Answer:
The cost of tuition fee after 4 years is $15,149.72.
Step-by-step explanation:
Exponential function:
A= the amount after n years
P= Initial amount
r= rate of increasing
n= time in years
The cost of tuition at a college is $12,000. It is increasing at the rate of 6% each year.
Here, P= $12,000, r= 6%= 0.06, n= 4 years.
=$15,149.72
The cost of tuition fee after 4 years is $15,149.72.
Answer:
The probability of the event that first ball that is drawn is blue is .
Step-by-step explanation:
Probability:
If S is is an sample space in which all outcomes are equally likely and E is an event in S, then the probability of E,denoted P(E) is
Given that,
An urn contains two balls B₁ and B₂ which are blue in color and W₁,W₂ and W₃ which are white in color.
Total number of ball =(2+3) =5
The number ways of selection 2 ball out of 5 ball is
=5²
=25
Total outcomes = 25
List of all outcomes in the event that the first ball that is drawn is blue are
B₁B₁ , B₁B₂ , B₁W₁ , B₁W₂ , B₁W₃ , B₂B₁ , B₂B₂ , B₂W₁ , B₂W₂ , B₂W₃
The number of event that the first ball that is drawn is blue is
=10.
The probability of the event that first ball that is drawn is blue is
