Answer:
Discrete(b,c and d)
Continuous (a and e)
Step-by-step explanation:
<u>Discrete</u>
Discrete Random variables are variables that can only take on integer values. Therefore the following are discrete variables.
b. The number of fish caught during a fishing tournament. e.g. 6 fishes
c. The number of statistics students now reading a book. e.g. 12 Students
d. The number of textbook authors now sitting at a computer. e.g. 9 Authors
<u>Continuous</u>
Continuous random variables can take on an uncountable number of values.
a. The time it takes for a light bulb to burn out. e.g.178.897 seconds
e. The height of a randomly selected giraffe. e,g 16.67 feet
Answer:
518
Step-by-step explanation:
14 x 74 = 1036 1036 / 2 = 518

So
x=earned
x>200
they paid their parrents 28 for supplies (this assumes that they paied 28 altogether and not 28 each)
so subtract 28 from pay
new pay=y
y>200-28
y>172
divided it among themselves (3)
172/3=57 and 1/3=57.33
they each earned more that $57.33
There are 20 students in the class.
Find the are of the pool by dividing the volume by the depth:
1960 / 4 = 490
The pool is 490 square feet.
Area is found by multiplying the length by the width.
Let the width = X
We are told the length is 2.5X ( 2.5 times longer)
So we now have 2.5x * x = 490
2.5x * x = 2.5x^2
Now we have 2.5x^2 = 490
Divide both sides by 2.5:
x^2 = 490/2.5
x^2 = 196
find X by taking the square root of 196:
x = √196
x = 14
The width is 14 feet
The length is 2.5 * 14 = 35 feet
