Seyall Industries recently tested some of its employees for drug use. It's likely that these tests weren't conducted at random, but rather because of a solid suspicion or solid evidence. This statement is false.

Employers may have reasonable suspicion or probable cause to conduct drug tests on employees in a variety of situations, such as when an employee exhibits behavior that suggests drug use or when an employee has been involved in an accident or incident that may be related to drug use.

Additionally, some industries may require drug testing as a condition of employment or as part of safety regulations. It is important for employers to have a clear drug testing policy in place that outlines the circumstances under which testing may be conducted, the procedures for conducting tests, and the consequences for positive results.

Employers should also ensure that they comply with any applicable laws and regulations regarding drug testing in the workplace. This is because drug testing in the workplace is typically conducted based on specific criteria and is not usually done at random.

Equation 1: x + y = -18

Equation 2: x - y = 38.

The two numbers that Kasey is thinking of are 10 and -28.

To find the two numbers that Kasey is thinking of, we can set up a system of equations based on the given information.

Let's denote the two numbers as x and y.

Equation 1: The sum of the two numbers is -18.

This can be represented as:

x + y = -18

Equation 2: The difference between the two numbers is 38.

This can be represented as:

x - y = 38.

Now, we have a system of two equations with two variables. We can solve this system to find the values of x and y.

One approach to solve this system is by using the method of substitution or elimination.

In this case, we will use the method of elimination.

Adding Equation 1 and Equation 2, we eliminate the y variable:

(x + y) + (x - y) = -18 + 38

2x = 20

x = 10

Substituting the value of x into Equation 1:

10 + y = -18

y = -28

Therefore, the two numbers that Kasey is thinking of are 10 and -28.

By solving the system of equations, we found that one number is 10 and the other number is -28.

These values satisfy the conditions given in the problem, where their sum is -18 and their difference is 38.

The  probability that a 3 standard deviation event never occurs out of 1000 trials is approximately 2.3 × 10^-6.

Assuming that the probability of a 3 standard deviation event occurring in a single trial is low, we can use the binomial distribution to estimate the probability that such an event never occurs out of n trials.

Let p be the probability of a 3 standard deviation event occurring in a single trial. Since a 3 standard deviation event is defined as an event that is 3 standard deviations away from the mean, we can use the standard normal distribution to calculate this probability. The probability of a standard normal random variable being greater than 3 is approximately 0.0013. Therefore, we can assume that p = 0.0013.

Let X be the number of trials out of n in which a 3 standard deviation event occurs. Then X has a binomial distribution with parameters n and p. The probability that a 3 standard deviation event never occurs out of n trials is given by:

P(X = 0) = (1 - p)^n

Substituting p = 0.0013, we get:

P(X = 0) = (1 - 0.0013)^n

To calculate the probability that a 3 standard deviation event never occurs out of n trials, we need to know the value of n. If n is large, we can use the normal approximation to the binomial distribution. The normal approximation to the binomial distribution states that if n is large and p is not too close to 0 or 1, then X has approximately a normal distribution with mean np and variance np(1-p). In this case, we can use the following formula to estimate the probability that a 3 standard deviation event never occurs out of n trials:

P(X = 0) ≈ Φ((0.5 - np) / sqrt(np(1-p)))

where Φ is the cumulative distribution function of the standard normal distribution.

For example, if we take n = 1000, then np = 1.3 and np(1-p) ≈ 1.2987. Using the above formula, we get:

P(X = 0) ≈ Φ((0.5 - 1.3) / sqrt(1.2987)) ≈ Φ(-4.51) ≈ 2.3 × 10^-6

Therefore, the probability that a 3 standard deviation event never occurs out of 1000 trials is approximately 2.3 × 10^-6.

Answer:

We can solve the simultaneous equation 24n + 9m = 8 and 3n - 2m = 6 by using the elimination method.

