Consider w₁ = -3i and w₂ = -2. What is the result of subtracting w₂ from w₁?

Answers

Answer 1

The result after subtracting w2 from w1 is -3i+2

Given that,

w1=-3i

w2=-2

So,

w1 -w2= -3i-(-2)

         =-3i+2

Here w1 is a complex number and w2 is a normal number. And we know that we can add or subtract a complex number only with a complex number only. And a normal number with a normal one only.

Therefore, the result after subtracting  w2 from w1 is -3i+2.

mr. crandall has assigned a term paper due at the end of the semester. he would like to know the average length of the paper. the data below are the numbers of typed pages from a random sample of 10 term papers. what type of critical value is needed to create a 95% confidence interval for the population mean length of all term papers for this class?

Answers

There is a 95% chance that the mean length of all term papers lies between confidence limits (11.58,17.82) for the given data:

14, 20, 25, 10, 16, 8, 15, 12, 18, 9

We assume the length of paper has an approximately normal distribution.

Sample size = 10

The sample mean for the given data = 14.7

The standard deviation for the given data = 5.04

Critical value is obtained from standard normal distribution at the level of significance 0.05.

The critical value is 1.96.

The 95% confidence interval for the mean length of all term papers is calculated as follows:

P(14.7 - (1.96 x (5.04/√10)) < µ < 14.7 + (1.96 x (5.04/√10))) = 0.95

P(11.58 < µ < 17.82) = 0.95

many states run lotteries, giving away millions of dollars if you match a certain set of winning numbers. how are those numbers determined? do you think this method guarantees randomness? explain.

Answers

The method to determine the numbers is random only if the balls generate numbers in equal frequencies.

The entire process is random and is not generated by a computer or humans.

One of the most important requirements for a random number is independence, as this aids in the establishment of no correlations between successive numbers. It must be ensured that the frequency of occurrence of these random numbers is roughly the same. As a result, it is theoretically difficult to generate a long random number.

The frequency of a repeating event is the number of occurrences per unit of time. It is distinct from angular frequency and is sometimes referred to as temporal frequency. The frequency is expressed in hertz (Hz), which equals one event per second. Because the period is the time interval between events, it is the reciprocal of the frequency.

Answers

The measure of angle 1 is given as follows:

m < 1 = 150º.

How to obtain the measure of angle 1?

From the image given at the end of the answer, we have that two Railroad tracks are transversal to the Olive Street.

Considering that Olive Street is transversal to the parallel lines, we have that the angle 2 forms a linear pair with the angle of 30º.

Linear pairs are supplementary angles, meaning that the sum of their measures is of 180º, hence the measure of angle 2 is given as follows:

m < 2 + 30º = 180º

m < 2 = 180º - 30º

m < 2 = 150º.

Now we have that angles 1 and 2 are alternate interior angles, as they are between the two parallel lines, on the opposite side of the transversal.

Alternate interior angles are congruent, meaning that the measure of angle 1 is given as follows:

m < 1 = 150º.

find the quotient and remainder when 6x^4+ 11x^3+13x^2 -3x+27 is divided by 3x+4. also check the remainder obtained by using the remainder theorem.

Answers

The division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 will have a quotient of 2x³ + x² +3x -5 and a remainder of 47 using the remainder theorem.

What is the remainder theorem

The remainder theorem states that if a polynomial say f(x) is divided by x - a, then the remainder is f(a).

