Using the normal distribution, it is found that a weight of 3125 grams would given a newborn a z-score of −0.75.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
Researching the problem on the internet, it is found that the mean and the standard deviation for the weight of newborns is given as follows:
Hence, the weight associated with Z = -0.75 is given by X:
X - 3500 = -0.75(500)
X = 3125.

Heptagon has seven sides.
Answer: Yo-yo
Concept:
In order to find the Cost Per Toy, we need to do the operation Cost / Toy.
Solve:
Slinky = Cost / Toy = 9 / 5 = $1.8 per toy
Wind-up robot = Cost / Toy = 16 / 8 = $2 per toy
<u>Yo-yo = Cost / Toy = 15 / 6 = $2.5 per toy</u>
Emoji beach ball = Cost / Toy = 3 / 2 = $1.5 per toy
Hope this helps!! :)