First, we need to multiply the second equation by 3 to eliminate n:

24n + 9m = 8

(3n - 2m) × 3 = 6 × 3

9n - 6m = 18

Now we have two equations with the same n coefficient, so we can subtract the second equation from the first to eliminate n:

24n + 9m = 8

-(9n - 6m = 18)

-----------------

15n + 15m = -10

We can simplify this equation by dividing both sides by 5:

3n + 3m = -2

Now we have two equations with the same m coefficient, so we can subtract the second equation from the first to eliminate m:

24n + 9m = 8

-(3n + 3m = -2)

----------------

21n + 6m = 10

We can simplify this equation by dividing both sides by 3:

7n + 2m = 10/3

Now we have two equations with only one variable, so we can solve for one variable and substitute the value into one of the original equations to solve for the other variable:

7n + 2m = 10/3

2m = 10/3 - 7n

m = (10/3 - 7n)/2

Substitute this expression for m into the first equation:

24n + 9m = 8

24n + 9[(10/3 - 7n)/2] = 8

24n + (30/2 - 63n/2)/2 = 8

24n + 15 - 63n/4 = 8

24n - 63n/4 = 8 - 15

(96n - 63n)/4 = -7

33n/4 = -7

n = -28/33

Substitute this value of n into the second equation:

3n - 2m = 6

3(-28/33) - 2m = 6

-28/11 + 2m/11 = 2

2m/11 = 2 + 28/11

2m/11 = 50/11

Answer:

n = 14 / 15
m = -8 / 5

Step-by-step explanation:

24n + 9m = 8   ------- (1)   x 2

3n - 2m = 6  -----------(2)   x 9

48n + 18m = 16    ------- (3)
27n - 18m = 54    --------(4)

Adding two eqn , we get ;
______________

75n = 70
n = 14 / 15

Putting value of n in eqn (2) , we get ;

14 / 5 - 2m = 6
2m = 14 / 5 - 6

2m = -16 / 5

m = -8 / 5

The value of a in the expression is -4.

We have,

8a + 17 = 5a + 5

Combine the like terms.

8a - 5a = 5 - 17

To find the standard form of the complex number, we can use Euler's formula which states that e^(ix) = cos(x) + i sin(x). Using this formula, we can rewrite 5(cos(135°) + i sin(135°)) as 5(e^(i * 135°))

We can then use the fact that e^(ix) = cos(x) + i sin(x) to simplify this expression:
5(cos(135°) + i sin(135°)) = 5(e^(i * 135°)) = 5(cos(135°) + i sin(135°))
So the standard form of the complex number is:
5(cos(135°) + i sin(135°))
To represent this complex number graphically, we can plot the point (5 cos(135°), 5 sin(135°)) in the complex plane. This point has a magnitude of 5 and an angle of 135° (measured counterclockwise from the positive real axis). So the graphical representation of the complex number is a point in the second quadrant of the complex plane, 5 units away from the origin, and making an angle of 135° with the positive real axis.

We fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the death rate for the treatment group is different from the overall death rate of 23%.

The null hypothesis is a kind of hypothesis which explains the population parameter whose purpose is to test the validity of the given experimental data.

To determine if any conditions are met, we need to perform a hypothesis test.

Null Hypothesis (H₀): The death rate for the treatment group is the same as the overall death rate of 23%.

Alternative Hypothesis (Hₐ): The death rate for the treatment group is different from the overall death rate of 23%.

We can use a one-sample proportion z-test to test this hypothesis. The test statistic is calculated as:

z = (p - P) / √(P(1-P) / n)

where p is the sample proportion (15/84), P is the hypothesized proportion (0.23), and n is the sample size (84).

Using these values, we get:

z = (0.1786 - 0.23) / √(0.23 * 0.77 / 84) = -1.76

The corresponding p-value for this test statistic is 0.0788, which is greater than the standard significance level of 0.05. Therefore, we fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the death rate for the treatment group is different from the overall death rate of 23%.

The rate of change of z with respect to time at t = 5 is -16.

Using the chain rule, we can express the total differential of z as dz = fx(3, 2) dx + fy(3, 2) dy. At t = 5, x = g(5) = 3 and y = h(5) = 2, and we know that g′ (5) = 2 and h′ (5) = 4.

Thus, we have dx/dt = g′ (5) = 2 and dy/dt = h′ (5) = 4. Plugging in these values and the given partial derivatives, we have dz/dt = 4(2) + (-6)(4) = -16.

Therefore, the rate of change of z with respect to time at t = 5 is -16.

To explain, we use the chain rule to express the total differential of z as dz = fx(3, 2) dx + fy(3, 2) dy, where fx and fy are the partial derivatives of z with respect to x and y, respectively, evaluated at the point (3, 2).

Then, at t = 5, we use the given information to find the values of x, y, dx/dt, and dy/dt, and we plug these values and the partial derivatives into the total differential to get dz/dt.

This means that Jason is in the 92nd percentile. The answer is d. 92nd.

What is mean?

In statistics, the mean (also known as the arithmetic mean or average) is a measure of central tendency that represents the sum of a set of numbers divided by the total number of numbers in the set.

