Zepler [3.9K]2 years ago
4 0

Answer:

The first HDD was created by IBM in 1956 and was the size of a refrigerator. The total storage capacity was 5 MB and only two heads were used to read the disks. The 1970s offered a hard disk drive in much smaller shells with the ability to store roughly 60 MB.

Assume X and Y are indepndent. Assume that X has mean 10 and standard deviation 8. Assume Y has mean 12 and standard deviation 6
Vitek1552 [10]

Answer:

\sigma_z = 10

Explanation:

Given

\bar x = 10

\sigma_x = 8

\bar y = 12

\sigma_y = 6

z = x + y

Required

\sigma_z

This is calculated as:

\sigma_z = \sqrt{Var(x) + Var(y)}

Calculate Var(x)

We have:

Var(x) = \sigma_x^2

Var(x) = 8^2

Var(x) = 64

Calculate Var(y)

We have:

Var(y) = \sigma_y^2

Var(y) = 6^2

Var(y) = 36

So, we have:

\sigma_z = \sqrt{Var(x) + Var(y)}

\sigma_z = \sqrt{64 + 36}

\sigma_z = \sqrt{100}

\sigma_z = 10

How do you think calculator of a computer works? describe the procedure.
Leviafan [203]

Explanation:

calculators work by processing information in binary form. We're used to thinking of numbers in our normal base-ten system, in which there are ten digits to work with: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The binary number system is a base-two system, which means there are only two digits to work with: 0 and 1. Thus, when you input numbers into a calculator, the integrated circuit converts those numbers to binary strings of 0s and 1s.

The integrated circuits then use those strings of 0s and 1s to turn transistors on and off with electricity to perform the desired calculations. Since there are only two options in a binary system (0 or 1), these can easily be represented by turning transistors on and off, since on and off easily represent the binary option

Once a calculation has been completed, the answer in binary form is then converted back to our normal base-ten system and displayed on the calculator's display screen.