We shall divide the 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 as follows;

x⁴ divided by 3x equals 2x³

3x + 4 multiplied by 2x³ equals 6x⁴ + 8x³

subtract 6x⁴ + 8x³ from 6x⁴ + 11x³ + 13x² - 3x + 27 will give us 3x³ + 13x² - 3x + 27

3x³ divided by 3x equals x²

3x + 4 multiplied by x² equals 3x³ + 4x²

subtract 3x³ + 4x² from 3x³ + 13x² - 3x + 27 will give us 9x² - 3x + 27

9x² divided by 3x equals 3x

3x + 4 multiplied by 3x equals 9x² + 12x

subtract 9x² + 12x from 9x² - 3x + 27 will give us -15x + 27

-15x divided by 3x equals -5

3x + 4 multiplied by -5 equals -15x - 20

subtract -15x - 20 from -15x + 27 will result to a remainder of 47

using the remainder theorem, x = -4/3 from the the divisor 3x + 4

thus:

f(-4/3) = 6(-4/3)⁴ + 11(-4/3)³ + 13(-4/3)² - 3(-4/3) + 27 {putting the value -4/3 for x}

f(-4/3) = (1536/81) - (704/27) + (208/9) + (12/3) + 27

f(-4/3) = (1536 - 2112 + 1872 + 324 + 2157)/81 {simplification by taking the LCM of the denominators}

f(-4/3) = (5919 - 2112)/81

f(-4/3) = 3807/81

f(-4/3) = 47

Therefore, the quotient of after the division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 is 2x³ + x² +3x -5 and there is the remainder of 47 using the remainder theorem.

x - 4 = (2 x - 2 x) + 7

2 x - 2 x = 0:

x - 4 = 7

Add 4 to both sides:

x + (4 - 4) = 4 + 7

4 - 4 = 0:

x = 7 + 4

7 + 4 = 11:

Answer: x = 11

___________________________

Solve for x:

4 - 2 (x - 5) = x - 19

-2 (x - 5) = -2 x + 10:

(-2 x + 10) + 4 = x - 19

Add like terms. 4 + 10 = 14:

-2 x + 14 = x - 19

Subtract x from both sides:

(-2 x - x) + 14 = (x - x) - 19

-2 x - x = -3 x:

-3 x + 14 = (x - x) - 19

x - x = 0:

-3 x + 14 = -19

Subtract 14 from both sides:

(14 - 14) - 3 x = -14 - 19

14 - 14 = 0:

-3 x = -14 - 19

-14 - 19 = -33:

-3 x = -33

Divide both sides of -3 x = -33 by -3:

(-3 x)/(-3) = (-33)/(-3)

(-3)/(-3) = 1:

x = (-33)/(-3)

The gcd of -33 and -3 is -3, so (-33)/(-3) = (-3×11)/(-3×1) = (-3)/(-3)×11 = 11:

Answer: x = 11

Answer:3x-4=2x+7

Step-by-step explanation:

first,  4-2x+10=x-19

        14+19 =x+2x

           33=3x

               x=11

A. 2x+10=8

    2x= -18

      x=-9

B. 3x-9=9

       3x=18

         x=6

C. x+2=2x-3

      3x = 5

         x = 5/3

D. 3x-4 = 2x+7

    3x-2x=7+4

          x=11

Spontaneous dental hydroplosion is a disease makes your teeth spontaneously turn into liquid. To investigate whether a new drug can prevent the onset of this disease, Jim Halpert decided to perform a study in which half of the fourteen employees at Dunder Mifflin Scranton received the drug and the other half received a placebo. Neither Jim nor the employees were told who received which treatment, and the number of times a subjectâs teeth turned into liquid was recorded. This is an example of (A) A double-blind experiment. (B) A matched-paired experiment. (C) An experiment, but neither double-blind or matched-pair. (D) An observational study. In order to make thorough conclusions, the most important condition for statistical inference is usually that (A) the population distribution follows a Normal distribution exactly. (B) the data does not contain outliers. (C) the data follows the asymmetric, single-peaked distribution. (D) the data can be treated as a random sample from the population of interest. A study was taken at the large senior living retirement community, The Senior Living Community, found that the average age of residents is 73 years with a standard deviation of 6.1 years. A simple random sample of 100 residents is selected and the sample mean age !Ì("x-bar") of these residents is calculated. you know that the random variable X has approximately a normal distribution because of (A) the central limit theorem. (B) the 68-95-99.7 rule. (C) the population that youâve sampled from does not have a Normal distribution. (D) the law of large numbers.
