Answer:
-20
Step-by-step explanation:
Answer:
if the width is W and the length is 4 more of twice the width therefore the length is 2W+4
area = length × width
= 2W+4×W
=2W+4
209÷2=104.5
104.5 is the number between the two consecutive integers, therefore the first number would be 104 and the other would be 105
104+105=209
Answer:
(a) 8 balls
(b) 4 balls
Step-by-step explanation:
Let
Number of balls
For a box, the probability that there are N balls in it is:

For 2 boxes, it is:

From the question, we have:
Favorable outcome
To solve for N, we have:


Divide both sides by 2

Take log of both sides

Apply law of logarithm

Make N the subject


Approximate

Solving (b): Balls in one of the two boxes.
Here, we assume that each ball will have almost the same number of balls at a given instance;
Hence, we have:



<em>4 balls in each box</em>
Answer:
4
