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:
Answer:
See the graph attached. The red arrow represents the shaded area.
Explanation:
The inequality and its solution are given:
The solution set is all real numbers less than or equal to -50.
In a number line, the values less than -50 are all the values that are to the left of -50. Thus, the graph of a ≤ -50 must include -50 and the region to the left of it.
To indicate that - 50 is included, draw a solid point; then, shade the region since it to its left.
Please, see the graph attached. The red arrow represents the shaded area.
Step-by-step explanation:
Answer:
The answer is -0.7
Step-by-step explanation:
is the right answer
Answer: Here is the explanation. also it it +3y not -3y
Step-by-step explanation:
x+y+4+2y+1=x+3y+5 because
2y+y=3y
so now you have x+3y+4+1
4+1=5
now you have: x+3y+5
if you do not understand, What i am trying to say is, you need to add all of the same things.
