Use the figures below to answer parts A and B

The given heights:

6, 9, 10, 10, 10, 11, 11, 12, 12, 13, 14, 16, 17.

The first step is to find Median in order to divide the above series into lower and upper quartiles.

To find the median, just cross out the first and the last value until you left with the single value, as the number of elements is odd.

Like first 6 would cancel the last 17,
second number 9 would cancel the second last number 16,
and so on.

By doing above exercise, we are left with 11.

So the median = 11.

Now any number below the median 11 would be in lower quartile series, while other half would be in upper one.

To find the lower quartile, find the median of 6, 9, 10, 10, 10, 11:
Now the numbers are even; therefore, we would do the above-mentioned exercise of cancelling first and the last element until we are left with just 2 elements:

The two elements are: 10, 10.
Take average = (10 + 10) / 2 = 10

So lower quartile = 10

To find the upper quartile, find the median of 12, 12, 13, 14, 16, 17:
Now the numbers are even; therefore, we would do the above-mentioned exercise of cancelling first and the last element until we are left with just 2 elements:

The two elements are: 13, 14.
Take average = (13 + 14) / 2 = 13.5

So Upper quartile = 13.5

The interquartile range = Upper Quartile - Lower Quartile = 13.5 - 10.0 = 3.5

So the correct option is (A) 3.5

A byte is a unit used to measure computer memory. Other units are based on the number of bytes they represent. The table shows t

NeTakaya

Answer:

A) $2^{30}$ kilobytes
B) $2^{30}$ megabytes
C) In order to convert the number of bytes per unit to the number of bits per unit you need to multiply the number of bytes by 8.

Step-by-step explanation:

Part A: How many kilobytes are there in 1 terabyte? The final answer should be left in exponential form.

1 terabyte = $2^{40}$ bytes

1 kilobytes = $2^{10}$ bytes

⇒ 1 terabyte = $2^{40} / 2^{10} = 2^{30}$ kilobytes

Part B: How many megabytes are there in 1 petabyte? The final answer should be left in exponential form.

1 megabyte = $2^{20}$ bytes

1 petabyte = $2^{50}$ bytes

⇒ 1 petabyte = $2^{50}/2^{20}=2^{30}$ megabytes

Part C: Another unit used to measure computer memory is a bit. There are 8 bits in a byte. Explain how you can convert the number of bytes per unit to the number of bits per unit.

In order to convert the number of bytes per unit to the number of bits per unit you need to multiply the number of bytes by 8.

1 byte = 8 bits

2 bytes = 2*8 bits = 16 bits

3 bytes = 3*8 bits = 24 bits

etc.
