If a multiple-choice test consists of 5 questions, each with 4 possible answers of which only 1 is correct, (a) in how many different ways can a student check off one answer to each question?
(b) in how many ways can a student check off one answer to each question and get all the answers wrong?

Answers

Answer:

  (a)  1024 ways

  (b)  243 ways

Step-by-step explanation:

When answers are independent, the total number of ways all questions can be answered is the product of the number of ways each question can be answered.

__

(a)

The first question can have one answer 4 ways. The second question can be answered 4 ways for each of the ways the first question was answered. That is, the two questions can be answered 4×4 = 16 ways. Similarly, each additional question multiplies the number of ways the questions can be answered by 4.

The 5 questions can be answered 4×4×4×4×4 = 4^5 = 1024 ways.

__

(b)

There are 3 ways to answer the first question incorrectly. Each additional question can be answered incorrectly 3 ways for each of the ways previous questions were answered. The total number of ways all questions can be answered incorrectly is ...

  3^5 = 243

A student can answer all questions wrong in 243 different ways.

What is the future value of a 5-year annuity due with annual payments of $ 2,535 , evaluated at a 14.18 percent interest rate? Enter your answer to the nearest $.01. Do not use $ or , signs in your answer. Enter your answer as a positive number.

Answers

Answer:

  $19,201.09

Step-by-step explanation:

The future value of the annuity due can be found using any of a number of apps, calculators, or spreadsheets. It can also be found using the formula ...

  A = P(1 +r)((1 +r)^n -1)/r

where P is the annual payment, r is the annual interest rate, and compounding is yearly for n years.

  A = 2535(1.1418)(1.1418^5 -1)/0.1418 ≈ 19,201.09

The value will be $19,201.09.

Given that the line y=ax+b passes through the points A(0; 3) and B(-2;7), how do I find the values of a and b?

Answers

First you have find the slope (a) in order to find the value of the y intercept (b).

To compute the slope, you simply have to find the difference of y coordinates and divide them by the difference of x coordinates:

a = (y2-y1)/(x2-x1)
a = (7-3)/(-2–0)
a = 4/-2
a = -2

To compute the y intercept denoted by b, we substitute the value of a with -2 in the formula and choose any point (x,y) and substitute their values in the formula as well. Like so:

I choose point A:

3 = (-2)(0) + b
3 = b

Two lines are intersecting. What is the value of x?

Answers

Answer:

The correct answer is x = 51.

Step-by-step explanation:

We have been given an image of two intersecting lines. We are asked to find the value of x.

We can see that both angles are supplementary (adding up to 180 degrees), so we can set an equation as:

x + 23 + 2x + 4 = 180

x + 2x + 4 + 23 = 180

3x + 27 = 180

3x + 27 - 27 + 180 - 27

3x = 153

3x/3 = 153/3

x = 51

Therefore, the value of x is 51.

The load requirement in your plan is 60 psf at a joist spacing of 16 inches . If the room dimensions are length 13 feet 2 inches and width 11feet 7 inches are 2 by 10 boards appropriate

Answers

The correct answer is; No, because the 2 x 10 boards can support neither the width nor length of the room.

How to find the dimensions?

We are given;

Load requirement = 60 psf

Joist Spacing = 16 inches

Length of room; 13 feet 2 inches

Width of room; 11 feet 7 inches.

Since we want to consider whether 2 by 10 boards are appropriate, this  length of  2 by 10 will not be appropriate because it cannot cover up for a room with dimensions of 13 feet 2 inches and 11 feet 7 inches.

Thus, we can conclude that No, because the 2 x 10 boards can support neither the width nor length of the room.

