Answer:
When two line segments have the same length, they are congruent. When two figures have the same shape and size, they are congruent. ... Similar means that the figures have the same shape, but not the same size.
The measures of variability for each class are listed:
Class A: Class B:
Range : 30 Range: 30
IQR: 12.5 IQR: 20.5
MAD: 7.2 MAD: 9.2
The interquartile range and the mean absolute deviations for class B are larger number therefore indicating that there is more variability in that data set.
He would be 25 inches tall.
40 divided by 8 would equal 5 so at age 1, he was 5 inches tall. So 5 times 5 which is how old he was, would equal 25 inches.
Answer: There are 6400 bacteria that will be present after 3 hours.
Step-by-step explanation:
Since we have given that
Initial number of bacterial cells = 100
Each cell divides to form two new cells every 30 minutes.
Number of hours = 3 hrs
Number of minutes in 3 hours = 3\times 60 = 180 minutes
Number of 30 minutes in 3 hours = 
So, our equation becomes,

Hence, there are 6400 bacteria that will be present after 3 hours.
