The value of t is 6.65
<h3>What is exponential function?</h3>An exponential function is a mathematical function of the following form: f ( x ) = a^x. where x is a variable, and a is a constant called the base of the function.
Given:
A= 210 million
P= A e^(kt)
225 = 210 * e ^ (0.0069t)
225/210= e ^ (0.0069t)
1.07 = e ^ (0.0069t)
Taking log on both side
log 1.047 = 0.0069 t log e
t= log ( 1.047) / 0.0069
t= 6.65
Hence, value of t is 6.65.

Answer:
No, the ratios of the number of students on the team to the number of students trying out the same for both the boys and the girls are not same.
Step-by-step explanation:
Finding ratio of of the number of girls students on the team to the number of students trying
Total girls who tried = 28
No of girls selected in team = 12
Finding ratio of of the number of boys students on the team to the number of students trying
Total Boys who tried = 30
No of boys selected in team = 15
No, the ratios of the number of students on the team to the number of students trying out the same for both the boys and the girls are not same.
