The probability that the mean weekly wage of a randomly selected group of 16 workers from the factory will be within $3 of the population mean wage is 0.98

To solve this problem,

We can use the central limit theorem which states that the sample means from a large sample will be approximately normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

First, we need to find the standard error of the mean, which is equal to the standard deviation divided by the square root of the sample size:

Standard error of the mean = 5 / sqrt(16) = 1.25

Next, we need to find the z-score for the lower and upper bounds of the sample mean:

lower z-score = (402 - 405) / 1.25 = -2.4

upper z-score = (408 - 405) / 1.25 = 2.4

We can use a standard normal distribution table or a calculator to find the probabilities associated with these z-scores:

lower probability = 0.0082

upper probability = 0.9918

To find the probability that the sample mean is within $3 of the population mean we need to subtract the lower probability from the upper probability:

Probability = 0.9918 - 0.0082 = 0.9836

Answer: The expression 6xy - 3xy can be simplified to 36 if x = 3 and y = 4.

Step-by-step explanation:

First let's simplify the problem.

6xy - 3xy = 3xy

3xy

Now let's substitute x for 3 and y for 4.

3 x 3 x 4

Finally, let's solve using the associative property!

  (3 x 3) x 4

= 9 x 4

= 36

  3 x (3 x 4)

= 3 x 12

= 36

The expression 6xy - 3xy can be simplified to 36.

Answer: P(X=28) ≈ C(100, 28) * (1/4)^28 * (3/4)^72 ≈ 0.0368 (rounded to 4 decimal places)

Step-by-step explanation:

Using the binomial probability formula:

P(X=k) = C(n, k) * p^k * (1-p)^(n-k)

Where:

n = 100 (number of trials)

k = 28 (number of successes)

p = 1/4 (probability of success for each trial, since there are 4 sides)

C(n, k) = n! / (k! * (n-k)!)

Plugging the values:

P(X=28) ≈ C(100, 28) * (1/4)^28 * (3/4)^72 ≈ 0.0368 (rounded to 4 decimal places)

Answer:

\(\huge\boxed{\sf x = -100}\)

Answer:

A'(-3,0) ; B'(0,0); C'(3,6) ; D'(-3,6)

Step-by-step explanation:

O(-6,-6)

A( -5 , -4)  = A( -6+1 , -6 + 2)

A'(-6+3 ,-6+6) = A'(-3,0)

B(-4,-4) = B(-6+2 , -6+2)

B'(-6+6,-6+6)= B'(0,0)

C(-3,-2) = C(-6+3, -6+4)

C'(-6+9 , -6+12) = C'(3,6)

D(-5 , -2) = D(-6+1 , -6 +4)

D'(-6+3, -6+12)=D'(-3,6)

Answer:

y = 5/3x + 13/3

Step-by-step explanation:

slope intercept form is y = mx + b

to find the slope of a line using two points, you use the formula

m = (y2-y1)/(x2-x1)

(-2,1) (1,6)

(6 - 1)/(1 + 2)

5/3 is the slope

to solve for b, you take one of the points in the given and the slope (m) and solve for b

y = mx +b

y = 5/3x + b

6 = 5/3(1) + b

6 = 5/3 + b

18/3 = 5/3 + b

13/3 = b

now put the entire equation together

y = 5/3x + 13/3

In the experiment, the subject whose behavior is being assessed are observational units. The observational unit in this instance is Harley (Dog).

We will first investigate if canines can comprehend both non-human and human gestures in this investigation. The dogs were placed around 2.5 meters apart from the experimenter so that the researchers could test this. Two glasses were placed one on either side of the experimenter.

A gesture would be made at one of the cups by either the experimenter (pointing, bowing, or staring) or by a non-human object (a mechanical arm pointing, a doll pointing, or a stuffed animal looking). After then, the scientists would observe whether the dog would approach the cup that was pointed out. Six dogs were put to the test. We'll focus on one of the dogs who participated in both of his trial sets.

The four-year-old mixed breed dog was given the name Harley. Each of the ten trials in a set consisted of one gesture and one pair of cups. In order to see if Harley would approach a particular cup, the experimenter bowed toward it during one round of experiments.

The correct option A, "None of the associations listed are correct," is the appropriate response.To determine the association suggested by the two-way table, we need to calculate the relative frequency of the data.

The table provides information about whether individuals have a brother and a sister.

Based on the options given, let's calculate the relative frequencies to see which association is suggested:

Calculate the relative frequency for individuals who have a brother and a sister:Relative frequency = (Number of individuals with both a brother and a sister) / (Total number of individuals)

Calculate the relative frequency for individuals who have a brother but no sister:Relative frequency = (Number of individuals with a brother but no sister) / (Total number of individuals)

Calculate the relative frequency for individuals who have a sister but no brother:Relative frequency = (Number of individuals with a sister but no brother) / (Total number of individuals)

Calculate the relative frequency for individuals who have neither a brother nor a sister:Relative frequency = (Number of individuals with neither a brother nor a sister) / (Total number of individuals)

By comparing the relative frequencies, we can determine which association is suggested by the data.Unfortunately, the given two-way table is missing, so we cannot perform the necessary calculations to determine the association.

Let x = Number of water bottles

y = Number of hats

The club wants to raise $1200.

i.e. Required equation : 4x+6y=1200

At x=0,

\(0+6y=1200\Rightarrow\ y=\dfrac{1200}{6}\Rightarrow\ y=200\)

At x= 300

\(4(300)+6y=1200\\\Rightarrow\ 1200+6y=1200\Rightarrow\ 6y=0\Rightarrow y=0\)

At x= 240

\(4(240)+6y=1200\\\Rightarrow\ 960+6y=1200\Rightarrow\ 6y=240\Rightarrow y=40\)

So,three ordered pairs(x,y) that exist on the line : (0,200), (300,0) and (240,40)

Step-by-step explanation:

The rate at which the average revenue is changing at x = 177 (the quantity of belts produced and sold) is approximately -0.0345.

To discover the rate at which the average income is changing, we ought to differentiate the income function and after that assess it at the given amount of belts.

The income work is given as:

R(x) = 65x^(9/10)

To discover the normal income, we partition the whole income by the amount of belts delivered and sold. So, the normal income work, AR(x), is:

AR(x) = R(x) / x = (65x^(9/10)) / x = 65x^(-1/10)

To discover the rate at which normal income is changing, we got to separate the normal income work, AR(x), with regard to x.

d/dx [AR(x)] = d/dx [65x^(-1/10)]

Utilizing the control run the show of separation, ready to rework this as:

d/dx [AR(x)] = -1/10 * 65x^(-1/10 - 1) = -6.5x^(-11/10)

Presently, we will assess the subordinate at x = 177 (the amount of belts delivered and sold) to discover the rate at which normal income is changing:

d/dx [AR(x)] = -6.5(177)^(-11/10)

Calculating this value will give us the required result of -0.0345.

The correct ICD-10-CM code for acute peptic ulcer of the stomach with perforation is K25.1. This code represents gastric ulcer with perforation, which is a serious and potentially life-threatening condition that requires immediate medical attention.

K25.5 represents chronic or unspecified gastric ulcer with hemorrhage. This code would not be appropriate for the acute condition with perforation.

K25.9 represents an unspecified gastric ulcer without hemorrhage or perforation. This code does not specify whether the ulcer is acute or chronic and does not indicate the presence of perforation, which is a critical complication.

K25.2 represents duodenal ulcer with perforation, which is a different type of ulcer and location than the acute peptic ulcer of the stomach with perforation.

Accurate and specific coding is essential for appropriate diagnosis, treatment, and payment. Therefore, it is important for medical coders to carefully review medical documentation to accurately assign the appropriate ICD-10-CM code. In the case of acute peptic ulcer of the stomach with perforation, the correct code is K25.1.

The rate at which they are moving apart is the sum of their individual speeds, which is 9 ft/s.

To determine the rate at which the man and woman are moving apart, we consider their individual velocities. The man is walking south at a constant speed of 5 ft/s, which can be represented as a velocity vector v_man = -5i, where i is the unit vector in the north-south direction. The negative sign indicates the southward direction.

Similarly, the woman is walking north at a constant speed of 4 ft/s. Since she starts from a point 100 ft due west of point P, her velocity vector v_woman can be represented as v_woman = 4i + 100j, where i and j are unit vectors in the north-south and east-west directions, respectively.

To find the relative velocity between the man and woman, we subtract their velocity vectors: v_relative = v_woman - v_man = (4i + 100j) - (-5i) = 9i + 100j. This represents the rate at which they are moving apart.

The magnitude of the relative velocity is the rate at which they are moving apart, given by |v_relative| = sqrt((9)^2 + (100)^2) = sqrt(8101) = 9 ft/s.
