Is the answer (-1,1)???

Answer:

D. X > 43

Step-by-step explanation:

You do not know the number of waffle cones sold yesterday, so let's make that the X.

The question says "sold more than 43" so we need an X and a 43.

But which sign to use?

The question says "more than 43" so that means X is bigger

The alligator > wants to eat the bigger number, so you use:

X > 43

Answer:

x > 43

Answer:

Domain: The set of 0

Range: The set of 16

Step-by-step explanation:

A real-world example of a relation that is a function is

Domain: The set of voters.

Range: The set of candidates.

during an election.

A function is a relationship from a set of inputs called domain to a set of outputs called range, such that not more than one value is assigned to an input.

For the given example we understand that each state has two senators hence the relation is not a function.

A real-world example of a relation that is a function is

Domain: The set of voters.

Range: The set of candidates.

during an election.

This is a function because one voter can vote for only one candidate.

7. g(3) = 42

8. f(6) = - 124

9. g(15) = 3

10. h(-3) = 1/8

7. g(x) = 4x² + 6

g(3) = 4×3² + 6

= 4×9 + 6

= 36 + 6

= 42

8. f(x) = - 3x² - 4x + 8

f(6) = - 3×6² - 4×6 + 8

Answer:

QR = 37

ST = 37

Step-by-step explanation:

length of all sides are equal

so QR = ST

3y + 19 = 6y + 1

combine like terms

19 -1 = 6y - 3y

18 = 3y

y = 18/3

y = 6

QR = 3(6) + 19

QR = 37

ST = 6(6) + 1

ST = 37

Answer:

QR = 37

ST = 37

Step-by-step explanation:

QR = ST

3y + 19 = 6y + 1

19 -1 = 6y - 3y

18 = 3y

y = 18/3  = 6

substitute

QR = 3(6) + 19  = 37

ST = 6(6) + 1  = 37

Answer: 2. To avoid bias

Explanation:

The random sampling can be defined as the method of selecting the samples from the population of interest randomly. The main advantage of this method is to select the samples from the target population and eliminating the bias in sampling. The random sampling is least choice of sampling for research purpose as the researcher wants to choose only selected desired samples for the study.

Answer:

Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.

Answer: X-axis

Step-by-step explanation: You can use the "Desmos Graphing Calculator".

Step-by-step explanation:

f(x) = 4x - 1

g(x) = 3x - 2

1) f(x) + g(x) = (4x - 1) + (3x - 2)

= 4x - 1 + 3x - 2

= 4x + 3x -1 - 2 = 7x - 3

2) f(x) * g(x) = (4x - 1) * (3x - 2)

= 12x^2 - 8x - 3x + 2

= 12x^2 -11x + 2

3) f(g(x)) = 4(3x - 2) - 1

= 12x - 8 - 1

= 12x - 9

4) f(x) - g(x) = (4x - 1) - (3x - 2)

= 4x - 1 - 3x + 2

= 4x - 3x - 1 +2

= x + 1

Whenever you're in doubt about the equivalence of numerical expressions, you can use your calculator to evaluate them. They will give the same result if they are equivalent. (You need a good scientific or graphing calculator that uses parentheses for this. Some seriously good calculators are available as low-cost phone apps.)

The value of k is equal to -5.5

In Mathematics and Geometry, the nth term of an arithmetic sequence can be calculated by using this equation:

[tex]a_n=a_1+(n-1)d[/tex]

Where:

Based on the the common difference of an arithmetic sequence, we have:

k - 2 - 3k = k + 7 - (k - 2)

-2k - 2 = k + 7 - k + 2

-2k - 2 = 9

-2k = 11

k = -11/2

k = -5.5

Answer:

(-1,-4)

Step-by-step explanation:

USE A1 + A2 / 2 AND B1 + B2 / 2

A1 + A2 / 2

= (-6+4) / 2

= -1

B2 + B1 / 2

= (-6+(-2)) / 2

= -8 / 2

= -4

therefore, (-1,-4) is your midpoint.

