We must first Isolate the Variable by removing factors that don't contain the variable:

2(x + 7) < 12
2x + 14 < 12
2x + 14 - 14 < 12 - 14
2x < -2
2x / 2 < -2/2
x < -1

Hope this helps!

Describe 2 ways you could evaluate 37% of the sum of 27 3/5 and 15/9

miskamm [114]

First way is create an equation like this:
$0.37(27 \frac{3}{5}+ \frac{15}{9})$
and calculating it.
Second way is to find 37% of each number and then add it
$0.37*27 \frac{3}{5}$ + $0.37* \frac{15}{9}$
In both cases the result is 10.829

Answer:

The answer is "0.142466".

Step-by-step explanation:

Using the p formula for the proportion of nonconforming units through the subgrouping which can vary in sizes:

$p =\frac{np}{n}\\\\$

$\bar{p}=\frac{\Sigma np}{\Sigma n}\\\\$

Defects $= \frac{5}{100} \times 50 \\\\$

$p = \frac{5}{100} \times \frac{50}{50}=0.05\\\\$

It calculates the controls limits through the p-chart that is:

$UCL_{p},LCL_{p}=\bar{p} \pm \sqrt{\frac{\bar{p}(1-\bar{p})}{\bar{n}}}\\\\$

So, the upper control limits:

$= 0.05 + 3 \times \sqrt{(\frac{0.05\times(1-0.05)}{50})} \\\\= 0.142466$
