step-by-step explanation:
10.2 : x = 0.8
x = 10.2 : 0.8
= 102/10 : 8/10
= 102/10 × 10/8
= 102/8
= 12.75
Step-by-step explanation:
Aaaaaaaaaaaaaaaaaaaaaaaaaa
There is no graph in your question. If p is number of reams of paper, and c is number of ink cartridges, then
3p + c = 234, wich p and c natural numbers (including 0)
This means that 13 ink cartridges and 0 paper will satisfy the end amount, but also 0 ink cartridges and 39 paper. There are 14 combinations possible.
Answer:
Step-by-step explanation:
To find y=mx+b we need to identify two points. I picked (20,45) and (50,65)
From these two points we can find the slope, m.
m=(y2-y1)/(x2-x1)
m=(65-45)/(50-20)
m=20/30=2/3 so now our line is
y=2x/3+b, we can solve for b using either point, I’ll use (20,45)
45=2(20)/3+b
45=40/3+b
b=45-40/3
b=(135-40)/3
b=95/3 so the line is
y=(2x+95)/3
