Answer:
525 children attended the concert.
Step-by-step explanation:
Given that:
Total number of people who attended concert = 2500
Adult females = 47%
Adult males = 32%
Percent of children = (100-47-32)% = 21%
Number of children = 21% of people who attended
Number of children = ![\frac{21}{100}*2500](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B100%7D%2A2500)
Number of children = 0.21*2500 = 525
Hence,
525 children attended the concert.
Answer:
It's 7:26 over here
Step-by-step explanation:
I domt get what you mean by coordinate pair could you explain plseas
The z-score for 45cm is found as follows:
![z=\frac{45-49.2}{1.8}=-2.33](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B45-49.2%7D%7B1.8%7D%3D-2.33)
Reference to a normal distribution table, gives the cumulative probability as 0.0099.
Therefore about 1% of newborn girls will be 45cm or shorter.
(4x28)+64
112+64
176
Rounded to the nearest ten it would be 180
