Answer:

110 liters of water

Step-by-step explanation:

Let

x ----> liters of water

f(x) ---->  the percent of the sat in the new mixture

we have

f(x)=\frac{1.2}{x+10}

For f(x)=1\%=1/100=0.01

substitute in the equation

0.01=\frac{1.2}{x+10}

solve for x

x+10=\frac{1.2}{0.01}

x+10=120\\x=120-10\\x=110\ L

A set of data has a normal distribution with a mean of 5.1 and standard deviation of 0.9. Find the percent of data between 6.0 a
jolli1 [7]

The percent data between 6.0 and 6.9 would be 13.59%. Here’s the complete solution for this specific problem.

<span>z = (X - Mean)/SD </span><span>
<span>z1 = (6 - 5.1)/09 = + 1 </span>
<span>z2 = (6.9 - 5.1)/09 = + 2 </span>
<span>Required Percent = P(6 < X < 6.9)*100 </span>
<span>= P(1 < z < 2)*100 </span>
<span>= [P(z < 2) - P(z < 1)]*100 </span>
<span>= [0.9772 - 0.8413]*100 </span>
<span>= 0.1359*100 </span>
<span>= 13.59%

I am hoping that this has answered your query.</span></span>
