Let X be a random variable representing the weight of a pack of cookies.
P(X < 250) = P(z < (250 - 255)/2.5) = P(z < -5/2.5) = P(z < -2) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275 = 2.3%
Therefore, we conclude that about 2.3% of the packs weighed less than 250 grams.
Answer:
36
Step-by-step explanation:
4 x 9 = 36
Check the picture below.
so the volume will simply be the area of the hexagonal face times the height.

Choice A is the only one that is changing at a constant rate. The reason is that for all three other choices the new rate is based on a different amount after the percent has been applied or the doubling of the ants has been applied. The price per day for the lunch Is constant because whatever the number of days is the amount would always stay the same for each of those days.
The other endpoint is (10, -8
