Add August and September for total amount of bushels:
46,100 + 8,120 = 54,220 total bushels
Divide total bushels by total acres:
54,220 / 488 = 111.1 = 111 bushels per acre
Answer:
1.) 5x
2.) 2/3x^2
3.) 53 + x
4.) 32d
5.) 19 + 2x
1.) The product of five and a number x
2.) The product of twenty four and a number x
3.) The sum of a number y and nineteen
4.) The difference of a number x and two
4.) A number y divided by two / The quotient of a number y and two
Explanation:
Keep in mind the following definitions:
- Sum means addition +
- Difference means subtraction -
- Product means multiplication *
- Square means ^2
(x + 2)² - 10 = 0 (assuming it's equal to zero)
Expand the binomial: (x + y)² = x² + 2xy + y²
Thus, x² + 4x + 4 - 10 = 0
x² + 4x - 6 = 0
(by quadratic formula)
, since we're taking the positive solution.
The standardized probability of a normally distributed data is given by
P(X < x) = P(z < (x - mean) / standard deviation)
P(X > x) = 1 - P(X < x)
P(X > 125) = 1 - P(X < 125) = 1 - P(z < (125 - 100) / 15) = 1 - P(z < 25/15) = 1 - P(z < 1.667) = 1 - 0.95221 = 0.04779 = 4.8%
Though it cannot be said to be usual, at the same time it is not unusual because 125 is above the first standard deviation of the mean but below the second standard deviation of the mean.
