A company conducted a survey to see whether its new toothpaste was morepopular with children or adults. Of the children surveyed
Naily [24]

Given: The information provided in the table shown

To Determine: From the options provided, the correct option that best describe the information given in the table

Solution

Given that 28% of the children used toothpaste. From the table

Children(toothpaste)=\frac{0.07}{0.25}=\frac{7}{25}\times100=28\%

Let us calculate the percentage of adult that used toothpaste

Adult(toothpaste)=\frac{0.08}{0.75}=\frac{8}{75}\times100=10.667\%\approx11\%

Hence, a smaller percentage of adults (about 11%) use the toothpaste.

The correct option is OPTION C

Can anybody show me the steps to answering this question? 7x - 2z = 4 - xy<br> (solve for x)
Fed [463]

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy= xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x(y+7)=2z+4

You divide both sides by y+7

x(y+7)/y+7= 2z+4/y+7

Which we would get x=2z+4/y+7
