Range Rule of Thumb

The range Rule of thumb states that the range is four times the standard deviation.
The standard deviation is a measure of dispersion.

$\text{Range = Maximum - Minimum}\\\text{s: Standard Deviation}\\\text{Range rule of Thumb:}\\\text{Range} = 4\times s\\\\s = \dfrac{\text{Maximum - Minimum}}{4}$

Identify the solution and graph of the given inequality. 34 > 3(2 − x)

Verizon [17]

Answer:

Solving the inequality we get x>-9.33

The graph is shown in figure attached.

Step-by-step explanation:

We need to solve the inequality: $34 > 3(2-x)$

Solving:

$34 > 3(2-x)\\$

Switching the sides , reversing the inequality and Multiply 3 with terms inside the bracket

$3(2-x)$

Subtract 6 from both sides

$6-3x-6$

Divide both sides by -3 and inequality will be reversed

$\frac{-3x}{-3} >\frac{-28}{3} \\x>\frac{-28}{3}\\x>-9.33$

Solving the inequality we get x>-9.33

The graph is shown in figure attached.

Judy buys dorito bags $0.40 each and sold them for $1.00 each. what was the percent increase

myrzilka [38]

Getting the percentage increase, we can form the formula or equation.
Percentage increase = ($1.00 - $0.40) / $0.40 * 100
Percentage increase = ($0.60) / $0.40 * 100
Percentage increase = 1.5 * 100
Percentage increase = 150%

So there is a 150% increase from the original price.
