1 answer:
it will take 8 months for these trees to be same height
Further explanation:
Let x be the number of years then,
Type A is 5 feet tall and grows at a rate of 19 inches per year
The expression for Type A is:
5+19x
Type B is 7 feet tall and grows at a rate of 16 inches per year
The expression for Type B is:
7+16x
Putting both of them equal will give us the time in which both to be same height
Hence, it will take 8 months for these trees to be same height

Total number of red tiles:
Probability of getting red in one draw:
<em>This means that you would expect to get red or 30% of the times.</em>
<em>Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:</em>
<em></em>
