There are 10 Superscript 9 bytes in a gigabyte. There are 10 Superscript 6 bytes in a megabyte. How many times greater is the st

ohaa [14]

To find the how many times greater is the storage capacity of a 1-gigabyte flash drive than a 1-megabyte flash drive we have to apply exponent operation.

The storage capacity of a 1-gigabyte is 1000 greater than 1-megabyte flash drive.

Given:

The given exponent for gigabyte is,

$10^9$

The given exponent of megabyte is,

$10^6$

<h3>What is exponent rule?</h3>

The power rule of exponent rule is defined as if raise the a number with exponent to power then we will mulitply exponent to the power times.
to change the negative exponent into a positive we have to invert the base.

Calculate the storage capacity.

$\dfrac{10^9}{ 10^6}=10^9-6}\\
\dfrac{10^9}{ 10^6}=10^3\\
\dfrac{10^9}{ 10^6}=1000$

Thus, the storage capacity of a 1-gigabyte is 1000 greater than 1-megabyte flash drive.

A sector has angle 2.5 radians and perimeter of 18cm. find the radius of the sector

babunello [35]

Answer:

4 cm

Step-by-step explanation:

Perimeter = 18cm

θ = 2.5 radian

s = rθ, s = Arc length

Perimeter of Sector, P = arc length, s + 2r

Perimeter = rθ + 2r

r = Radius

18cm = r(2.5) + 2r

18cm = 2.5r + 2r

18cm = 4.5r

r = 18 /4.5

r = 4

There are 800 students in the School of Business Administration. There are four majors in the School: Accounting, Finance, Manag

dezoksy [38]

Answer:

Major $X_i$ %

_________________________________________

Accounting 240 (240/800)*100=30%

Finance 160 (160/800)*100=20%

Management 320 (320/800)*100=40%

Marketing 80 (80/800)*100= 10%

_________________________________________

Total 800 100%

Step-by-step explanation:

For this case we can create the following table calculating the percent frequency as:

$\% = \frac{X_i}{n}$

Where $X_i$ represent the number of students for the i category and n the total sample size.

Major $X_i$ %

_________________________________________

Accounting 240 (240/800)*100=30%

Finance 160 (160/800)*100=20%

Management 320 (320/800)*100=40%

Marketing 80 (80/800)*100= 10%
