Answer:
We need approximately 1667 floppy disc to store 
bytes of data.
Step-by-step explanation:
We are given the following information in the question:
A floppy disc can store 1440000 bytes of data.
We have to convert 1440000 in a standard form.
Standard Form:
- Standard form is a way of writing down very large or very small numbers easily.
- It helps us to express large numbers in powers of 10
The standard form can be written as:
We have positive power of 10 because we have to move to the right of the decimal point.
A hard disc can store bytes of data.
Number of floppy disks needed to store the bytes of data =
Thus, we need approximately 1667 floppy disc to store bytes of data.
Answer:
Option A.
Step-by-step explanation:
In an experiment a mouse took the mean time to find its way through a maze = 18 seconds.
So the mean time μ = 18
So null hypothesis says,
H₀ : μ = 18
Then a researcher thought that the mice can complete the maze faster than the time taken earlier.
So he thinks mean time taken by 10 mice will be less than 18 seconds.
Or μ < 18
Alternate hypothesis says will be
Hₐ : μ < 18
Therefore, null hypothesis and alternate hypothesis will be
H₀ : μ = 18
Hₐ : μ < 18
Option A. will be the answer.
It's D, because the slope is 3/5, and since the shaded area is above the line, y has to be greater than the other side of the inequality.
-5/19 is negative
Which of the results are negative
Remember (-) * (-) = (+)
Solution: B, D, E
Answer:
A
Step-by-step explanation:
f(x) =³√(x+12)
Let, y=³√(x+12)
Exchanging x and y,
x=³√(y+12)
Cubing on both sides,
x³=y+12
x³-12=y
f-¹(x) =x³-12
