Answer:

I think it's 3x + 5 = 21 because three times a number would be 3x so that would eliminate options 2 & 4, then it says five more than three which would be adding five so that would only leave option 1 so that should be your answer

The selling price of the bicycle in discuss upon addition of the mark-up which is 33.3% as described in the task content is; $131.63.

The wholesale cost price of the bicycle in discuss is $98.75 as described in the task content while the markup for the bicycle is as given in the task content.

On this note, it follows that the selling price of the bicycle is the sum of its cost price and it's mark-up. Hence, we have;

Selling price = $98.75 + (33.3% of $98.75)

= $98.75 + (0.333 × $98.75)

= 98.75 + 32.88

= $131.63.

Ultimately, selling price of the bicycle in discuss upon addition of the mark-up which is 33.3% as described in the task content is; $131.63.

The area of the given square is a 9.

According to the statement

We have to find that the area of the square.

So, For this purpose, we know that the

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

From the given information:

The square ABCD with the side AB=3cm. A 3cm B D C​

Then

we know that the all the sides of the square all equals.

Then

AB=3cm = BC=CD=DA

Then

Area of the square = side*side

Area of the square = 3*3

Now,

The value of the Area of the square = 9.

So, The area of the given square is a 9.

Answer:

Step-by-step explanation:

Work from left to right.

24* (-2)*5/(-6)= -48*5/(-6)

-48*5/(-6)=-240/(-6)

-240/(-6)=40

0.620  is the probability that the animal Fran picks is poisonous or is a snake .

How does probability explain work?

Total animal = ( 6 + 8 + 11 + 4 ) =  29

Let,  p = Event of poisonous animal

        s = event of spider

     p U s = event of poisonous or spider

      p ∩ s = event of poisonous or spider

n(P)   =  No of poisonous = ( 6 + 11 ) = 17

n(S)    =  No of spider =   ( 8 + 4 ) = 12

n(P ∩ S)  No of poisonous spider = 11

Then ,    P [ P ] = 17/29       , P [S ] = 12/29     P [ P ∩ S ] = 11/29

   P [ poisonous or spider ]

 = P [ P ∪ S ] = P [P] + P [ S ] - P [ P ∩ S  ]

                     = 17/29  + 12/29 - 11/29

                      =  18/29  = 0.620

given,(2,8)(-4.-7)and their weighted average is 3:5

Weighted average is a calculation that takes into account the varying degrees of importance of the numbers in a data set. In calculating a weighted average, each number in the data set is multiplied by a predetermined weight before the final calculation is made.

(2,8)x5=10+40

           =50

(-4,-7)x3=-12-21

a) The first five terms of the sequence are 1, 3, 9, 27 and 81.

b) The first five terms of the sequence are 1, - 1, - 3, - 5 and - 7.

c) The first five terms of the sequence are 1, 3, 7, 15 and 31.

d) The first five terms of the sequence are 1, 2, 5, 26 and 677.

e) The first five terms of the sequence are 1, 3, 7, 13 and 21.

Recurrence formulas are expressions that generates an element of a sequence in terms of previous elements of the series. Now we proceed to calculate the first elements of each sequence:

Case A

n = 1

a(1) = 1

n = 2

a(2) = 3 · a(1)

a(2) = 3

n = 3

a(3) = 3 · a(2)

a(3) = 9

n = 4

a(4) = 3 · a(3)

a(4) = 27

n = 5

a(5) = 3 · a(4)

a(5) = 81

The first five terms of the sequence are 1, 3, 9, 27 and 81.

Case B

n = 1

b(1) = 1

n = 2

b(2) = - 2 + b(1)

b(2) = - 1

n = 3

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

b(3) = - 3

n = 4

b(4) = - 2 + b(3)

b(4) = - 5

n = 5

b(5) = - 2 + b(4)

b(5) = - 7

The first five terms of the sequence are 1, - 1, - 3, - 5 and - 7.

