Answer: The houses surveyed had between 1 and 10 rooms.
Step-by-step explanation:
The range of any data gives us a interval which contains all the data values and provides an indication of the dispersion of data its from minimum value to the maximum value.
From the histogram, the minimum number of rooms = 1
The maximum number of rooms = 10
Hence, the range of rooms in Henry's histogram is between 1 and 10 rooms.
If resistors are in series, so the current is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:
I don't know for sure I'm going to ace grade next year but I know that you you need to put the coefficients with the same variable together and the variable next to the coefficients and multiply or add or divide or subtract them and you get your answer and this is just 7th grade math I'm relying on