The missing options are;

A. Yes, because 2 x 10 boards can support the width and length of the room

B. Yes, because 2 x 10 boards support the 70 psf

⇒ 4(6 × 1.5) + 2(1.5 × 1.5)

⇒ 36 + 4.5

⇒ 40.5 inch²

Therefore, the surface area of the rectangular prism is 40.5 inch²

#3

The polygons that would be used in this net surface area are:

✔ square

Answer:

40.5 in²

Step-by-step explanation:

Formula applied :

Surface Area (rectangular prism)

⇒ 2(Length × Width + Width × Height + Length × Height)

=============================================================

Given :

⇒ Length = 6 inches

⇒ Width = 1.5 inches

⇒ Height = 1.5 inches

============================================================

Solving :

⇒ Surface Area = 2(6 × 1.5 + 1.5 × 1.5 + 6 × 1.5)

⇒ Surface Area = 2(9 + 2.25 + 9)

⇒ Surface Area = 2 × 20.25

i) Calculate the number of people like black coffee?
ii) How many people don’t like any of the drinks?

Answers

Answer:

32

Step-by-step explanation:

Answer:

  i) 52

  ii) 66

Step-by-step explanation:

This sort of problem is usually solved using some sort of table or Venn diagram. We have used a table in the attachment such that each of the cells in the grid represents one of the 8 possible combinations of coffee, tea, or chocolate.

The numbers in black are given directly by the problem statement. The numbers in blue are calculated from the numbers in black and one of the other given numbers in the problem statement. The numbers in red are calculated so the totals work out correctly.

The cells shaded blue-gray are "one and only one" of the drinks. The cell shaded purple-gray is "don't like any".

__

i) black coffee

We assume that any form of "coffee" is "black coffee." The problem statement tells us 52 people like coffee.

__

ii) none

The last number we calculated is the number who like none of the drinks: 66. This brings the total of non-coffee drinkers to 148.

_____

Additional comment

As noted above, the colors more or less indicate the order of the calculations. We started with 36 who like coffee only, and 46 who like coffee and not tea. That means 46-36=10 like coffee and chocolate, but not tea.

Since 16 like coffee and chocolate, that leaves 16-10=6 who like coffee and tea and chocolate (all three).

96 like chocolate, but 16 of those like chocolate and tea. The other 80 like chocolate, but not tea.

46+16=52, so there must be 0 who like coffee and tea, but not chocolate.

The number who like only one is 108. We already have 36 that are coffee only, 80-10 = 70 that are chocolate only, so there must be 108 -70 -36 = 2 who like tea only.

Now, we can finish filling the top row of the table and the totals in the bottom row.

Answers

Answer:

Step-by-step explanation:

Angles in a triangle add up 180 :

180 = 107 + 33 + y

y = 180 - (107+33)

y = 180 - 140

y = 40

Angles on a straight line add up to 180 so :

180 = x + y

180 = x + 40

x= 180 - 40

x = 140

CATS ARE QUIETIf noise levels are a concern in your living situation, cats are a great choice of pet. Even the quietest bark will likely be much louder than the most insistent meowing. Depending on the cat, you may need to worry about other sounds such as them knocking things off of surfaces or running around at top speed, but they are still likely to be more quiet overall.2. CATS ARE LOW MAINTENANCECompared to dogs, cats are a low maintenance pet. They dont require formal training, they dont need to be taken out multiple times a day, and theyre even able to take care of basic self-cleaning. Of course, long-haired cats will still require regular grooming, but it will likely involve less regular grooming than long-haired dogs.3. CATS ARE EASY TO HOUSE-TRAINOne of the biggest challenges dog owners need to overcome is the process of house-training a new puppy. Kittens, on the other hand, usually know how to use the litter box as soon as you bring them home. All you need to do is show them where it is, and theyll instinctively use it.4. CATS ARE INDEPENDENTOne of the best things about cats is that they are very independent creatures. Unlike dogs, who require quite a high level of attention each day, cats are quite happy to have time to themselves. In fact, cats will sleep for about 15 hours a day so you dont have to worry about them being too bored when youre at work. When you are home, cats are also more likely to be content with just being in your company, whereas dogs may demand your undivided attention.5. CATS HAVE A LONG LIFESPANAny pet owner knows that losing a pet is a truly heartbreaking experience. Fortunately, when it comes to house pets, cats have quite a long life expectancy. The average life span of a cat is 12 years, but its not uncommon for them to live into their high teens or even early twenties. Why is freedom so important to America (Canada) as a country?
