<u><em>Answer:</em></u>
Andrew's height is
meters
<em><u>Explanation:</u></em>
We know that John's height is
meters
<u>We are given that:</u>
John is
meters shorter than Paul
<u>This means that:</u>
Paul's height = John's height + 
Paul's height =
meter
<u>We are given that:</u>
Paul is 0.25 meters taller than Andrew
<u>This means that:</u>
Andrew's height = Paul's height - 0.25
Andrew's height =
meters
Hope this helps :)
Given:
Growth rate = 30% decrease
To find:
The growth factor associated with the given growth rate.
Solution:
The general exponential function is:


Where, a is the initial value, r is the growth rate in decimal and
is the growth factor.
It is given that the growth rate is 30% decrease. So,



Now,




Therefore, the growth factor is 0.7.
Answer:
The tabulated value is less than the calculated value, therefore we accept the null hypothesis and It show that there is a difference in the mean overall distance of brands.
Step-by-step explanation:
