Answer: B. 461 acres
Step-by-step explanation:
Given : In an agricultural study, the average amount of corn yield is normally distributed with a mean of 185.2 bushels of corn per acre, with a standard deviation of 23.5 bushels of corn.
i.e. 
Let x denotes the amount of corn yield.
Now, the probability that the amount of corn yield is more than 190 bushels of corn per acre.
[Formula : 
]
[∵ P(Z>z)=1-P(Z<z)]
[using z-value calculator or table]
Now, If a study included 1100 acres then the expected number to yield more than 190 bushels of corn per acre :-
hence, the correct answer is B. 461 acres .
Answer:
6,000,000.005
Step-by-step explanation:
The correct answer in [standard form] is 6,500,000
one million= 1,000,000
six million= 6,000,000
one thousandth= .001
five thousandth= .005
6,000,000.005
Word Form: Six million and five thousandth
Answer:
x=8
NR=5 units
BI=10 units
Step-by-step explanation:
In a rectangle BRIA
AN=5 units
NR=x-3
We have to solve for x , NR and BI.
We know that
Diagonals of rectangle bisect to each other.
BI and AR are the diagonals of rectangle BRIA and intersect at point N.
AN=NR
Substitute the value of x
NR=8-3=5
By property of rectangle
BI=AR=AN+NR=5+5=10 unit
BI=10 units
It is more than 0, because you cancel the x, and you get 2+5, which is 7
Answer:
C: 0.000568 miles
Step-by-step explanation:
Essentially, the exponent on the 10 is how many places to move the decimal point, and negative versus positive dictates whether to move it right or left respectively.
