You can add 14 to the 9 to get pith of the problem so you'd be left with |2x+1| = 23 then it comes it quite obvious that X=11 because 2 times 11 plus 1 equals 23
Answer:
160 for each
Step-by-step explanation:
A normal distribution means that mean = median = mode. Furthermore, in a normal distribution, 68% of values are within 1 standard deviation of the mean, 95% of values are within 2 standard deviations, and 99.7% are within 3 standard deviation.
The mean is 150 and the standard deviation is 15. 165 and 135 1 standard deviation away from the mean, so 68% of values are between 135 and 165. This means that 32% of values are not between those values. A normal distributuion is symmetric, so 16% of values are greater than 1 standard distribution and 16% are less. Therefore, 16% of values (160) are less than 135 and 16% of values (160) are greater than 165
Answer:
2000 feet.
Step-by-step explanation:
Let the length of fence need be x feet.
Then we have the equation:
2lx = 19x + 4000
21x - 19x = 4000
2x = 4000
x = 2000.
