Answer: Graph A
Step-by-step explanation:
Using the compound interest formula,
A = P(1+r)^n
A = 17000
r = 4% quarterly
n = 8yrs = 32 quarters of a year
P = ?
17000 = P(1+4%)^32
P = $[17000/((1+4%)^32)]
Answer:
29.5 hours
Step-by-step explanation:
Amityville to Denton is 1625 miles.
Since we know that Sarah drives at 55 mph we can divide 1625/55 and get 29.45454... and I assume that they want it rounded so it will be around 29.5 hours
The required probability for
a. 0.2058
b. 0.98
c.0.016
<h3>
What is probability?</h3>
Probability can be defined as the ration of favorable outcomes to the total number of events.
Let use binomial distribution.
Probability answering a question correctly=1/3 =0.33
Probability of not answering a question correctly
=1–1/3
=2/3
a) Out of 10 probability of answering 4 correctly
=10c4 x (0.33)^4 x (0.66)^6
Upon simplification, 0.2058
b) Find the probability for getting at least 2 correct answers
= 1 - { 10c8 x (0.33)^8 x (0.66)^2+ 10c9 x (0.33)^9 x (0.66)^1 + (0.33)^10}
= 0.98
c).Find the probability for getting 2 or 3 incorrect answers.
10c8 x (0.33)^8 x (0.66)^2 + 10c7 x (0.33)^7 X (0.66)^3
=0.002 + 0.014
= 0.016
Thus the required probabilities are: 0.2058, 0.98 , 0.016
