The future worth (F) of the current investment (P) given that the interest (i) is compounded can be calculated by the formula,
                                F = P x (1 + i)^n
where n is the number of years. Substituting the given values to solve for P,
                             1000 = P x (1 + 0.115)^6
The value of P is approximately $520.42.

A multiple choice exam has 20 questions. Each question has 3 possible answers; there is no partial credit. Only 1 answer out of
amid [387]

Answer:To find out the theoretical probability of the case given, we need to make certain assumptions.

First, we'll assume that he'll attempt all of the questions, i.e he'll attempt all 10 questions.

Next assumption is that each option in each question is equally likely to be marked by the student.

This pretty much leads us to a binomial probability distribution.

Conditions are:

   Answers 10 questions.

   Each question has 4 options with only one correct answer and all other incorrect answers.

   Student is equally likely to pick any outcome in any given question.

   Hence, probability of choosing correct answer is 1/4 = 0.25. Probability of choosing incorrect answer is 1–1/4 = 3/4 = 0.75.

   The number of trials is 10.

   Total number of success is exactly 8 and failure is 2 amongst the 10 questions in any particular order.

Now, calculation is fairly simple.

Binomial probability distribution is such that…

P(8 correct ; 2 wrong)

= 10C8 × (0.25)^8 × (0.75)²

= 405/1048576 ≈ 3.862380981 × 10^-4 ≈ 0.000386

A.) write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5.
MrMuchimi
Slope intercept form is y = mx + b

7 tickets for $5 means that 1 ticket costs 5/7 dollars

So for part a, the slope intercept form would be:

y = \frac{5}{7}x

where x is the number of tickets, and y is the price.

For part b)

The slope intercept form is:
y = 25x

where x is the number of all you can ride wristbands you buy, and y is the total price.

Jonathan weighs thirty pounds more than three times his son Aidan's weight.Their combined weight is 210 pounds.Write an equation
aalyn [17]
The equation should be
j = 30 + 3a
j + a = 210

Solving the equation
j + a = 210
(30 + 3a) + a = 210
30 + 4a = 210
4a = 180
a = 45

j = 30 + 3a
j = 30 + 3 × 45
j = 30 + 135
j = 165

Aiden's weight is 45 pounds, Jonathan's weight is 165 pounds