To calculate the mean of a set of numbers, you add up all the values in the set, and then divide the sum by the total number of values.

Assuming a normal distribution, we know that approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

Since Jason's exam score is 1.41 standard deviations above the mean, we can say that approximately 92% of the data falls below his score (since 1.41 standard deviations above the mean is approximately the same as the mean plus 1.41 standard deviations). This means that Jason is in the 92nd percentile.

The population  scores with a mean of 300 and a standard deviation of 50, approximately 68% of the scores would be expected to fall between 250 and 350.

If a population of scores is normally distributed with a mean of 300 and a standard deviation of 50, we can use the properties of the normal distribution to determine the proportion of scores that would be expected to fall within a certain range.

In this case, we want to find the proportion of scores that fall between 250 and 350.
To do this, we can use the standard normal distribution and the z-score formula.

The z-score is a measure of how many standard deviations a particular score is from the mean. We can calculate the z-scores for 250 and 350 using the formula:
z = (x - μ) / σ
where x is the score we want to find the z-score for, μ is the mean, and σ is the standard deviation.
For 250: z = (250 - 300) / 50 = -1
For 350: z = (350 - 300) / 50 = 1
Once we have the z-scores for 250 and 350, we can use a z-score table or a calculator to find the proportion of scores that fall between these values.

From a standard normal distribution table, we can find that the proportion of scores between -1 and 1 is approximately 0.6827.
Therefore, we would expect to find approximately 68.27% of scores between 250 and 350 in a normally distributed population with a mean of 300 and a standard deviation of 50.

Area of bulletin board = 34 2/3 = (3 * 34 + 2)/3 = 104/3 square feet.

Next, we find the area of each piece of paper:

Area of each piece of paper = (1/3) ft * (1/3) ft = 1/9 square feet.

Now, we can find the number of pieces of paper on the bulletin board by dividing the total area covered by the area of each piece of paper:

Number of pieces of paper = Area of bulletin board / Area of each piece of paper

Number of pieces of paper = (104/3) / (1/9)

Number of pieces of paper = (104/3) * (9/1)

Number of pieces of paper = 936/3

Number of pieces of paper = 312

An "onto" function, also known as a surjective function, maps every element of the domain to at least one element of the codomain. A "one-to-one" function, or injective function, maps each element of the domain to a unique element in the codomain. If f: x → y is onto but not one-to-one, it means that some elements in x have the same corresponding element in y.

To determine if the inverse relation, f^(-1), is a function, let's recall the definition of a function: for every input, there must be exactly one output. Since f is not one-to-one, multiple elements in x correspond to a single element in y. Thus, when considering the inverse relation f^(-1), a single element in y would correspond to multiple elements in x.

In conclusion, f^(-1) would not be a function because it does not satisfy the requirement of having a unique output for each input.

Surface area of the square pyramid is 7 square mi.

A square pyramid is a three-dimensional geometric figure which has a square base and four lateral faces, The lateral faces are triangular faces with a common vertex.

Let us consider a square pyramid, whose side length is "a" and slant height is "h".

Then the area of the base, i.e. area of square shaped base = square unit and the area of each triangular face is (1/2 × a × h) square unit.

So, the sum of areas of 4 triangular faces is 4 × (1/2 × a × h)=2ah square unit.

∴ Surface area of a square pyramid = Area of base + Area of 4 side face

[tex]\sf = (a^2+2ah) \ square \ unit[/tex]

Given that, Side length (a) = 1 mi

And Slant height (h) = 3 mi

∴ Surface area of the given square pyramid = [tex]\sf (1)^2+(2\times1\times3) \ square \ mi[/tex]

[tex]\sf = 1+6 \ square \ mi[/tex]

[tex]\sf = 7 \ square \ mi[/tex]

Step-by-step explanation:

so, from year 0 to year 1 after arrival the population grows by 5% (= factor 1.05).

as growth means the number of people before plus the additional 5%.

so, we multiply 15,400 by (1 + 0.05) or simply by 1.05.

and in year 2 after arrival we multiply that result again by 1.05.

which is the year 0 number multiplied by 1.05 × 1.05 or simply 1.05².

in year 3 after arrival that result gets multiplied by 1.05. or year 0 multiplied by 1.05×1.05×1.05 or simply 1.05³.

and so on, and so on.

so, we get an exponential function with starting value of 15,400 :

y = 15,400 × (1.05)^x

to calculate the local population x years after the arrival of the large company.

for x = 0 we get the starting value of 15,400.
