If a test requires that you answer either part A or part B. Part A consists of 6 true-false questions, and part B consists of 6 multiple-choice questions with one correct answer out of six. 46720 different completed answer sheets are possible.

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items.

A test requires that you answer either part A or part B.

Part A consists of 6 true-false questions.

i.e.  there are 2 choices to answer each question

Now, the number of ways to answer Part A :  2⁶=64   (1)

Part B consists of 6 multiple-choice questions with one correct answer out of five.

i.e.  there are 6 choices to answer each question.

Now, the number of ways to answer Part B : 6⁶=46656

Now, the number of  different ways to completed answer sheets are possible= 46656+64

=46720

Hence 46720 different completed answer sheets are possible.

By using 3 factors 2, 3, and 7, if we create a product game board with the numbers 4 6 9 14 49 then the missing product is 21.

To solve this problem we have to follow a few steps. First, we should know about factors.

What are the factors?

Factors of a number are such numbers as they can divide the whole number without remaining.

Example: The factors of 24 are 1, 2, 3, 4, 6, 8, and 12.

Now we have to analyze the given numbers,

4 = 2× 2

6 = 2× 3

9 = 3× 3

14 = 2× 7

49 = 7× 7

The factors are 2, 3, and 7. Therefore, the missing product is, 3× 7= 21

So:

f(x) = 2x + 10

To solve for x, we are going to subtract 10 on both sides of the equation:

Answer: [tex](x-5)^2 +(y+4)^2 =25[/tex]

Step-by-step explanation:

The equation of a circle with center [tex](h, k)[/tex] and radius [tex]r[/tex] is [tex](x-h)^2 +(y-k)^2 =r^2[/tex].

So, the equation is [tex](x-5)^2 +(y+4)^2 =25[/tex].

The equation of the circle in the figure is (x-5)²+(y+4)²=25

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

From the figure the circle has a center at (5, -4) and radius 5

The standard form equation of the circle is (x-h)²+(y-k)²=r²

(h, k) is the center of the circle and r is the radius of circle

Plug in the values of center and r

(x-5)²+(y-(-4))²=5²

(x-5)²+(y+4)²=25

Hence, the equation of the circle in the figure is (x-5)²+(y+4)²=25

Answer:

  a. $9,090.91

  b. $10,526.32

Step-by-step explanation:

You want to know the value of your $10,000 savings when the price level (a) increases by 10%, and (b) decreases by 5%.

As the price level goes up, the number of items that can be purchased with a given dollar amount goes down in inverse proportion.

When the price level increases by 10%, it is multiplied by 1 +10% = 1.10. The effective purchasing power of the savings will be inversely proportional to that:

  $10,000/1.10 = $9,090.91 . . . "real value" of savings

When the price level decreases by 5%, it is multiplied by 1 -5% = 0.95. The effective purchasing power of the savings will be inversely proportional, so will be ...

  $10,000/0.95 = $10,526.32 . . . "real value" of savings

__

Additional comment

The price level index is usually normalized to a value of 100 at some specified point in time. An increase of 10% in price level would be reflected in an index value of 100×1.10 = 110. Effectively, this means that what did cost $100 at the reference time now costs $110.

With $10,000, you could have purchased 100 of those items, but now you can purchase only 90.91 of those items. Your purchasing power has changed in inverse proportion to the price level.

For the entire year, $9091 will be spent if prices rise by 10%.

In the event that prices drop by 5% for the entire year, $10,526.32

Integers include zero, a positive natural number, and a negative integer represented by a minus sign. The negative numbers are the inverse additions of the comparable positive numbers.

Given,

If the price index is 100, savings equal $10,000.

a) If prices increase by 10% annually, the following formula will be used to calculate the true value of the savings:

Real Value = Nominal Value x Prior Year CPI / Current Year CPI

According to the CPI:

= 100 + (100 x 10/100)

For the current year, = 110%.

The resultant value will be

= $10000 x 100/110

= $9090.90

b) If prices decline by 5% annually, the following formula will be used to calculate the true value of the savings:

Real Value = Nominal Value x Prior Year CPI / Current Year CPI

According to the CPI:

= 100 - (100 x 5/100)

for the current year, = 95%

Consequently, the true value will be:

= $10000 x 100/95

=$10,526.32

As a result, your savings would actually be worth $9090.90 if prices rose by 10% annually.

Alternatively, if prices fall by 5% over the course of the year, the actual worth of your savings is $10,526.32.

Combinations are also referred to as selections. Combinations imply the selection of things from a given set of things. In this case, we intend to select the objects.

Combination formula

ⁿCr = n! / ((n – r)! r!

n = the number of items.

r = how many items are taken at a time.

Substitute the values in above formula :

15! / 11! (15 - 11)!

= 15! / 11! 4!

= 15 × 14 × 13 × 12 / 4 × 3 × 2

The probability that the student scores an 85 or better and he receive an A in the score is 0.45.

In the question it is given that the professor tells that the student has 90% chance of getting A, if he gets 85 or better in mid term exam.

The student is 50% sure that he will get 85 or better in the examination.

To get the probability of the student scores an 85 or better and he receives an A grade, we use multiplication rule.

P( student getting A grade and 85 or better)= P(getting A) x P(getting 85 or better)

P(getting A)=0.9

P(getting 85 or better)=0.5

= 0.9x0.5

P( student getting A grade and 85 or better)=0.45

The function that gives f(x) = 2x² - 7

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f (14) = 2(14)²−7

Now, here the changing value is 14 according to which the resultant values changes.

g(x) = 1/2x

The given parameters are:

Every item is on sales for half the original price, plus 3 dollars.

In this case, the function f(x) is the 3 dollars added

Let the original price be x

So, we have the following equation

Price = x + 3

Express as a function

f(x) = x + 3

In (A) and (B), we have

g(x) = 1/2x

f(x) = x + 3

The function (f o g)(x) is calculated as

(f o g)(x) = f(g(x))

So, we have

(f o g)(x) = g(x) + 3

Substitute g(x) = 1/2x

(f o g)(x) = 1/2x + 3

(f o g)(x) = 1/2x + 3
