The question states, "$6.85 per pound find the total cost if Ameila bought 4 pounds".

So you know she bought 4 pounds costing $6.85.

It is equal to 4(6.85).

If you apply the distributive, it will be 6.85+6.85+6.85+6.85.

This is equal to 27.4

ch4aika [34]

Answer:

The percentage of men meeting the height requierements is 11.47%.

As women have a less mean height, closer to the height requierments than men's mean height, it is expected that more percentage of women will fall within the height requirements.

Step-by-step explanation:

We have men's height normally distributed with mean 67.4 in and standard deviation 3.7 in.

The amusement park requires heights between 57 in and 63 in.

We can calculate the proportion using the z-scores and the standard normal probability distribution.

z_1=\dfrac{X_1-\mu}{\sigma}=\dfrac{57-67.4}{3.7}=\dfrac{-10.4}{3.7}=-2.811\\\\\\z=\dfrac{X-\mu}{\sigma}=\dfrac{63-67.4}{3.7}=\dfrac{-4.4}{3.7}=-1.189

P(57

The percentage of men meeting the height requierements is 11.47%.
