Answer:
volume of toy = volume of water after placing toy in it - volume of water before placing toy in it
volume of toy = 23mL - 10mL
volume of toy = 13mL
The increase in the volume of water when the toy is submerged in it is equal to the volume of the toy.
SO VOLUME OF WATER IS 13mL
You see if the graphs passes the vertical line test.
if any vertical line passes through more than one part of the graph then its not a function - just a relation.
Answer: 0.6827
Step-by-step explanation:
Given : Mean IQ score : 
Standard deviation : 
We assume that adults have IQ scores that are normally distributed .
Let x be the random variable that represents the IQ score of adults .
z-score : 
For x= 90

For x= 120

By using the standard normal distribution table , we have
The p-value : 

Hence, the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827
