It would take exactly 4 years for these trees to be the same height.
Step-by-step explanation:
Given,
Height of Tree A = 9 feet
1 feet = 12 inches
9 feet = 9*12 = 108 inches
Growth rate = 2 inches per year
Let,
y be the number of years.
A(y)= 108 + 2y
Height of Tree B = 8 feet
8 feet = 8*12 = 96 inches
Growth rate = 5 inches per year
B(y)=96+5y
In case of same height;
A(y)=B(y)
Dividing both sides by 3
It would take exactly 4 years for these trees to be the same height.

Answer:

Step-by-step explanation:
Delta math
In a normal distribution, the median is the same as the mean (25.3). The first quartile is the value of
such that
You have
For the standard normal distribution, the first quartile is about
, and by symmetry the third quartile would be
. In terms of the MCAT score distribution, these values are
The interquartile range (IQR) is just the difference between the two quartiles, so the IQR is about 8.8.
The central 80% of the scores have z-scores
such that
That leaves 10% on either side of this range, which means
You have
Converting to MCAT scores,
So the interval that contains the central 80% is
(give or take).
