a reduced fat cookie contains 11g of fat per serving. in order for food to be termed 'reduced fat', it must have at least 20% le
Svetllana [295]

Personally, I did this in a kinda weird way but I think that it should be correct

-How I figured the answer out-

I took 11g and wrote 80% next to it, because after all it has 80% less fat than the regular cookie.

Then, I scaled it down to 10% by dividing by 8, which got me

1.375g = 10%

And finally, I multiplied by 10 to now have 100% (meaning, a regular serving size cookie) and be left with the result: 13.75g

-The answer-

13.75g   (don't forget to write the units)

Have a great day :)

The length of a text message is conversation is normally distributed with a mean of 2 min and a standard deviation of 0.5 min.
Dmitry_Shevchenko [17]
\mathbb P(X>3)=\mathbb P\left(\dfrac{X-2}{0.5}>\dfrac{3-2}{0.5}\right)=\mathbb P(Z>2)

About 95% of a normal distribution lies within two standard deviations of the mean, so 5% lies without, and since the distribution is symmetric, 2.5% lies to either side. This means

\mathbb P(X>3)=\mathbb P(Z>2)\approx0.025
