(2x-y)+(3y-x) = 2y+X = 25
25 = 2:1 = 2Y:X
25/3 = 25/3
25/3 * 2 = 50/3 = 2y
x = 25/3
y = 25/3
Hope this helps! :)
Answer:
Approximately 68%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 1, standard deviation = 0.05.
Estimate the percent of pails with volumes between 0.95 gallons and 1.05 gallons.
0.95 = 1 - 0.05
1.05 = 1 + 0.05
So within 1 standard deviation of the mean, which by the Empirical Rule, is approximately 68% of values.
Answer:
Highest
Step-by-step explanation:
This is true because the largest degree is the one that influences the graph and ultimately the end behavior the most. The question you have is simply the a definition-property of degrees.
Answer:
A) (x, y) = (2-3n, 4n-1) . . . . for any integer n
B) no solution
Step-by-step explanation:
A) All coefficients have a common factor of 3, so any solution of the reduced equation will be a solution of the given equation. The reduced equation is ...
4x +3y = 5
A graph of the original shows (x, y) = (2, -1) is a solution. Then other solutions will be those values with a multiple of 4 added to y and the same multiple of 3 subtracted from x:
(x, y) = (2 -3n, 4n -1)
__
B) The left side of the equation is an even number for any integer values of x and y. The right side is an odd number. There can be no solution.
You would circle the 3 in 31, the 9 in 94, and the 1 in 17
