Which one of the following is discrete data?
a) height if a tree
b) time taken to change a light bulb
c) number of people in a room
d) weight of a baby

C) Number of people in a room is a discrete data.  

Step-by-step explanation:

Discrete Data is defined as the data than can only take certain values.

The values in the discrete data can not be continuous.

Now,

A) Height of a tree : A tree can be of any length and hence is NOT a discrete data.

B) Time Taken to change a bulb : This time taken to change the light bulb may vary from person to person. Hence it is NOT a discrete data.

C) Number of people in a room: This is a discrete data as the number of people can not be in fractions.

D) Weight of a baby : This is NOT a discrete data as the weight of a baby may vary with time. It can increase and decrease with time.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
