Answer:
x = 10/3
x = 3 1/3
(3 whole number, 1/3)
Step-by-step explanation:
To solve for x, we just simplifying the expression.
Be mindful of the signs!
Let's go on now!
x + 7/-3 = 1
Begin by Multiplying all through by -3.
The expression becomes:
(-3 * x) + (7/-3) * -3 = 1 * -3
-3x + 7 = -3
-3x = -3 -7
-3x = -10
Divide both sides by the coefficient of x.
x = -10 / -3
x = 10/3
x = 3 1/3
(3 whole number, 1/3)

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:
2,100 people
Step-by-step explanation:
~Divide to find the number of people in fifths
3,500 / 5 = 700
~Multiply to find 2/5 of the total people
700 * 2 = 1,400
~Subtract to find the number of people against building the school.
3,500 - 1,400 = 2,100
Best of Luck!
