7 0

Answer:

true

Explanation:

The given operators && and || are Logical operators whose execution is from left to right.so first (x>=10)&&(y>20) will be executed .Given values for x and y are 10 ,20 (10>=10 true)&&(10>20 false), which gives result as false (&& evaluates to true only when both conditions are true).so the result of this is false. next condition is ||. for this (20>=10)&&(20>20) is false and (x<y)(10<20) is true, which gives result as true.(|| evaluates to true if any one is true).

The Answer is True

In the ADT graph, the method addEdge has efficiency

Tanzania [10]

Answer:

B.O(n).

Explanation:

In an ADT graph the method addEdge uses an Array of list.So in the worst case and the worst will be when the list already has n elements in it.

So to add an edge we have to iterate over the list upto nth element and then add the edge after that.So it has to travel over n elements.

So we can say that the answer is O(n).

Write two versions of a program that reads a sequence of positive integers from the user, calculates their geometric mean, and p

givi [52]

Answer:

n = int(input("Please enter the length of the sequence: "))

print("Please enter your sequence")

product = 1

for i in range(n):

val = int(input())

product *= val

print("The geometric mean is: %.4f"%pow(product,1/n))

print("Please enter a non-empty sequence of positive integers, each one is in a separate line. End your sequence by typing done:")

product = 1

val = input()

n = 0

while(val!="done"):

product *= int(val)

n += 1

val = input()

print("The geometric mean is: %.4f"%pow(product,1/n))

Determine the number of bytes necessary to store an uncompressed RGB color image of size 640 × 480 pixels using 8, 10, 12 and 14

dexar [7]

Answer:

For 8 bits / Color Channel: 921, 600 bytes.

For 10 bits / Color Channel: 1,152,000 bytes.

For 12 bits / Color Channel: 1,382,400 bytes.

For 14 bits / Color Channel : 1,612, 800 bytes.

Explanation:

Un uncompressed RGB color image of 640 pixels wide by 480 pixels height (VGA resolution) uses 3 samples of x bits fin order to represent the quantity of each primary color (red, green and blue) in a given pixel of the image.

So, if we use 8 bits/ sample, we can calculate the bytes needed to store a complete image as follows:

640*480*3*8 bits = 7, 372,800 bits. (1)

As, by definition, 1 byte= 8 bits, we have:

Nº of bytes = 7,372,800 / 8 = 921,600 bytes. (2)

In order to get the bytes needed to store the same image, using 10, 12 and 14 bits/ sample, all we need is replacing 8 by 10, 12 and 14 in (1), and then dividing by 8 as in (2).

Proceeding in this way we obtain:

640*480*3*10 = 9,216,000 bits ⇒ 1,152,000 bytes.

640*480*3*12 = 11,059,200 bits ⇒ 1,382,400 bytes.

640*480*3*14= 12,902,400 bits ⇒ 1,612,800 bytes.
