Zeolite organized a canned food drive. She worked a total of 12 2/3 hours. She worked 3 1/6 hours each day that she worked. How

galina1969 [7]

She worked 4 days on the food drive because to do math with these two fractions, you have to give them the same denominator. So, 12 2/3 becomes 12 4/6. Then, how many times does 3 go into 12? 4 times so the answer is 4. Hope this helped :)

Your friend has a z-table, and you don't. You ask your friend to look up the area in a tail on the left hand side of the normal

tiny-mole [99]

Answer:

d. 0.4013

Step-by-step explanation:

Half of the area under the normal curve is found to the left of the midpoint, where z=0. For negative values of z, the area under the curve is less than half.

Area under a normal curve is always a positive value between 0 and 1, so will never be negative.

The only value that can be an area in a left-hand tail is 0.4013.

_____

<em>Additional comment</em>

That value corresponds to z ≈ -0.25.
