To answer this item, let x be the amount of water. The concentration (in % sugar) of the solution is calculated by dividing the amount of sugar by the total amount. That is,
C = (S/ (S + x))(100%)
Substituting the known values to the equation,
75 = ((0.5/(0.5 + x))(100%)
The value of x from the equation is 0.167.
<em>Answer: 0.167 lbs of water</em>
Answer:
first blank: mean
second blank: greater than
third blank: increased
fourth blank: greater than
Step-by-step explanation:
I can't see the options in each blank, even though I completed them with reasonable options.
The MAD of a set of data is the average distance between each data value and the mean. 400 is further than the mean than the MAD. This, increases the variability of the originally data set. As a consequence, the inclusion of 400 will result in a greater MAD
Using the elimination method, the value of x in the system of equations is calculated as: 8.
<h3>How to Solve a System of Equations by Elimination?</h3>
To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8
