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

A.
x < 43
B.
x = 43
C.
x < 49
D.
x > 43

Answers

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

Find:
f(x) + g(x)
f(x) *g(x)
f(g(x))
f(x) - g(x)

Answers

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

When conducting a survey, which of the following is a reason to use a random sample?1. To make cause-and-effect connections2. To avoid bias3. No answer text provided.4. To systematically favors the correct choice over every other choice on each question

Answers

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.

Assume the heights in a male population are normally distributed with mean 70.3 inches and standard deviation 4.1 inches. If a randomly selected male’s height is at the 75th percentile, how tall is he (to the nearest tenth of an inch)?

Answers

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

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

Find k if 3k, k-2, and k + 7 are consecutive terms of an arithmetic sequence.

Answers

This is 1:25 (C)

Explanation:

The value of k is equal to -5.5

How to calculate the value of k in this arithmetic sequence?

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:

d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.

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

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

Im so mean I make medicine sick. Muhammad AliMuhammad Ali was an all-time great boxer and entertainer. He was a three-time world heavyweight champion, an Olympic gold medallist, and as masterful approaching a microphone as he was in the ring. Later in life, he was made a United Nations Messenger of Peace, and awarded the United States Presidential Medal of Freedom.Hes widely celebrated today, but that wasnt always true during his boxing career. Ali was a confident, capable, Black Muslim athlete who was unafraid to speak his mind and stand up for his ideals. That made him very unpopular with a lot of people in 1960s America.Ali once said, I am America. I am the part you wont recognize. But get used to me. Black; confident; cocky; my name, not yours. My religion, not yours; my goals, my own. Get used to me.Born Cassius Clay in Louisville, Kentucky in 1942, he changed his name when he became a Muslim. He explained that Cassius Clay is a slave name. I didn't choose it and I don't want it. I am Muhammad Ali, a free nameit means beloved of God, and I insist people use it when people speak to me and of me.In 1966, Ali was at the height of his success as a boxer. At the same time, the US was fighting a war in Vietnam. The government was drafting young men to fight, which meant they had to join the Armed Forces when called. Refusing without an officially allowed reason was illegal. Ali was drafted, but refused anyway. He said he wouldnt fight in Vietnam because it was against his religion and because Black people in America were still "treated like dogs and denied simple human rights.Most Americans supported the Vietnam war at that time, and some thought Ali was a traitor. TV host David Susskind called him a disgrace to his country, his race, and what he laughingly describes as his profession. Ali was stripped of his heavyweight title, disqualified from fighting, and given a $10,000 fine and a prison sentence. But to many, he was a hero. Civil rights leader Reverend Al Sharpton said, he knew he was going to jail and did it anyway. That's another level of leadership and sacrifice.By resisting injustice and inequality, and by never apologizing for who he was, Muhammad Ali inspired countless peopleespecially Black Americans and athletes. Basketball legend Kareem Abdul-Jabbar said, Ali's impact on young people was very formidable . . . The fact that he was proud to be a Black man, and that he had so much talent . . . made certain people love him and made other people think that he was dangerous. But, for those very reasons, that's why I enjoyed him.Ali returned to boxing in 1971 and won back his heavyweight title in 1974. After retiring in 1981, he invested much of his time into supporting different causes. In 1984, he was diagnosed with Parkinsons, and raised money for research into the disease. He traveled the world bringing food and medicine to poor countries. He also contributed his energies to many different charities, including the Special Olympics, and the Make-a-Wish Foundation.Throughout his life, Ali set the standard for being true to yourself and fighting for what you believe is right. Or, in his own words, I know where Im going and I know the truth, and I dont have to be what you want me to be.