If  all prime numbers are odd, then 2 is  odd.

2 is not odd.

Therefore, it is not the case that all prime numbers are odd.

Step-by-step explanation:

Considering part A

 The  first sentence is  

If all computer programs contain errors, then this program contains an error.

   The second sentence is

This program does not contain an error.

     The third  sentence is

Therefore, it is not the case that all computer programs contain errors.

Now we will use  a and  b  as the letter to denote the component sentences and   [tex]\neg a[/tex]  and [tex]\neg b[/tex] when the component sentences is not the case

So  a =  If all computer programs contain errors

and  

     b =  this program contains an error.

Generally then is represented as [tex]\to[/tex]

Hence the first sentence is denoted as  

         [tex]a \to b[/tex]

The  second sentence is represented as

            [tex]\neg b[/tex]

The  third sentence is represented as

           [tex]\neg a[/tex]

So part a can be represented as

      [tex]a \to b[/tex]

         [tex]\neg b[/tex]

         [tex]\neg a[/tex]

Considering part B

Here the objective is to fill in the blank spaces so that the logic of the sentence in part b is as that in part a

    Now comparing the second statement  a and  b

                "This program does not contain an error" = "2 is not odd" = [tex]\neg b[/tex]

Hence      "this program contains an error." =  "2 is  odd" =  b

     Now comparing the third  statement  a and  b

Therefore, it is not the case that all computer programs contain errors.  

                                                =

     Therefore, it is not the case that all prime numbers are odd  

                                                =

                                                [tex]\neg a[/tex]

Hence

If all computer programs contain errors, = if all prime numbers are odd.= a                

Answer:

212.54

Step-by-step explanation:

To find the mean, we take the sum of all numbers and divide by the total amount in the set

Total sum: 4676

Numbers in the set: 22

4676 divided by 22 = approx. 212.54

Answer:

9.29

Step-by-step explanation:

S₄ is the area using Simpson's rule and 4 intervals.

Simpson's rule can be calculated as:

Sᵢ = Δx/3 (f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + ... + 4f(xᵢ₋₂) + 2f(xᵢ₋₁) + f(xᵢ))

Or, Simpson's rule can be calculated as a combination of midpoint and trapezoid sums:

S₂ᵢ = (2Mᵢ + Tᵢ) / 3

Using the first method:

Δx = (4−0)/4 = 1

S₄ = 1/3 (1.00 + 4(1.41) + 2(2.24) + 4(3.16) + 4.12)

S₄ = 1/3 (27.88)

S₄ ≈ 9.29

Using the second method:

S₄ = (2M₂ + T₂) / 3

The midpoint area for 2 intervals is:

M₂ = (2) (1.41) + (2) (3.16) = 9.14

The trapezoid area for 2 intervals is:

T₂ = ½ (1.00 + 2.24) (2) + ½ (2.24 + 4.12) (2) = 9.60

Therefore:

S₄ = (2 (9.14) + 9.60) / 3

S₄ ≈ 9.29

Wrong 1 5 6 4

Step-by-step explanation:

Answer:

73.1 inches

Step-by-step explanation:

We solve for this using z score formula.

z-score is z = (x-μ)/σ,

where x is the raw score,

μ is the population mean

σ is the population standard deviation.

x = unknown = randomly selected male's height

μ = 70.3 inches

σ = 4.1 inches

z = is not given but we are given its percentile which is 75

The z score for a 75th percentile = 0.674

Hence,

0.674 = x - 70.3/4.1

Cross Multiply

0.674 × 4.1 = x - 70.3

2.7634 = x - 70.3

x = 70.3 + 2.7634

x = 73.0634 inches

The height of the randomly selected male = 73.0634

Therefore, the height of the randomly selected male to the nearest tenth of an inch is 73.1 inches
