The capital gains his earned is $2,625

What is capital gains?
Capital gain is the profit obtained from the sale of assets whose value is higher or increased than when the asset was purchased.

The first is to calculate the difference price when selling and purchasing.

= ((100% + 20%) × $52.50) - $52.50

With the substitution formula, we can simplify it to:

= 20% × $52.50
= $10.5

Next is to multiply the difference price to share he purchased.

= $10.5 × 250
= $2,625

Thus, the capital gains his earned is $2,625

Using the normal distribution, it is found that there is a 0.5899 = 58.99% probability that on any given day it will take between 34 and 44  minutes to complete the task.

In a normal distribution with mean  and standard deviation, the z-score of a measure X is given by:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean.  

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

Mean of 40 minutes, hence μ =40 .

Standard deviation of 6 minutes, hence σ=6 .

The probability that on any given day it will take between 34 and 44  minutes to complete the task is the p-value of Z when X = 44

subtracted by the p-value of Z when X = 34, hence:

X = 44:

[tex]Z={\frac{x-\mu}{\sigma} }[/tex]

[tex]Z={\frac{44-40}{6} }[/tex]

  =4/6

Z =0.67 has a p-value of 0.7486

X = 34:

[tex]Z={\frac{x-\mu}{\sigma} }[/tex]

[tex]Z={\frac{34-40}{6} }[/tex]

Z=-6/6

Z=-1 has a p-value of 0.1587

0.7486 - 0.1587 = 0.5899.

0.5899 = 58.99% probability that on any given day it will take between 34 and 44  minutes to complete the task.

As the sample size gets larger, the z value increases therefore we will more likely to  less likely to fail to reject the null hypothesis, thus the power of the test increases.

Statistical tests provide a mechanism for making quantitative decisions about one or more processes. The intent is to determine whether there is sufficient evidence to "reject" speculations or hypotheses about the process. If you want to keep pretending that you "believe" the null hypothesis is true, then not rejecting it can do you good. Alternatively, it may indicate that there is not yet enough data to "prove" something by rejecting the null hypothesis. A classic application of statistical testing is process control studies. Suppose a manufacturing process is interested in  a photomask with an average linewidth of 500 microns. The null hypothesis in this case is that the average linewidth is 500 microns. This statement implies the need to characterize photomasks with average linewidths much larger or  smaller than 500 microns. This leads to the alternative hypothesis that the average linewidth is not equal to 500 microns. This is a two-way substitution as it protects against substitution in the opposite direction. In other words, the line width is either too small or too large.

A water park water ride would pump 4,00,000 gallon of water in 100 minutes.

In this question, we have been given a water park water ride pump 8000 gallon of water every 2 minute.

So, the amount of water pumped in 1 minute would be,

8000/2 = 4000 gallon

We need to find the amount of water the ride would pump in 100 minute.

By unitary method the required amount would be,

A = 4000 * 100

A = 4,00,000 gallon

Therefore, the ride would pump 4,00,000 gallon of water.

The yield on a corporate bond with a face value of $1000 after removal of discount would be =$60.

Interest rate can be defined as the payment received by an individual after investing a particular amount of money for a given period of time.

The principal amount after removal of $950 discount = $1000

The rate of interest (R) = 6%

The time of investment (T) = 1

Then the simple interest;

= P × T × R/100

= 1000 × 1 × 6/100

= 6000/100 = $60

Jim needs a score of 115 on his third test to keep an average of 89 or greater.

A mean represents the average value among a set of values.

Mean = (sum of all values)/(total number of values)

In other words, mean is the value assigned to each member of set after fair distribution. It means that if a set of n values has a mean of x, we can assume the set to be 'x' value recurring n times over the sample.

In this case, we have 3 test results: 83, 69 & x, where x is the unknown result of 3rd test. Our required minimum average/mean is 89.

Substituting these in our formula for mean, we get:

AS per the concept of trigonometric ratios for theta, the value of cos θ = 2√6/5 , tan θ = -1/2√6 , cosec θ = -5, sec θ = 5/2√6 and the value of cot θ = -2√6.

Trigonometric ratio:

In math, there are six trigonometric ratios they are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given,

The angle theta is in standard position with a terminal arm in quadrant IV. If sin θ =-1/5.

Now, we have to find the remaining five trigonometric ratio of the θ.

As we know that,

sin²θ + cos²θ =  1

Here we know that value of sin θ = -1/5, then the value of cos θ is calculated as,

=> (-1/5)² + cos² θ = 1

=> 1/25 + cos² θ = 1

=> cos² θ = 1 - 1/25

=> cosθ = √24/25

=> cos θ = 2√6/5

So, the value of tan θ = -1/2√6

For the function F(x, y) = x³ + y³ - 3x² - 6y² - 9x ,  the local maximum value is 5 and the local minimum value is -3. The graph is discontinuous, so we cannot locate the saddle points.

In mathematics, a saddle point or minimax point is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function.

We have the following function -

F(x, y) = x³ + y³ - 3x² - 6y² - 9x

We will plot the 3 dimensional graph of this function. From the model it can be seen that, the local maximum value is 5 and the local minimum value is -3. Since the graph is discontinuous, we cannot locate the saddle points.

Therefore, for the function F(x, y) = x³ + y³ - 3x² - 6y² - 9x ,  the local maximum value is 5 and the local minimum value is -3. The graph is discontinuous, so we cannot locate the saddle points.

The t-score of 2.779 is used to find the 99% confidence interval for the population mean.

Given,

Assume that orangutans' heights, measured in inches, are regularly distributed with an unidentified mean and standard deviation. The population means are calculated using the orangutan heights of 27 orangutans that were randomly selected.

What t-score should be applied to determine the population mean's 99% confidence interval?

n = 27

confidence level = 0.99

We have to find a critical value for the confidence level of 0.99.

To find the critical value we need degrees of freedom and significance level.

df = n-1 = 27 - 1 = 26

α = 1 - 0.99 = 0.01

α/2 = 0.01/2 = 0.005

Answer: y = -2x -2

Step-by-step explanation:

First, we want to find the slope. We can see that every time x goes up by one, y goes down by two. Slope is y/x, so we can say that the slope is -2/1 or just -2. Now we have y = -2x + b. To find b, we need to plug in one of the points in the chart. We will use (1, -4). So:

-4 = -2(1) + b

-4 = -2 + b

-2 = b

Therefore our b is -2, making the linear function equate to: y = -2x -2.

The probability that if we select 4 fish from the tank, at least 2 will be white is 0.7863.

Given,

A fish tank in a pet store has 21 fish in it. 9 are orange and 12 are white. determine the probability that if we select 4 fish from the tank, at least 2 will be white;

The probability that the fish is white = 12/21

                                                      = 4/7

To find the probability that at least two will be white,

P(x ≥ 2) = 1 - P(x < 2) = 1 - ( P(0) + P(1) )

The binomial distribution formula [tex]P(x) = (^n_x)p^xq^n^-^x[/tex] where p is the probability of success and q is the probability of failure.

From the above formula;

P(x ≥ 2) = 1 + [ (3/7)⁴ + 4*(4/7)*(3/7)³ ]

            = 0.7863

Hence, the likelihood that if we select 4 fish from the tank, at least 2 will be white is 0.7863.