Case C

n = 1

c(1) = 1

n = 2

c(2) = 2 · c(1) + 1

c(2) = 3

n = 3

c(3) = 2 · c(2) + 1

c(3) = 7

n = 4

c(4) = 2 · c(3) + 1

c(4) = 15

n = 5

c(5) = 2 · c(4) + 1

c(5) = 31

The first five terms of the sequence are 1, 3, 7, 15 and 31.

Case D

n = 1

d(1) = 1

n = 2

d(2) = [d(1)]² + 1

d(2) = 2

n = 3

d(3) = [d(2)]² + 1

d(3) = 5

n = 4

d(4) = [d(3)]² + 1

d(4) = 26

n = 5

d(5) = [d(4)]² + 1

d(5) = 677

The first five terms of the sequence are 1, 2, 5, 26 and 677.

Case E

n = 1

f(1) = 1

n = 2

f(2) = f(1) + 2 · 2 - 2

f(2) = 3

n = 3

f(3) = f(2) + 2 · 3 - 2

f(3) = 7

n = 4

f(4) = f(3) + 2 · 4 - 2

f(4) = 13

n = 5

f(5) = f(4) + 2 · 5 - 2

f(5) = 21

The first five terms of the sequence are 1, 3, 7, 13 and 21.

The longest part is Part B, which is a little longer than Part A.

The length is the measure of distance or total time from one point to another.

For example, when measuring dimensions, the length also shows the longest side of an object, especially the rectangle.

Together with the width, the length can be used to determine the area of an object or its perimeter.

Part                         A          B          C          D

Length (IN.)          1²/₇        1.3         1.15      ²¹/₂₀

Convert all lengths (A and D) into decimals:

Part                         A                 B           C          D

Length (IN.)         1.29 (1²/₇)       1.3         1.15     1.05 (²¹/₂₀)

Part B's length is the most extended length, followed by Part A, Part C, and lastly, Part D.

Thus, the most extended length of the four parts is Part B.

Given the functions f(x) = 1/x and g(x) = x⁴, the function operation ( f + g )(x) is x⁴ + 1/x.

Given the functions in the question;

To evaluate f + g, replace the function designators in f + g with the actual functions and simplify

( f + g )(x) = f(x) + g(x)

( f + g )(x) = ( 1/x ) + ( x⁴ )

Remove the parenthesis

( f + g )(x) = ( 1/x ) + ( x⁴ )

( f + g )(x) = 1/x + x⁴

Reorder 1/x and  x⁴

( f + g )(x) = 1/x + x⁴

( f + g )(x) = x⁴ + 1/x

Given the functions f(x) = 1/x and g(x) = x⁴, the function operation ( f + g )(x) is x⁴ + 1/x.

Answer:

Step-by-step explanation:

Given functions h(x)=x²+1 and k(x)=x-2, you want the values of (h+k)(2), (h-k)(3) and 3h(2)+2k(3).

The value of a function f(x) is found by substituting the argument value for x in the function definition, then doing the arithmetic.

The value of a sum or difference of functions is the sum or difference of the values of those functions for the given argument.

  (h+k)(2) = h(2) +k(2) = (2²+1) +(2 -2) = 5 +0 = 5

  (h-k)(3) = h(3) -k(3) = (3² +1) -(3 -2) = 10 -1 = 9

   3h(2) +2k(3) = 3(2² +1) +2(3 -2) = 3(5) +2(1) = 17

Step-by-step explanation:

Angles in a triangle add to 180°.

The residual value with an actual value of 10 and a predicted value of 14 will be 4. Then the correct option is D.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

We know that the difference between the predicted value and to actual value is known as the residual value.

Residual value = Predicted value - Actual value

If the observed (actual) y value is 10, and the predicted value is 14. Then the residual value will be

Residual value = 14 - 10

Residual value = 4

The residual value will be 4. Then the correct option is D.
